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.

GN did a great video on this, it's certainly complicated.crimson117 - Thursday, October 5, 2017 - link
Will the included heatsink / cooler be viable on the i7-8700? Or would you still need to buy an aftermarket cooler?AndrewJacksonZA - Thursday, October 5, 2017 - link

Or a used Intel, sooo much value. I'd been looking for a 4930K upgrade for an X79 system (over a 3930K), so as to provide proper PCIe 3.0, etc., main focus is animation, rendering and video processing; gave up, bought a 10-core (20 thread) XEON E5-2680 v2 instead for 165 UKP (very easy to find). It scores 15.44 for CB 11.5, and 1381 for CB R15 (these tests force an all-core Turbo of 3.1GHz), compare these to the 8700K numbers, not bad at all for a board as old as X79, and the temps/power/heat/etc. are excellent.AndrewJacksonZA - Thursday, October 5, 2017 - link
Thank you very much for your efforts, ladies and gentlemen, this was a really informative review and I enjoyed reading it. :-)sonichedgehog360@yahoo.com - Thursday, October 5, 2017 - link

Quiet now, Anandtech only publishes what Intel tells them to publish.Ian Cutress - Saturday, October 7, 2017 - link
Last week I was being called an AMD shill. Before that, an Intel shill, Before that, an AMD shill. Swings, roundabouts, hedges.
