CPU Performance

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.

Video Conversion – Handbrake v1.0.2: link

Handbrake is a media conversion tool that was initially designed to help DVD ISOs and Video CDs into more common video formats. For HandBrake, we take two videos and convert them to x264 format in an MP4 container: a 2h20 640x266 DVD rip and a 10min double UHD 3840x4320 animation short. We also take the third video and transcode it to HEVC. Results are given in terms of the frames per second processed, and HandBrake uses as many threads as possible.

Compression – WinRAR 5.4: link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2017. 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.

Point Calculations – 3D Movement Algorithm Test v2.1: 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 wins 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. We are using the latest version of 3DPM, which has a significant number of tweaks over the original version to avoid issues with cache management and speeding up some of the algorithms.

Rendering – POV-Ray 3.7.1b4: 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 2-3 minutes on high end platforms.

Synthetic – 7-Zip 9.2: link

As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.

    Does anyone know if the M.2 slot below supports double-sided drives, or is it single-sided only? Reply

    It's interesting how the ASRock B450 K4 is significantly worse than the B350 version in many tests.

    I wonder if this result will change if a Ryzen 2000 series CPU is used.

    Seems they dropped the support for Bristol Ridge on all B450 boards.
    Actually I have yet to find any B450 board with Bristol Ridge support.

    this was discussed a few weeks ago. They ran out of room for additional hardware profiles in the BIOS and were forced to choose between using bigger and more expensive chips, or dropping the oldest CPUs from compatibility lists. Unsurprisingly for a budget product they're choosing to drop support rather than spend more for a niche case.

    Who in their right mind would go over a Bristol Ridge APU vs a Ryzen APU in a new bought system? Reply

    There are plenty of Ebay penny pinchers who can't be bothered to think about what "price/performance" means. Reply

    Poor Gavin. He's so tired his bloodshot eyes are making him see red heatsinks and RAM slots on the B450 ITX board. Reply

    That and Gavin has started using Google Translate to convert from his apparently native Chinese to English, without any form of grammar checking afterward. Reply

    You keep mentioning the red heatsinks and RAM slots on the ITX board, yet the photos do not show red heatsinks or RAM slots. Reply
