## Description

From the manufacturer

Review: Best I7-8700K CPU Ever! - Love it already and I am surprised how it works out for gaming and recording too I feel so happy with this I rate it 10/10!
Review: Blazingly fast, Super-efficient, great overclocking potential - I bought this along with several other components for a brand new custom desktop. I chose Coffee Lake as it was the newest architecture and I had heard good things about its speed and overclocking potential; also having 6 physical cores is handy! Something to note is that CPU overclocked will outperform the extreme version of it’s predecessor for single core applications (e.g. gaming) but on multicore usage you’d be better off going for the extreme edition as it offers more raw power. I tend to multitask a lot on my PC hence the need for a beefy CPU. Usually running several applications such as CAD software, games, media creation programs, and sometimes even game creation services AT THE SAME TIME is very CPU (and RAM) intensive, so I chose to go with the I7 for the extra power and speed provided. The CPU itself came properly boxed, no heat sink included which I’m glad is the norm now as the stock heat sinks that intel used to provide were never enough! Also, the inclusion of a nice little sticker was good to go on the case 😉 Plugging into the motherboard was simple. Bearing in mind that your motherboard will have to support the 1151 socket for this to fit AND function. I went with a high-end board as to not bottleneck my system (see my other reviews for that item). Running tests, I am very happy. I used the built in overclocking utility in my motherboards BIOS and that managed to easily push it to 4.9Ghz which is better than I expected for automatic overclocking. The system runs stable and damn quick. I ran a Geekbench and Cinebench to test the performance of the CPU and have added the results as images. These results are from AFTER the Meltdown/Spectre mess. Even after the Meltdown and Spectre updates I haven’t noticed too big a slow down to be honest. My desktop keeps up with me well. In fact, I’m glad I went for the fastest model now to compensate for the reduction in speed across all devices. I’m so happy with this purchase, it’s worth the extra cash from an I5. If you need multitasking and speed work your budget around this. I recommend this product. Always happy with Intel. ***If you found this review helpful please don't forget to mark it as helpful below, thanks!***

## Questions & Answers

**Q: why the price of that cpu is so high 400£ compared to 400$ in us(298£ at the time of question)**
A: Multiple answers.

1 - UK products listed post tax, although still more expensive it explains "some" of the gap.
2 - UK business practices tend to focus about making the biggest margin per sale can get away with, USA business practices tend to focus on shifting volume, so they are more willing to accept lower profit per product sold.
3 - UK sells lower volumes, the higher volume you sell, the better deal you can make from suppliers.
4 - There tends to be always "fluff" on the pricing to allow for negative variations in exchange rates which ultimately again means higher pricing.

**Q: What pin count does this processor have?**
A: it Has 1,151 pins, hence the socket name

**Q: can this be installed on a laptop? If not, then where can I buy an i7 8th generation for a laptop?**
A: No, this CPU cannot be installed in a laptop, only a desktop computer with an Intel Z370 chipset motherboard with the LGA 1151 socket. 

You cannot upgrade the CPU in your laptop without changing it's motherboard also. So, not only would you have to get a mobile 8th gen Intel CPU (which isn't available for consumers or commercially at all yet) but you'd also have to get a custom-made motherboard to match the current layout of your laptop (which, again, likely hasn't been made). Even if you could get the CPU and the motherboard for your laptop, this might require re-soldering things the manufacturer soldered down, taking apart the screen and keyboard, stripping it of all the laptop's internals- laptops just aren't made for upgrading and ones that are- you can only usually upgrade the RAM, hard drive, WiFi card and battery but not the CPU, motherboard or GPU.

**Q: I7 8700k coming whit cooling system?**
A: No heatsink or fan included with this CPU

### ⭐⭐⭐⭐⭐ Fast, does not disappoint!
*by C***K on 12 November 2018*

After having an old i3-590 for so long, I decided to finally make the jump to a bigger and better processor- and with all the reviews this thing got, I can firmly say that it does not disappoint whatsoever. Installation proved a little tricky to figure out, but it wasn't really an inherent issue with the product itself, more the motherboard. Upon getting it up and running, the performance of my PC knows no limits, it even turned my GPU into a bottleneck, which amazes me. All in all, this thing is absolutely top quality and very affordable all the same. I'd absolutely recommend it for anyone wanting to make a jump.
