RX580 Xeon E5 X79 Hardware Acceleration compatible?

PPCnostalgic · November 13, 2020

Good morning. I tried to browse about 3 days looking for a compatibility answer for my (old) rig. So can someone tell me if it's possible to enable HEVC + H265 hardware acceleration on this machine?

I'd like to hear an answer before i'll give up please. The system lists the card properly and Metal is supported.

MSI X79A-GD45 Xeon E5-2696v2 16Gb DDR3 Powercolor Red Dragon RX 580 8Gb (it's not the infamous SP 2048 version) Mac OS 10.14.6

Thank you!

HEVC=H.265 just like MPEG4=H.264.

Thank you Hervè. Using iMacPro1,1 SMBIOS the software lists HW acceleration but doesn't lists the video card (see attachment). Tried to encode a movie but despite I could enable HW acceleration the conversion was cpu only, the video card was idle.

Same issue with my HP Z400 + RX580 8gb, flashed as Pulse mac version...

Did you found a solution?

No, I switched back to Mac Pro 6,1 to be more accurate with my hardware. Honestly I think GPU hardware acceleration won't do more than CPU, a Xeon E5-2696vs with 12 cores.

BTW: I tried Opencore as well but nothing changed.
