    Phoronix: Kaby Lake HD Graphics 630 Appear To Be Coming Up Short On Linux

    One would think the graphics of a Core i5 7600K "Kaby Lake" processor would be faster than the Core i5 6600K "Skylake" or even a Core i5 6500, but that's not always the case with the current state of the Linux driver support for the newest-generation Intel hardware.

    I'm not surprised. Been using Linux on my t460s with Skylake since kernel 4.4 and one thing is certain: 4.9 is the first kernel release that has made me feel free Skylake is 100% good to go. Ever since upgrading to 4.9, my experience has been rock solid. None of the little glitches and ocassional drm related crashes from before. I was even able to remove "i915.enable_rc6=0" from my kernel command line and reclaim three extra hours worth of battery life.

    Given the lackluster reviews for Kaby Lake even on the Windows side, I'll be sticking with my t460s until at least early next year. Lenovo's upcoming models don't offer enough in the way of other improvements to get me to pull the trigger on an upgrade this year. But given that my t460s is now working so damn well, if it's not broken, why fix it?

      Maybe it is slower , even on Windows i think watched some gaming scenes slower on 7600K than on 6600K with dGPU also... who knows what that video was something random can't find it now on GTAV or something...

      Smells like bios issues, but who knows.

        Is there a place where I can map together "Core i5 7600K" and "Kaby Lake", "Core i5 6600K" and "Skylake", etc?

          Is this surprising, considering the last xf86-video-intel driver predates Kaby Lake?

            No, because all tests were done with xf86-video-modesetting and the DDX driver anyhow doesn't have that much impact on 3D perf.

              Huh? Can you clarify what you are saying?

                If you're looking for 3D in xf86-video-intel, you're totally wrong. Mesa, libdrm, the kernel ans alikes are better places. Another culprit for your message would be to determine the last driver. Since there is no 3.0 release for some years, we should all know intel stopped supporting linux at all....

                  Wikipedia can help you, although I don't think there is a page listing all CPU names with a microarchitecture name:
                  - https://en.wikipedia.org/wiki/List_o...oarchitectures
                  - https://en.wikipedia.org/wiki/List_o...icroprocessors
                  - https://en.wikipedia.org/wiki/List_o...icroprocessors
                  - https://en.wikipedia.org/wiki/Skylak...roarchitecture)
                  - https://en.wikipedia.org/wiki/Kaby_Lake
                  and more...

                    Thanks totoz, already the first link helps me to know that Sandy Bridge came before Haswell, it helps to understand the chronology in some articles here.

                    Now there's also the gen6, gen7, gen8 that I'll need to decipher. This marketing naming maze can be quite redundant some time.

                    Edit:
                    This wikipedia article seems to list the intel gpu generations: https://en.wikipedia.org/wiki/List_o...ocessing_units
                    But now there is still the link between the marketing name ("Sandy Bridge", etc) and the generations.

                    It seems they don't understand how small do we care about these names, we just want to have a scale from low-end to high-end. Having to choose between 10 CPU/APU just for the same generation, and having 3 or 4 generations on the market at the same time is pure intellectual masturbation (if you ask me). I thought marketing guys would have understood, since a decade of Apple rising and PC desktop falling, that consumers want a bit of simplicity in this world (and I'm not talking about going all Apple, which is as ludicrous but in the other side of the spectrum), but merely be reasonable with the offer.
