thank you kaneske and Aluveitie

Very interesting thread

I am concentrating on how to read temperature and utilisation device on OSX with 6900Xt

Found some way with Fakesmc and radeon monitor kext, but this way misses many important data as volt or RPM fan

may I ask how do you check low frequency and voltage on AMD?

TheWachowski my was not a criticism to the choice of that kind of benchmark.

Only in the past it was proven it does not reflect well "power and speed" real life and it was possible also to cheat to have better performance, I do not remember but I think downloadfritz explain here or in other forum as data hub could interfere in this benchmark

About FPS difference, it is weird because I thought a 3950x (but also your CPU @5Ghz) could do better with that NVME (I use a sabrent rockets 4.0)

I have also better result with s sabrent rocket 3.0 (better than Aluveitie speed) but I do not know if he uses PBO and in that condition... in my case it is only enabled on bios

with my rig in signature, I think is not so valuable GeekBench test

I have had also a 3090 reference and in some real test in Davinci Resolve I had a 10% better performance with my reference 6900 xt (cuda vs Metal)

I do not understand some benchmarks and results on the net...maybe Nvidia pay better the reviewers

A common error is about SIP (it should be disabled before you do all installation)

This AMD ix is valid for all CC version and the only problem unsolved for now is with stabilisation and Morph Cut effects in premiere

I do not know others guide

Maybe you can ask to the guide and method creator (@tomnic)

Cddyby a new way to patch it:

link to new adobe fixes

youtube video

HAI it is a Gengik84 app

you can find here:

link

you have to register on it and a minimal number of post (1 or 2) to download all the app there

Gordon-1979 sorry for English but my German could be also worst.

in below schema you can see how to build patch for different system.

XX is your cores number, as you did well 06 for a 6 cores, 08 for a 8 cores, 0c for a 12 cores, 10 for a 16 cores, 20 for a 32 cores

It is possible to not use this patch if you compile Opencore shaneee PR which include those patches inside a quirk:

ProvideCurrentCpuInfo

attention only PR Opencore edition has those patches included. Official release No

Sorry to be a bit off topic

Beta 4 on 3970x threadripper!

Beta 2 on Threadripper 39070x

Thank @algrey

5fps is about 12.5 % faster...in same situation could be useful

then I agree in normal condition a 6900xt is not a best BFTB..

walter77 when have had your same motherboard there was a weird behaviour with Davinci Resolve preference

different result with different approach to select gpu and metal

Zitat von walter77

@fabiosun

3x RX 6900 XT, 64 Nodes: 65 fps

3x RX 6900 XT, 6 Nodes THN: 35 fps

2x RX 6900 XT, 64 Nodes: 55 fps max

2x RX 6900 XT, 6 Nodes THN: 29 fps

1x RX 6900 XT, 64 Nodes: 31 fps max

1x RX 6900 XT, 6 Nodes THN: 27 fps

So that's not linear but i think for other Davinci related reasons.

Another nice test is a speed change to 25% with Retime Process set to Optical Flow and Motion Estimation set to Speed Warp.

If you have some project to test for retime process set to optical flow I will like to tst it

Thank you

sorry walter77 I have posted original project with is lock to 24fps..you can pu there 250 in project settings

You should test 6 nodes and 66 nodes I have read better now (it seems only two gpu are used for playback..but maybe I am wrong on this

I have this results with only a GPU with my trx40 in signature

6 nodes

30/32 fps

66 nodes

40/42 fps

On intel platform. you can try also to force Metal and test then to force in auto and test again

In the past on intel platform Davinci had a weird behaviour for this two settings

Thank you a lot for your test

walter77 thank you

here for the project:

https://we.tl/t-yK8RhSdxYE

here if you want to se how to use and test:

if your 3 GPU scale well in your system it should be a top beast in Davinci Resolve.

My single 6900 XT in Metal performs better than my previous RTX 3090 Fe in CUDA

walter77 very curious to see a Davinci Resolve Candle benchmarkreuslt with your 3 gpu!

AMD users have to wait to try to start to find these new missing patches:

different problem here

now I need of pikera boot args to login with AMD 6900xt Gpu and MacPro7.1

Middle mouse button wheel in Safari browser does not work

in Chrome is ok.....

It is disabled

Yes Aluveitie

Also viceversa

works:
