Compiz Sees New Update Ahead Of The Holidays - But It's Mainly Bug Fixing

Filed under

Over a decade ago all the Linux desktop rage was over the likes of Compiz, Beryl, Compiz Fusion, and the like... Ah the memories. But to much surprise, Compiz saw a new release today. Compiz isn't the most exciting update, but the project is still alive.

Back in February marked the release of Compiz 0.9.14 as the first upstream release to the project in two years. Meanwhile today is a point release on top of that providing various fixes.

  • Linux 5.5 Staging Changes Land With New WiFi Driver To Improved exFAT Support

    Greg Kroah-Hartman mailed in the staging area changes today for the Linux 5.5 kernel and they have already been pulled into mainline.

    Among the staging activity work this cycle for Linux 5.5 includes:

    - The new WFX WiFi driver for Silicon Labs WF200 ASICs that are focused on low-power IoT hardware use-cases.

  • AMD's RadeonSI Driver Finally Enables OpenGL 4.6 But You Need To First Enable NIR

    The OpenGL 4.6 extension is nearly two and a half years old while finally the open-source Mesa OpenGL drivers are catching up to this latest OpenGL revision that offers Vulkan/SPIR-V interoperability and other additions.

    Last quarter's Mesa 19.2 release brought OpenGL 4.6 for core Mesa and Intel's i965/Iris drivers while tonight in Mesa 20.0-devel Git is support for RadeonSI! The AMD open-source OpenGL Linux driver can finally have GL 4.6!

  • AMDVLK 2019.Q4.3 Released With New Extensions + Navi 14 Support

    AMD's Vulkan driver team has today volleyed their third open-source "AMDVLK" code drop of the quarter. This AMDVLK 2019.Q4.3 driver comes with new extensions as well as Navi 14 enablement.

    Supported by AMDVLK 2019.Q4.3 is VK_EXT_pipeline_creation_feedback and VK_EXT_shader_demote_to_helper_invocation. EXT_pipeline_creation_feedback provides a feedback loop to the application/engine for use with pipeline caching as the principal benefit while the EXT_shader_demote_to_helper_invocation extension is for allowing behavior similar to Direct3D's HLSL discard instruction.

Intel Nehalem vs. Ice Lake Benchmarks - Including Clock + Power + Thermal Metrics

Filed under

As part of the exciting benchmark week and our ongoing tests of Intel Ice Lake on Linux, this next piece has been driven out of curiosity... While recently I posted new benchmark results of Intel Haswell to Ice Lake laptop performance, what about going further back like to the days of Nehalem? Here is that comparison of Core i7 Nehalem to Core i7 Ice Lake including power / performance-per-Watt data, thermal, and performance-per-MHz data too. Enjoy this fun comparison for how the Intel mobile performance on Ubuntu has evolved over the past decade.

The Nehalem part used is the ten-year-old Core i7 720QM "Clarksfield" processor. This CPU offers four cores / eight threads, 1.6GHz base frequency, 2.8GHz turbo frequency, a 6MB cache, and a 45 Watt TDP. Clarksfield is the mobile variants while Lynnfield made up the desktop side for the 45nm Nehalem microarchitecture.

300+ Benchmarks With AMD Threadripper 3960X vs. Intel Core i9 10980XE

Filed under

Complementing our launch-day Intel Core i9 10980XE and AMD Ryzen Threadripper 3960X/3970X Linux benchmarks, here is much more data now that we've had the additional time for carrying out more tests... For your viewing pleasure this US holiday week are more than 330 benchmarks carried out on both the Core i9 10980XE and Threadripper 3960X in the same configuration while running Ubuntu Linux.

For getting a more diverse idea of where the Core i9 10980XE Cascade Lake X and Ryzen Threadripper 3960X trade blows, I fired up a much broader set of benchmarks for comparison on these HEDT systems. Yes, the Ryzen 9 3950X is priced more comparatively to the i9-10980XE, but I was never sent a review sample of that processor so am using the 3960X for now -- if I get my hands on said processor, I'll certainly have a similar comparison on that front.

Graphics: Radeon, DRM in Wayland/Weston and X.Org's Modesetting Driver Gets Smarter

  • Radeon ROCm 2.10 Released With SUSE 15 SP1 Support, rocBLAS For Complex GEMM

    While AMD announced ROCm 3.0 earlier this month at SuperComputing 19 as the next major iteration to Radeon Open Compute, it looks like they aren't quite ready to ship it and instead released ROCm 2.10.

    ROCm 3.0 support was noted in their SC19 press release with having new HIP-clang improvements for better running CUDA codes on Radeon GPUs, expanded HPC programming model support with the likes of OpenMP / NAMD / LAMMPS, and new support for system/workload deployment tools like Kubernetes. ROCm 3.0 sounds like it should be a great release, thus surprising today they diverted to releasing ROCm 2.10.

  • Wayland's Weston 8.0 Bringing Direct-Display Extension, HDCP On DRM Back-End + More

    Simon Ser has stepped up again to manage the upcoming release of the Weston 8.0 Wayland reference compositor. No Wayland update itself is planned with nothing real to release at this point, but Weston 8.0 should arrive before the end of January.

