10% of the time, video editing [at most]. Even then, I'm not time restricted.

What GPU & Resolution you going to use?
If you use a GTX2080Ti at 1080p then, I could see the merit of the 8700K @ 5Ghz overclock if you want to have couple of fps more.

Otherwise there is absolutely not a single reason not to buy the 2700X.

have a look here. A very comprehensive overclocked review.

https://www.techspot.com/amp/review/1655-core-i7-8700k-vs-ryzen-7-2700x/

browse through the game.
As you see at 4K the difference going to be 0
Already is at 2560x1440..... And barely couple FPS at 1080p.

So a 2700X is cheaper (almost £200 at this moment), which will allow you to buy better GPU, while overall is a better platform as with an M.2 drive isn't going to be bottlenecked with PCI-e lanes.
8700K has 16 pci-e 3.0 lanes all dedicated to GPU and everything else communicates over the equivelent of 8 pci-e lanes.
2700X has 24 lanes. 16 for GPU, 8 for M.2 and a connector of 8pci-e lanes to the chipset to share with everything else.

If using emulation a lot then this chart might be worth a look https://docs.google.com/spreadsheet...suONtRCte51GHKdgA7ciL76mBs/edit#gid=485052351

TLDR; Ryzen is nowhere near in dolphin.

The 2700x just can't keep up with the clock speed advantage in single threaded apps, especially when both are tweaked. My 8086k runs at 5Ghz all day long in a laptop.

£4,000 laptop I'd hope it would

Most of that cost is in the GPUs (1080 SLI) and 1TB SSD to be fair

Either way the size of my heatsink is still tiny compared to the likes of a desktop tower.

Might seem shocking to some how close the 2700X is to the 8700K. Only 7% behind at worst case (1080p res) and that's using a 1080 Ti. If you have cards slower than that then the tiny gap goes down and down. When you go up with res, the CPUs are neck and neck.

Overclocking doesn't help the 8700K much either, as according to TPU again, 5Ghz overclock adds only 1-3% performance (this is in the review summary).

So in summary the 2700X is the best high-end CPU on the market currently on a platform that will let you drop in a 7nm Ryzen CPU next year should you need to. The only upgrade path for the 9900K is possibly yet another 14nm+++++ refresh but there is no room for higher clocks on that old process so I'm not sure if they'll bother. As a 14nm CPU that is essentially a Skylake refresh when 7nm Ryzen 2 is on the market is a terrible proposition.

On the link posted above, which is pretty thorough tbh, it states. 8700K @5ghz is less than 9% faster than the 2700X @ 4.2ghz at 1080p, while consuming 10% more power than the AMD CPU.

Yes. I will be interested to see how power hungry the 9900K will be, with it's extra 2-cores and extra 300Mhz max boost clock (4.7Ghz vs 5Ghz). It's gonna drink power like no tomorrow on any all-core overclocks past 4.2-4.5Ghz range, and require the very best AIO cooler or custom loop to tame. All for what, less than 10% more gaming performance, and only at 1080p resolution? Won't be worth the £300 premium on top of the price of a 2700X for sure.

Actually you can buy a 2700 at £257 which can do all core 4.2Ghz..... Making the difference £343 :eek:

Well slap my arse and call me Shirley. That's even worse and verging on the insane for anyone to opt for one above a 2700/X. Have Intel got people by the balls so hard that they think they can get away with these ludicrous prices?? God help us all.

They are trying to balance the books and keep the shareholders happy. They can't be seen to be losing.

Have you seen the new HEDT lineup? Completely ignores that AMD Threadripper exists!!!!!!!
Seems same applies to the mainstream. Cannot explain it otherwise.

Their's always numpties willing to pay these prices that make it hard for the rest of us. But I think the days of Intel being able to get away with this pricing are very numbered because of Ryzen. Wait until 7nm next year for true marketshare decline for Intel.

Damn, now I'm pondering whether to get a 2700X or not. Its £300. The 8086k is £390 although i think i can get another 20 or 30 quid knocked off to make it £360.

This is what I've heard! People keep telling me its outdated and Ryzen is amazing for emulation now...

When I had my 1700 it was getting destroyed in CEMU by a 7700k

The 2700X has gone down to £290 now on OCUK. That should be your decision made for you right there. Better buying that or a cheap 2600 as you get the option to drop in a 7nm 3700X next year that will surely be the fastest CPU on the market.

Cemu and a few of the other still favour intel

Speaking of which I'm an Intel Fanboy but these prices I'm seriously thinking of going AMD, I'm completely clueless when it comes to AMD, I "assume" the memory/power supply/AIO cooler and ram in my current rig DDR4 etc will just swap over?

Yeah. Does your aio has am4 bracket? Last year many companies gave them for free.

Maybe I would have to check it's a corsair h110 thingy.
