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 leave the BIOS settings at default and memory at JEDEC for the supported frequency of the processor for these tests, making it very easy to see which motherboards have MCT enabled by default.
Rendering - Blender 2.78: link
For a render that has been around for what seems like ages, Blender is still a highly popular tool. We managed to wrap up a standard workload into the February 5 nightly build of Blender and measure the time it takes to render the first frame of the scene. Being one of the bigger open source tools out there, it means both AMD and Intel work actively to help improve the codebase, for better or for worse on their own/each other's microarchitecture.
The ASRock Z370 Gaming-ITX/ac completed our Blender testing in 310 seconds placing it on the bell curve but on the trailing edge. Nothing anomalous here.
Rendering – POV-Ray 3.7: 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.
POV-Ray results show the Gaming-ITX/ac in the middle of this thread heavy benchmark. All boards ran the benchmark at the same clock speed of 4.3 GHz. This particular group of results continues with its very tight set of results with less than 1% difference (margin of error).
Compression – WinRAR 5.4: 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.
Moving on to WinRAR, the ASRock board completed this in 41.3 seconds landing it in the middle of our results. We can see the B360 and H370 boards at the bottom of the pack due to its lack of MCE while the other boards tested boost to the same value.
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.
Our 7Zip results are pretty interesting with the ASRock Z370 Gaming ITX/ac leading an otherwise tightly packed group by a fair amount (over 2K points). In this test, the board boosted all cores to 4.7 GHz to achieve this result whereas others used a less aggressive Multi-Core Enhancement by default.
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.
In 3DPM 2.1, we are seeing the same type of behavior here in the Gaming ITX/ac leading the pack by over 100 points. Here again, this board has more aggressive MCE in this test also running it at 4.7 GHz all cores.
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 DigiCortex results have the Z370 Gaming-ITX with a result of 0.98. Nothing of note with that result. DigiCortex does show a decent spread between results which is different than we have seen previously with 6% separating the best from worst.

I'm not that bullish on this Z370 board - not that there's anything wrong with it, but:- Its Summer 2018 and Z390 boards are being announced all around.
- The Z370 gives up a lot of IO vs the H370, just to gain overclocking.
- The Z390 will have overclocking AND better IO, like 6x 2nd gen USB 3.1
- 8-core i7-9700K ships are imminent. maybe 8 cores without multi-threading won't be better than 6 cores with multi-threading - but do you want to put down your chips without knowing?
- Nvidia's 1180 GPUs are also imminent if the Siggraph announcement is a good enough hint for you.
Seems better to me, to just wait a couple of months

No z390 and NV 2080 .. z370m-itx/ac here, gives up the tb3 and some other stuff? for a lot less cash, good going so far , but wheres asrock overclocking software? has it vanished ...
