The ASRock Z270 Gaming-ITX/ac Review

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 leave the BIOS settings at default and memory at JEDEC for these tests, making it very easy to see which motherboards have MCT enabled by default.

As it can be summarized by all of the following graphs, the ASRock Z270 Gaming ITX/ac falls victim to its own default BIOS settings, as it is the only motherboard that does not have MCT enabled by default. As such, it always falls shortly behind all other Z270 motherboards, especially in multi-threaded performance tests.

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.

    It's all tweets taking up the right hand side of the web page that gives users absolutely no context on what is being discussed. This really needs to go back to a hardware and news site with real reviews that don't chop up graphs with different products for different benchmarks.

    Intel released a microcode update in April to fix the Skylake hyperthreading flaw (a crash/data corruption bug) but guess what AsRock's BIOS for the 170 version of this board is at? 2016, dude.

    Just peddle a new board instead of providing the most minimal amount of customer service. We're supposed to just turn off hyperthreading, apparently.

    AsRock should be tarred and feathered by the tech press but, instead, no one wants to talk about practices like this at all. Just push the latest thing. Am I surprised that Anandtech is clearly oblivious about the hyperthreading bug and AsRock's lack of support for the 170 board? Nope.

    "and the 10Mbps ports are now called “USB 3.1 Gen 2”" - I suppose 10Gbps...

    Small correction: I have this board, and it drives my two 4k displays at 60hz without issue (displayport and HDMi 2.0). So your article is wrong on this count.
    It is capable of driving three 4k displays at 60hz if you attach a third monitor to the thunderbolt 3 port (displayport alternate mode). I have found several sources online doing just that.

    Oh no. They made SATA Express port. Don't tell me it's going to make a comeback now...
  • edzieba - Tuesday, September 19, 2017 - link

    They've been standard on every board I've seen for years. It takes up barely more space than the pair of SATA connectors everyone uses it as, and otherwise serves as a handy pair of PCIe lanes for front panel modules.

    A shame ASRock dropped a USB port over the previous Z170 Gaming ITX. Though at this point, I'm waiting for Z370 to see how the notional i7-8xxx compares to the i7-7820x on ASRock's X299 ITX board (probably a performance regression for most workloads, but dual m.2 NAND SSDs plus an Optane cache is a tempting option for ITX).

    I'm still waiting for a mITX-board with two M.2 slots, so I can ditch cables alltogether. One small fast M.2 for the OS and one cheaper big one for storage. Add a picoPSU and you got rid of all the cables unnecessary cables.
  • wolfemane - Tuesday, September 19, 2017 - link

    Then what you are looking for is the Asus z270i Strix board . 1 sata/pcie m.2 slot and 1 pcie m.2 slot.

    Get rid of all this fancy stuff noone really needs and bring the price down to a reasonable level doing so and I'm interested.
