i7 i7-8700k vs. i7-7700k vs. i7-7740x

[Adm_Dolphin]

I am currently looking into buy some new components and I am curious as to which one would be better for me, I do alot of gaming a little bit of streaming and a lot of multi tasking. I have narrowed down my option to

i7-7700k, it is a a name stay for gaming being a quad core and performance looks good and heard good things about it

i7-7740x due to the higher clock speed over the 7700 and the price tag being only $60 more, and the same price as the 8700, it is a stong option for me

i7-8700k has a slower clock speed over the 7740 but it has an extra core for the same price.

due to bad experience with AMD I will not consider them but for the CPU's which one would be better for my needs?

Out of those, the 8700k is the best. As for the 7740X, it shouldn't exist, and the 7700k is going to slow down over time as games become more multithreaded.

The best value CPU for high end gaming is the locked i7 8700 because it has every thing, high frequency, 6 cores with hyper-threading and opposed to the i7 8700k you can cheap up on motherboard and cooling since it only has 65w of TDP, they perform identically when the k is at stock.

 

out of these 3 options the worse is the i7 7740x because it uses Mesh.

Yeah AMD, is causing a shift towards multithreaded performance, so I would go with that CPU.

8700K if you're overclocking. 8700 if not. the 7740X shouldn't even be around, idk what Intel was thinking.

The execs all had this strange eye infection that impeded common sense.

I'd go for the Ryzen 1700

The 7740x does not use mesh core connectivity. Its a higher clocked 7700k on a bigger die.

Would there be any performance difference between a quad core and hexa core CPU in gaming? If we talk about the same CPU of course.

Depends the game, one thing should taken into account as well, while 4 cores usage is becoming the norm for all games, you can't forget about your system needed resources as well, if 4 cores are being used by the game already you might have slow downs whenever Windows or background stuff needs to do something at the same time you're gaming.

 

So even if the game can't take benefit from 6 cores in its code you'll still see benefit from having it and when you do come across a game that is well coded to take advantage of more than 4 cores beauty happens:

 

i7 7700k = 159fps / i7 8700k = 200fps

This is very interesting but like you said it depends on the game. In conclusion i would say: 4 cores = sweet spot and 6 cores = future proof

I already made a thread exactly about this and got told it will take a few years before games use these extra cores.
