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.

    Oh I thought they use remote debugging.

    Only thing I can think of as a gaming use for those would be to pass through a gpu each to several VMs. Reply

    @Ryan, "There’s no way around it, in almost every scenario it was either top or within variance of being the best processor in every test (except Ashes at 4K). Intel has built the world’s best gaming processor (again)."

    Am I reading the iGPU page wrong? The occasional 100+% handicap does not seem to be "within variance".

    if you noticed 2700x is faster in half benchmarks for games but they didnt include it Reply

    That wasn't a negative critique of the review, just the opposite in fact: from the selection of benchmarks you provided, it is EASY to see that given more GPU power, the new Intel chips will clearly outperform AMD most of the time - generally with average, but specifically minimum frames. From where I'm sitting - 3570K+1080Ti - I think I could save a lot of money by getting a 2600X/2700X OC setup and not miss out on too many fpses. Reply

    I think anyone with any sense (and the constraints of a budget / missus) will be stupid to buy this CPU for gaming. The sensible thing to do is to buy the AMD chip that provides 99% of the gaming performance for half the price (even better value when you factor in the mobo) and then to plough that money into a better GPU, more RAM and / or a better SSD. The savings from the CPU alone will allow you to invest a useful amount more into ALL of those areas. There are people who do need a chip like this but they are not gamers. Intel are pushing hard with both the limitations of their tech (see: stupid temperatures) and their marketing BS (see: outright lies) because they know they're currently being held by the short and curlies. My 4 year old i5 may well score within 90% of these gaming benchmarks because the limitation in gaming these days is the GPU. Sorry, Intel, wrong market to aim at. Reply

    I like how you said limitations in tech and point to temps, like any gamer cares about that. Every game wants raw performance, and the fact remains intel systems are still easier to go about it. The reason is simple, most gamers will upgrade from another intel system and use lots of parts from it that work with current generation stuff.

    Its like the whole Gsync vs non gsync. Its a stupid arguement, its not a tax on gsync when you are buying the best monitor anyways.
  • philehidiot - Saturday, October 20, 2018 - link

    Those limitations affect overclocking and therefore available performance. Which is hardly different to much cheaper chips. You're right about upgrading though. Reply

    The AVX 512 numbers look suspicious. Both common sense and other examples online suggest that AVX512 should improve performance by much less than a factor 2. Additionally, AVX-512 causes varying amounts of frequency throttling; so you;re not going to get the full factor 2.

    This suggests to me that your baseline is somehow misleading. Are you comparing AVX512 to ancient SSE? To no vectorization at all? Something's not right there.
