AMD Ryzen 9 3900X vs. Intel Core i9 9900K Performance In 400+ Benchmarks

Filed under
Graphics/Benchmarks

Given the recent AMD "ABBA" Ryzen 3000 boost fix, the upcoming release of Ubuntu 19.10 powered by Linux 5.3, here is a fresh round of AMD Ryzen 9 3900X vs. Intel Core i9 9900K benchmarks in a side-by-side matchup . It's just not any comparison but our largest i9-9900K vs. 3900X comparison ever: 112 gaming benchmarks and 321 system/CPU benchmarks carried out for our most extensive look yet at how these ~$500 CPUs are competing in this fierce race.

This round of Core i9 9900K vs. Ryzen 9 3900X benchmarking was done while both systems were running the latest daily release of Ubuntu 19.10 powered by the Linux 5.3 kernel, which itself brought some nice performance-related work over previous kernels. Ubuntu 19.10 is also now running GNOME 3.34.0 that can make a difference for some gaming benchmarks while its default driver stack is currently on Mesa 19.1.6.

The Core i9 9900K was running with the ASUS PRIME Z390-A motherboard and the Ryzen 9 3900X with the ROG CROSHAIR VIII HERO WiFi motherboard, both boards using their very latest public BIOS releases as of testing. Both systems were tested with the same GSKILL 2 x 8GB DDR4-3600 memory, 280GB Intel Optane 900p NVMe SSD, and Radeon RX Vega 64 graphics card. The RX Vega 64 was used over the Radeon RX 5700 series due to Ubuntu 19.10's older Mesa build not having Navi support and the Navi support in general still maturing and recommended for use with Mesa 19.3-devel, so with this not being a graphics card comparison anyhow, the RX Vega 64 was the safer and more accurate card to use for this round of testing.

  • Panfrost Gallium3D Driver Focusing On Bettering The Arm Midgard Support

    While there hasn't been too much to write on it in recent weeks, the Panfrost Gallium3D driver within Mesa for Arm Midgard/Bifrost graphics continues chugging along. The latest work on it is switching over to a new scheduler for Midgard.

    If using a Midgard GPU, a.k.a. the Mali T604 through T880, that seems to be the recent focus of lead Panfrost developer Alyssa Rosenzweig.

  • GCC Is Potentially Months From Seeing Radeon OpenMP 4.5 / OpenACC 2.6 GPU Offloading

    At last month's GNU Tools Cauldron was an update on the Radeon GCN back-end state for the GCC compiler, which is likely to see more code land around year's end.

    Merged for GCC 9 was the initial Radeon GCN back-end for targeting AMD GPUs from the GNU Compilers Collection as an alternative to their long-standing AMDGPU LLVM compiler support. With GCC 9 the Radeon GCN support was limited, but for next year's GCC 10 support it should be in better shape. They have a path forward to make it quite capable, but it might not all land in time for GCC 10.

GeForce RTX SUPER Linux Compute Performance - 18 GPU NVIDIA OpenCL Comparison

Filed under
Graphics/Benchmarks

Last week we began our belated NVIDIA GeForce RTX SUPER benchmarking by looking at the RTX 2060 / 2070 / 2080 SUPER Linux gaming performance in a 26-way graphics card comparison. For those more interested in the RTX SUPER graphics cards for their OpenCL compute performance potential, these benchmarks today are for you.

This article provides a look at the compute performance potential for these newest NVIDIA graphics cards. Given the workloads and AMD still not providing any Radeon Open Compute (ROCm) support for their newest Navi graphics cards, this comparison is just looking at the NVIDIA compute potential between the Maxwell / Pascal / Turing line-ups. You can treat this as a reference comparison and for those curious about the generational power efficiency / performance-per-Watt and other metrics.

  • QEMU's Assortment Of Virtual VGA/GPU Options & What To Pick For Desktop Virtualization

    The virtual GPU/display landscape particularly for having accelerated guest graphics was once non-existent and then suffering for the open-source Linux virtualization stack around QEMU, but that is no longer the case. There are options these days to rival the GPU/display offerings of VirtualBox and VMware albeit to newcomers may not be so clear.

    Longtime QEMU/virtualization developer Gerd Hoffmann has written a blog post outlining the VGA/display devices for QEMU and the recommended options. The options he covers at length include the standard VGA device, Bochs display device, VirtIO VGA, VirtIO GPU, Vhost-user VirtIO GPU, QXL VGA, QXL, Cirrua VGA, ATI VGA, and RAMFB.

  • Intel's Inaugural Release Of OpenVKL Ties Into Their Promising oneAPI Rendering Toolkit

    While announced some months ago, today in-step with the OSPray 2.0 Alpha ray-tracing release is the inaugural development release of the Open Volume Kernel Library (OpenVKL).

    Intel's Open Volume Kernel Library is a set of volume computation kernels optimized for AVX/AVX2/AVX-512 and leverages their SPMD Program Compiler. OpenVKL ties into Intel's other open-source render components like OSPray for what will form their oneAPI rendering tool-kit. We're now in Q4 and that is when the beta release of Intel's oneAPI is expected.

