Intel Haswell Refresh Processors Codenamed Devil’s Canyon – Launching in Mid 2014 With Unlocked Desi

Temps don't really matter as long your not running it at 90degC. Pretty sure DC actually has a slightly higher power consumption than Haswell.

Agreed, temps are so much better than the current chips. If mine matches the clockspeed of my current 4770k ill be happy enough as a temp drop is what im after.

+1 for lower temps

Agreed.

If someone is only interested in running at 4.5, and temps are in 80s, then there no point in moving on. Just live with the temps.

If temps are limiting an oc, then that is another matter.

lol temps are better so it's worth it? nope.

wazza300 · 13 Jun 2014 at 22:34

put your 4770k's in a vice,hit it with a big dirty hammer and voila you have a devils canyon cpu

Tonester0011 · 13 Jun 2014 at 22:44

I'll probably buy 5 chips. I want at least 5g for benchmarks if I don't get one will throw my toys out, strip and sell my computer then wait for x99 lol.

At 4.5 here but temps can get very high, id like to push this chip higher but its already quite volt hungry and anymore would just increase the temps way too far.

It is if you can stick the chip your replacing on the market to get a chunk of the money back, I keep all my boxes so I can repackage it and sell it on as in very good condition.

After watching TTL's review and reading some others, got my interest back in this 4790K chip.

Basically if you run it at stock it's 4.4Ghz turbo is sustainable with decent cooling. Gives about 17% performance increase over 4770K (Stock VS Stock) as my 4770K gets about as hot as a thousand suns even mildly overclocked, I may still consider grabbing a 4790K and just run it at stock, enjoy the extra stable speed and lower temps.

setter · 14 Jun 2014 at 12:21

Indeed, the stock turbo boost is pretty decent. From what ive seen on here and other forums, many 4770k's are struggling to hit this with insane vcore and then factor in the ludicrously high temps that come with this. Ill fire up a few comparison shots when i get mine installed. At stock speed my 4770k gets to 77c max under p95 small fft. Obviously it wont be the best comparison due to the 4790k's higher turbo clock.

It might not be a life changing upgrade for those who already caved in on buying 4770K but for everyone else looking to upgrade from lesser chips the 4790K is better in every department.

Same price.
Higher clock.
Lower temps.
Vt-d (supposedly?)

It would have been easy for Intel to just release the 4790K with bog standard paste/silicone clocked at 3.6/4ghz if they had just wanted to make a quick buck.

eddyr · 14 Jun 2014 at 13:58

The TIM improvements are probably a result of needing something better for their upcoming 14nm chips. That's my suspicion. Easy to chuck it onto an existing product for marketing/testing.

setter · 14 Jun 2014 at 14:00

Apparently the ihs is much thinner as well, and maybe less glue used.

Unless CPU-Z need updated they have same Instructions.

What was TTL saying about the Voltage Controller was supposed to be going back on the Mobo (reason DC was not to work in Z87), as that would be back to the old days before it was moved off the Mobo onto the CPU along with Memory Controller etc.

Well that isnt true, because i just installed a bios update for my z87 sabertooth board with release notes saying it supports devils canyon.

jh30uk · 14 Jun 2014 at 18:13

If you reread what he said and I repeated then you will know he meant if the rumour was true that the Voltage Controller was supposed to be moved off the CPU onto the Mobo once again then DC would need a new Mobo so that is no doubt the source for all the non Z87 support rumours.

So seems Intel changed their minds.

The way it stands now Z87 can use DC and Z97 can use 4770k, if they did move the Voltage Controller that would not be the case.

I know it works on Z87, I have the Bios sitting here.

They be poor.

That guy is so not my cup of tea.

Thanks for that insight.

Intel specfinder website says VT-d is supported on both new K models.

PCPer review says so too:
http://www.pcper.com/reviews/Processors/Intel-Core-i7-4790K-Devils-Canyon-Review-and-Overclocking

Another interesting change is that both the Core i7-4790K and the Core i5-4690K enable support for both Intel's VT-d virtualization IO technology and Intel's TSX-NI transactional memory instructions. This makes them the first enthusiast-grade unlocked processors from Intel to support them!
