Davinci on Apple M1 Max vs 5950X 3090 - 2x faster !!!

Most tools in Fusion are limited by the CPU way before the GPU. There are exceptions of course.

Fusion was built for render farms and hasn't really transitioned fully to the more modern paradigm of CPUs with a high core count.

Not all compositing tools can benefit form GPU-type calculations, those that can are mostly too non-intensive for a GPU i.e. any GPU renders them in a blink, but they need to wait for the the tools that can be CPU only to render.

If you use Optical flow node, you can pretty much saturate the GPU...Also most 3D nodes use GPU 3D engine extensively, including Render3D...however, it's not safe if you do network rendering on a series of machines that have a mix of NVidia and AMD between them since they can render OpenGL in a slightly different manner so differences can occur between frames.

I'm pretty sad that Fusion gets such a bashing when in reality it uses GPU as much as possible, look at other compositing software - same thing or worse...at least you can do multiple frames and tool branching render at once on all the cores that you have....

RTX3090 is twice as fast as M1 graphics... Which is also very troubling for the Nvidia - their flagship GPU being just 2x faster than a small SoC.
I am being a little bit evil.

It's not small SoC. Another thread is - in which type of calculations is faster? Coding / decoding? OK, keep in mind that most comparison are being done in ProRes which is used by Mac (not on PC). In various type of calculations the difference will be different. Would also nice to see comparisons with newest 4000 series - both new decoding module NVENC and typical processing based on CUDA cores.

Back in April I got a Studio Max partly because there was no way to get an upgrade GPU for my PC and if I could it was similar price. I was having difficulty on my PC to play back 6K files from my GH6 which the Studio Max play easily because of the hardware codec not in the 1080Ti on the PC. However playback of Fusion scrolling titles is not too different to my old PC with 1080Ti, in some case the PC is faster, so when it comes to pure GPU power without hardware assist, I am not too sure it cuts it compared to new GPU on PC. Maybe it's my old 12 core Threadripper that is faster !! Yes PC uses a lot more power. Comparing to my old PC the Studio Max is nice, silent and edits my GH6/GH5S files easily still with occasional stutter in multicam though with audio sync going off. I think the big advantage is the hardware assists for modern codecs. If you do not want to use these for encoding etc then I feel a PC will be faster and maybe cheaper.

Hi,

Have you ever had audio files fail to appear when recording 5.7k HVEC on your GH6?

If so, any solutions?

I have at 2018 MacBookPro with a wx9100 external graphics card. Does the Studio do better at this, since I think it has dedicated HVEC decoders?

While I don’t have a GH6, my M1 laptop doesn’t show such issues with HEVC in UHD out of our Sony A7IV.

No, I have not had any problems with audio not appearing. Of course it always records 4 channels that need to be dealt with even if there is only one that is being used. Yes Studio Max has dedicated decoders and encoders the main reason I got it. The Studio Max plays all the files just fine in multicam. If there are filters etc then sometimes I can tell the audio is going out of sync. A stop playback and restart is all that is needed to get things going again. Not a problem that bothers me. This in multicam so a lot of decode and encode going on. Most of my projects are 3 camera multicam. GH6 5.7K 60P, GH5S C4K 60P and AX100 HD 60P. Project is usually edited in either UHD or HD multicam. Studio Max has no problems playing this for realtime editing in multicam. My PC just stalls on these projects. I am thinking of getting an iPad M2 12.9" to use as preview monitor and may use to color Airplay to my Sony HDR TV so that I actually see on a real TV.

Thanks for your reply. Maybe I need to find someone with a Studio and bring my files to them to check on them. May have just been some setting I screwed up. Easy enough to do with the rather complicated menu system of the gh6.

The processor I have is 8th generation so it should have some built-in capacity for HEVC files if apple is accessing them in Big Sur, which is what I'm currently running for various reasons. The search continues.

Intel 8th gen is too old for 10-bit HEVC with 4:2:2 subsampling. You need 11th gen or later, or an Apple M1 or later.
