Early Open-Source Linux Benchmarks Of The AMD Radeon RX 470

Those drivers for AMD is starting to look decent compared to nVidia

Actually the performance of AMD drivers is really great. The games where nVidia has huge leads are all wrapped games like Bioshock, tomb raider, witcher 2, and the rest.

Polaris10 is the successor for Tonga. Strange not to see r9 285 in the tests.

Haven't had time to test it yet, will be in tomorrow's article.

Michael, I've mentioned that on a previous thread, but could you please start writing conclusions to your article?

Why no Vulkan tests? For Doom I've heard AMD to be much faster.

As mentioned many times in the article, this initial testing was done with the open-source driver stack.... AMD hasn't released an open-source driver stack... The recent Radeon Vulkan stack started by David Airlie isn't yet useful yet either...... But as mentioned in the article, when I do AMDGPU-PRO tests, there will be Dota 2 numbers.

Hmm, sadly the power efficiency of the hot-clocked 470s isn't really an improvement over the RX480 (which is the 8GB model which already has worse power efficiency than the 4GB models)..

I'll be curious to see if someone does performance/power numbers of a stock clocked 470 at some point just to see if the 470 can actually be more energy efficient than the 480.

Michael : Do the new overclocking bits in Linux 4.8 allow underclocking cards driven by amdgpu? If so, it might be interesting to check out the difference in power efficiency between the overclocked speed and stock clocks when you have some of that mythical free time.

Nope, from all I've tried, the OverDrive support doesn't allow negative percentages for downclocking... The only option would be to like disable PowerPlay or keep it forced into a lower power state. Haven't seen if there's a power state close to that of the reference speeds.

Although to be fair I guess if the card can run the game at >60 fps at 4K maximum quality then that's a fairly good result in itself.
