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.

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.

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: 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 5.4: 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.

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.

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 AVX mode, the FX-8800P scores 557.6, and the 200GE scores 858.0.

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).

CPU Benchmark Analysis

As we perhaps expected, the Zen-based AMD Athlon jumps all over the Carrizo CPU in all of our tests, and usually by a healthy margin of up to 40%. POV-Ray was close, given that it allows the Carrizo CPU to use all of its threads at higher IPC, but the fact is that an extra $24 (CPU+Motherboard) can get a lot of performance.

    I looked on newegg, none of the <$100 atom boards appeared to have support for an m.2 ssd. I did see one with the obsolescent mSATA standard that would let you either avoid spinning rust entirely or build a baby nas without putting the OS on a data drive. OTOH I did at least see a model with 4 sata ports instead of only 2.
  • LoneWolf15 - Monday, August 26, 2019 - link

    Atom does not support this. However, mSATA is good enough for boot; you don't need massive I/O throughput, just a 128GB to boot the OS, and then use the SATA ports all for drives.
  • bananaforscale - Thursday, August 15, 2019 - link

    Not all Atoms have AES-NI tho. Excavator does.
  • MASSAMKULABOX - Saturday, August 17, 2019 - link

    I'm not sure this will really play that well against Ice-lake ? We need to see the 3200ge/3400ge and then the next gen APU with Zen3/Navi Small on board, about 2020 q1. THAT should be something to write home about. i7 perf with 1060 gfx in a single sock. Interesting to see stuff from the lower end tho.
  • LoneWolf15 - Tuesday, August 27, 2019 - link

    Most modern Atoms do have AES-NI. All current Gemini Lake Atoms support it, and all previous Apollo Lake and Braswell Atoms did as well. Intel is no longer segmenting that out, as it's highly useful for embedded scenarios like NAS and appliance processors
  • LoneWolf15 - Monday, August 26, 2019 - link

    Probably use an LSI whitebox controller in the PCIe x16 slot for storage, or even a caching RAID controller.
    That said, I've seen far better Atom alternatives, including ones with dual-NICs that make them a better proposition in the ITX market.
  • bill.rookard - Thursday, August 15, 2019 - link

    Remember, with built in onboard video, that PCI-E slot could easily hold a RAID or SATAx4 connector for more drives for a NAS build.... At that point 4x 6TB drives would be good for almost a 20TB server using ZFS RAIDZ1

    Independent computer stores that want to offer builds that can compete or even undercut the cheapest Office offerings from Dell and HP? Dell cheapest Inspiron is €379 with a Pentium G5400, 7200 rpm 1 TB HDD and 4 GB RAM.
  • blppt - Wednesday, August 14, 2019 - link

    Can't even use it as a good HTPC---unless i'm mistaken the Radeon 7 doesn't do hardware 4k hevc full decode. And the 8800P would choke on most intense HEVC 4k vids.

    I *guess* you could add a cheapo 1030 or something to solve that problem, but why not start with a setup with integrated graphics from this century?

    Like the max 7-8W much, much cheaper raspberry pi 4?
