Benchmarking Performance: CPU Web Tests
One of the issues when running web-based tests is the nature of modern browsers to automatically install updates. This means any sustained period of benchmarking will invariably fall foul of the 'it's updated beyond the state of comparison' rule, especially when browsers will update if you give them half a second to think about it. Despite this, we were able to find a series of commands to create an un-updatable version of Chrome 56 for our 2017 test suite. While this means we might not be on the bleeding edge of the latest browser, it makes the scores between CPUs comparable.
All of our benchmark results can also be found in our benchmark engine, Bench.
SunSpider 1.0.2: link
The oldest web-based benchmark in this portion of our test is SunSpider. This is a very basic javascript algorithm tool, and ends up being more a measure of IPC and latency than anything else, with most high-performance CPUs scoring around about the same. The basic test is looped 10 times and the average taken. We run the basic test 4 times.
Mozilla Kraken 1.1: link
Kraken is another Javascript based benchmark, using the same test harness as SunSpider, but focusing on more stringent real-world use cases and libraries, such as audio processing and image filters. Again, the basic test is looped ten times, and we run the basic test four times.
Google Octane 2.0: link
Along with Mozilla, as Google is a major browser developer, having peak JS performance is typically a critical asset when comparing against the other OS developers. In the same way that SunSpider is a very early JS benchmark, and Kraken is a bit newer, Octane aims to be more relevant to real workloads, especially in power constrained devices such as smartphones and tablets.
WebXPRT 2015: link
While the previous three benchmarks do calculations in the background and represent a score, WebXPRT is designed to be a better interpretation of visual workloads that a professional user might have, such as browser based applications, graphing, image editing, sort/analysis, scientific analysis and financial tools.

I'm not sure. :D It's certainly annoying though. Worst part is searching for anything and then changing the list order to cheapest first, what a mess...SunnyNW - Thursday, October 5, 2017 - link
"That changes today."Anyone else read that and think that it is something we should have been reading ages ago?
Consumer technology is progressing slower than many expected and I feel the same way. Nonetheless I can't help but envision a Very near future where I'll be coming back and reading this article and being depressed at this level of technology all the while on my future monolithic many thousand core 3D processor ;)

Yes. A year ago this would have been an exciting development. Now it's just Intel remaining competitive against AMD's offerings.Valcoma - Thursday, October 5, 2017 - link
"The Core i5-8400 ($182) and Core i3-8350K ($169) sit near the Ryzen 5 1500X ($189) and the Ryzen 5 1400 ($169) respectively. Both the AMD parts are six cores and twelve threads, up against the 6C/6T Core i5 and the 4C/4T Core i3. The difference between the Ryzen 4 1400 and the Core i3-8350K would be interesting, given the extreme thread deficit between the two."Those AMD parts are 4 cores, 8 threads.

You're right, had a brain spasm while writing that bit. Updated.kpb321 - Thursday, October 5, 2017 - link
Still off"The difference between the Ryzen 5 1500X and the Core i3-8350K would be interesting, given the extreme thread deficit (12 threads vs 4) between the two."
the 1500X is a 4c8t processor so it effectively has hyper-threading over the i3-8350K while having a lower overclocking ceiling and lower ipc.

Ian, I love the way the gaming benchmarks are listed. So easy to access and much less confusing than drop-downs or arrows. Nice job!Valcoma - Thursday, October 5, 2017 - link
Are you sure that the i5-7400 got 131 FPS average in benchmark 1 - Spine of the Mountain in Rise of the Tomb Raider? Besting all the other vastly superior processors?Looks like a typing error there or something went wrong with your benchmark (lower settings for example on that run).

I've mentioned it in several reviews in the past: RoTR stage 1 is heavily optimized for quad core. Check our Bench results - the top eight CPUs are all 4C/4T. The minute you add threads, the results plummet.https://www.anandtech.com/bench/CPU/1827
