Graphics/Benchmarks

The Samsung 980 PRO PCIe 4.0 NVMe solid-state drives are now available from Internet retailers. For those wondering how these SSDs compare with EXT4 under Linux against other PCIe 4.0/3.0 drives, here are a variety of benchmarks.

While Samsung hasn't sent out NVMe SSDs for Linux testing at Phoronix, we continue purchasing the new models due to their high performance state and needing some additional drives for various systems in the lab. When the Samsung 980 PRO reached retail channels this month I picked up the Samsung 980 PRO 500GB and 1TB drives and ran a series of benchmarks on them prior to commissioning.

  • Intel Core i7 1165G7 Tiger Lake vs. AMD Ryzen 7 PRO 4750U Linux Performance

    For the Intel Tiger Lake Linux benchmarking thus far with the Core i7 1165G7 on the Dell XPS 13 9310 it's primarily been compared against the Ryzen 5 4500U and Ryzen 7 4700U on the AMD side since those are the only Renoir units within my possession. But a Phoronix reader recently provided me with remote access to his Lenovo ThinkPad X13 with Ryzen 7 PRO 4750U (8 cores / 16 threads) for seeing how the Tiger Lake performance compares against that higher-end SKU.

    Phoronix reader Tomas kindly provided SSH access to his ThinkPad X13 with Ryzen 7 PRO 4750U and 16GB of RAM. The Ryzen 7 PRO 4750U is quite close to the Ryzen 7 4800U with 8 cores / 16 threads but graphics capabilities in line with the 4700U. He's been quite happy with the ThinkPad X13 as a replacement to the Dell XPS 13 for business usage and has been running it with Ubuntu 18.04 LTS on the Linux 5.8 kernel.

  • Mike Blumenkrantz: Catching Up

    A rare Saturday post because I spent so much time this week intending to blog and then somehow not getting around to it. Let’s get to the status updates, and then I’m going to dive into the more interesting of the things I worked on over the past few days.

    Zink has just hit another big milestone that I’ve just invented: as of now, my branch is passing 97% of piglit tests up through GL 4.6 and ES 3.2, and it’s a huge improvement from earlier in the week when I was only at around 92%. That’s just over 1000 failure cases remaining out of ~41,000 tests. For perspective, a table.

  • AMD 'Big Navi' 3DMark Firestrike results shared by HW testing firm

    The Linux specialists over at Phoronix have noticed that the AMD Linux driver has been tweaked to add support for a new graphics card dubbed the "navi10 blockchain SKU". It comments that the only visible difference in support for this card vs existing Navi 1X support, from the driver perspective, is that the patches disable the Display Core Next (DCN) and Video Core Next (VCN) support - basically creating a 'headless' Navi 1X graphics card.

    Cryprocurrency is showing signs of a resurgence in popularity and values, and some are worried that the latest and greatest GPUs from both Nvidia and AMD will be plucked from retailers even faster if they are viable mining platforms. It has been reported that AMD is trying to make sure retailers follow certain distribution practices with its upcoming Radeon RX 6000 series products, to make sure they are distributed to gamers and enthusiasts rather than scalpers and such like. An initiative like creating appealing crypto-specific Navi 1X products might help everyday consumers get their hands on a new Navi 2X graphics card too.

  • NVIDIA Ships Vulkan Driver Beta With Fragment Shading Rate Control - Phoronix

    This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus.

    NVIDIA on Tuesday released the 455.26.02 Linux driver (and 457.00 version for Windows) that adds this fragment shading rate extension.

  • Intel Begins Adding Alder Lake Graphics Support To Their Linux Driver - Phoronix

    Intel has begun adding support for Alderlake-S to their open-source Linux kernel graphics driver.

    An initial set of 18 patches amounting to just around 300 lines of new kernel code was sent out today for beginning the hardware enablement work on Alderlake-S from the graphics side.

    Yes, it's only a few hundred lines of new driver code due to Alder Lake leveraging the existing Gen12/Tigerlake support. The Alder Lake driver patches similarly re-use some of the same workarounds and changes as set for the 14nm Rocket Lake processors with Gen12 graphics coming out in Q1.

