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.

    The 8700k is also pulling 150W while the 8086k is 95W. Something's not right there.
  • _mat - Wednesday, November 7, 2018 - link

    There can be two reasons why that is the case:

    1) The mainboard settings for Power Limits were different.
    2) The 8086K ran into Power Limit 1 while the 8700K was not.

    Whatever is the case here, it is no doubt that the 8086K did run into Power Limit 1 after the "Time Above PL1" (= power budget) was depleted. The 95 Watts are exactly the specified TDP of the CPU and Intel recommends this as Power Limit 1 value.

    So the problem here is that the Power Limits and Current Limits of the mainboard are not properly documented and seem to differ between the test candidates. While the 8086K obviously had Power Limits in place, the 9th gen CPUs were benched with no limits at all (only temperature limit at 100 °C on a core).

    Also, the whole page on power consumption needs rework. The TDP does matter depending on the board and its default settings.

    Ian! Many of your tests ( Y-Cruncher multithreaded, apptimer, FCAT - ROTR, WinRAR ), are taking too short of a time. You need some differentiation here! Please make them harder.

    >In case the previous comment was missed.

    I see that the last few pages have included a note about Z390 used because the Z370 board was over-volting the chip? Yet on the Overclocking page we see the Z370 listed with max CPU package power at 168 Watts? Could you list the (default) auto voltage applied by the Asrock Z370 & if appropriate update the charts on OCing page with the Z390 as well?

    "Intel has promised that its 10nm manufacturing process will ramp through 2019, ..."

    Ian, what promises did Intel make 2 years ago about what they would be supplying now?
  • eastcoast_pete - Sunday, October 21, 2018 - link

    My guess is that Intel is now printing those promises in 10 nm font size (easily readable with a standard electron microscope). See, they moved to 10 nm by 2018!
  • ballsystemlord - Sunday, October 21, 2018 - link

    Actually, fonts are measured in points. So, it's 10pt, and it's rather legible.
    But, as for products, I don't see any either.
  • darkos - Sunday, October 21, 2018 - link

    nice review, but: please add a flight simulation such as x-plane and prepar3d or fsx. this is an area that is sadly, missing from your reviews.
  • kasboh - Monday, October 22, 2018 - link

    Do I see it correctly that there is little benefit of HyperThreading with 8 core CPUs?
  • eXterminuss - Monday, October 22, 2018 - link

    I am quiet shocked to see that Anandtech is using a vastly outdated and in parts plainly wrong description for World of tanks:
    1. The enCore engine ist being used in world of tanks for quiet a while now (10 month)
    2.World of tanks is a free to play game, no elements hiden behind a paywall, e. g. no more features for a paying customer than for a freelooter.
    3. Since the outadted EnCore benchmark was used, i would have at least expected to see the Results of that benchmark being posted aswell.
    Sincerly yours,
