Core i7-8700K 3.7GHz (Coffee Lake) Socket LGA1151 Processor - Retail

Intel Coffee Lake brings you more cores for similar money to the last generation, getting you more performance for you money, particular in multi-threaded applications.

In testing we have found overclockability pretty promising on the Coffee Lake series, of course on K series products only and we shall be offering 8 Pack pre-binned processors from launch on 8700K.

This is a retail boxed processor and comes with Intel 3yr warranty and is un-opened and brand new, so your overclocking mileage is down to yourself and luck of the draw but coffeelake promises to push the envelope the furthest yet when it comes to frequencies making them ideal for games and applications that require outright pure MHz performance and they still have incredible multi core performance as well.

- Lithography Process: 14 nm
- Cores: 6
- Threads: 12
- Frequency: 3.70 GHz (Turbo Mode 4.70GHz)
- Cache: 12MB
- Memory Controller: Dual channel DDR4 2400/2666/3000/3200/3600/4000/4133/4266/4500/4600/5000+ MHz- Socket: LGA1151
- Memory compatibility: All DDR4 is compatible (Check your motherboards manual and we recommend 8 Pack 3200MHz and faster kits which guarantee Samsung B die for upto 5000MHz OC)
- TDP: 95W
- 3yr Warranty

Superb cpu i have been waiting for the coffee lake upgrade for a while now and it is worth it, its running at 4.7ghz with ram at 4ghz on xmp without a hitch although i had to wait for the new bios for my board to get it to work properly, i am using an all in one water cooler from nzxt and the cam software shows the cpu temp which appears to cool very quickly after gaming, escape from tarkov runs really well, well chuffed....

amazing speed :) Just a shame the prices are over the RRP

Fantastic CPU and a lot faster than my i5 2500k 4.5GHZ - Sony Vegas 4k files take a matter of min instead 15 or 20 mins. so well impressed , Games just fly with this CPU. running PUGB on ultra at 1440p well over 90 FPS with 1080ti

A fantastic all-round CPU

I upgraded from an i5 4690k at 4.4ghz with some trepidation but I am glad that I did. General system performance and responsiveness is so much sharper, everything loads incredibly fast as soon as you get into windows.

I got mine to 5ghz at 1.295v on air with a NH-D15 (and a ton of case fans) which I'm pretty chuffed with.

Gaming performance with a GTX 1080 is improved in all areas (some more than others), but in certain games like GTA 5 the difference is incredible - the game runs so much smoother on the 8700k with no dips in frame rate which my i5 4690k suffered from.

All in all, I would definitely recommend the i7 8700k to anyone who is sitting on a 4 core/4 thread i5(especially haswell or older)

For those sitting on an i7, it may be worth waiting for ice lake unless you have a GTX 1080 or better and want to get the most out of a high refresh monitor.

Asus ROG MAXIMUS IX HERO,Intel Z270,S-1151,

hi , work new cpu 8700k for my motherboard , Asus ROG MAXIMUS IX HERO,Intel Z270,S-1151, ??? thanks

Pure Speed, Pure Threads!

I've overclocked mine to 5200mhz @ 1.350v which beats the Ryzen 1800X 8 core on both single and multi threaded apps comfortably!! And its only a 6 core! Fastest most insane CPU I've ever owned. I thought my 7700K was fast but this is on another level. I've even got my CPU cache overclocked and stable at 5000mhz (-2 offset for stability). Couldn't recommend it enough
