AMD Tonga & Fiji Open-Source Performance Boosted By PowerPlay Patches

[dungeon]

they support 285,380 and not 390x ?? why? what about 390x customers?

390X as GCN 1.1 gen is supported by radeon driver.

You need the following mesa and kernel patches for optimal performance with Fiji:

While some question at times why I still run OpenArena frequently in graphics tests... Even though this is an old OpenGL 2 game, it managed to uncover an open issue with the Radeon R9 Fury not being able to run this game without crashing.

I don't ask that , as you see Carmack's code seems still the best indicator of stability

Fury is really slow, maybe the HBM is not clocked correctly.

The next one comes out tomorrow.

it would be nice to include new fiji tests with http://www.phoronix.com/forums/forum...630#post834630

Yeah and hopefully he wouldn't get this with those patches:

Alex, it seems common prob those random corruptions with Fiji even on Windows? I guess documentation bug somewhere, but seems related.

Here you see that in windows r9 285 is a way more faster than 750ti.

In Metro Last Light benchmark i can have same fps with amd x 860k and nvidia 750ti with nvidia 358 driver. So amd oss driver stack needs some improvment to get max result off the amd graphics.

This is opensource driver, R9 285 with Catalyst runs 40% faster that Metro LL

Please dunno compare eggs with balls

By comparing xonotic with 285 at 2560x1660, amdgpu is faster than fglrx!!!!!!!
This is really impressive!!! Thx Michael!!!!

Don't be so happy about, because AMD might fix it It is enough for them to enable one MCCaps1 profile without any further optimizations and it would go over it

Xonotic is one of those ultimate capped to singlethread games, where even DRI3 helps much

That triangle test is strange to me. Why is Fiiji almost 2/3rds slower than Tonga? Is it an optimization issue ?
