Any decoding improvements on Premiere Pro V.22 for AMD systems???

Just saw the new Premiere update (v.22) and improved decoding for 10bit 422 H264 and HEVC footage. Sounds great. But will this not improve playback performance of H264 and HEVC footage on an AMD system?

 

I have:

 

AMD 5950x CPU

AMD 6800XT GPU

64GB ram

etc.

 

(I also have a boxed 3080 card if you think that'll be better than the 6800xt...but went with the 6800xt because of puget system's test results for multicam which I do often. We only work with Sony footage (H264 and HEVC...mostly 10bit stuff)

it should work.. the 6800xt has gpu acceleration. im pretty sure that the 6800xt would perform better in premiere though. 

 

i dont see why the update wouldn't be improved for the 6800xt.

The reason I was asking...the update says: 

 

New hardware-accelerated decoding for 10-bit 4:2:2 HEVC files provides improved playback and smoother editing with supported hardware, including M1 Macs and Windows Intel machines.

 

and

 

New hardware-accelerated decoding for 10-bit 4:2:2 H.264 provides an improved editing experience on M1 Macs. 

 

NOTHING about AMD Systems???

They didn't mention NVIDIA cards either.. 

 

I think in that message, they are referring to CPUs. The systems they are referring to (M1 Macs and Windows Intel machines) are most common, especially since they are laptops. I would still think that they made it better for AMD machines in the update, but I searched on Google and nothing came up about improved performance for AMD systems. 

 

Yeah, so I really don't know. You won't get off any better with a 3080 most likely since the 6800xt is better for editing in general.

The problem with that is that Adobe Premiere Pro simply does not perform well in OpenCL in Windows. Adobe continues to optimize its CUDA renderer while it has neglected its OpenCL renderer for several years now. AMD GPUs do not support CUDA at all in Windows; they support only OpenCL in that environment.

 

And this lackadaisical support for OpenCL is majorly resonsible for the relatively poor live playback performance in Windows systems with discrete AMD GPUs compared to even those with cheap Nvidia GPUs.

 

With that said, the 10-bit 422 H.264/HEVC decoding support applies only to integrated graphics processors (M1 for Mac and Intel UHD/Iris Graphics for Windows and Mac) at this time.

I think 'most' of the AMD GPUs in use are on Macs now, and Apple of course "requested" that all participating partner vendors "deprecate" OpenCL. Which was a very heavy request. To be polite.

 

So I guess that it hasn't seemed that useful for the Adobe developers to work on AMD cards using OpenCL, expecting most of them to run Metal.

 

Tough for many users though, that's for sure.
