Windows 10 vs. Ubuntu 16.04 Graphics Performance With Radeon Software, AMDGPU-PRO, AMDGPU+RadeonSI

Thanks for the article. Very interesting for Nvidia fan boy. Prrhaps next my card can be ATI. Though i am not changing my gtx780ti any time soon... No money.

Why?

There're three popular C/C++ compilers — GCC, Clang, and — the only closed compiler — the MS one. Last time I compared GCC produced code faster than Clang. And GCC has really many optimizations. I can't compare with MS one, but I actually very doubt it produces assembly better than GCC.

I don't think that GCC is anywhere near Intel or MS compilers, at least for Intel CPUs. Also we should add power governors and the Gallium threading model. I get a lot of overhead even on Gallium Nine.

Just realised that these tests are done in 4K resolution...

It's good to see that the Vulkan performance is about the same for Linux and Windows. If Polaris is indeed competitive with Nvidia cards, I'll likely buy a RX 480.

It probably *wont* be.

Current indications are a bit better performance than the R9 390 but for $199 (that is quite a lot of bang for your buck though)

So, all those people wanting to upgrade to something that can support VR can, without breaking the bank.

Thanks

Looks like only Nvidia drivers are having the problem of Linux Vulkan performing slower than Windows vulkan.

Similar to Michael's results on my AMD R9 290 as well Linux Vulkan performs the same as Windows Vulkan in Talos Principle.

A really nice comparison. I'm really happy with the results because I see a great improvement. There are still performance issues with some badly ported games but on the other hand Metro Last Light and Bioshock Infinite performed even better than on Windows. So I would say that in total the linux drivers are going to get on par with the Windows drivers.
I'm really looking forward to get my RX 480: http://wccftech.com/amd-rx-480-1500m...ool-voltage-2/

Well the GPUs they are releasing as Polaris are actually designed to compete with Nvidia 1060 and below. Which Nvidia will probably release soon after. Mainstream market.
AMD's competition to the GTX 1070,1080 and above comes via their Vega architecture which will take a few more months to release. High end market.

AMD's competition for the GTX 1070, 1080 and above comes in the form of the Vega architecture (formerly Greenland). Will take a few more months to come out. High end market.

Some benchmarks show it performing better than a GTX 970 and in some cases even a 980.
It doesn't need to beat a 980 or a 1070, but it should at least perform comparable to Nvidia cards of the same price.
At the bare minimum it needs to beat a 960. (On Linux+Vulkan, OpenGL may be a lost cause.)
I'll have to wait until reviewers get their hands on a RX 480, to see what it is capable off.

FYI I will have launch day RX 480 Linux review.
