4770k vs 4790k

So I am building a new computer soon, and I am trying to decide weather to get the i7 4770k or the 4790k, because the 4770k is more expensive (on amazon, anyway, which is where I am buying everything for the build) but the 4790k is the "newer and better" processor. So my question is, if they are clocked at the same speed, say 4.5 GHz, is there any difference between them big enough for the $10ish more for the 4770k.


Thanks for your help in advance.

 

The 4790k has better power delivery and better TIM, if you don't intend to do extreme overclocking and have a good cooling solution, the 4770k performs just the same and is cheaper.

But why don't you just use your i5 4690k? The i7 won't perform any better in games, only in applications that use more than four threads, which are few and far between.

 

4790K has thermal interface between the CPU die and the IHS, while the 4770K is soldered.
To put it in simpler words, the 4770K will run slightly cooler, but the 4790K can be delidded, while attempting to delid the 4770K will break the die.

4790K also has higher stock clocks, although if you're overclocking that's not too important.

However, if this is just a gaming build and no video editing or rendering is intended, I strongly recommend just going for an i5-4690K. Great CPU, matches the i7 in single thread performance clock for clock, and hyperthreading is completely worthless for gaming.

I forgot to mention, but I plan to edit. Also, my friend has a stock 4790k and he out performs me, he has all the same parts accepte he does not have a water cooler.

 

Wait, if you have a 4690K, why would you even upgrade? Not worth the money. Spend it on a better GPU instead, go for a GTX 970 or R9 290X instead of an R9 280.

The only game where HT can actually make a difference is BeamNG, or anything equally CPU intensive. Anything else won't get much out of an i7, 3-4 fps at most.

 

The hyper threading actually helps, as shown by my friend (at least in this game) he has a 4790k at stock clocks, but he can run more vehicles than me even whith the lower clock due, as I would expect, to the hyper threading.

 

See above. In BeamNG, hyperthreading does help have more vehicles without slowing down. However, I'm assuming you play something else as well, in which case a better GPU is a smarter choice. Although if you feel like throwing $300 in for a single game, go for it, nothing stopping you.

 

When I build this new computer, I have other parts in mind, for example, I am getting a new motherboard, cpu, and a gtx 980/970 (not sure yet)

 

I realy am sorry I am forgetting stuff all over the place, but I also record videos, so the hyperthreading will help with that.

 

As long as you are at 1080p, the 970 will be fine for gaming. If you can record on your CPU instead of GPU which I think is possible, again the 970 will be sufficient. However, if you are going to be recording with the GPUs, you might have to sacrifice some settings but the 970 will be fine. If you are recording with the GPUs and not willing to sacrifice any settings then maybe a 970 SLI setup will be best. Much more power than a single 980 but only a bit more money. With your question about the CPU, which ever is cheaper.

 

The GTX 970 has Shadowplay, you can record video with nearly no performance impact at all (2-3 fps at most).
