Blender 3.1 is fast, but how fast does it run on your computer? You can download and run the Blender Benchmark to compare your score with openly accessible benchmarks provided by the Blender community.

In this article, we show you the best GPU for Blender 3.1 in 2022.

As you might know, Blender Benchmark is a platform to collect and display the results of hardware and software performance tests. This benchmark aims at an optimal comparison between system hardware and installations, and to assist developers to track performance during Blender development. In this article today, let’s find out what is the best GPU for the latest version Blender 3.1. 

Below is the Blender 3.1 Benchmark with Cycles on blender.org. The platform only uses free and open-source software, the testing content is public domain, and the test results are being shared anonymized as public domain data – free for anyone to download and to process further.

In this chart, the “spotlights”are  NVIDIA RTX A6000 (48GB VRAM) and RTX 3090Ti (24GB VRAM) – the most high-end cards in the GPU market. Particularly, NVIDIA just announced and released RTX 3090Ti on March 29th (last week), which becomes NVIDIA’s flagship GPU with 10752 CUDA cores. Back to our benchmark chart, it’s unbelievable to see that RTX 3090 claims the top spot at a score of 6036.37. and completely beat the two other NVIDIA flagships. The performance gap is not too large, respectively 5989.54 with 3090Ti  and 5260.35 with RTX A6000, nevertheless, their prices are much more expensive. 

More importantly, it’s nearly twice the performance of the Titan RTX with the same capacity of video memory (Benchmark core: 3542.26).  RTX Titan was only available from NVIDIA with their dual-fan cooling solution, meaning it could not be used effectively in multi-GPU configurations. For your GPU Rendering needs, stick to mainstream RTX GPUs for the best value, especially the beast RTX 3090. Designed for the most demanding gamers, content creators and data scientists, the GeForce RTX 3090 features a record-breaking 10,496 CUDA cores, and boasts 78 RT-TFLOPs, 40 Shader-TFLOPs and 320 Tensor-TFLOPs of power. And It’s packed with 24GB of the fastest 19.5Gbps GDDR6X memory. Try it here!

We think it’s fair to call this card RTX 3090 a “beast”, not only because it will prove to be the fastest gaming and creator GPU on the market, but also because it will take up three PCI slots in your PC. To see how increasing the number of video cards in a system affects performance in Blender, we’re going to max out as well all the GPUs. In these videos, we are going to show you the specs of the machine from 1-6 GPUs.

We download the Benchmark Client and run one of the two benchmarks (‘quick’ or ‘complete’). The benchmark will gather information about the system, such as operating system, RAM, graphics cards, CPU model, as well as information about the performance of the system during the execution of the benchmark. After that, the user will be able to share the result online on the Blender Open Data platform, or to save the data locally.

As technology has advanced, so have the ways for making and experiencing art. More and more artists are creating work digitally, and many of their pieces exist purely as pixels on a screen. However, just because we’re not able to hold these artworks in our hands, it doesn’t mean they’re less valuable. In fact, digital art is quickly becoming one of the most valuable art forms of our time. The art world is rapidly changing with the introduction of NFTs, or non-fungible tokens. In particular, 2021 has seen a spike in digital art sales, with many high-profile artists and brands exploring new ways of selling their work through blockchain technology.

This cute digital cat was sold for 600 ETH, or $200,000 at the time. Today, the same amount of tokens costs around a million dollars.

NFTs have existed since 2015, but they didn’t gain popularity until 2020. Then in 2021, the digital art market really boomed. Now, let us get to the point and dive deeper into what are NFTs, some tips to make your NFT artworks more popular and why iRender is a good choice for NFT community?

NFT stands for “non-fungible token.”  In simple terms, NFTs are the digital record of a sale on a blockchain. 

An NFT refers to the one and only combination of a unique blockchain ‘certificate of ownership’ with an underlying digital artwork file. This technology gives digital art some of the properties of physical art. People can replicate the work just like people replicate Beeple’s “Everydays: The First 5000 Days”, but there is one true “Everydays: The First 5000 Days” and it’s verifiable through a record of ownership going all the way back to Beeple. The artist can replicate and resell a digital artwork file ad infinitum, but the single token can never be replicated. If an NFT is resold, it will retain the ‘chain of title’ from owner to owner forever.

