# Is it possible to use DaVinci Resolve without any GPU AT ALL?

I have some plan to get servers that are powered by Intel Atom C2750: Intel Atom® Processor C2750.

... and they don't have any GPU at all.

Is it possible to render at this CPU? Render time isn't the problem. Just ... is it even possible?

• It is free. Download it, install it, test it. – Rafael Sep 29 '19 at 17:52
• @Rafael - it's difficult to download hardware. – AJ Henderson Dec 15 '20 at 16:19
• @AJHenderson LOOOOOL HAHAHAHAHA but you could downloadmoreram.com though – Rinaldo Jonathan Dec 23 '20 at 6:47

From DaVinci Resolve System Requirements, in the “Resolve Minimum System Requirements FAQ” part:

... your GPU will determine if Resolve will run at all on your system ...

So yes, you need a GPU, and even not just any GPU.

From the same source:

It’s ALL About The GPU

Your GPU is everything! It is more important than your CPU or system RAM (both of which should be up to the task too).

DaVinci Resolve offloads intensive image processing to the GPU. It also employs YRGB 32-bit floating point processing for exceptional color precision.

and

GPU Memory

Of course GPU cores matter, but GPU memory matters more when looking at minimum requirements .

512MB – Forget about it.

1GB   – You’ll be okay with basic HD ProRes work, checking RAW files but avoid
noise reduction and optical flow.
1.5GB  – Approaching the absolute minimum to use Resolve with some level of complexity in HD.
Noise reduction and optical flow will still be problematic.
2GB  – A comfortable HD experience, limited 4K work.
4GB  – Minimum for comfortable 4K work.
6GB  – You can tackle pretty much everything a project is likely to require.
8GB+ – You can actually tackle everything any project is likely to require.


Bottom line, if you’re looking at a new system on a budget and you’re working mostly in HD, I’d recommend an absolute minimum of 2GB GPU memory, really 4GB is a more realistic minimum. Performance also depends on the resolution of your media, the resolution of your timeline and the codecs of the media you are using.

• I wish I could render with just CPU, not editing on it. – Rinaldo Jonathan Sep 29 '19 at 13:15
• I'm afraid I don't understand you - rendering what? Something edited in other computer but not yet rendered? – MarianD Sep 29 '19 at 13:32
• correct. I like to have whole project synced to google drive file stream, to render somewhere else. As of today, I usually render on alibaba cloud, but way too expensive because of the gpu. If only I could use cpu only ... – Rinaldo Jonathan Sep 30 '19 at 12:16
• I'm not totally sure, so I tell you only my opinion. Rendering itself is still such complex, computational-intensive process, so I'm not able to realize it without GPU. Even if it would be possible, it would be too slow even for you — I suppose 100+ times slower than with GPU (i.e. 1 month without GPU instead of 7 hours with GPU). – MarianD Sep 30 '19 at 12:46
• When i open dxdiag on a windows machine i see 3 different valiues for the graphic card memory: 1-total approx memory, 2-VRAM, 3-Shared memory, which one are you refering to in your post ? – Xsmael Sep 3 '20 at 9:58

Even if you could tweak, say, your machine's BIOS or even Resolve's own settings to somehow not use any GPU at all, I really don't recommend doing it. Resolve is built around GPU power to render stuff.

• This may be true, but every time I render, cpu is always 100% while both intel and nvidia gtx didnt even reach 30%. – Rinaldo Jonathan Sep 30 '19 at 12:17

I've tried running DaVinci Resolve 17 on my ThinkPad X1C with Mesa Intel UHD Graphics 620, and it complained about the GPU configuration. After unchecking the checkboxes to use some "auto" GPU, it complained about having to set some media location. After setting that, it exited silently.

Turned out that choosing a media location made it exit silently in the first place, so I can't see what happens if I uncheck those checkboxes with a media location set, but I suspect it won't run anyway.

This 2018 forum post says that "most modern AMD, Intel and NVIDIA GPUs that support OpenCL 1.2 or CUDA 3.0 compute capability will operate with Resolve" and that "INTEL(R) HD GRAPHICS 3000 does support OPENCL 1.2".
