Core i7-4790K or Core i7-5775C?

[Hi-Fi Man]

I'm thinking about upgrading from my current CPU (in sig below) to keep me future proof a little longer for games and to have a bit more multi threaded performance. The problem is I have two choices, the i7-5775C and the i7-4790K.

According to a few benches the i7-5775C seems to be really good for games due to it's 128MiB L4 eDRAM cache, so good in fact that according to The Tech Report it surpasses the i7-6700K or at least equals it in games at stock clocks. I will be overclocking the CPU and I realize the i7-5775C doesn't seem to OC well (~4.2GHz max) but I don't know if I'll be able to OC the i7-4790K that high either due to my board. If anybody has overclocked an i7-4790K on a 3+1 phase please let me know what you got.

The price premium for the i7-5775C is not a big deal for me especially considering it's resale value will probably be higher due to it's rarity.

Be sure to check if Broadwell-K works with you motherboard first. Regarding the question, I'd go with Core i7-5775C. Generally performs better than Core i7-4790K at stock while using less power, and once OCed to 4GHz it's probably out of reach even for a highly overclock Haswell.

5775c.

It just doesn't seem like either chip would be a big enough jump from your 4690K.

This is partly true, however I have the upgrade itch and I usually stay with a platform and CPU for a long time so I want to future proof myself as much as possible.

Just purchased the i7-5775C and I'll post some benches when I get it! Might get a new board to really see what this chip can do...

Great choice, keep us updated.

I *don't* recommend the 5775C unless you're going to take advantage of the very nice Iris onboard graphics. I think the overclocking of the 4790k would be better.

If the price difference doesn't matter to you, sell the old 1150 mobo and whatever cpu you have now and just get a full 1151 i7-6700k combo so you have the very latest platform and all its benefits.

My two cents.

[edit] Oops... you already purchased. Well, it's a great chip and you can turn it into a fantastic tiny-sized ITX media/light-gaming machine later!

Intel should have released a higher wattage enthusiast-aimed Broadwell with Iris disabled (to increase yields) and high-quality TIM instead of releasing Skylake.

Then, Skylake on the desktop should have had EDRAM as Kaby Lake will likely have. Skylake has the EDRAM controller but no EDRAM.
