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.

    I have two wants.

    1 - I really want to see the overclocked 9600k vs overclocked 8600k, as the chart differences of it in this early draft of your 9900k-focused review are likely the wildly different clock speeds of the 86 and 96 parts.

    2 - I still want to hear what happens when you drop one of these refresh parts in an older z370 board with an older bios. Do boards that were ok with 8600k refuse to boot a 9600k?
  • ChefJoe - Friday, October 19, 2018 - link

    ack, 9700k-focused at this point. The 9900k overclock part of the review (and presumably 9600k eventually) is still pending.

    My plan was to upgrade from my current i7 6700k to the i7 9700k, and this article seems to confirm that my plan is a decent one. Doubling the core count from 4 to 8 is a decent value. I don't really see the point in paying an extra $100+ just for HT and slightly more cache.

    This release seems a bit tarnished by the fact that it is still the same process node we've had for years now. Addition of cores is great, but it's not without some cost. Still, perhaps we wouldn't even have this improvement if it weren't for AMD's strong return to the enthusiast CPU market. Hopefully the next year will be even more interesting.

    "Addition of cores is great, but it's not without some cost. Still, perhaps we wouldn't even have this improvement if it weren't for AMD's strong return to the enthusiast CPU market."

    It's actually with a LOT of cost. And you should consider whom you're going to reward with your business: the big fat company that milked us for ten years and did everything legal and illegal to crush their competition, or the struggling firm that miraculously came from behind and reignited the market. Make your own choice, but if you buy Intel merely to have the fastest today, you're voting for sad tomorrows.

    Well said, Arbie. Ryzen 2600 (non X) with decent stock cooler for $160 at Newegg = epic win.
  • mapesdhs - Sunday, October 21, 2018 - link

    My next new build will definitely be AMD. Looking forward to it.

    Maybe I am just slow in my upgrading, but my 4770k is still going strong. I am in the market for an upgrade, but I would like to see what sort of difference in performance I can expect. Its nice to see all the latest CPU's on this list, but you don't get a ton of deviation when you have CPU's that are so close in performance. It would interesting to see some benchmarks based on the previous generations top performing CPU's so we can see what sort of performance improvements we would get when moving up from past generations. I feel like a lot of people hang onto their core system components for many generations and it would be beneficial for those people to see these numbers.

    This is a new set of CPU benchmarks and Ian hasn't had time to retest his other 50+ CPUs yet. From prior history that should happen as he has time and will show up as additional data points in bench.

    I don't think you're particularly slow about upgrading. For gaming purposes a high end CPU is reasonable to keep for 6-10 years now; possibly even a bit longer if you're only using a midrange GPU and are willing to accept the higher risk of having to build a new system with zero notice because something dies unexpectedly. I'm in a similar spot with my 4790k; and unless games needing more than 4/8 cores start becoming common am planning to keep it for at least 2 or 3 more years.

    That should hopefully be long enough that Spectre stops generating frequent new exploits and mitigation is fully in hardware, that PCIe4 (or 5), DDR5, and significant numbers of USB-C ports are available. Also possibly out by then, widespread TB3, or DMI being less of a potential bottleneck on intel CPUs (either a major speedup or additional PCIe for SSDs on the CPU). Also by then either Intel should finally have it's manufacturing unfubarred or if not, AMD will likely have captured the single threaded performance crown while holding onto the multi-threaded one meaning I can have both the ST perf that many games still benefit from and the MT perf for my non-gaming uses that can go really wide.

    I'm haswell at 1440p too and the charts have confirmed that I'm holding on for another generation. No sense paying 1500 (32gb RAM) for a platform upgrade to get a few % more frames (and it's fine for my productivity tasks, still faster than new laptops lol)

    I only upgraded from my 4770 to an 8700 because my wife’s i5 4xxx rig died and it gave me an excuse to upgrade my encoding power. I see no difference gaming with a 970. Also I don’t notice increased performance really anywhere except encoding and decompressing during my daily use.