Imagine you’re an artist who signs a one-and-only contract to sell an original artwork at auction, but instead of selling it in a single transaction, you sell the artwork along with the contract attached to it as a digital file. An NFT is the digital equivalent of selling artwork with a ‘signature’ of sale. When you sell an NFT, you’re selling the crypto token record of the work, which means that you, as the artist, can make digital art and sell the original. 

Just like any other digital art, people can take a million screenshots of it, print it and hang it on their wall, and none of those reproductions will reduce the value of the original NFT. In fact, hype around reproductions may increase the value of the NFT by giving it cultural value.

Yes, 3D artists can make money selling their work as an NFT. When the NFT artwork Everydays: The 5000 First Days sold for a record-breaking $69M, digital artist Beeple (Mike Winkelmann) skyrocketed to be the world’s third most valuable living artist and also one of the 10 most expensive NFT artworks of 2021.

People buy NFTs for the same reason they buy physical art or antiques. Aesthetics, a passion for artists, trends, and art-world validations are among the major factors that drive collectors to purchase artworks. Collecting digital items is very similar to collecting physical items — they can be viewed as both a hobby and an investment.

When it comes to selling your artwork as an NFT creator, there is no recipe for making a lot of money, but in this article, we can share with you some factors helping you increase your chances. For example, by analyzing historical data of NFT art on marketplace SuperRare, Artnome identified the search terms that were most popular on the platform as of 2021. Below is their core findings:

• Futuristic, retro, and sci-fi themes are frequently explored and highly coveted by collectors
• 3D  art is the most viewed with higher selling points, perhaps reflecting a ‘medium’ specific to crypto art (the number of views highly correlates with a price)
• As in the traditional art world, NFTs tagged with “drawing” tend to sell for less
• The average color palette of NFTs tends toward purple, reinforcing an aesthetics rooted in technostalgia

Digital artists are getting fed up after years of creating highly interactive content on Big Tech platforms like Facebook and Instagram. However, they receive almost no value at all, which is why many artists plunge into the digital art industry. All of the world’s artists envision a future where NFT will transform both their creative process and the way the world values art.

Regardless of the trends, beginning with your unique style as an artist is always a good place to start. Besides, iRender is a good choice to speed up your render process and spend more time being creative and selling more your 3D NFT arts, like @NFTVERSE2, @MGXS and @RTFKT who are using 8x RTX 3090 on iRender.

There are a variety of servers from single- GPU 1x RTX 3090 to Multi-GPU 2/4/6 x RTX 3090, you can choose one server that is suitable for your demand and your software to get started. At iRender, you fully control the specification, you fully control your powerful workstation, fully control your project and enjoy the unlimited power of Multi GPUs to be more and more creative. Try RTX 3090 now!

Below is the project THE X EVOLUTIONS. Created in collaboration with the Artist MGXS, the X Evolutions is a project by RTFKT studios, a next-gen sneakers studio creating the future of collectible sneakers for the metaverse. An Evolutive digital item you can use to flex in multiple simulations. As of November 2020, it was placed a bid of 22 ETH, or $64,366.28.

When picking from popular marketplaces, we advise you to stick to the biggest ones. The bigger the marketplace is – the greater the exposure for your art.

• OpenSea – It’s @RTFKT’s choice. The world’s biggest marketplace for non-fungible tokens and the first NFT marketplace on the Ethereum blockchain. OpenSea offers NFTs in various categories – from digital art and in-game assets to domain names and sports memorabilia. 

• Rarible – Rarible is a peer-to-peer NFT marketplace that encourages users to engage with each other and comment on the listed NFTs. On the other hand, the site lets artists set ongoing royalty commission rates as high as 30%. 

• SuperRare – SuperRare prides itself on only offering rare, limited edition pieces of art, selected by the marketplace creators themselves. The marketplace is built as a social network, allowing users to interact with the artwork and artists on display. To get on their platform, you will need to get an existing creator to invite you.

Check out a few performance test videos below to find out why iRender is a favorite place for many 3D NFT artists:

Blender has finally leveled up. On December 3, 2021, the Blender Foundation released Blender 3.0 – the first total version change for the incredibly powerful and widespread open-source visual software in over 21 years. There’s a lot of good new stuff in this release. In the last article, we’ve dug into the latest update to take a look at it from Cycles performance perspective. In this article, join us as we throw all of the current-gen GPUs from GeForce and Radeon at Eevee Render and the viewport.

