CPU Performance: Web and Legacy Tests

While more the focus of low-end and small form factor systems, web-based benchmarks are notoriously difficult to standardize. Modern web browsers are frequently updated, with no recourse to disable those updates, and as such there is difficulty in keeping a common platform. The fast paced nature of browser development means that version numbers (and performance) can change from week to week. Despite this, web tests are often a good measure of user experience: a lot of what most office work is today revolves around web applications, particularly email and office apps, but also interfaces and development environments. Our web tests include some of the industry standard tests, as well as a few popular but older tests.

We have also included our legacy benchmarks in this section, representing a stack of older code for popular benchmarks.

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

Speedometer 2: JavaScript Frameworks

Our newest web test is Speedometer 2, which is a accrued test over a series of JavaScript frameworks to do three simple things: built a list, enable each item in the list, and remove the list. All the frameworks implement the same visual cues, but obviously apply them from different coding angles.

Our test goes through the list of frameworks, and produces a final score indicative of ‘rpm’, one of the benchmarks internal metrics. We report this final score.

Google Octane 2.0: Core Web Compute

A popular web test for several years, but now no longer being updated, is Octane, developed by Google. Version 2.0 of the test performs the best part of two-dozen compute related tasks, such as regular expressions, cryptography, ray tracing, emulation, and Navier-Stokes physics calculations.

The test gives each sub-test a score and produces a geometric mean of the set as a final result. We run the full benchmark four times, and average the final results.

Mozilla Kraken 1.1: Core Web Compute

Even older than Octane is Kraken, this time developed by Mozilla. This is an older test that does similar computational mechanics, such as audio processing or image filtering. Kraken seems to produce a highly variable result depending on the browser version, as it is a test that is keenly optimized for.

The main benchmark runs through each of the sub-tests ten times and produces an average time to completion for each loop, given in milliseconds. We run the full benchmark four times and take an average of the time taken.

3DPM v1: Naïve Code Variant of 3DPM v2.1

The first legacy test in the suite is the first version of our 3DPM benchmark. This is the ultimate naïve version of the code, as if it was written by scientist with no knowledge of how computer hardware, compilers, or optimization works (which in fact, it was at the start). This represents a large body of scientific simulation out in the wild, where getting the answer is more important than it being fast (getting a result in 4 days is acceptable if it’s correct, rather than sending someone away for a year to learn to code and getting the result in 5 minutes).

In this version, the only real optimization was in the compiler flags (-O2, -fp:fast), compiling it in release mode, and enabling OpenMP in the main compute loops. The loops were not configured for function size, and one of the key slowdowns is false sharing in the cache. It also has long dependency chains based on the random number generation, which leads to relatively poor performance on specific compute microarchitectures.

3DPM v1 can be downloaded with our 3DPM v2 code here: 3DPMv2.1.rar (13.0 MB)

x264 HD 3.0: Older Transcode Test

This transcoding test is super old, and was used by Anand back in the day of Pentium 4 and Athlon II processors. Here a standardized 720p video is transcoded with a two-pass conversion, with the benchmark showing the frames-per-second of each pass. This benchmark is single-threaded, and between some micro-architectures we seem to actually hit an instructions-per-clock wall.

GeekBench4: Synthetics

A common tool for cross-platform testing between mobile, PC, and Mac, GeekBench 4 is an ultimate exercise in synthetic testing across a range of algorithms looking for peak throughput. Tests include encryption, compression, fast Fourier transform, memory operations, n-body physics, matrix operations, histogram manipulation, and HTML parsing.

I’m including this test due to popular demand, although the results do come across as overly synthetic, and a lot of users often put a lot of weight behind the test due to the fact that it is compiled across different platforms (although with different compilers).

We record the main subtest scores (Crypto, Integer, Floating Point, Memory) in our benchmark database, but for the review we post the overall single and multi-threaded results.

    Unfortunately, we never got any of those. I'm recently stretched six ways from Sunday. Pulled an all-nighter just to even get to this point in the review process. As much as people would love me just to bench CPUs all day every day, even in lockdown I've got these CPUs, EPYC, Motherboards, Xeons, laptops to test, as well as news coverage and all the behind the scenes stuff no-one ever sees. Writing isn't a quick process, either.

    Surely Ian you can just use the AI wirter now :)

    The AI Writer read the comments and now just fanboy-flames.

    Appreciate the reply! I think the fact that you never got those current-gen i3s and i5s is not on you, but on Intel. If they want their stuff reviewed, they know they need to send some samples. Unless, of course, they're afraid of the test results. Which they might just be.

    I just noticed in the "AMD 500 SERIES CHIPSET PROCESSOR SUPPORT" chart; 4000 series/Zen2 based desktop APUs are not represented. An oversight? or is AMD trying to say something?

    There's got to be something strange going on with the 7700k system. In several benchmarks the 6700k outperforms the 7700k, even though the only difference between them is the 7700k is clocked higher. Under no circumstances should the 6700k outperform the 7700k.

    Were the Skylake and Kaby lake systems tested with different motherboards or with different BIOS revisions? Its possible some security patch was active on one system but not on another.

    You should have benched it against a Xeon E-2174G. At least that's the most modern 4C8T CPU Intel sells right now. But I look forward to seeing how it does against the i3-i3-10320 to see if Intel still has the IPC-clockspeed crown or not.
  • schujj07 - Friday, May 8, 2020 - link

    The performance of the i3-10320 will be very similar to the 7700k. The i3 has clock speeds of 3.8/4.6 and the 7700k is 4.2/4.5. That means that on single threaded the 10320 will be slightly faster but in heavily threaded work loads the 7700k will probably be faster due to the higher base clock. This is know because both CPUs are on the Sky Lake architecture and will have the same IPC. Therefore we can infer what the 10320 will do based on what we see the 7700k doing in this review.

    I think it'd be nice to see generational to generational improvements on intel vs AMD's side of things, you guys use to do that everytime a new generation came out. It'd be nice to see how far my 4th gen Intel chip has gone vs a new gen now.

    Again your garbage reviews. Apparently all the cpus on the world are bottlenecking 1080 gtx @ 1080p except 3300x.

    Do you even think when checking the results. This thing happens constantly, especially when you test low end garbage amd cpus.
