CPU Performance, Short Form

For our motherboard reviews, we use our short form testing method. These tests usually focus on if a motherboard is using MultiCore Turbo (the feature used to have maximum turbo on at all times, giving a frequency advantage), or if there are slight gains to be had from tweaking the firmware. We put the memory settings at the CPU manufacturers suggested frequency, making it very easy to see which motherboards have MCT enabled by default.

For B550 we are running using Windows 10 64-bit with the 1909 update.

Rendering - Blender 2.7b: 3D Creation Suite - link

A high profile rendering tool, Blender is open-source allowing for massive amounts of configurability, and is used by a number of high-profile animation studios worldwide. The organization recently released a Blender benchmark package, a couple of weeks after we had narrowed our Blender test for our new suite, however their test can take over an hour. For our results, we run one of the sub-tests in that suite through the command line - a standard ‘bmw27’ scene in CPU only mode, and measure the time to complete the render.

Streaming and Archival Video Transcoding - Handbrake 1.1.0

A popular open source tool, Handbrake is the anything-to-anything video conversion software that a number of people use as a reference point. The danger is always on version numbers and optimization, for example the latest versions of the software can take advantage of AVX-512 and OpenCL to accelerate certain types of transcoding and algorithms. The version we use here is a pure CPU play, with common transcoding variations.

We have split Handbrake up into several tests, using a Logitech C920 1080p60 native webcam recording (essentially a streamer recording), and convert them into two types of streaming formats and one for archival. The output settings used are:

  • 720p60 at 6000 kbps constant bit rate, fast setting, high profile
  • 1080p60 at 3500 kbps constant bit rate, faster setting, main profile
  • 1080p60 HEVC at 3500 kbps variable bit rate, fast setting, main profile

Rendering – POV-Ray 3.7.1: Ray Tracing - link

The Persistence of Vision Ray Tracer, or POV-Ray, is a freeware package for as the name suggests, ray tracing. It is a pure renderer, rather than modeling software, but the latest beta version contains a handy benchmark for stressing all processing threads on a platform. We have been using this test in motherboard reviews to test memory stability at various CPU speeds to good effect – if it passes the test, the IMC in the CPU is stable for a given CPU speed. As a CPU test, it runs for approximately 1-2 minutes on high-end platforms.

Compression – WinRAR 5.60b3: link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30-second 720p videos.

Encoding: WinRAR 5.60b3

Synthetic – 7-Zip v1805: link

Out of our compression/decompression tool tests, 7-zip is the most requested and comes with a built-in benchmark. For our test suite, we’ve pulled the latest version of the software and we run the benchmark from the command line, reporting the compression, decompression, and a combined score.

It is noted in this benchmark that the latest multi-die processors have very bi-modal performance between compression and decompression, performing well in one and badly in the other. There are also discussions around how the Windows Scheduler is implementing every thread. As we get more results, it will be interesting to see how this plays out.

Point Calculations – 3D Movement Algorithm Test: link

3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz, and IPC win in the single thread version, whereas the multithread version has to handle the threads and loves more cores. For a brief explanation of the platform agnostic coding behind this benchmark, see my forum post here.

System: 3D Particle Movement v2.1

Neuron Simulation - DigiCortex v1.20: link

The newest benchmark in our suite is DigiCortex, a simulation of biologically plausible neural network circuits, and simulates activity of neurons and synapses. DigiCortex relies heavily on a mix of DRAM speed and computational throughput, indicating that systems which apply memory profiles properly should benefit and those that play fast and loose with overclocking settings might get some extra speed up. Results are taken during the steady-state period in a 32k neuron simulation and represented as a function of the ability to simulate in real time (1.000x equals real-time).

    Typo on last paragraph on last page: "For $190 with Wi-Fi, or $190 without".
  • Ryan Smith - Wednesday, July 22, 2020 - link

    Thanks!

    Perhaps I missed it, but it would be helpful to include a link to a X570 vs B550 chipset comparison table.
  • crimson117 - Wednesday, July 22, 2020 - link

    Good one here: https://www.gamersnexus.net/guides/3582-amd-chipse...

    Biggest difference is that the B550 chipset itself doesn't support PCIe 4.0, but you still get support from the CPU, just fewer applicable slots. And a positive is that B550 doesn't require active cooling, unlike x570.
  • Skeptical123 - Friday, July 24, 2020 - link

    people need to get over that active cooling thing, it's a minor caveat at best, as much as people bring it you think it would be something actually negative like price, supply, driver support etc...
  • Alexey291 - Sunday, July 26, 2020 - link

    Its just another potential point of failure so it inherently a negative.
  • soresu - Sunday, July 26, 2020 - link

    I'll get over the "actuve cooling thing" when it doesn't add to the sound of the PC - some of us actually care about that even if you don't.

    To say nothing of the fact that basically every X570 mobo uses tiny, thin fans which are the opposite of silent if they ramp up to any significant number of RPM.
  • Oxford Guy - Saturday, August 1, 2020 - link

    "And a positive is that B550 doesn't require active cooling, unlike x570.

    False. X570 does not require active cooling.
  • cwolf78 - Thursday, November 18, 2021 - link

    I know this is an old comment, but I can't let this stand. X570 absolutely *DOES* require active cooling. True, the fan may not run under low-load on some boards (MSI Tomahawk, for example) but it is needed otherwise. The X570S is the chipset that does not require active cooling.

    Still find it funny to see "Gaming" and "Wifi" on the same product, when we all know (or at least should know) that WiFi kills online gaming performance.
