4790K vs. 4790K Devil's Canyon

Recommended Posts

I purchased the 4790K a while back and don't recall it being labeled as  "Devil's Canyon". Is the "Devil's Canyon" a newer version of the processor? Thanks!

4790K is "Devil's Canyon"/Haswell Refresh. 

4770K is normal Haswell.

FYI, Intel's iteration is based on a tick/tock model.

 

More details here:

http://www.intel.com/content/www/us/en/silicon-innovations/intel-tick-tock-model-general.html

 

For example:

Sandy Bridge = tock

Ivy Bridge = tick

Haswell = tock

Devil's Canyon = tock

Broadwell = tick

Skylake = tock

Technically Devil's Canyon isn't the tick, Broadwell is. The tock after that is Skylake.

You're right, I believe Devil's Canyon is actually another tock.

It's neither actually. Intel called it a "refinement" but there are no architectural changes to justify calling it something new. It's still a Haswell.

Devils Canyon is just a Haswell refresh with improved TIM to allow for better thermals on the chip or possibly better overclocking due to improved thermal margin. 

 

Broadwell is the first 14nm chip using the Haswell architecture and Iris Pro 6200 graphics instead of the HD4600 used in Haswell and Devils Canyon.

Ok, so it's more like Haswell/Devil's Canyon = tock

 

Odd that I find people with 4790K's overclocking better than 4770K's, though (after delidding).

Process improvements as well as binning help that.

Devil's Canyon is just a refresh of Haswell, like others said, so it still falls in the same tock cycle of Intel's tick-tock. Broadwell is the tick and the upcoming Skylake is the tock, just like Haswell was the tock to Ivy Bridge's tick. If you already have Haswell, then there's no real need to get Broadwell. Skylake should be the reason to upgrade if you need one.

 

The Haswell Refresh/Devil's Canyon is simply a slight increase in operating frequency, a TDP increase, improved TIM, and VT-d support to non-K CPUs. That's all it really was, so if the packaging said Devil's Canyon or not isn't a big deal. All the 4790s, 4690s, 4590s, and several others. Basically, any that have a name 20 higher than the past (4770 to 4790), it's part of the Haswell Refresh line.

Exactly. Although in my case I get the 4.6Ghz blues!
