[Trisquel-users] Skylake Desktop Graphics Test Results
So we're doing some basic testing of skylake now... read post below for details.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Our initial results are interesting. It appears that there is 3D acceleration with Skylake on the desktop system we've built using only 100% free software, but it's performance is less than that of older Intel chips. I'll update this when I know more.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Can you try it with Parabola or the JXself's kernel repo? Maybe upgrading X will be the reason of the bad performance.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
We tried it with jxself's kernel on Trisquel 7. I don't know if Parabola GNU/Linux-libre has a newer version of X, but it might be something worth trying. Bob however thinks it probably won't matter- or make a difference in the performance anyway.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Note that Skylake's ix-6xxxK's graphics are worse than the ix-5xxxC graphics (the "C" was used in Broadwell for a reason). (Of course this doesn't go for haswell, etc) Skylake laptops will probably get better graphics than Broadwell, so yeah that'll be interesting.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Maybe the Xorg driver for Intel could matter a bit, also, MESA GL functions.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Hi! Chris, Do you know anything more about Skylake in Trisquel? Do you recommend buying a processor Skylake or with Haswell? Thanks!
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Parabola has newer kernels and a newer version of X.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Just in case you don't know, Trisquel has also newer X available. https://trisquel.info/en/wiki/installing-latest-backported-kernel-and-xserver
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
For laptops Compare both processors. I rather buy a laptop that uses a Broadwell chip that is equal or even better than Haswell chip for its ability to stay cool,battery life, etc etc. Yes, I prefer a desktop for gaming anytime, but a lot of games are playable that are using broadwell chips. compare both specs http://ark.intel.com/compare/80343,85212 reviews http://www.pcworld.com/article/2940489/the-truth-about-intels-broadwell-vs-haswell-cpu.html I hope you make your decision based on your needs and purpose.

davidnotcoulthard Skylake is the codename for the Intel® processor microarchitecture that is the successor to the Broadwell microarchitecture. http://ark.intel.com/products/codename/37572/Skylake Intel's New Skylake Processors: What You Need To Know http://gizmodo.com/intels-new-skylake-processors-what-you-need-to-know-1728020921 I still love my old Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155 -
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
For desktop computer, you can get much better GPU that any Intel. And today you can buy Nvidia Kepler cheaply. Nouveau with Kepler works like with blob (in performance)(you must to switch pstate manually with command).
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Do all Kepler cards really work now?
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
This is still experimental. When I took gtx650 and later gtx770, I was not able to reclock with pstate because it is a experimental feature. With help of genius "karolherbs" from nouveau irc channel, we could reclock both GPU (with same fix/patch), karolherbs patched "nouveau.ko" and I compiled it with jxself's kernel 4.3. He patched PCIe 3.0 support too, but no difference for me, my board supports 3.0 but not my CPU (i7-2600). Here nothing more to fix with Kepler GPUs, cuz it is already runs near blob, not 100%, but almost. I tested with much libre games. And sorry, I tested too with some steam games, like CS:GO (and more non 2d games, just for test the performance). The bad thing is, that you must powering on pstates with commands, and it is still impossible step from lowest pstate directly to the highest, but yes, you can step from highest to lowest one.
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
Doesn't change what I said though (Broadwell was so late that we got Haswell-E instead and by the time Broadwell could be launched Skylake was looming which probably had to do with Intel sticking the Iris 6200 into it which is better than Skylake's desktop iGPU)...
Re: [Trisquel-users] Skylake Desktop Graphics Test Results
The integrated Broadwell CPUs in small desktops are fine. This is not to say all small systems that have integrated Broadwell CPUs are OK. There are I'm sure systems with problems out there unrelated to the CPU with many of them... That said I'd stay away from Skylake and Broadwell socketed desktop CPUs for now. There are problems with both. Broadwell has stability issues and bugs in the CPUs. Skylake isn't supported yet at least without patches, etc. Hopefully Intel figures out the issues with the Broadwell socketed desktop CPUs sooner than later. It might be better to skip Broadwell and go straight to Skylake here although as it's not yet supported its hard to tell. There might be some issues with Skylake from a libre stand point. I think we concluded it's not as bad as we anticipated though. Either there wasn't any non-free blobs or they weren't critical or something like that. Though I don't remember if it resulted in the loss of power management support or not. I think power management still worked. Part of this might be the result of the blobs being loaded by the BIOS and the blobs that are loaded by the OS are basically optional updates (they could be critical too in theory).
