This past weekend I posted an open-source Linux graphics driver comparison with an A10-7870K Godavari vs. i7-4790K Haswell vs. i7-5775C Broadwell. Beyond the already-published discrete AMD/NVIDIA GPU results to see how Intel's socketed Broadwell with Iris Pro 6200 Graphics stack up, there were also requests from readers for seeing some Haswell Iris results.
Intel has contributed Skylake SoC support to Coreboot.
This week I started testing Intel's new NUC5CPYH NUC as the first device with a Braswell SoC (not to be confused with Broadwell). The tests are progressing but the out-of-the-box experience hasn't been one of the best for Intel.
While I'm still working on my full Intel Core i7 5775C Linux review of this socketed Broadwell processor with Iris Pro Graphics 6200, and still working through some strange issues, I do have some Steam Linux gaming figures to share tonight for those interested in how Intel's latest-generation Iris Graphics are performing with the open-source Mesa driver stack.
It's been over a week now playing with the Intel Core i7 5775C on Linux and unfortunately problems persist even after buying another Intel Z97 motherboard.
If you have been interested in an Intel NUC as a 4-inch, low-power computer, the Braswell-based NUC5CPYH is finally in-stock and shipping at major Internet retailers.
Earlier today I wrote about how Intel has a lot of Linux graphics developers (likely 30~50) and is by far the company with the most active developers working on the open-source graphics stack. Here's some other numbers as part of the mailing list parsing for the other active companies, including NVIDIA, AMD, and Samsung.
Back in 2013 we heard Intel had 20~30 full-time developers on their Linux graphics driver team. Since then, they've only been hiring more developers. Based on email activity at least, here's a new number.
Now that I seem to have found a workaround for my Core i7 5775C Broadwell Linux issue that resulted in very frequent kernel panics, it's off to the benchmark races. Here are some preliminary Linux benchmark figures for this first socketed Intel Broadwell LGA-1150 desktop CPU with Iris 6200 graphics.
On Friday I mentioned I was running into stability issues on Linux with the Core i7 5775C, Intel's new socketed, high-end Broadwell processor with Iris 6200 graphics. The issue was quite perplexing, but I seem to have finally figured out a workaround for this problem that seems to be plaguing other early i7-5775C Linux users too.
While the Linux 4.2 kernel merge window isn't even over yet, Intel developers already have new code ready for testing that will be merged eventually for Linux 4.3.
A few days ago I received the Intel Core i7 5775C for Linux testing, one of the first Broadwell desktop/socketed chips featuring Iris 6200 graphics. In the days since, I've been trying to test it under Linux.
Canonical confirmed today that the Intel Compute Stick preloaded with Ubuntu will go on sale next week at $110.
Eduardo Lima Mitev of Igalia last week published a new vec4 back-end based on NIR for the Mesa i965 DRI driver. This work is part of implementing a NIR to Vec4 pass in order to allow using NIR for everything.
For those using perf for Linux profiling with performance counters, the Linux 4.2 kernel will bring many improvements to benefit Intel customers.
In an interesting move, Braswell support was added to Coreboot.
I'm told my Core i7-5775C "Broadwell" desktop CPU with Iris Pro 6200 graphics shipped out this morning. A.k.a. next week will be a ton of exciting open-source Linux performance tests on Phoronix of this quad-core Broadwell CPU with Intel's powerful Iris Graphics.
Initial support for Intel's Broxton has been added to their Mesa 3D driver.
In May the LLVM Clang compiler reached the state of complete OpenMP 3.1 support after the liberally licensed compiler saw its OpenMP support stagger for so long out-of-tree. Intel had been leading the recent efforts for getting OpenMP working in Clang and they've continued in working towards OpenMP 4.0 compliance.
Results have started appearing on OpenBenchmarking.org of the new Intel NUC5i7RYB that's powered by an Intel Core i7 "Broadwell" CPU.
Besides Phoronix celebrating its 11th birthday, last week Intel's SNA 2D acceleration architecture had its birthday and turned four years old. While the xf86-video-intel 3.0 DDX driver release is to make SNA the default for 2D acceleration over UXA, there's still no signs of this release happening.
Intel's upcoming Skylake and Broxton hardware will require some binary-only firmware blobs by the i915 DRM kernel graphics driver.
While Mesa 10.7 just recently entered development, the Git code is often benchmarked on Phoronix, and with not having delivered any Intel Broadwell Linux graphics tests in some time, here's the latest numbers as of this weekend.
The Intel Compute Stick packs a lot into a tiny package: 2GB of DDR3L memory, 32GB eMMC storage, Intel Atom Z3735F quad-core processor with Intel HD Graphics, Bluetooth 4.0, 802.11n WiFi, USB 2.0, and a microSD card slot... All into a 103 x 37 x 12 mm package, but how warm does it get under full load? Here's some numbers.
The Atom Z3735F is what powers Intel's Compute Stick. The Z373F has a Scenario Design Power of just 2.2 Watts while being a quad-core 64-bit processor with a clock speed of 1.33GHz and a burst frequency of 1.83GHz. This low-power Atom SoC also has Intel HD Graphics that work fine under Linux. In this article are some early test data from the Intel Compute Stick with Ubuntu Linux.
The Intel Compute Stick has begun shipping, a tiny device that plugs into any HDMI TV or monitor and turns it into a fully-functioning computer. This low-power PC ships with Windows 8.1 or Ubuntu 14.04 LTS, though at the moment the Windows version is first to market with the Ubuntu Compute Stick not widely shipping until June. I have an Intel Compute Stick at Phoronix for testing.
Yesterday I ran some fresh tests of Intel Ivy Bridge on the latest Mesa Git code to see if the performance has changed much recently for the slightly-older generation of Intel HD Graphics. Today I've done some similar tests in kernel-space with the Linux 4.1 kernel.
Most often these days when running Intel Linux graphics tests at Phoronix it's with Haswell, Broadwell, or Bay Trail hardware. However, in being curious if there's any performance improvements for slightly older hardware with Mesa 10.6 or Mesa 10.7-devel Git, I've run some fresh Ivy Bridge numbers.
Some Video Acceleration API updates are coming down the pipe.
David Airlie has pulled Intel's latest batch of changes into DRM-Next that they've been queuing up for merging into the Linux 4.2 kernel.
