Under GNOME and Ubuntu Unity, I haven't run into such problem. Namely, this bug and it seems to primarily hurt KDE users. However, other early Skylake Linux users have reported some problems. See the aforelinked article for more details.Īside from needing to set this kernel option seemingly until at least Linux 4.3, things on my end have been going well.
Even with the Linux 4.2 kernel users still need to set i915.preliminary_hw_support=1 in order to actually enable the i915 DRM driver to provide kernel mode-setting and hardware acceleration. Using the HD Graphics 530 on Linux on Ubuntu 15.04 and Fedora 22 has been going well over the past week, with one annoyingly silly exception: needing to pass a kernel argument to actually get graphics support. Hopefully Intel will be able to send over an i7-6700K soon for complementary Linux testing. Last week I ended up buying a i5-6600K after getting lucky in finding one in stock at a popular retailer and thus that's the sole Skylake processor being tested for today's article. Due to the limited availability, I didn't have a review sample for launch-day testing from Intel PR, but am still waiting.
The Core i5 6600K and Core i7 6600K launched two weeks ago but availability on these processors remain quite limited. We'll need to wait a while before seeing Skylake Iris Graphics with an eDRAM cache in socketed, desktop form. However, the HD Graphics 530 aren't meant to compete with Broadwell's Iris Pro 6200 Graphics as found on the Core i7 5775C socketed Broadwell processor. The HD Graphics 530 should end up being a nice upgrade over Haswell's HD Graphics 4600 found on the Core i7 4770K and 4790K. The HD Graphics 530 supports addressing up to 1.7GB of system memory, boasts 24 execution units, supports 4K 60Hz, three displays can be driven at once, and is capable of OpenGL 4.3 / DirectX 11.2 / DirectX 12_1. The Intel HD Graphics 530 on the Core i5 6600K have a base frequency of 350MHz and a maximum frequency of 1.15GHz. In this article is the first of these OpenGL benchmarks comparing the Core i5 6600K to other offerings from Intel and AMD. Given that Intel's Open-Source Technology Center has been working on open-source Linux graphics driver support for over a year for Skylake, I've been quite excited to see how the Linux performance compares for Haswell and Broadwell as well as AMD's APUs on Linux. Intel's Core i5 6600K and i7 6700K processors released earlier this month feature HD Graphics 530 as the first Skylake graphics processor.
