X5000 - GfxBench2D score

Hi,

I see, that yesterday somebody posted new GfxBench2D score to hdrlaborg.nz page.

Fantastic 13,030.65 points! X5000 with Polaris10 card!
For the first time is X5000 faster then X1000.

I am glad to see, that here is driver speed improvent.
Thanks to all involved, especially Hans.

I think we see noticable differences in that score.
1) RadeonRX driver version 2.10. Iirc, the latest public release is 2.8

2) It's a Gigabyte RX580 4 GB. Maybe this means that the RX580 is now supported for 3D and/or video acceleration as well?

3) When I compare the score with my own X5000/RX570 score, the difference seems mostly caused by improved memcopy performance: WritePixelArray Memory copy ~525MB/s -> ~1100MB/s ; ReadPixelArray ~25MB/s -> ~1000MB/s. Is this due to DMA/GART support?

The second best score is with a RX570. Although it's a different RX570, it's better for comparing with my setup. RadeonRX driver is 2.11 (i have 2.8) and pcigraphis.card is 54.1 (i have 53.18).

Somehow, the performance of everything except memcopy and "random score" is worse. This can be explained by a difference in GPU clock speed. The second one can be explained by the huge memcopy improvement as it is part of the random test.
The memcopy performance improvement is similar as for the RX580 card above: WritePixelArray Memory copy ~525MB/s -> ~1050MB/s ; ReadPixelArray ~25MB/s -> ~950MB/s.
The bottomline score improved from 8248 to 9171.

RX580 is already supported with 3D/Video acceleration since the last the public update.

@SinanSam460

Ok. Didn't know that. I thought that only the video decoding issues were solved for the RX550/560/570.

So maybe 2.8 isn't the latest driver as well. Time to run updater.

Yeah, the latest public one is 2.8. All after till 2.11 in beta for now.

Quote:

They supported by 3d and video acceleration for some time already (and that support in public already too).

Quote:

That is because just a few weeks ago Frederik add DMA acceleration support to the graphics.library, meaning that WritePixelArray() and ReadPixelArray() are now DMA accelerated (the same as it was for x1000 before, and that was the reason why x1000 results were superior before).

But that is not driver's DMA, but just for graphics.library. So once Hans will deal with everything in terms of DMA in drivers, things should be faster in terms of pure MemCopy functions from ram to VRAM and from VRAM to ram.

If you mean that one : https://mail.hdrlab.org.nz/benchmark/g ... 2d/OS/AmigaOS/Result/2346

Then it's my yesterday's upload.

For myself, i can't explain why i have in some parts that slower speed in comparison with another upload where one scored 13.000.000.

But I also have in ragemem test from sysmon strange 50% decrease in video bus reading speed, which I can't explain for the moment.

And my card is Saphire RadeonRX 560 2GB

Quote:

As far as I know, for now (since some time) every RX card which works in 2D works in 3D and have video acceleration working. And if i remember right that all already in public.

Quote:

2.8 is the last one, but maybe you also need to update everything else, like warp3dnova to the latest public one, etc.

I have run some benchmarks with different driver versions and gfx cards and put the results in a table (thanks to gnumeric) and exported as html : https://sd-1.archive-host.com/membres/ ... 124662650/GfxBench2d.html

funny that the transfer from VRAM to RAM is much better with an older version of the RadeonHD (v1.21)

R9-270 is much better than RX550 but the consumption is 150W vs 50W...
I would guess that the RX580 is currently the best card for the X-5000 (but the consumption is 185W) !

I also run the starbox 3D demo and here RX550 is better :
StarBox Benchmark 1.0
RadeonHD R9-270
Resolution: 1920 * 1080
Fullscreen
FPS: 307.70

Radeon RX 550
Resolution: 1920 * 1080
Fullscreen
FPS: 388.99

Power=High
Resolution: 1920 * 1080
Fullscreen
FPS: 392.03

another fun fact is that under Win10, furmark 3D benchmark gave 2696 points (45fps) for R9-270 vs 1022 points (17fps) for RX550
