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.
Users can access the WebXPRT test at http://principledtechnologies.com/benchmarkxprt/webxprt/
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.

There are certainly occasions where more cores are better than clock speed.Just look at certain mining apps. You can drop the power usage by half and only lose a little processing speed, but drop them to 2 cores at full power instead of 4 and it is a *huge* drop. Been playing with the CPU max speed in Windows power management on my various laptops. The Skylake i5 6300HQ can go down to some seriously low power levels if you play with it a bit. The recent Windows updates have lost a lot of the Intel Dynamic Thermal control though. That's a shame.

Power consumption rules on mobiles parts why would they release an 8 core model?notashill - Friday, October 19, 2018 - link
Because you get more performance at the same power level using more cores at lower clocks. The additional cores are power gated when not in use.evernessince - Saturday, October 20, 2018 - link
Not judging by the power consumption and heat output displayed here.mkaibear - Friday, October 19, 2018 - link
9700K is definitely the way to go on the non-HEDT. 9900K is technically impressive but the heat? Gosh.It's definitely made me consider waiting for the 9800X though - if the 7820X full load power is 145W ("TDP" 140W) at 3.6/4.3, then the 9800X isn't likely to be too much higher than that at 3.8/4.5.
Hrm.

"9700K is definitely the way to go on the non-HEDT."I think you meant to say "Ryzen 5 2600 unless your GPU's so fast, it'll HEAVILY CPU-bind you in gaming" but spelt it wrong ;). The 9700K is a vey good CPU, no doubt, but to claim it the undisputed mainstream champ at it's currently mediocre bang/$ value (so important for the mainstream market) doesn't make any sense, or accurately represent what people in the mainstream are ACTUALLY buying (lots of Ryzen 5 2600's & i5-8400's; both with a MUCH saner claim to the "best overall mainstream CPU" title).

No, I meant to say "9700K is definitely the way to go on the non-HEDT".Don't put words in people's mouth. I don't just game. The video encoding tests in particular are telling - I can get almost a third better performance with the 9700K than I can the r5 2600x.
>"best overall mainstream CPU" title
Please don't straw man either. Nowhere did I say that it was the best overall mainstream CPU (that's the R7 2700X in my opinion), but for my particular use case the 9700K or the 9800X are better suited at present.

Uhm yeah... so where are the 9900k overclocking results the article claims are currently being uploaded? :)watzupken - Friday, October 19, 2018 - link
The i9 processor is expected to be quite impressive in performance. However this review also reveals that Intel is struggling to pull more tricks out of their current 14nm and Skylake architect. The lack of IPC improvement over the last few generations is just forcing them to up the clockspeed to continue to cling on to their edge. Considering that they are launching the new series this late in the year, they are at risk of AMD springing a surprise with their 7nm Zen 2 slated to launch next year.SquarePeg - Friday, October 19, 2018 - link
If the rumored 13% IPC and minimum 500mhz uplift are for real with Zen 2 then AMD would take the performance crown. I'm not expecting very high clocks from Intel's relaxed 10nm process so it remains to be seen what kind of IPC gain they can pull with Ice Lake. It wouldn't surprise me if they had a mild performance regression because of how long they had to optimize 14nm for clock speed. Either way I'm all in on a new Ryzen 3 build next year.
