AMD Radeon Graphics Performance On The Linux 3.18 Kernel

[bridgman]

The R9 290 continues to be disappointing compared to the mid end AMD cards. Too bad, at least I hope it is more stable.

It's ~40% faster on GPU-limited benchmarks, which roughly matches the difference in shader hardware, so that seems about right.

The slowest card tested is ~HD4870 class and average is more like ~2x that, so it's not unexpected that the less demanding apps are going to be CPU-limited.

There's still a lot of churn in the DRM drivers.... e.g. just from Linux 3.17 - http://www.phoronix.com/scan.php?pag...linux317&num=1

It's not click bait, it lets people know if/what's changed wrt to graphics performance with Linux 3.18.

Yeah, I've got no problems with this article. There have been a bunch of performance improvements for radeon SI in the past few kernels.

Wasn't there an issue with the Hawaii cards where they would randomly lose their reclocking ability and get very slow? I was wondering if this kernel fixed that, but it doesn't show up in the 3.17 results here either.

Ghee what a surprise.
The kernel actually doesn't do very much.
Performance is mainly determined by mesa.

Other then oibaf ppa should consider to use llvm3.6 git to better show radeonsi improvments in latest 2+1 that is actually ~3 months now... i am mostly satisfied

Read it as: we don't see what happened with llvm in last 3 months here

+1 (stupid character limit)

Nothing worse than a "It didn't change" review.
But good to do it anyway, thanks Michael!