We’ve now moved onto two new animation projects. Of the two, Red Autumn Forest is the more GPU hungry, as it’s not as reliant on the CPU through its render. Splash Fox is different, in that it takes larger breaks in between each frame render to take care of compositing tasks. Let’s see how these projects compare in our testing:

These results are far more interesting than the ones we used to see, Red Autumn Forest uses the GPU more throughout its render process than Splash Fox does. In the test with an RTX 3090, we found that Red Autumn Forest used the GPU 70% of the time through the process, whereas Splash Fox dropped to 40% average usage. The fact that the CPU is involved a lot more in the Splash Fox render is made obvious with the tighter scaling between all of the models.

While NVIDIA won the EEVEE battle against AMD with Mr. Elephant, the gains in Red Autumn Forest are much more pronounced – there’s a clear separation between the vendors. But, in the more complex Splash Fox project, AMD’s Radeons perform great overall. To wrap-up our performance testing, we’re going to set aside rendering to test out the performance in Blender’s viewport in the next part.

We mentioned in the “What’s New?” section of the last article that Blender’s viewport has seen some performance improvement in 3.0, but that’s largely related to using the rendering mode, which is both difficult to measure for benchmarking purposes, and made a little redundant with our numerous actual rendering tests. Most didn’t change too much, but some did.

For simpler projects like the Controller one used here, any one of these listed GPUs is going to deliver good enough performance for working with, but naturally, your camera panning will become much smoother with a higher-end GPU. The Racing Car project is the more complex of the two, which is made evident with the results being at least a third of those that we saw with the Controller project. If you’re working with really complex projects in Material Preview mode, you’ll definitely want a higher-end GPU.

Overall, there’s quite a large performance delta seen between the bottom and top GPUs in both results here, making it a great benchmark.

• RTX 3090: 41 FPS
• RTX 3080 Ti: 40 FPS
• RTX 3080: 35 FPS

With Solid and Wireframe, the GPU is relied upon less, and the CPU is relied upon more. That results in performance that’s far different from Material Preview, as you’ll see below:

Even with the Solid mode being a lot easier on the GPU than the Material Preview mode, there’s still a large difference seen across the stack, but every single one of our tested GPUs can deliver great performance here. If you like smoothness, and have a high refresh monitor, the fastest GPUs here will take good advantage of it. Still, the faster your GPU, the more you will be able to take better advantage of your high-refresh monitor:

• RTX 3090: 259 FPS
• RTX 3080: 258 FPS
• RTX 3080Ti: 254 FPS

Eevee is only going to make use of one of graphic card. The reason is that multiple graphic cards CANNOT work together to render a single frame using rasterization which is what Eevee uses , so it will perform best when it benefits from high VRAM capacity. If EEVEE is your primary application, then we recommend using NVIDIA Geforce graphics cards as they generally have higher performance at a lower cost.

iRender is a Professional GPU-Acceleration Cloud Rendering Service provider in HPC optimization for rendering tasks, CGI, VFX with over 20.000 customers and being appreciated in many global rankings (e.g. CGDirector, Lumion Official, Radarrender, InspirationTuts CAD, All3DP). Moreover, iRender officially joins the Blender Foundation’s Development Fund as a corporate Diamond member.

Based on previous analysis, iRender provides server 3 owning Xeon W-2245 CPU Processor with a high clock speed of 3.9 GHz- 4.7GHz and 512 GB SSD to specifically support the software only make use of a single card. This server comes with the latest RTX 3090 card from NVIDIA with the VRAM capacity up to 24GB.

You can start at 3.8 USD to use the beast RTX 3090. You can rest assured that our pricing schemes are the cheapest you have ever found, with rates three times lower than that of other solutions.

Blender has finally leveled up. On December 3, 2021, the Blender Foundation released Blender 3.0 – the first total version change for the incredibly powerful and widespread open-source visual software in over 21 years. There’s a lot of good new stuff in this release, so in the article today, iRender put together a list of standout facets and features – the biggest and most notable changes – in Blender 3.0 here and find out the best way to speed up the new Cycles.

Improvements to shadows came up a couple of times in the release notes, both in the renewed Shadow Catcher and Shadow Terminator.

The shadow catcher now includes indirect and environment light support, and a pass that can maintain an object’s color when cast. The Blender Foundation says this makes it easier to blend images with real footage.

On the other side of things, the shadow terminator is making clearly digital designs seem just a touch more natural. Blender 3.0 has a new option to eliminate shadow artifacts in low poly models by offsetting rays to act on rigid designs as they would smooth surfaces.

The developers have put some serious effort into simplifying workflows for Blender 3.0 and, aside from fields, that shines brightly in the new and improved Asset Browser.

