I5 8600k or I7 7700k

[wellhillo]

Hey

Since my Prime z270-A broken, the store replaced it with a ROG STRIX z370-G. I was told my I7 7700k would work fine with the z370 chipset.
Here in Denmark, I can sell the I7 7700k for almost the same price as a new I5 8600k.

My question is, would it be a downgrade in performance to sell my I7 7700k and buy an I5 8600k?

i7-7700k will not work on Z370 motherboard.

i7-7700k is 4core/8thread cpu, i5-8600k is 6core/6thread cpu.
It's hard to tell, which one will be better in your situation. It depends on workload. They are quite similar.
I wouldn't call it a downgrade - more like side-grade.

I thought as much, according to the ASUS website only 8th gen cpu’s are supported so the 7700k won’t work.

The 8600k and 7700k are very closely matched. I would say overall the 8600k is very slightly ahead.

The store told you that 7700k should work with Z370?
I wonder, if he/she is qualified to sell and build those stuffs.

Make him do the installation!
If he broke anything or if something does not work (it will not work), make him pay for everything!

Above is correct, so let me be specific:

1) i7-7700K is 4-core with hyperthreading. That (roughly) is like having x4 extra cores that are about 30% as powerful as the main cores.

2) i5-8600K is 6-core without hyperthreading. Each core with overclocking is slightly FASTER than each of the i7-7700K's cores.

3) very few games or applications will see a difference as very few can use more than what the i7-7700K can offer

4) the i5-8600K is better in every way (again whether you see a difference or not) and I would say absolute best-case advantage assuming max overclocks on both, and near full utilization of every THREAD (true core or hyperthreading of core) is 20% in favor of the i5-8600K.

5) I saw a CINEBENCH MULTI-THREADED (all/most CPU threads) test where BOTH CPU's were overclocked and it showed a 14% advantage to the i5-8600K

Other:
The OVERCLOCKING potential depends on the CPU cooler. The requirements for the cooler grow much higher as the frequency increases (it's the VOLTAGE that matters) thus 5GHz is far too much for medium/low coolers though 4.6GHz all cores may be obtainable especially with optimized settings in the BIOS.

The NH-D15S is an amazing cooler that can handle 5GHz on the i5-8600K at 80degC (assuming same setup and conditions. case cooling, BIOS settings and ambient room temp all are big factors too).

Lesser coolers can still do a great job and practically speaking 4.6GHz all cores for 98% of the games is identical to 5GHz all cores anyway.

8600k, no question. It's the better processor and outperforms all Ryzen processors as well. It's about 10% better than 7700k and on a newer platform. If you already have a Z370 motherboard then it's an even better idea.

8600K all day long, however the motherboards on Z370 are more expensive, than Z270. I guess if you weren't satisfied down the line, you could upgrade to the 8700k later down the line and sell the 8600k, whereas the 7700k is the end of the line for the Kabylake series. Sure the Ryzen series isnt as fast IPC as Intel, but with more cores if talking Ryzen 7 or even Threadripper, which seriously performs well. It depends on your budget. For most things programs have just started using 4 cores, and you can use Utility programs till the cows come home to show more cores are better, however you should check how many cores your program actually uses, whether it uses hyper-threading or not. Then make a decision.

never buy anything from that store again:
1. you can force them to give you equivalent z270 board.
2. since for some reason they gave you better board that you had and it will cost you almost nothing to change to i5-8600K just do it.
6 real cores are better than 4 hyper threaded. and if you into overclocking, 8600K will do wonders.

the 8600K is a gaming beast....

Sell the 7700K, get the 8600K, you win.
