i7 4790K vs. i7 5775C

[Tytan64]

Hello, everyone!

I have an ASUS Z97-P motherboard and an Intel Core i5 4690K.

Can you tell me the difference between the Intel Core i7 4790K and the Intel Core i7 5775C, so I know what to upgrade to if I want to?

This is not a trolling post. I really don't know which is good for what ^^;

I mainly game on my system. I'm also a Linux and BSD administrator. So no rendering and stuff.

Thanks for sharing your knowledge!

4790k is your standard Haswell Refresh CPU

5775c is broadwell, 14nm and runs cooler. Also, it has L4 cache (basically) when the much superior iGPU isn't being used.

 

Both are overclockable. I'd love to have a 5775c

So can you say the i7 5775C is superior to the i7 4790K?

Maybe one is better for gaming than the other...

5775C has better integrated graphics and consumes a little less power. It is clocked a lot lower than 4790k and is a little bit slower. But it is more expensive.

So basicaly there is no reason why you should look at 5775C on desktop.

Once overclocked, the 5775c and the 4790k do trade blows.

But can the 5775c hit 4.8ghz ?

[Tytan64]

Since it "only" has a base clock of about 3.2GHz I don't think so.

No, but it can perform just as well as a 4790k clocked at that speed at a lower frequency because of said L4 cache.

Depends. You have to OC 5775c a lot more to catch up with 4790k so it comes down to silicon lottery and it is about luck then. Also 5775c requieres a lot more voltage than 4790k.

4790k - 4.4GHz

5775c - 3.7GHz

 

The IPC of 5775c is barely any better so you have to get it to at least 4.2GHz - 4.3GHz in order to match non overclocked 4790k in terms of CPU performance.

 

L4 cache helps iGPU quite a bit .. not so much for the CPU part so it doesent matter that much. Comes down to what application you are going to use.

Also 5775c is not known as a good overclocking CPU so even hitting 4.3GHz may be challenge.

4970K is better as a CPU!

[Cvdasfg]

as just a cpu 4790k is better. Cpu/gpu then the 5775c is better

I guess I take the 4790K for gaming and the i7 5775C if it's "just" a Linux based desktop where I don't use my GTX 980 Ti then

Yep!