The new asset browser is a drag-and-drop system that organizes objects, textures, lighting, and poses into catalogs with the ability to add metadata like authors and tags for further simplicity. The assets can be accessed across project files, so users can build up large personal repositories – more features are planned for future updates. The Blender Foundation has said this is simply the “first milestone” for the asset browser and that we can expect a series of “Blender Bundles” soon.

Poses received special attention in the release notes as a time-saving function for animators, too. They can be accessed via the asset browser or the animation panel in 3D view where users can “add, blend, flip, apply, and save different poses.”

Blender 3.0 marks the beginning of a new era for 3D content creation, with new features including a more responsive viewport, reduced shadow artifacts, an asset library to access owned and borrowed assets quickly, and additional customization options. Speaking of Cycles, changes to GPU kernels and scheduling have resulted in “rendering between 2x and 8x faster in real-world scenes”, the Blender Foundation says.  Cycles renderer has been completely overhauled, maximizing NVIDIA RTX GPU RT Cores for OptiX ray tracing and Tensor Cores for OptiX AI denoising. This enables rendering nearly 12x and 15x faster than with a MacBook Pro M1 Max or CPU alone, respectively, with the GeForce RTX 3080 laptop GPU.

Now, let’s check out the comparison between the render speed of Blender versions, with the BMW project.  Here’s a look at CUDA and HIP performance in 3.0.0 vs. CUDA and OpenCL in 2.93.7:

It’s interesting to see that AMD appears to benefit more from this Cycles upgrade than NVIDIA, as its before and after deltas are much starker. The new Cycles especially breathes more life into AMD’s lower-end stack, where GPUs like the RX 6600 and RX 6600 XT effectively see doubled performance! Fortunately, these Cycles improvements extend beyond CUDA and HIP. The CPU also sees some improvement, just not to the extent that we see from the GPUs. And, because GPUs are clearly the most important focus for Blender rendering, CPU gains won’t ultimately matter that much for most people.

The new Cycles even benefits OptiX, not just CUDA. The performance delivered with the new Cycles X is simply staggering. In 3.0, some NVIDIA GPUs become as fast when rendering with CUDA as they were in 2.93 using OptiX (for example RTX 3090, RTX 3080). It takes things one step further again, giving us some seriously impressive performance.

For this article, we’re benchmarking with the BMW, Classroom, as well as the brand-new Blender 3.0 official project, Sprite Fright.  “Sprite Fright” is no doubt the beefiest project to be found on Blender’s demo files page, requiring upwards of 20GB of system memory after it’s opened. Since projects like BMW and Classroom are pretty simple in the grand scheme, we’re happy to be able to now include a comprehensive project like this to test with.

All of the benchmarking conducted for this article was completed using updated software, including the graphics driver. An exception to the “updated software” rule is that for the time-being, we’re choosing to stick to using Windows 10 as the OS, as Windows 11 has so far felt like a chore to use and benchmark with.

Sprite Fright scene

These three sets of results all show similar scaling, with NVIDIA’s GeForces ultimately leading in performance vs. each model’s respective Radeon competitor. Of these four projects, it’s the Sprite Fright one we were keen to analyze most; not just because it’s brand-new, but also because it’s the most complex Blender project we’ve ever tested. As mentioned above, merely opening the project will use upwards of 20GB of system memory.

Sprite Fright‘s resulting render is effectively three renders in one, with each being layered on top of the others in the final composition stage. Due to this design, there’s a slight delay in GPU work in between each of those renders, so we opted to retain default sample and resolution values to make sure the CPU wouldn’t interfere too much with our scaling. That leads to a super-fast GPU like the RTX 3090 taking 10 minutes to render a single frame, and a lower-end RX 6600 taking over 40 minutes.

Conclusion: In NVIDIA’s current-gen lineup, we’d have to say that the GeForce RTX 3090 and the video memory of 24 GB VRAM are the best bang-for-the-buck, given its pricing and performance delivered. Try it here.

As you might know, EEVEE has real-time rendering capabilities that save you a lot of time in post-production, while Cycles is very flexible and brings great realism to the project, not for speed. However, with Multi-GPU settings, Cycles can nevertheless deliver an impressive level of render speed.

In this article, iRender will bring you deep knowledge about GPU rendering in Blender & Cycles. Unfortunately, GPU rendering is only supported on Windows and Linux; macOS is currently not supported.

