i5 or i7

What are the differences between an i5 4690k and an i7 4790k?

Basically Hyperthreading, which offers gains for things like video / photo editing, streaming, rendering, etc. Although in my experience if youre not doing anything too heavy, the i5 works great.

Hyperthreading, which is not really needed for gaming. So if you're building a gaming computer go i5, if you'll need the extra threads go i7.

Basically, higher factory clocks (although OCing and the silicon lottery can mititgate that), Hyperthreading (already explained above), and bigger l3 cache (which is irrelevant, unless running SUPER-INTENSIVE memory apps).

Hyperthreading is the only difference. If the PC is mainly for gaming, save yourself that cash and go with an i5/ put that cash towards other parts of the system.

 

There are other more technical details like cache, but you won't notice a difference between the 2 in gaming...

If you do a lot of multitasking the i7 will be better. Also the i7 will help with almost everything that isn't gaming.

 

If you just plan on gaming go with the i5. If you don't mind spending the extra money to have a bigger e-peen, get the i7.

The 4790k has hyperthreading and is better binned. By better binned I mean it's binned to run at 4 GHz on all cores at the 88W power target. A 4690k might need higher voltage to run at the same speed, as it's only guaranteed to hit 3.5 GHz at the 84W target. I'd personally grab the 4790k since right now it seems like CPUs are good long term investments (e.g. 4-5 years). They're both extremely strong gaming CPUs though.

With that said though, if getting the i7 would make you drop your GPU to something lower than an R9 390, get the i5 and the 390. Crysis 3 is the only game I know of right now where you'll ever be held below 60 fps by an i5 vs an i7, and that's only in the Welcome to the Jungle section if you run on the Very High preset. Hyperthreading does give more performance in some games, but none of these games aside from Crysis 3 are struggling on an i5.