  • LuxCoreRender 2.2 Released With Intel Open Image Denoise Yields Faster Render Times

    LuxCoreRender, the open-source physically based renderer for execution on CPUs as well as OpenCL accelerators / GPUs, is out with version 2.2 and now integrates Intel's open-source Open Image Denoise.

    LuxCoreRender already made use of Intel's Embree library (as happened to be covered this morning with benchmark results in The Xeon vs. EPYC Performance With Intel's oneAPI Embree & OSPray Render Projects) while now they have also pulled in Intel's Open Image Denoise.

  • Unofficial Radeon ROCm Packages Re-Enable APU Support

    Over a year ago the AMD APU support in the Radeon Open Compute (ROCm) stack was quietly removed and has yet to be re-enabled in the upstream ROCm packages. But should you be wanting to use ROCm for their compute APIs or OpenCL on APUs, unofficial Ubuntu packages are now available to provide this capability.

    Engineering firm Bruhnpace AB has resorted to providing their own ROCm packages for Ubuntu 18.04 with AMD APU support enabled to make up for AMD's lack of official packages handling APUs in the different ROCm libraries. The repository doesn't provide its own rocm-dkms package but rather recommends users run the latest upstream kernels for the AMDKFD kernel driver support.

  • Phoronix Test Suite 9.0.1 Available Along With Several New/Updated Test Profiles

    As a minor update following last month's Phoronix Test Suite 9.0 release, version 9.0.1 is now available and also for all PTS users are a number of new/updated test profiles via OpenBenchmarking.org.

AMD Navi 12 Gets 256-bit memory bus according to Linux drivers, Radeon RX 5600 128-bit

Linux

A lot has been said and spoken already about AMD's upcoming NAVI 12 (RX 5600) and 14 (RX 5500). More information from Linux drivers indicates that AMD Navi 12 gets a 256-bit memory bus and the RX 5600 128-bit, likely GDDR6.

The news arrives today though a user at Germany based 3DCenter forums called Berniyh, he found Navi 12 and Navi 14 in Linux drivers, the two GPUs could end up in the RX 5800 and RX 5600 cards respectively. Navi 12 is mentioned to get a 256-bit memory bus. Navi 14 would, according to previously surfaced drivers, get versions with 3, 4 and 8 GB volume graphics memory but on a 128-bit memory bus.

Linux
  • IO_uring Is More Polished With Linux 5.4

    Added back during the Linux 5.1 cycle was IO_uring for fast and efficient I/O. This new interface allows for queue rings to be shared between the application and kernel to avoid excess copies and other efficiency improvements over the existing Linux AIO code. With Linux 5.4, IO_uring is in even better shape.

    In the months since IO_uring was merged to mainline, we've seen a ton of continued work on it including the likes of a 755x performance improvement. With Linux 5.4, it seems following extensive optimizations by Jens Axboe and others, it's in quite a polished shape.

  • It Turns Out CPU Speculative Execution Can Be Useful For Random Entropy / RNG

    While CPU speculative execution has caused a lot of frustrations over the past two years due to the likes of the Spectre vulnerabilities, it turns out CPU speculative execution can be exploited to be a viable source of random entropy for random number generators.

    Particularly on newer Intel/AMD CPU microarchitectures where speculative execution is much more advanced than hardware from years ago, it's been found that measuring the execution time of loops relying upon speculation is random enough to be a cheap and speedy source of entropy.

    [...]

    Linus Torvalds commented and he believes that this is not very reliable and a simple jitter entropy implementation. But he did post his own proof-of-concept code for improving the jitter entropy code based upon this.

  • Fresh Video Encode/Decode Benchmark Numbers For Xeon Platinum 8280 vs. EPYC 7742

    Given recent updates to the Intel Scalable Video Technology (SVT) open-source video encoders as well as other open-source video encoders/decoders, here is a fresh look at the performance of the AMD EPYC 7742 2P server against the Intel competition with the dual Xeon Platinum 8280.

Peter Bengtsson: How much faster is Redis at storing a blob of JSON compared to PostgreSQL?

Filed under
Graphics/Benchmarks
Server
OSS

First of all, I'm still a PostgreSQL fan-boy and have no intention of ceasing that. These times are made up of much more than just the individual databases. For example, the PostgreSQL speeds depend on the Django ORM code that makes the SQL and sends the query and then turns it into the model instance. I don't know what the proportions are between that and the actual bytes-from-PG's-disk times. But I'm not sure I care either. The tooling around the database is inevitable mostly and it's what matters to users.

Both Redis and PostgreSQL are persistent and survive server restarts and crashes etc. And you get so many more "batch related" features with PostgreSQL if you need them, such as being able to get a list of the last 10 rows added for some post-processing batch job.

I'm currently using Django's cache framework, with Redis as its backend, and it's a cache framework. It's not meant to be a persistent database. I like the idea that if I really have to I can just flush the cache and although detrimental to performance (temporarily) it shouldn't be a disaster. So I think what I'll do is store these JSON blobs in both databases. Yes, it means roughly 6GB of SSD storage but it also potentially means loading a LOT more into RAM on my limited server. That extra RAM usage pretty much sums of this whole blog post; of course it's faster if you can rely on RAM instead of disk. Now I just need to figure out how RAM I can afford myself for this piece and whether it's worth it.