Multi-GPU Rendering for Blender & Cycles

Always make sure to install the latest drivers from the graphics card manufacturer website. These requirements are for basic Blender operation, Cycles rendering using the GPU has higher requirements.

NVIDIA: GeForce 400 and newer, Quadro Tesla GPU architecture and newer, including RTX-based cards, with NVIDIA drivers (list of all GeForce and Quadro GPUs)

AMD: GCN 1st gen and newer. Since Blender 2.91, Terascale 2 architecture is fully deprecated, try using 2.90 (albeit not supported, it might still work) [list of all AMD GPUs]

Intel: Haswell architecture and newer. [list of all Intel GPUs]

Blender’s heavy use of GPU acceleration and its rock-solid CUDA implementation makes an Nvidia graphics card a safe choice for most users. Non-CUDA cards (read: AMD cards) aren’t the best choice for rendering, but they’re still a good choice for users interested in consistent viewport performance.

If you navigate your Scene a lot by moving around the camera in Blender or playing back animations, Nvidia GPUs are a solid choice because CUDA usually supports more features and performs better. Blender’s development team is actively working with Nvidia to fully integrate OptiX features into Blender and OptiX accelerated CUDA rendering already is available alongside the existing CUDA and OpenCL implementations.

BMW with Multi-GPU Rendering for Blender & Cycles

When it comes to looking at GPU specifications, pay attention to the number of compute-cores (CUDA or OpenCL, depending on what brand you buy) and the amount of VRAM. Blender is just as hungry for VRAM as it is normal RAM, and a GPU with ample VRAM is worth paying extra for if you’re interested in sculpting, high poly modeling, or GPU rendering.

Over the past three years or so, NVIDIA’s dramatically improved the rendering performance in its stack. It was once exciting when the BMW project broke through the 60-second barrier, but now we have these new RTX GPUs cutting through the 30-second mark. The RTX 3090 comes closer to 20 seconds than it does 30 seconds. These new GPUs are really, really fast.

For all the reasons mentioned above, we definitely recommend:

• Performance Pick: Nvidia RTX 3090 or RTX 3080
• Value Recommend: Nvidia RTX 3060 Ti and RTX 3070
• Budget Choice: Nvidia GTX Model

You’ll need a GPU with lots of CUDA Cores or Stream Processors for fast GPU Rendering and can add multiple GPUs for a near-linear increase of GPU Render Performance. Blender can take great advantage of multiple GPUs, delivering dramatic gains when a second card is added. 

Using more than one GPU will certainly speed up Cycles. In User preferences -> System -> Compute device, you can configure which Cuda devices to use. When rendering, each GPU will render one tile (following the settings on the performance tab). The more GPUs, the more tiles are rendered simultaneously, so dual GPUs will make a huge difference in Cycles by decreasing rendering time by almost one-half. 

In some cases of GPU rendering, mainly on previous versions of Blender 2.8, the whole system slowed down and became quite responsive. This issue has been fixed since version 2.8. Other than rendering, only one GPU will be used for many parallel tasks, both computing and rendering, which means that it does not even promptly process the displayed image on the interface of the operating system. Therefore, using multiple GPUs can resolve the slowdowns or lag problem, since the graphics processor will divide GPUs to render while the user can continue to use the PC for other things.

Render scaling of Blender & Cycles

In the chart above, it is clear to see that Cycles scales quite well when adding more GPUs. There’s no reason to stop at 4 GPUs out of fear of diminishing returns. Unless you’re typically rendering at samples less than 200, you’re better off with more than 4 video cards if your motherboard can handle it and you can afford the cards.

Second, scaling doesn’t need to be expensive. Let’s find out the solution we provide you in the next part.

If you use less memory/video memory, Blender may take a long time to complete rendering or it appears CUDA error: Out of memory. For massive scenes requiring a lot of memory, it is an incredible resource. There are two ways to solve this problem:

• Method 1: Smaller resolution textures

One way to reduce memory usage is by using smaller resolution textures. For example, 8k, 4k, 2k, and 1k image textures take up respectively 256MB, 64MB, 16MB and 4MB of memory.

• Method 2: Use NVlink

One crucial field for architectural visualization that is about to get some significant updates is Cycles when working with multiple GPUs. Today, you could easily use more than one GPU for a rendering in Cycles, which would split the load. Each GPU could handle part of the rendering, which cut in half your render times in many cases.

