Intel i7 4790K Devils Canyon CPU Review

Introduction and Technical Specifications

Published: 13th June 2014 | Source: Intel | Price: TBC | Author: Tom Logan

Introduction

Such has been Intel's dominance of the CPU market in recent years, they've usually held off releasing a new CPU until they are on either a full-scale architecture change, or a reduction in the nm process used. 

The release of the Z97 motherboards had us salivating at what the new Haswell CPUs would bring to the table. However, the model number of this particular CPU, a i7-4790K rather than i7-4770K, indicates that this is a tweak as opposed to a huge adjustment. There is no new architecture. No die shrink. Just an improvement in clock speed and a slight fettling of the thermal interface that dogged the early Haswell processors. 

So with so little that is new to talk about, let's crack straight on.

Technical Specifications

The improvement to the base frequency is one of only two main changes that form part of the i7-4790K. Perhaps that's why it's a small increase in model number, rather than the wholesale step change we normally experience with an Intel processor revision. Otherwise it's business as usual.

Of course when you're talking about the top-end Intel CPU's then business as usual is something we're very happy to have.

Nice review thanks.

If I could get the same 4.80GHZ overclock with a 4970K that I have with my 4770K then I would definitely buy one but I'm not lucky with the silicon lottery Quote

Very nice review Tom. Thank you for the time in trying to enlighten us about the differences from the 4770k cpu. I probably will get one for the Maximus VII Hero rig that I hope to finish in the next couple of months. The 4770k I have now is not a strong one from what I can see. I might get a better entry in the lottery with a new chip. I am also hoping you go back to the VII Hero board with the DC 4790k chip. Your review of that board was what made me buy it on day 1 when it came available. I really hope the combo with the DC chip will be a "Epic Win"

Thank You Again!

Good review as always Tom, the 500MHz boost over the 4770k is nothing to take lightly at stock and the improved thermals is always good.

While it is a shame that the average overclocks for DC is not any higher than vanilla haswell, the improvements are always welcome.Quote

the non K cpu doesn't turbo to 4.4Ghz, only the K one.Quote

Hitman absolutely (heh) loves the overclocked 4790K

I almost lost it with that subtle joke
Great review, and I'm not sure why I don't know this but do you need a z97 mobo for devil's canyon, I currently have an i3 and want to upgrade by the end of the summer (no job makes it hard) so will it be the 4670k or 4690k that I'll be (hopefully) getting?Quote