  • AMD Linux Driver Preparing For A Navi "Blockchain" Graphics Card - Phoronix

    While all eyes are on the AMD Radeon RX 6000 "Big Navi" graphics cards set to be announced next week, it also looks like AMD is preparing for a Navi 1x "Blockchain" graphics card offering given the latest work in their open-source Linux driver.

    Patches posted today provide support for a new Navi graphics card referred to as the "navi10 blockchain SKU."

    The Navi 10 part has a device ID of 0x731E. From the AMDGPU Linux kernel driver perspective, the only difference from the existing Navi 10 GPU support is these patches disable the Display Core Next (DCN) and Video Core Next (VCN) support with this new SKU not having any display support.

Auto-Suspend Inactive X11 Applications To Reduce CPU And Battery Usage With XSuspender

Graphics/Benchmarks
Software

XSuspender is a tool to suspend X11 applications when they are inactive. Its purpose is to reduce CPU usage, which in turn reduces the battery usage, and decreases the CPU temperature and fan noise.

The tool uses SIGSTOP, which prevents the process from obtaining further CPU time, or a custom shell script that you can specify, to suspend an application after its window loses focus. When the window regains focus, it's immediately resumed so you can continue from where you left off.

Windows 10 vs. Ubuntu 20.10 Performance With Intel Tiger Lake, AMD Renoir

Filed under
Graphics/Benchmarks

Stemming from our initial Intel Core i7 1165G7 "Tiger Lake" benchmarks on the Dell XPS 13 9310 last week and then also discovering better single-threaded performance on Ubuntu 20.10, one of the pressing questions was whether this is expected performance on Linux or if it's coming up short of Microsoft Windows for this first tier-one notebook to market with Intel Tiger Lake. So following those earlier tests I proceeded to do a Windows 10 Pro with all available updates comparison on Ubuntu 20.10 with the i7-1165G7. For added context, the same software stack and tests were repeated on an AMD Ryzen "Renoir" notebook.

Today's article answers the question of Intel Tiger Lake performance on if it's coming up short against Windows and where any outliers are between the Windows and Linux support for these latest-generation Intel mobile processors. Plus with the AMD Ryzen 5 4500U "Renoir" Lenovo Flex 15 performance added in there it also helps address whether any of the tests/benchmarks may be favoring one operating system over the other and ultimately seeing how the Windows vs. Linux raw performance is for these autumn 2020 notebooks.

  • Nouveau + LLVMpipe Drivers Enable OpenCL Image Support - Phoronix

    The interesting work continues pouring in for Mesa 20.3 as the Q4'2020 feature release to this open-source graphics stack... The latest excitement is on the "Clover" front for Gallium3D OpenCL. 

    The LLVMpipe software back-end and Nouveau NVC0 Gallium3D drivers now are advertising OpenCL image support! This is important for making use of OpenCL acceleration with programs like Darktable and LuxCore, among many other imaging type programs supporting OpenCL.

  • Intel OpenGL/Vulkan Linux Drivers Strike Another Optimization For Tiger Lake - Phoronix

    It was just on Monday that Intel's talented open-source developers merged a hefty Tiger Lake graphics optimization into the Mesa 20.3 code that for some games/software can be around ~11% faster thanks to greater caching. Just a day later another optimization has arrived for helping these latest-generation Intel graphics. 

    Merged on Tuesday was a change to benefit Intel's Iris Gallium3D (OpenGL) and ANV Vulkan drivers for making use of the HDC data cache for uniform buffer object (UBO) pulls on Gen12+ hardware, namely Tiger Lake at this point.

  • New NVIDIA Vulkan Beta Driver 455.26.02 is out

    Need the latest bleeding-edge Linux drivers from NVIDIA? There's a new release out of the Vulkan Beta Driver.

    [...]

    Reminder: This special Vulkan beta driver is where all the shiny new stuff goes in before making its way into the stable release for everyone. Really, it's mostly aimed at developers and serious enthusiasts. Unless you need what's in them, it's generally best to use the stable drivers.

