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.

Should be sorted now. Found a small issue, pages should be loading in sub 2 seconds.anubis44 - Monday, October 9, 2017 - link
"Not sure why there is no R5 1600 in the test though. It will be good to see how the 6 cores solution compete."It's essentially as you'd expect. In older, single-threaded code, the Intel CPU has a slight advantage, but in any newer, multi-threaded code, the Ryzen 5 1600's hyperthreading 6 cores will dominate. It's time to stop giving Intel money for fewer cores. They don't deserve the cash. Give it to AMD for a change, now that they're genuinely competitive.

Annnd stock is unpossible to find...Complete paper launch.

Newegg seems to be accepting orders.rtho782 - Thursday, October 5, 2017 - link
I'm british! :POcUK put all their allocation (30 pcs) into binned delidded cpus at £499/£599/£799
The others are all gone.

8700k is in backorder there. And for the rest of the world?I can get a 8400 in my country. 8700k seems to come 2 dec.
I cant remember anything similar for the last 3 decades. Perhaps the P3-1000.
If this is not a paper launch nothing is.

If you want a P3-1000 I have one I can sell you! Fully working with motherboard. LOL. I think it also has a whopping 256MB RAM.watzupken - Thursday, October 5, 2017 - link
I think I read somewhere that mentioned that supply will be limited, especially at the start.mapesdhs - Friday, October 6, 2017 - link
Gotta love the way searching on Amazon for 8700K brings back the 7700K (as opposed to simply, Not Found). By grud their search engine is bad. :DFourEyedGeek - Saturday, October 7, 2017 - link
Bad for them?