    For making a January release target for Weston 8.0, Simon has laid out plans for the initial alpha release around 6 December, a beta release on 20 December, and the first release candidate on 17 January. If all goes well with Weston 8.0 RC1, the actual release could be on or around 24 January.

  • X.Org's Modesetting Driver Gets Smarter - Queries Mesa For Which GL Driver To Use

    There is a list of PCI ID driver mappings that has needed to be maintained for correlating graphics hardware to the respective DRI driver that should be loaded. That's been another maintenance burden and rather vintage, but now a modern solution has landed thanks to Intel's Ken Graunke. Since earlier this year has been the MESA_query_driver EGL extension for being able to query the name of the running 3D/OpenGL driver on the system. EGL_MESA_query_driver is now being used for dynamically querying the driver that was loaded by Mesa rather than having to duplicate the PCI ID driver mapping logic within X.Org Server.

    Besides the burden of having to maintain multiple graphics PCI ID mappings in 2019, the motivation for Graunke to get this change made is for Intel's transition to the "Iris" Gallium3D driver he has been leading. With Intel Gen12 / Tiger Lake graphics, only Iris is supported and starting with Mesa 20.0 they intend to default to this Gallium3D driver over the "i965" classic driver. Rather than having to work this logic into their mapping for the xorg-server, EGL_MESA_query_driver can simply leverage the logic from Mesa's driver loader.

  • Intel's SVT-AV1 0.7.5 Released With AVX2 + AVX-512 Optimizations

    Intel's crew maintaining the Scalable Video Technology open-source video encoders on Monday issued a new pre-release of SVT-AV1 in an effort to further speed-up AV1 video encoding on CPUs.

    With the SVT-AV1 0.7.5 pre-release, the encoder should run faster on modern Intel CPUs with adding additional AVX2 and AVX-512 optimizations. However, they did not elaborate on the precise performance benefits to be expected from this additional Advanced Vector Extensions tuning.

  • Mesa 20.0 Lands A Load/Store Vectorizer As Latest "ACO" Backend Improvement

    While the Radeon "ACO" compiler back-end performance is already looking very good in the speed department over the AMDGPU LLVM back-end for the Vulkan driver as shown in recent benchmarks, it's getting even better.

    On Monday another batch of ACO improvements landed. One of the big changes is the introduction of a load/store vectorizer that has been under review for four months before being approved for merging yesterday. This work by Rhys Perry is designed to "greatly reduce the number of memory operations."

Blender 2.81 Benchmarks On 19 NVIDIA Graphics Cards - RTX OptiX Rendering Performance Is Incredible

Filed under

Last week marked the release of Blender 2.81 with one of the shiny new features being the OptiX back-end for the Cycles engine to provide hardware-accelerated ray-tracing with NVIDIA RTX graphics processors. Long story short, OptiX is much faster for Blender than using NVIDIA's CUDA back-end -- which already was much faster than the OpenCL support within Blender. For your viewing pleasure today are benchmarks of 19 different graphics cards looking at the CUDA performance from Maxwell to Pascal to Turing and then for the RTX graphics cards also the OptiX performance.

OptiX is only supported with the NVIDIA RTX graphics cards but it offers a significant boost to the rendering performance. This NVIDIA-designed API for exploiting their RT cores introduced with Turing yields an impressive speed-up for Blender render times in common benchmark scenes. For more background information on OptiX with Blender 2.81 can be found via this blog post from the summer.

AMD Ryzen Threadripper 3970X / 3960X Linux Benchmarks

Filed under

After the embargo on the Intel Core i9 10980XE expired a few hours ago, now we are allowed to share the performance numbers on the new AMD Ryzen Threadripper 3960X and 3970X processors. These new Zen 2 HEDT CPUs pack a real performance punch, but do come in as more expensive than the i9-10980XE and there is one boot-stopping Linux bug to mention with a workaround... But besides that lone Linux support caveat, the Threadripper 3960X and Threadripper 3970X absolutely dominate in performance.

The Ryzen Threadripper 3960X is AMD's new $1399 USD processor that features 24 cores / 48 threads, 3.8GHz base frequency, and 4.5GHz boost frequency with an impressive 140MB cache. This isn't even the top-end Zen 2 HEDT and in core count and most other details already outpaces the Core i9 10980XE: the base clock is 800MHz higher than the 10980XE but the turbo/boost clock is 100MHz lower on the 3960X.

Intel Core i9 10980XE Linux Performance Benchmarks

Filed under

Intel today is rolling out the Core i9 10980XE as their new Cascade Lake X-Series processor that features 18 cores / 36 threads with a maximum turbo frequency of 4.6GHz and TBM 3.0 frequency of 4.8GHz. Following a last minute change, Intel moved up the embargo lift time of the Core i9 1980XE so here are the results we can share with you right now.

The Intel Core i9 10980XE Cascade Lake processor features the same core / thread count as the previous Core i9 9980XE and i9 7980XE but now with a 3.0GHz base frequency, 4.6GHz peak turbo frequency, 4.8GHz Turbo Boost Max 3.0 frequency, DDR4-2933 quad channel memory support rather than DDR4-2666, and the L1TF/Meltdown hardware mitigations in place. The cache size remains the same at 24.75MB and the processor having a 165 Watt TDP.