The main problem with that solution in Cycles, when using “old” interfaces like SLi (for NVIDIA), is that your GPUs would still act as two different cards. A new technology from NVIDIA called NVLink is different and can make multiple cards work like a single one. That is also valid for available memory.

To connect the cards, you need an additional piece of hardware called a bridge. For instance, if you want to go for an overkill setup, a dual GeForce RTX 3090 connected with the NVLink, the final amount of memory available for your scenes in Blender will be 48 GB.

iRender – Happy Rendering!

There are many potential problems when it comes to rendering. You must have often noticed that whenever you have a heavy rendering process, Blender suddenly crashes. But what are the reasons behind the sudden crashing in Blender and how to fix it?

Although it’s frustrating, the good news is that you should be able to fix this issue on your own easily after reading this article. I will divide it into two parts: First, iRender will point out three main reasons why your Blender keeps crashing again and again. In the second part, let’s discuss in detail how to fix them.

If your system does not have enough RAM to run Blender, Blender may crash. This is the main reason behind the crashes of the blender, often people install blender in low-end pc and blender also runs but as soon as they try to render, Blender will crash. Because a process like rendering requires more memory, if you use less memory/video memory, Blender will crash, or it may take a long time to complete rendering even if Blender does not crash.

This table has shown below how much RAM / VRAM be required to run Blender. For very complex and large scenes, you should follow the optimal system requirement, which requires at least 32 GB RAM and +12 GB VRAM.

If Blender is crashing despite your system having enough RAM, there may be a problem with your graphics card or driver. Blender can also crash in that case if the driver for your graphic card is not updated then first of all update the driver of your graphic card.

Even after that Blender is crashing then it means that your graphic card is not sufficient to make the blender run smoothly. Then if you want to know whether your graphic card will support it or not, I have given a list below, which you can see:

• NVIDIA: GeForce 400 and newer, Quadro Tesla GPU architecture and newer, including RTX-based cards, with NVIDIA drivers (list of all GeForce and Quadro GPUs)
• AMD: GCN 1st gen and newer. Since Blender 2.91, Terascale 2 architecture is fully deprecated, try using 2.90 (albeit not supported, it might still work) [list of all AMD GPUs]
• Intel: Haswell architecture and newer. [list of all Intel GPUs]
• macOS: Version 10.13 or newer for Intel processors on supported hardware. Version 11.0 for Arm-based processors (Apple Silicon).

As we all know, Microsoft Office declared Window 7 as dead officially from 14th January 2020, which means there will be no update for Window 7 in the future. So, Blender has also ended support for Windows 7, which may cause Blender to crash. 

We have learned what can cause Blender to crash, but what should we do to prevent Blender from crashing like this?

There are ways by which we can overcome this problem, below I have given some methods which will help you to fix this problem.

To prevent Blender from crashing, you need to free up some RAM on your system and also close unnecessary software running in the background so that the memory is available for Blender to function properly.

• You can go into Task Manager to see which programs are running in the background and how much RAM each program on the system is using.
• If you use Google chrome then you must know that google chrome consumes a lot of memory so make sure you do not use google chrome when heavy tasks are running in a blender.

Doing this will not only increase your processing speed but will also reduce the chances of Blender crashing.

You’ll need to keep your computer’s drivers up to date to prevent Blender from crashing. Doing so will not only increase the overall performance of your computer but will also reduce the chances of Blender crashing. You can take the help of your graphic card website to update the driver of the graphic card.

If your computer doesn’t have a dedicated GPU, there is every chance that Blender will crash. So, use a good graphics card (optimal: +12 GB VRAM) in your system. Below is a list of NVIDIA GPUs we updated with VRAM greater than 12 GB.

Let’s take a look at their rendering performance benchmark:

When it comes to looking at GPU specifications, pay attention to the number of compute-cores (CUDA or OpenCL, depending on what brand you buy) and the amount of VRAM. Blender is just as hungry for VRAM as it is normal RAM, and a GPU with ample VRAM is worth paying extra for if you’re interested in sculpting, high poly modeling, or GPU rendering.

For all the reasons mentioned above, we definitely recommend:

• Performance Pick: Nvidia RTX 3090 or RTX 3080
• Value Recommend: Nvidia RTX 3060 Ti and RTX 3070
• Budget Choice: Nvidia GTX Model

If you are still using an OS before Windows 7, such as Windows XP and Windows Vista, you can also switch your OS to Windows 8 or Windows 10. Also, there is no need to update the OS in Linux and macOS.
