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 X570 we are running using Windows 10 64-bit with the 1903 update as per our Ryzen 3000 CPU review.

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).

    The CPU is still quite often the bottleneck for games when running at high framerates.
  • goatfajitas - Wednesday, August 28, 2019 - link

    Possibly if you bought an $800 VC and have a mediocre $200 CPU, but that isnt realistically what anyone would have bought.
  • inighthawki - Wednesday, August 28, 2019 - link

    That's just not true. Go play a game at 720p on lowest settings and you'll very quickly see that even high end CPUs produce a noticeable bottleneck for achieving high framerates.

    The numbers are available to you as well. You can very easily go to Anandtech's bench numbers and compare any two high end CPUs and still see a difference in framerate across many games using the same GPU, even on medium to high settings. It's typically also quite apparent in the 95th percentile metrics.

    Sure if the game is poorly optimized and doesn't offer enough control over graphics settings to reduce the GPU load enough, you won't see much of a difference because of course the GPU will remain the bottleneck in those cases. However if you're shooting for high framerates like 240hz, the CPU is almost always the bottleneck.

    inighthawki um, who would pay $800 for a vid card, and play games at 720P on the lowest settings, regardless what cpu you are running ? that could be done with a $400 vid card depending on the game
  • inighthawki - Thursday, August 29, 2019 - link

    Because not all games are well optimized and can require a strong GPU to hit very high framerates even on low settings. Even with top of the line hardware (both CPU+GPU) on lowest settings, many games cant even hit a stable 144hz.
  • Qasar - Friday, August 30, 2019 - link

    i never understood the reason for needing high frame rates with games.. i have played a few of the games i have over the years with new hardware, and been able to get better FPS, and maybe its just me, but i dont notice the difference. inighthawki " many games cant even hit a stable 144hz. " and what does a refresh rate have to do with frames per second ?? my lowly 75hz monitor works just fine when the games i play are above 75 fps or hz
  • 29a - Friday, August 30, 2019 - link

    Low (<60 fps) framerates give me nausea.
  • Qasar - Friday, August 30, 2019 - link

    29a, then i guess you cant play many console games :-) the games i play, even with the eye candy on max, less AA and AF, rarely go below 75 fps on the current hardware i have :-)
  • inighthawki - Friday, August 30, 2019 - link

    >> and what does a refresh rate have to do with frames per second ??

    Just my poor phrasing because I'm typing quickly. I mean that they cannot maintain 144fps on my 144hz display.

    Perhaps you dont play any games where it makes a significant difference, but for a lot of games once you play at 144hz, playing on a 60hz display is like watching a slideshow. Playing over 75fps on your 75hz display may improve input latency for your game but it wont be any smoother.
  • Qasar - Friday, August 30, 2019 - link

    inighthawki on the contrary, it is noticeably smoother, enough where i notice, and turn a few of the eye candy options down a little if it does look choppy. but i have tried playing a few games on monitors like that, and while it is nice.. not something i am after right now.. but as you mentioned.. could be cause of the games i play, dont need it.. i assume, then, you play a lot of 1st person shooters ?
