VideoProc, free this weekWhat app is that Hardware Info ?
Polaris supported GPUs start with RX-460 and go up to RX-590.So all Polaris and higher cards are the RX cards correct?

When I run: sudo kextcache -update-volume /
I get this: Warning: /AppleInternal/Library/Extensions: No such file or directory
UPDATE: After the third time restarting and doing the process from step 1, it went through without the error. It works now. Thanks!
Just to confirm, not really news here, put my 7950 in for boot screen support moving to 10.14.5 final (ended up had to move my boot-args to make things work ...) no hardware decode/encode is gained by this on flashed 7950
Thanks for the report.
So, confirmed 7950 cannot get H264 hardware acceleration via this method, right? (7950 is the ONLY card in the cMP)
If yes, then I will update the OP Q&A section.

How about the HD 7970 ? Possible with your method ?
( I have VideoProc to check )
R9 280X uses the same EFI as Sapphire HD 7950 Mac Edition and it's essentially the same GPU, why would be different?h9827690
Thanks, I thought so too.
How about the R9 280X ?
Think a little, what EFI did you used to flash your R9 280X?tsialex
Are you sure ? I thought that the 7950 = R9 280 7970 = R9 280X
Codenamed Tahiti, the Radeon HD 7900 series was announced on December 22, 2011. Products include the Radeon 7970 GHz Edition, Radeon HD 7970 and Radeon HD 7950.[18] The Radeon HD 7970 features 2048 usable stream cores,[A] whereas the Radeon HD 7950 has 1792 usable stream cores, as 256 out of the 2048 cores are disabled during product binning which detects defective areas of a chip. The cards are the first products to take advantage of AMD's new "Graphics Core Next" compute architecture. Both cards are equipped with 3 GB GDDR5 memory and manufactured on TSMC's 28 nm process. The Tahiti GPU is also used in the Radeon HD 7870 XT, released November 19, 2012. In this case one quarter of the stream processors are disabled, giving 1536 usable cores. Additionally, the memory interface is downgraded from 384-bit to 256-bit, along with a memory size reduction from 3 GB to 2 GB.
MIKX, it's the SAME chip, binned. The EFI used is the Sapphire HD 7950 Mac Edition.Just to make a point . . .
I do not have an R9 280X.
I have a 7970 devid=6798
./makerom.sh --efifile=7970mac.efi --romfile=efiromheader_7970.rom --originalrom=cardname.rom --devid=6798
=================================
7950 devid=679a
devid=679a
./makerom.sh --efifile=7950mac.efi --romfile=efiromheader_7950.rom --originalrom=cardname.rom --devid=679a
Both cards use the same Tahiti but different device IDs.
Just wanted to be clear on whether the 7970 could use hardware acceleration.
Yes, I read your line 41 and showed exactly why won't work. The only older than Polaris AMD GPUs that have the same UVD as Polaris is R9-380/R9-Fury/R9-Nano, this ones should be tested.tsialex
I DID read your post ! I have read the whole thread. I was just checking.
Did you read the last line in #41
Enough.
It is also pointless for an retro gpu like that one... i don’t belice that’s much faster than the MacPro CPU‘s
I wonder if that hit the RX580 limit. Or due to something else.
Hi Hendrik94,
Can you test if the Radeon VII can play this video smoothly?
http://jell.yfish.us/media/jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv
That 400Mbps is the just the overall bitrate. But IINA shows more bitrate actually allocated to the 1st half of the video, the peak is over 500Mbps. And the RX580 seems struggle to play that.

This is with AMD GPU video decoding enabled:
Mine plays it smoothly, start to finish with zero dropped frames. RX580 Pulse. VLC. When skipping around, it takes 2-3 seconds to play. I see one CPU core maxed out while it's resuming play at a new point. Bottleneck is either a single thread or RAM read speed.
