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.

In speech: "grateful" to AMD for reinvigorating competitionIn deed: gives money to Intel, effectively taking part in keeping AMD down for that bit longer, maybe causing them to return to non-competitive state, upon which AMD is blamed for being non-competitive once more.
The Invisible Hand doesn't seem so wise, sometimes.

AMD did a fantastic job with Ryzen while Intel were busy milking their customers dry. We should support AMD when they need us most. If AMD goes down it would suck not for the industry but technology as a whole.leexgx - Monday, October 16, 2017 - link
at least you can enable MCE to make all cores run at 4.6Ghz (make sure you got a good cooler) 8700K would allow you to goto 4.9-5.1Ghz with very good coolinglordken - Saturday, October 28, 2017 - link
what a "brilliant" asshardware , your Kudos worth shit to amd as they cant fund further r&d with it. But sure, run to support your milking master because they finally bothered to release, after 10 years, 4+ core for mainstream...Budburnicus - Wednesday, November 1, 2017 - link
Salty salty salty people! AMD are big boys too, they can fight for themselves. It is called a FREE MARKET, and until Ryzen, AMD had nothing to even come within spitting distance of an i7-2600k!Which is coincidentally what I upgraded to my 8700k from. Running 4.8 GHZ on all cores for now, I still have plenty of thermal room, so once more people have figured out all the minute settings, I will just leave it at 4.8 til then!

Thas me, ahead of 96% of all results! And that single threaded perf, is totally insane - as is multi-core, nothing short of 16+ threads can touch it.

I like how Ryzen 5 1600 beats the much higher TDP and much higher priced Coffee Lake in Civ Vl.This should ring a bell how software is written!!!

...cherry pick one benchmark, claim that it's the only one that matters...*cough*AMD fanboy*cough*

I don't own anything AMD!Drink some water and stop that coughing!
