CPU System Tests

Our first set of tests is our general system tests. These set of tests are meant to emulate more about what people usually do on a system, like opening large files or processing small stacks of data. This is a bit different to our office testing, which uses more industry standard benchmarks, and a few of the benchmarks here are relatively new and different.

All of our benchmark results can also be found in our benchmark engine, Bench.

FCAT Processing: link

One of the more interesting workloads that has crossed our desks in recent quarters is FCAT - the tool we use to measure stuttering in gaming due to dropped or runt frames. The FCAT process requires enabling a color-based overlay onto a game, recording the gameplay, and then parsing the video file through the analysis software. The software is mostly single-threaded, however because the video is basically in a raw format, the file size is large and requires moving a lot of data around. For our test, we take a 90-second clip of the Rise of the Tomb Raider benchmark running on a GTX 980 Ti at 1440p, which comes in around 21 GB, and measure the time it takes to process through the visual analysis tool.

System: FCAT Processing ROTR 1440p GTX980Ti Data

FCAT is a purely single threaded task, and it takes benefits from the top frequency parts and high IPC from Intel. On the AMD front, the Ryzen 5 parts are scoring better than the Ryzen 7 parts, but are within an error margin.

Dolphin Benchmark: link

Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that ray traces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes (1052 seconds).

System: Dolphin 5.0 Render Test

Dolphin is also a single threaded test, and has historically had benefits on Intel CPUs. The new Ryzen-2000 series, with extra IPC and frequency, are pushing ahead of Intel's Skylake parts.

3D Movement Algorithm Test v2.1: link

This is the latest version of the self-penned 3DPM benchmark. The goal of 3DPM is to simulate semi-optimized scientific algorithms taken directly from my doctorate thesis. Version 2.1 improves over 2.0 by passing the main particle structs by reference rather than by value, and decreasing the amount of double->float->double recasts the compiler was adding in. It affords a ~25% speed-up over v2.0, which means new data.

System: 3D Particle Movement v2.1

For this multi-threaded test, the new 8-core Ryzen 7 2700X pulls further head of Intel's 8-core Skylake-X compared to the 1800X. At six cores however, the Coffee Lake i7-8700K is sandwiched between the Ryzen 5 2600X and Ryzen 5 2600.

Agisoft Photoscan 1.3: link

Photoscan stays in our benchmark suite from the previous version, however now we are running on Windows 10 so features such as Speed Shift on the latest processors come into play. The concept of Photoscan is translating many 2D images into a 3D model - so the more detailed the images, and the more you have, the better the model. The algorithm has four stages, some single threaded and some multi-threaded, along with some cache/memory dependency in there as well. For some of the more variable threaded workload, features such as Speed Shift and XFR will be able to take advantage of CPU stalls or downtime, giving sizeable speedups on newer microarchitectures.

System: Agisoft Photoscan 1.3.3 (Large) Total Time

Photoscan is a variable threaded test, and time improvement from the 1800X to the 2700X shows the extra TDP and Precision Boost 2 can literally shave minutes from a test. Intel's slower mesh architecture of Skylake-X on the 8-core 7820X compared to the ring architecture of the Coffee Lake 8700K means that the two fewer cores on the 8700K allows them to draw level, but they are still four minutes or so behind the Ryzen 7 2700X. The big 18-core Intel CPU, the i9-7980XE, is needed to win here.

Civilization6 AI Test

Our Civilization AI test uses the steam version of Civilization 6 and runs the in-game AI test to process 25 rounds of an example end-game. We run the benchmark on our GTX 1080 at 1080p Medium to ensure that rendering is not a limiting factor, and the results are given as the geometric mean of the 25 rounds in the test, to give the average time to process one round of AI.

System: Civilization 6 AI (1080p Medium + GTX 1080)

Parts of the AI test can use multiple threads, however the extra single core performance on Intel does push those parts into the lead.

    I was wondering about gaming, so there is no mistake there as Ryzen 2 seems to top Intel.
    As of right now, I don't seem to find memory specs in the review yet, safe to assume you did as always, highest non-OC so Ryzen is using faster DRAM?
    Also yet to spot memory letency, any chance you have some numbers at 3600MHz vs Intel? Thanks.
  • jjj - Thursday, April 19, 2018 - link

    And just between us, would be nice to have some Vega gaming results under DX12.
  • aliquis - Thursday, April 19, 2018 - link

    Would be nice if any reviewer actually benchmarked storage devices maybe even virtualization because then we'd see meltdown and spectre mitigation performance. Then again do AMD have any for spectre v2 yet? If not who knows what that will do.

    I notice that that systems had higher memory, but for me I believe single threaded performance is more important that more cores. But it would be bias if one platform is OC more than another. Personally I don't over clock - except for what is provided with CPU like Turbo mode.

    One thing that I foresee in the future is Intel coming out with 8 core Coffee Lake

    But at least it appears one thing is over is this Meltdown/Spectre stuff

    Intel 8 core CL won't stop the bleeding, lose more profits making them "cheap" vs a new Ryzen 7nm with at least 10% more clocks and 10% more IPC, RIP.
  • HStewart - Thursday, April 19, 2018 - link

    I just have to agree to disagree on that statement - especially on "cheap" statement
  • ACE76 - Thursday, April 19, 2018 - link

    CL can't scale to 8 cores...not without done serious changes to it's architecture...Intel is in some trouble with this Ryzen refresh...also worth noting is that 7nm Ryzen 2 will likely bring a considerable performance jump while Intel isn't sitting on anything worthwhile at the moment.
  • Alphasoldier - Friday, April 20, 2018 - link

    All Intel's 8cores in HEDT except SkylakeX are based on their year older architecture with a bigger cache and the quad channel.

    So if Intel have the need, they will simply make a CL 8core. 2700X is pretty hungry when OC'd, so Intel don't have to worry at all about its power consuption.

    > 2700X is pretty hungry when OC'd
    And Intel chips aren't? If Zen+ is already on Intel's heels for both performance per watt and raw frequency, a 7nm chip with improved IPC and/or cache is very likely going to have them pull ahead by a significant margin. And even if it won't, it's still going to eat into Intel's profit as their next tech is 10nm vs. AMD's 7nm, meaning more optimal wafer estate utilization for the latter.

    AMD has really climbed back at the top of their game; I've been in the Intel camp for the last 12 years or so, but the recent developments throw me way back to K7 and A64 days. Almost makes me sad that I won't have any reason to move to a different mobo in the next 6–8 years or so.

    Amusing to look back given how things panned out. So yes, Intel released the 9900K, but it was 100% more expensive than the 2700X. :D A complete joke. And meanwhile tech reviewers raved about a peasly 5 to 5.2 oc, on a chip that already has a 4.7 max turbo (major yawn fest), focusing on specific 1080p gaming tests that gave silly high fps number favoured by a market segment that is a tiny minority. Then what happens, RTX comes out and pushes the PR focus right back down to 60Hz. :D

    I wish people to stop drinking the Intel/NVIDIA coolaid. AMD does it aswell sometimes, but it's bizarre how uncritical tech reviewers often are about these things. The 9900K dragged mainstream CPU pricing up to HEDT levels; epic fail. Some said oh but it's great for poorly optimised apps like Premiere, completely ignoring the "poorly optimised" part (ie. why the lack of pressure to make Adobe write better code? It's weird to justify an overpriced CPU on the back of a pro app that ought to run a lot better on far cheaper products).
