Intel Core i7 4790 

Released May, 2014
  • 3.6 GHz
  • Quad core
9 Out of 10

Combined with the slew of new Z97 motherboards that have hit the market; this paired with a nice high-end single GPU Video Card from AMD or NVIDIA is going to make for a truly wonderful gaming system.

Benchmarks clearly showed the advantage of the Devil's Canyon CPU and it range from 7-15% depending on the application and the threaded efficiency of the application.

In The News From around the web

The Core i7-4790 that you've got is plenty powerful at stock clocks, but is it worth upgrading your cooling and motherboard?
I'm going to open this up to our readers though, as they'll provide you with some great insight into various games and whether they're CPU limited - as well as providing you with some advice on whether you should indeed, overclock that Core i7-4790.
Our tests show that the total amount of power needed to hit any given frequency, however, has only improved slightly.
Looking around online, I found one chip from XtremeSystems that was capable of hitting Intel’s 5GHz on air claim, though it was running at a much lower operating voltage at 4.6GHz than my own CPU (1.25V vs. 1.35V).

Intel Core i7 4790K (Devil's Canyon) CPU Review

by Shawn Baker |
Overclocking does indeed cause a spike in temperature and a little more than we'd like considering that we're a good 200MHz+ lower in clock speed compared to our 4770K when it was running at its max overclock.
While overclocking doesn't affect our overall Lightroom time much; you can see out of the box the Intel i7 4790K does an excellent job.
Impressive out of the box performance aside, the other big mystery is how much the new thermal interface and capacitors on Devil's Canyon would change the way Haswell overclocks.
Seeing a couple of degrees improvement in load temperature with an increased clock speed is a welcome change and can be attributed to the improvements Intel designed into Devil's Canyon.

I mean this a Haswell Refresh version and I thought that they fix it?
TSX enterprise bug exist in Core i7 4790?
$185!!! yeah right!! does value score influence on overall score? if it is true, it will bring down a lot of Intel CPUs scores
Two months later and the prices on this site is still not fixed. Aren't they surprised that nobody is purchasing Haswell with their affiliate links?
Fix the prices on the haswell refresh CPUs plz.
