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.

WebXPRT 3: Modern Real-World Web Tasks, including AI

The company behind the XPRT test suites, Principled Technologies, has recently released the latest web-test, and rather than attach a year to the name have just called it ‘3’. This latest test (as we started the suite) has built upon and developed the ethos of previous tests: user interaction, office compute, graph generation, list sorting, HTML5, image manipulation, and even goes as far as some AI testing.

For our benchmark, we run the standard test which goes through the benchmark list seven times and provides a final result. We run this standard test four times, and take an average.

WebXPRT 2015: HTML5 and Javascript Web UX Testing

The older version of WebXPRT is the 2015 edition, which focuses on a slightly different set of web technologies and frameworks that are in use today. This is still a relevant test, especially for users interacting with not-the-latest web applications in the market, of which there are a lot. Web framework development is often very quick but with high turnover, meaning that frameworks are quickly developed, built-upon, used, and then developers move on to the next, and adjusting an application to a new framework is a difficult arduous task, especially with rapid development cycles. This leaves a lot of applications as ‘fixed-in-time’, and relevant to user experience for many years.

Similar to WebXPRT3, the main benchmark is a sectional run repeated seven times, with a final score. We repeat the whole thing four times, and average those final scores.

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.

    So he makes a point about why people want a CPU and he is instant fanboy? Well you certainly got the boy part down pat..
  • Jorgp2 - Thursday, October 31, 2019 - link

    What are you talking about?

    Zen 2 only has a tiny IPC advantage over Skylake.
  • Spunjji - Friday, November 1, 2019 - link

    10% isn't tiny, especially when boosting clock speeds by 10% is no longer trivial.
  • Korguz - Friday, November 1, 2019 - link

    imagine what it would be like if the clock speeds were higher... if zen 2 is this close, or faster with the clockspeed disadvantage it has now.. what will it be like if zen 2 was hitting 4.6+ ghz ???
  • outsideloop - Friday, November 1, 2019 - link

    We have a few months until Zen 3 clocks will leak.
  • MDD1963 - Thursday, November 7, 2019 - link

    Don't a full 10% of the 3900X samples actually have a core or two hit their advertised 4600 MHz for about 5 full consecutive seconds....sometimes? :)
  • Korguz - Friday, November 8, 2019 - link

    dont intel cpus NEED the higher clocks in order to have the performance they get ? clock them at the ryzen equivilents.. and see how well they perform.. when will people realize clock speed isnt everything ??
  • amnesia0287 - Friday, November 8, 2019 - link

    What would it be like if it hit 6ghz?

    Does it matter since it can’t?

    I am very eager to see Zen 3 tho. Regardless of all the fanboys. I feel like it’s very much a mixed bag to chose between intel and amd just cause of some of the instruction sets and #of threads used by various things.

    But if even half of the stuff about Zen3 is true 2020 should be AMDs year as I don’t believe anything intel launches until 2021 is really gonna be competitive.

    Zen 2 has more like 13%-15% IPC gain over released Intel CPU's right now at same clock speeds depending on work load. There was a video on Youtube where one of the bigger YT channels did a side by side of AMD Zen 2 CPU and Intel 9900K both @4GHz and I was surprised that the AMD chip was ahead in most everything by a fair amount.

    When it came to gaming though Intel had a slight lead in a few games that seemed to favor Intel. But there were also games that AMD got wins from a s well. This would explain why AMD with a CPU with same core count is now able to match Intel even though AMD has a lower clock speed and even come close or match in a lot of games. I am no fanboy for either camp I currently only own Intel based systems but would be more than willing to look at either camps hardware when I do my next set of upgrades. That is just how good things are now on either side ans with AMD finally back in the game and putting pressure on Intel prices are also now getting better on the Intel side of the street as well. It is a win for everyone when things like this start happening.

    Hey, it's a good thing the 3900X doesn't have slow cores then, does it :)

    Seriously, though. i3-9350KF exists, go buy that if you want clock speed :P
