NVIDIA or AMD for Blender?
In this guide
For a new Blender PC focused on Cycles rendering, we’d start with NVIDIA RTX. Cycles is Blender’s rendering engine that simulates light to create realistic images.
AMD is worth considering when a specific card gives you more useful memory or a better price—and still renders fast enough for your work.
This guide covers desktop GPUs on Windows and Linux. Already have a card that handles your projects comfortably? Keep it until you have a clear reason to upgrade.
Why we start with NVIDIA
RTX cards can use OptiX, an option in Blender that uses NVIDIA’s dedicated hardware to calculate lighting. NVIDIA also supports some specialized workflows: custom shader code (OSL) can run on the graphics card through OptiX, with limitations, and OctaneRender on PC requires NVIDIA.
Those features may not matter to every project, but they’re good reasons to put RTX on your shortlist for a new rendering workstation. Blender’s GPU support, OSL support, and Octane’s requirements explain the specifics.
When AMD makes sense
Choose AMD when the particular card is the better deal for your projects. That might mean more memory within your budget, or an attractive price for rendering performance you’re happy with.
Supported AMD cards can also render with Cycles. Before buying, check your exact GPU, Blender version, and operating system—especially for older Radeon cards and features such as denoising, which removes grain from renders. Blender lists the compatibility requirements.
Fast rendering doesn’t automatically mean smoother editing. If you mostly model, move around scenes, or use Blender’s Eevee renderer, look for tests of those tasks.
Get enough memory, then compare speed
VRAM is the memory on the graphics card. For a new general-purpose Blender PC, 16 GB is our starting recommendation, not a minimum requirement.
| Your projects | Memory to consider |
|---|---|
| Smaller scenes you’ve tested | 8–12 GB may be enough. |
| A mix of everyday Blender work | Start by looking at 16 GB. |
| Large environments, heavy textures, or volumes | Consider 24–32 GB or more. |
Your actual scenes should decide. Render a demanding frame at final settings, check peak GPU memory use, and leave room for the project to grow. Falling back to system RAM can slow rendering, so don’t count on it as extra VRAM. Blender’s memory FAQ covers the limits.
Once memory is covered, compare render times and prices. If a review renders the same scene with the same quality settings on two cards, the one that finishes sooner is faster for that scene.
Some comparisons show a Blender Benchmark score instead of minutes. A benchmark is a standard speed test: each card gets the same sample scenes to render in Cycles. A higher score means faster rendering in that test. Compare results from the same Blender version and operating system. The score won’t tell you exactly how long your own project will take. Blender explains how the test works.
Three checks before you buy
- Your tools work. Check the renderer, add-ons, and any custom shaders you use.
- The card fits your PC and budget. Check case space, power, and cooling. Include upgrade and delivery costs, and review the warranty.
- Your own project passes the test. During the return period, render a heavy frame and check the image, memory use, speed, and stability.
