Four Years After Launch, AMD Kaveri Sees Huge Performance Boost On Linux

[Holograph]

oh wow ... what the ... so nobody bothered to fix this for a few years ...

Yeah, this is WTF. Probably affects power efficiency a lot too, which is unacceptable. Shame.

I remember some time ago Intel APUs had surpassed Kavery on OpenGL tests. I'm curious to see if the situation remain the same. Especially that i7 5775C with the Iris GPU.

That was just the Iris Pro parts though (eg 5775C), wasn't it ?

Now that dc has been made the default will we be making amdgpu the default kernel driver for gcn 1.1 GPUs?
It's about time.

Actually DC was temporarily made NOT the default for amdgpu on GCN 1.1 due to startup problems with VGA and LVDS displays, so making amdgpu the default will need to wait until the VGA/LVDS issues are figured out and DC can be re-enabled as default.

At this point, Kaveri-based A10s (maybe even the A8s) would likely outperform Intel's lineup, except the Iris Pro. I'm not sure about the A12.

Typos:

given the rendr back-end change,

For those curious about the Vulkan versus OpenGL performanceo n the A10-7870K

Would this change improve rendering using OpenCL?

Are there any news on UVD support on GCN 1.0? That is the thing I am missing the most sadly with Linux I have to choose from hardware video acceleration and Vulkan support.

There's no UVD for x265 or VP anyway, so pick Vulkan
