i5 8600k vs i7 7700k?

[Nerd]

Building another system for a family member and i'm curious as to which the better option would be for the next 2-3 years.
It will be paired with a 1080 Ti most likely but i've seen mixed results with only a few fps diffference between the 2 cpu's at 1080p.
The system will be meant for playing at 4k or 1440p.
Getting the best possible performance is what matters as money isn't really an issue here, which would be a better buy for playing at higher res?

Feel free to post any other suggestions.

In which case, the x299 7800x might actually make sense, the CPU itself can be had for less than the 8600k, with the cheapest z370 board costing about 120, and the cheapest I'd ever recommend being about 160, the x299 boards start at 200 and are pretty solid,it would get you near 8700k performance with 8 more CPU pcie lanes, the option for quad channel memory (not needed) and probably a bigger future upgrade path in the future as the next enthusiast chips will be on x299 also and probably upto 24 cores lol.

As I said, for once the 'low end' x299 kit makes sense, as a total build it can work out cheaper than the mainstream kit, mind you the big i9's still cost a load right now, but the 6 core 12 thread 7800X is a crazy bargain.

Hyperthreading adds about 30% performance on the 4 core cpu's, while 2 actual cores is a 50% gain to put it at its simplest.

With that said, f you are in Europe, overclockers UK has some crazy good deals on x299 kit right now, 7740x at only £180 (7700k is still £300!), 7640x at only 120 and the 6 core 12 thread 24 pcie lane quad memory supported 7800x at £240, means you can have damn close to 8700k speed way cheaper (£440 with mobo Vs atleast £500), which makes, for the first time, the entry level x299 kit a valid choice purely because f how cheap they can be had at.

When they're used, yes. in current stuff (bar a few exceptions) the 7700k will outperform the 8600k due to HT. Few games even use 4 cores right, let alone 6. Several benchmarks actually show reduced performance when comparing the 8700k to the 7700k due to the former being clocked lower.

When we have such crap ports from toasters that are struggling for 900p/30, no developer is going to optimise for 6 cores unless they know what they're doing in the 1st place.

When clocked equally they perform pretty much the same, and real cores perform better than hyper threading, 4 virtual cores add about 30% performance when hyperthreading is supported, in the same occasions hyperthreading is supported, there is a very high chance the extra cores can be utilized as they are treated the same pretty much.

tell that to ubisoft lol. Seriously though, I've seen a lot of performance tests in my time where HT has made a good difference whilst more cores does not.

A good recent example is Assasin's Creed Origins. The game performs identically whether you use a 4 core or 6 core cpu.

Hell we have games that don't even launch if you set your audio frequency above 48khz...

Late 2017 New AAA games are now Using full 6 cores. Also full utilization of Hyper Threading.
in Games like Assassin's creed origins / Wolfenstine 2, an i7 is solid 30% faster than same Gen i5 due to its HT. And also i7 8700k is much faster than i7 7700k due to 2 extra cores. Even Ryzen7 is beating 7700k, Which never happened before. see below-

Since both intel & AMD is now going 6+ Cores.
Game developers are now waking up.........

well due to longevity (was the idea anyway) my 7700k and 1080 are only for 1080p/60 lol.

[Monk]

I'm stuck with a 5GHz 10 core so I have to put up with the best of both worlds, clock speed with core count, life sucks ... Hehe.
But seriously check out the discounts on entry x299 it's crazy good value compared to mainstream oddly.

is the 7700k going to be a problem at 1080p/60 though? really couldn't afford to upgrade for a good few years i think.

for 1080p@60 fps? Jeez that's enough power for the next x years.
You could even run 1440p/144.

But ya, u will not rly run into any probs with your setup.
I'm running a 1440p/144hz screen (sometimes my 4k envy) with 6600k and a 1080 strix without probs, so ya u are fine as eff.

It won't and nobody will call the police or so for running an i7k @ stock.

I would overclock it, but i've had some games act weird just using the xmp profile on the ram...

note to self: stop buying japanese ports...

i5 8600k it kicks the 7700ks butt, don't bother with last years tech.

7700k is from this year..

[hawkeye]

If money is no objection then the 8700k. It plays cpu intensive games faster than anything else due to its #1 ranking in single thread speed. It's also the least risk option. It's going to have even better performance differential when faster gpus become available.