Initial Benchmarks Of CentOS 8.0 & CentOS Stream On Intel Xeon / AMD EPYC

Filed under
Graphics/Benchmarks

With this week's release of the much anticipated CentOS 8.0 as the community/free rebuild of Red Hat Enterprise Linux 8 as well as the surprise announcement of the bleeding-edge, rolling-release CentOS Stream, we have begun benchmarking these enterprise Linux distribution releases. Up today are our first tests of CentOS 7.7 against CentOS 8.0 and the early CentOS Stream state on Intel Xeon Cascadelake and AMD EPYC Rome servers.

This is just the first of our CentOS 8.0 benchmarks over the past few days with more performance tests being worked on, including a cross-distribution comparison of the enterprise Linux x86_64 distributions and more. But for ending out the week, here is an initial look at the CentOS 8.0 performance for those that may be using the weekend downtime for upgrading from CentOS 7.

  • VirtIO-FS Sent In For Linux 5.4 With Better Performance Over VirtIO-9P

    VirtIO-FS as a better approach for sharing folders/files with guest VMs is set to debut in Linux 5.4.

    VirtIO-FS makes use of FUSE and is much faster than virtio-8p that serves a similar purpose for sharing folders/files between the host and guest virtual machines. Directories can be exported from the host and mounted by the guest with VirtIO-FS and is effectively the "glue" between FUSE and VirtIO.

  • UDOO X86 II SBC Combines Intel Braswell SoC with Microchip ATMega32U4 “Arduino” MCU

    UDOO X86 development board was first introduced in a crowdfunding campaign in 2016 with a quad-core Intel Braswell processor coupled with an Arduino 101 compatible Intel Curie module for real-time I/O processing.

    Early July of next year (2019) the Intel processor and module seems to be going so well and have a bright future together with UDOO X86 board and accessories becoming broadly available. But life can be cruel at times, and Intel announced their plan to discontinue Intel Curie and other IoT projects just a few weeks later with the last shipment scheduled for July 2018.

  • Intel's Mesa Drivers Point To Even More Comet Lake Parts

    There were already 18 new PCI IDs for Intel's open-source OpenGL/Vulkan Linux graphics drivers for forthcoming Comet Lake processors with UHD Graphics, but now it appears there are even more models en route.

    As of Wednesday, three more PCI IDs were added for Comet Lake, making more than 20 different PCI IDs for graphics on Comet Lake processors. Granted, some of the PCI IDs are reserved for pre-production models / engineering samples or otherwise reserved for possible future revisions that aren't necessarily planned for market at this time, but either way it's a lot.

Why we shouldn’t blame ourselves for the Linux desktop’s microscopic marketshare

Well, that was three interesting articles on the same topic on the same day, namely, billionaires. And read in turn they explain exactly why the Linux Desktop is still at such a marginal market share, and why that’s not because we, who work hard on it, are failures who have been doing the wrong thing all the time. It is in the first place policies, bought with money, that allowed people to build monopolies, taxing individuals and so becoming even more rich and powerful. However, what it is about, is the question: why is Bill Gates not in jail for life with all his wealth stripped off? He’s a criminal, and his crime has directly harmed us, the people working on free software, on the Linux Desktop. So, to make things painfully clear: Bill Gates made it so that his company would tax every computer sold no matter whether it ran Windows or not. If a manufacturer wanted to sell computers running Windows, all the computers it sold were taxed by Microsoft. He would get paid for the work a Linux distribution was doing, and the Linux distribution would not get that money. Read more

    2. Gimp Unlike Tailor Brands, GIMP is more of a photo editor which means that it comes with way more tools and features. If you want to do more than logo designing, then GIMP is your right choice. It comes with a customizable interface that not only covers cosmetics, but also the behavior of the various tools that it has. There are photo enhancement tools that help you to get rid of image distortions, colors, and other imperfections. Another benefit is support for multiple file formats viz. JPEG, PSD, PNG, and GIF.

    I am a Mexican old-guard user of Linux since 2001. I studied Electronic Engineering, and I have been working in that field since 1989. I learnt all sorts of Linux stuff because I love to learn by myself. In addition, I love to read historical detective novels, lots of science fiction, and go to the movies with my husband. I love philosophy, symbolism and many alternative ideas about everything. I also like to have long, friendly debates about everybody’s presumptions (or assumptions?). I try to be open-minded, specially in this times when everyone’s getting polarized Mexico about our President. I used to be an athletic gal, but now I am a total coach-potato! Thanks, Netflix!

SUSE Continues Working On Linux Core Scheduling For Better Security

SUSE and other companies like DigitalOcean have been working on Linux core scheduling to make virtualization safer particularly in light of security vulnerabilities like L1TF and MDS. The core scheduling work is about ensuring different VMs don't share a HT sibling but rather only the same VM / trusted applications run on siblings of a core. SUSE's Dario Faggioli presented at the KVM Forum 2019 at the end of October in Lyon, France. Dario's presentation covered the latest work on core-scheduling for virtualization.
