Thinking of swapping Linux for Windows on your new Bay Trail NUC?

It would seem that installing Linux on your brand new Bay Trail powered NUC will cost you a bit of performance.  The testing Phoronix has performed on Intel NUC DN2820FYKH proves that it can handle running Linux without a hitch, however you will find that your overall graphical performance will dip a bit.  Using MESA 10.3 and both the current 3.13 kernel and the 3.15 development kernel Phoronix saw a small delta in performance between Ubuntu 14.04 and Win 8.1 ... until they hit the OpenGL performance.  As there is still no full OpenGL 4.0+ support there were tests that could not be run and even with the tests that could be there was a very large performance gap.  Do not let this worry you, as they point out in the article there is a dedicated team working on full compliance and you can expect updated results in the near future.

"A few days ago my benchmarking revealed Windows 8.1 is outperforming Ubuntu Linux with the latest Intel open-source graphics drivers on Haswell hardware. I have since conducted tests on the Celeron N2820 NUC, and sadly, the better OpenGL performance is found with Microsoft's operating system."

Intel's HD4600 versus AMD's 4600 on Linux ... with special guests

Subject: General Tech | November 20, 2013 - 05:00 PM |
Tagged: gaming, linux, mesa, open source

Phoronix is continuing to test the performance of open source Linux drivers on Source Engine games with this installation focusing on the performance of the Haswell i7-4770K.  They compare it to a number of RV770 based AMD GPUs as well as the newer HD 6450.  As you can see in the result the performance of the HD 6450 and HD 4550 are almost exactly the same and are the only two Radeons that do not leave the Intel's GPU in the dust.  If you have experience with the HD 4650 you have a very good idea as to how Intel's 4600 performs as the results are very similar.  Check out the full review here.

"Earlier this week I delivered some 13-way AMD open-source Linux GPU benchmarks when tested against Valve's Source Engine powered Team Fortress 2 and Counter-Strike: Source games. Now up for testing from the Steam Linux client on Ubuntu is the Intel open-source Mesa graphics driver performance with Core i7 "Haswell" graphics."

More Oland leaks, this time with open sauce goodness

Phoronix has good news for Linux users about the "RadeonSI" Gallium3D driver which AMD has slowly been developing for the HD 7000 series, MESA has announced the driver is being developed for the HD 8000 series.  The project commit is a candidate for MESA 9.1 and the Linux 3.9 kernel which could lead to some issues as most Linux flavours are using 3.8 or earlier but should bode well for the future.  This hopefully signals a greater commitment to OpenCL and other projects AMD has started but not managed to fully develop.  We also have quite a few PCI IDs from the commit statement, 0x6600, 0x6601, 0x6602, 0x6603, 0x6606, 0x6607, 0x6610, 0x6611, 0x6613, 0x6620, 0x6621, 0x6623, and 0x6631 are all listed.

"While AMD has yet to officially introduce their Radeon HD 8000 series, published today was the initial open-source Linux graphics driver support for handling the Radeon HD 8800 "Oland" graphics cards."

Interrupting Oktoberfest to run Mesa benchmarks under Linux

Phoronix are dedicated to testing out the current limitations of Linux and the graphics performance Sandy Bridge is capable of, so much so that they abandoned the joys of Oktoberfest to test the new implementation of hierarchical Z support for Intel's Mesa DRI driver.  Specifically they wanted to see the improvements made to the performance of the graphical portion of a Core i5 2520M.  The new implementation did well, with improvements across the board though more impressive in some tasks that others.  Read on to see what you can expect from the new Mesa driver.

"While there are still several days left of this year's Oktoberfest, to take a short break this morning from benchmarking the wonderful beer, food, and Bavarian females, here are benchmarks of the new Intel HiZ Linux support. Just a few days ago a new, nearly ready patch-set was published for implementing hierarchical Z support within Intel's Mesa DRI driver."
