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.

    Same to you, who still thinks that Intel CPUs are made purely in USA :D Reply

    I preordered my 9900k on Amazon the second day, inflated prices and all (but still less than other retailers), yet no sign of shipping yet. I guess I still wasn't quick enough to get in line. I just want to know how constrained is the supply Reply

    What do I think? That it is a deliberate act of desperation. It looks like it may draw more power than a 32-Core ThreadRipper per your own charts.

    The motherboard in question was using an insane 1.47v

    For the last decade, you've had the choice between "I want really fast cores!" and "I want lots of cores!". This is the 'now you can have both' CPU, and it's surprisingly not in the HEDT realm. Reply
  • evernessince - Saturday, October 20, 2018 - link

    It's priced like HEDT though. It's priced well into HEDT. FYI, you could have had both of those when the 1800X dropped. Reply

    I noticed initially in the UK the pricing of the 9900K was very close to the 7820X, but now pricing for the latter has often been replaced on retail sites with CALL. Coincidence? It's almost as if Intel is trying to hide that even Intel has better options at this price level. Reply

    Nothing unexpected really. 5Ghz with "better" node that is tuned for higher Frequency. The TDP was the real surprise though, I knew the TDP were fake, but 95 > 220W? I am pretty sure in some countries ( um... EU ) people can start suing Intel for misleading customers.

    For the AVX test, did the program really use AMD's AVX unit? or was it not optimised for AMD 's AVX, given AMD has a slightly different ( I say saner ) implementation. And if they did, the difference shouldn't be that big.

    I continue to believe there is a huge market for iGPU, and I think AMD has the biggest chance to capture it, just looking at those totally playable 1080P frame-rate, if they could double the iGPU die size budget with 7nm Ryzen it would be all good.

    Now we are just waiting for Zen 2.

    It's using it. You can see points increased in both cases. But AMD implemented AVX on the cheap. It takes twice the cycles to execute AVX operations involving 256-bit data, because (AFAIK) it's implemented using 128-bit registers, with pairs of units that can only do multiplies or adds, not both.

    That may be the smart choice; it probably saves significant space and power. It might also work faster with SSE[2/3/4] code, still heavily used (in part because Intel has disabled AVX support on its lower-end chips). But some workloads just won't perform as well vs. Intel's flexible, wider units. The same is true for AVX-512, where the workstation chips run away with it.

    It's like the difference between using a short bus, a full-sized school bus, and a double decker - or a train. If you can actually fill the train on a regular basis, are going to go a long way on it, and are willing to pay for the track, it works best. Oh, and if developers are optimizing AVX code for *any* CPU, it's almost certainly Intel, at least first. This might change in the future, but don't count on it.
