  • Another Navi 14 Workstation GPU Patch Turns Up For "Pro-XLM"

    Yesterday we reported on two Navi 14 device IDs being added for "workstation SKUs" while today a third has appeared.

    Yesterday were 0x7341 and 0x7347 being added for the AMDGPU driver as Navi 14 parts and the patch message acknowledging they are for workstation parts. To date AMD has not announced any Navi-based workstation products. The Navi 14 GPU is widely believed to be a low-end GPU akin to a Polaris successor and competing with NVIDIA's GeForce GTX 1600 Turing series. This is while AMD continues to evolve Vega for workstation/compute purposes too.

  • Intel's Gallium3D Driver Gains Optimization For Helping With Java OpenGL Performance

    In our recent Mesa 19.2 benchmarks of Intel's old and new (Gallium3D) OpenGL Linux drivers one of the rare areas where the new "Iris" driver performed behind the classic driver was with "j2dbench" that stresses the Java OpenGL pipeline. At the time it was unknown why the new driver was performing subpar for this Java graphics test, but now at least there's one optimization so far in addressing that shortcoming.

  • AMD Linux Improvements Pending Around FreeSync Low Frame Rate Compensation

    Sadly too late for the upcoming Linux 5.4 merge window, but for Linux 5.5 it looks like there will be a FreeSync improvement around low-frame-rate compensation.

    Sent out this morning were 25 new AMDGPU DC patches. Of these "display core" patches, there are various fixes and continued work on the Adaptive Backlight Management (ABM) but exciting us the most is the FreeSync work.

  • The Intel SVT-VP9 Performance Boost Across 10 Intel/AMD Systems

    As a follow-up from this weekend's article about Intel's SVT-VP9 video encoder running much faster on AVX2 CPUs from both Intel and AMD, here are the results now before/after for ten different systems with this open-source CPU-based VP9 video encoder.

AMD EPYC 7642 Benchmarks: The Rome 48 Core CPU That Easily Takes On Intel's Xeon Platinum 8280

Since the AMD EPYC 7002 series "Rome" launch at the beginning of August, it's been known how AMD's top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor. Complementing our recent EPYC 7302 and EPYC 7402 benchmarks, today we are focused on the EPYC 7642 as the Rome 48-core / 96-thread processor. This 48 core processor has a 2.3GHz base clock and 3.3GHz boost clock while having 256MB of L3 cache, eight DDR4-3200 memory channels, 128 PCIe 4.0 lanes, and other features in common with the EPYC 7742 and other Rome processors. The EPYC 7642 carries a 50MHz base clock speed advantage over the 64 core EPYC 7742 but a 100MHz lower boost clock speed as the principal differences aside from the core/thread count. Both of these CPUs carry a 225 Watt TDP. Read more

Plasma 5.16.90 (Plasma 5.17 Beta) Available for Testing

Are you using Kubuntu 19.04 Disco Dingo, our current Stable release? Or are you already running our development builds of the upcoming 19.10 Eoan Ermine? We currently have Plasma 5.16.90 (Plasma 5.17 Beta) available in our Beta PPA for Kubuntu 19.04 and 19.10. This is a Beta Plasma release, so testers should be aware that bugs and issues may exist.

Raspberry Pi 4 getting hot? A closer look

I hope that will all arrive in time for me to try it out over the weekend, so I can pass along some more information about temperatures, and about what pieces fit together in which cases, if any. Finally, the Raspberry Pi Foundation says that they are working on several software and firmware changes that should help bring the temperature of the Pi 4 down. Hopefully those will be released soon - but even if they are, I don't expect that they will improve the situation by more than 5 degrees or so, and given how hot the Pi 4 runs, that is not enough to eliminate the need for the kind of hardware measures I am looking at now.

Top Open Source Video Players for Linux

You can watch Hulu, Prime Video and/or Netflix on Linux. You can also download videos from YouTube and watch them later or if you are in a country where you cannot get Netflix and other streaming services, you may have to rely on torrent services like Popcorn Time in Linux. Watching movies/TV series or other video contents on computers is not an ‘ancient tradition’ yet. Usually, you go with the default video player that comes baked in with your Linux distribution (that could be anything). You won’t have an issue utilizing the default player – however, if you specifically want more open-source video player choices (or alternatives to the default one), you should keep reading. Read more
