Phoronix: Early Benchmarks Of AMDGPU DRM-Next Code For Linux 4.10

For those curious if the AMDGPU DRM driver changes that are queued in DRM-Next for Linux 4.10 will bring any performance changes, here are some early numbers...

How are you achieving 66 FPS on Unigine Heaven. My average sustained rate is 50.2 with the new RX 480 8GB by XFX.

If I disable Tesselation with 4x anti-aliasing at 1920x1200 resolution my average sustained rate is 59.8. I'm running Debian Sid 4.8.7 Kernel.

Try running "phoronix-test-suite benchmark unigine-heaven" so you know for sure you are running it in same configuration, etc.

If running the PTS setup still shows a difference maybe CPU is a factor ? Looks like Michael is running an overclocked Xeon...

Its not overclocked, but yes a fast Skylake Xeon.

overclocked xeon? Are they shipping xeons with unlocked multipliers now?

OK, that's interesting... when I look up the 1280v5 around here it shows as a 3.4 GHz part, but the table in the article showed it running at 4.0 GHz.

3.7GHz base with 4.0GHz turbo - http://ark.intel.com/products/88171/...Cache-3_70-GHz

Base is 3.7, Turbo 4.0 GHz: http://ark.intel.com/products/88171/...0-GHz?q=1280v5

Mh, that's the higher clock it can go with the Intel boost thing. Intel non-unlocked processors have 3 100mhz steps in their multiplier. It ships by default at X but can go up as much as X+3 with the Intel boost thing that also disables other cores to compensate.

I don't know if the trick used in most boards (that tricks the CPU into keeping the max Intel boost frequency even in normal operation) works on xeons too, but It might be the case here.

Anyway, see here ark http://ark.intel.com/products/88171/...Cache-3_70-GHz
It shows 4 Ghz as "max turbo frequency", and 3.7 Ghz as standard frequency.
