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.

Awesome revies! Let's read...prisonerX - Thursday, October 5, 2017 - link
No need, here is a quick summary: "Intel blind panic."StevoLincolnite - Thursday, October 5, 2017 - link
At-least they have finally soundly beat my 3930K in the mainstream after 6 years.Still. No point me upgrading just yet.

Even then there's an interesting option if you want threaded performance; I just upgraded to a XEON E5-2680 v2 (IB-EP) for 165 UKP. Lower 1T speed for sure, but MT should be the same or better as a 3930K @ 4.8. No oc means more stable, less heat/noise/power, and being IB-based means it ups the slots to PCIe 3.0. Not a relevant choice for gaming, but a possibility for those doing VMs, rendering, etc., and just want to get by for a little while longer.Breit - Friday, October 6, 2017 - link
OR search for an XEON E5-1680v2... :)It's an Ivy Bridge-E 8c/16t chip that will fit in Sandy Bridge-E mainboards (x79) and has an unlocked multiplier opposed to this E5-2680v2. So with this you won't lose your overclocking ability.
But in the end, I guess that the greatly reduced power draw and the more "modern" platform from an i7-8700K system compared to the x79 platform will give it the edge here.

Very interesting that the 1680 v2 is unlocked, I didn't know that.Alas though, availability of the 1680 v2 is basically zero, whereas the 2680 v2 is very easy to find, and the cost of 1680 v2s which are available (outside the UK) is extremely high (typical BIN of 600 UKP, normal auction start price of 350 UKP, completed listings only shown for BIN items which were purchased for between 500 and 600 UKP). By contrast, I bought several 2680 v2s for 165 UKP each. Testing on a P9X79 WS (all-core turbo of 3.1) gives a very impressive 15.44 for CB 11.5, and 1381 for CB R15 which is faster than a stock 8700K (for reference, the 1680 v2 scores 1230 for CB R15). Note the following page on AT has a very handy summary of all the turbo bin levels:
https://www.anandtech.com/show/7852/intel-xeon-e52...
So, I'm very pleased with the 2680 v2 purchase, it's faster than my 3930K @ 4.8, runs with very low temps, much lower power draw, hence less heat, less fan noise and since it's not oc'd it'll be solidly reliable (this particular test system will eventually be in an office in India, so power/heat/reliability is critical). For the target systems in question, it's a great solution. Only thing I noticed so far is it didn't like me trying to set a 2133 RAM speed, but it worked ok at 1866; I can probably tighten the timings instead, currently just at 9/11/10/28/2T (GSkill 32GB kit, 8x4GB).
The 4930K I have though will go into my gaming system (R4E), since I don't mind the oc'ing fun, higher noise, etc., but it's not a system I'll use for converting video, for that I have a 6850K.

Full throttle: yes. Panic: no. Blind: no.Zingam - Saturday, October 7, 2017 - link
Can you buy it? No? Paper launch of Unobtanium 8000? -> panic, PR propaganda bullshit and dirty Intel marketing tactics as usual targeted at lamer fanboys.This comment is written by an Intel user! ;)

We've got enough dumb Intel apologists here already, thanks.coolhardware - Sunday, October 8, 2017 - link
The i7-8700 is *finally* going to replace my trusty i5-2500K.Ordered my 8700 on Amazon http://amzn.to/2y9IamG ($319) and looking forward to a nice upgrade :-) That is a lot of CPU for the money IMHO.
Kudos to AMD for bringing competition back to the CPU market!