    The newest stable versions of the main NVIDIA driver for Linux are at 450.80.02 released on September 30 from their "long lived" series or 455.28 released on October 7 from their "short lived" series. Confused?

  • Arch Linux - News: nvidia 455.28 is incompatible with linux >= 5.9

    nvidia is currently partially incompatible with linux >= 5.9 [1] [2]. While graphics should work fine, CUDA, OpenCL, and likely other features are broken. Users who've already upgraded and need those features are advised to switch to the linux-lts kernel for the time being until a fix for nvidia is available.

  • Radeon Linux Driver Seeing "MALL" Feature For Big Navi - Phoronix

    The AMDGPU open-source Linux kernel graphics driver continues seeing work on next-generation GPU support around the forthcoming "Big Navi" GPUs.

    Building off the Sienna Cichlid support that has come together and made its debut for Linux 5.9, and has further improvements for the now in-development Linux 5.10 kernel, new patches are now surfacing as material that will eventually make its way into Linux 5.11 for release as stable in early 2021.

    One of these late feature additions for Sienna Cichlid is the "MALL" display feature. MALL in this context is the Memory Access at Last Level. This Memory Access At Last Level is a DCN 3.0 feature for enhancing power savings with the screen contents coming from the "MALL" when certain conditions are met. At least at this point the support is only enabled for Sienna Cichlid and not other variants like Navy Flounder.

  • NIR-To-TGSI Support Added To Mesa 20.3 - Phoronix

    Mesa 20.3 has merged a long work-in-progress patch series providing support for going from the modern NIR intermediate representation to TGSI as the conventional Gallium3D IR.

    The NIR-To-TGSI translation layer has been in the works for most of the year with hopes of using that to eventually kill the Mesa state tracker GLSL-to-TGSI code that is quite large and crusty. While RadeonSI, Iris, and the other larger Gallium3D drivers are making use of NIR for a while now, this NIR-to-TGSI path can help other Gallium3D drivers like Softpipe that still rely on TGSI. If getting rid of the GLSL-to-TGSI path, GLSL shaders would ultimately go through NIR and then translated to TGSI.

  • Intel Lands A Hefty Tiger Lake Graphics Optimization - Phoronix

    From my Tiger Lake testing so far with the Core i7 1165G7, the "Gen12" Xe Graphics have been quite compelling with a very nice upgrade over Gen11 and especially obvious win over the very common still Gen9 graphics. With Mesa 20.3, another measurable performance is on the way for the Intel Vulkan driver with Tiger Lake.

    For Tiger Lake (and theoretically Rocket Lake as well), a new and significant optimization landed today in Mesa 20.3-devel. The optimization applies for Intel Gen12 graphics except for discrete/DG1 graphics.

  • Vulkan Specification Version 1.2.158 Brings Two New Extensions

    Version 1.2.158 of the Vulkan specification introduces VK_KHR_fragment_shading_rate that lets developers change the rate at which fragments are shaded on a per-region, per-primitive or per-draw basis and VK_KHR_shader_terminate_invocation which, together with the previously introduced VK_EXT_shader_demote_to_helper_invocation extension, lets developers do a much more specific OpKill.

  • Open-Source RADV Vulkan Driver Is Seeing Work To Allow Building It On Windows - Phoronix

    An independent party has slowly begun merging patches into mainline Mesa for allowing the open-source Radeon Vulkan driver "RADV" to build on Microsoft Windows.

    AMD is not behind this effort nor Valve but has been worked on in recent months for making Mesa's Radeon Vulkan driver code compatible with Windows. James Park of a little known "Lag Free Games" has been behind this initiative to bringing it to Windows and seemingly only explaining in private to upstream Mesa developers his motivations for doing so.

    RADV as a reminder is the Mesa Radeon Vulkan driver started out by David Airlie of Red Hat and Bas Nieuwenhuizen of Google in the time while waiting for AMD to open-source their Vulkan driver. AMD ultimately provided "AMDVLK" as their official open-source Vulkan driver derived from their internal Vulkan driver sources and built against the AMDGPU LLVM compiler back-end.
