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'm still using my A8-3850 as my HTPC, so... :shrug:

    Cheers!

    They could've at least added more USB ports.
  • DanNeely - Wednesday, August 14, 2019 - link

    I'm wondering if no more were available. This is a mobile chip, and while I can't find IO specs, 4 each USB2 and USB3 (the other 4 USB are in a pair of headers) along with 2 SATA is about right for a laptop. 4 external 3.0 ports, 2x 2.0 ports for keyboard and touchpad, and 2 more for optional misc internal device connections.

    Wow, there must be a lot of unsold and unused Carrizos in somebody's warehouse!
  • artk2219 - Thursday, August 15, 2019 - link

    There are, AMD had TONS of stock left over from carrizo and Llano, to the point where you can still find a lot new old stock Llano chips. We will be seeing these carrizo and honestly even Bristol Ridge parts for years.

    Use case: Open source hardware router (with PCIe network card, natch).

    Fight me.
  • evernessince - Wednesday, August 14, 2019 - link

    Consumes too much power for that. The ARM chips inside many modern routers are far more efficient.

    Sure, for a handful of homebodies surfing the net, gaming etc. If you have a business environment, with layer 7 filtering, a mail server, multiple routed IPSEC VPN nodes, and come under moderate bot attacks (cuz server, road warrior access, etc) Pi's and other ARMs bog down. I've had one come under an attack on a Monday morning when everyone was logging in and checking email, and that morning VPN tunnel traffic burst, over heated and shut down. Until the attack stopped, I couldn't get it to stay up. 90 minutes of unhappy clients isn't worth the delta on sunk costs. Athlon GE setup with dual port intel giga nic are rock solid. Under similar circumstances it barely breaks a sweat, It also sustains bandwidth through the tunnels when the traffic is hundreds of smaller transactions from many users throughout the day(10-15%-basically full line speed), and had some 5-7% lower latency.
    Point is it depends. For ~$175-200 you've got a 5-8 year lifespan machine that's virtually trouble free. That's $22 to $40 a year, for a very flexible, highly configuarable router/firewall/dns/dhcp/proxy-server/layer7/VPN/Roadwarrior VPN/VLAN device (also compatible with IPSEC VLANs from Cisco, Juniper, Barracuda, Linksys, Netgear, Sonicwall etc/DynDNS compatability, BGP, even email gateway type filtering)

    yes, it's windows 7 time!

    Is the M.2 NVMe or SATA?
