Intel "Devils Canyon" Launch - Reviews, OC Info, Availability

[Homeles]

Yes. That's my point.

It goes both ways; i.e., their loop might be below average.

 

[TreVader]

That is disappointing. I would hope for 5ghz underwater.


It looks like Haswell-E should offer much better OC opportunities. It also looks like the stock turbo is very high and I expect Haswell-E to hit 4.5 on air pretty easily.

 

[Ajay]

That's 4.8GHz under water. Unless this is an exceptionally bad chip, this isn't a notable improvement.

It's Digital Storm. I'm sure they had more than one chip available to them. This is probably what they plan to ship in overclocked LC systems. So it's not likely to be an exceptionally bad chip or an exceptionally good one. I would imagine that they bin their own chips putting the less overclockable ones into stock systems and saving the better ones for overclocked LC systems - but they wouldn't want to push them to the limit and risk having some fail prematurely.

TL;DR - unless Digital Storm is being very conservative, this is what most people can expect from OCed LC systems.

 

[StinkyPinky]

To be honest, it does look a bit like that the 4790k is just a factory overclocked CPU for people that don't have the confidence to do it themselves. That's understandable though.

That doesn't explain the temperature or power consumption.

I wasn't commenting on those - just the 4.8 GHz overclock. Other than the PC having a 360 mm rad, we don't know much about the system. As usual, we won't have a better picture till allot more reviews roll in. Doesn't mean we have to stop speculating till our eyes bleed

From their written article - http://www.digitalstormonline.com/unlocked/intel-4790k-overclocking-review-and-benchmarks-idnum295/

Although people were hitting 5 GHz+ at the Intel event, the chips that were used there were definitely binned and they also had liquid nitrogen running in their setups. It’s also important to keep in mind that we only had a single CPU on hand to test so we couldn’t bin the 4790K to find the best overclocker out of the bunch.

 

[AtenRa]

Nice for Air cooling, the sweet spot seams to be in the 4.4GHz area for lower power and temperatures than 4770K. But from the video they seam to used a 120cm fan on the VRMs heatsink and that may not be the case in a closed PC case for everyone.

[Freddy1765]

Meh, based on those results it seems I'm sticking with my trusty 2500k until BW-k chips are released in a year or whenever.
I've no intention of splurging on what is effectively a 4770k with marginally better thermals..

 

[Grooveriding]

I don't think anyone reasonably expected to get the same percentile of overclock headroom over stock clocks out of a 4790K as you can a 4770K.

My guess is most do 4.6-4.8ghz and cherry chips manage 5ghz. You'll probably need robust cooling for 4.8-5ghz as well due to the amount of voltage it's going to take, probably custom water for anything reasonable temperature wise.

 

[Bman123]

This is looking like a huge let down for me. I skipped ivy waiting on haswell. That came and wasn't what I expected so I waited on a refresh. Now we have the refresh and I'm not sure I even want to spend the money on this.
What is the next scheduled Intel CPU change, broad well or skylake in 2015?

 

[Techhog]

So, nobody's gonna call Intel out for false advertising and the fact that these aren't an improvement at all? Okay. From my perspective, there's no reason to pay extra for these.

 

[Freddy1765]

You don't pay extra, the 4790k/4690k simply replace their counterparts at the same price point, with improved thermals. That being said, these new chips are no more than what the old Haswells should've been in the first place. So yes, bit of a letdown.

 

[Bman123]

Looks like I'm waiting on the next MC sale when the i7's go for $199. I've waited this long what another 6 months

 

[BFG10K]

+500MHz while using less power and running 7C-8C cooler isn't an improvement?

 

[Techhog]

I mean no improvement for overclockers.

 

[frozentundra123456]

Exactly. It is still too soon to say really until we see more tests. Maybe it was over hyped, and I was hoping for 4.8 to 5.0 on a good air cooler. Otoh, since they didn't raise the price, you are getting 10 % plus improvement at stock and some improvement when overclocked for free. Seems like a good deal to me. At least Intel is trying to show some interest on the desktop. Only thing else I think they could have done is go back to solder. Who really knows if that would have helped.

 

[blackened23]

This has to be a joke and you're just bashing "just because" which isn't dissimilar to what loose AMD wingnuts generally do. But the fact of the matter is many 4770k chips can't even get 4.4ghz reliably. But we'll just ignore that. The chip is clearly binned for higher clockspeeds, and it runs cooler at lower voltages with the stock cooling. 4.4ghz at 1.1xV? My 4770k can't get 4.4ghz without 1.25V. Obviously the chip is better binned.

Yes, the intel stock cooler sucks. Thanks for pointing this out, captain obvious. Under stress tests it is not abnormal for the intel stock cooler to hit 80C. You're acting like this is a surprise or something. Give me a freaking break. Even with a liquid AIO, if you over volt a Haswell, 80-90C is not abnormal during stress testing. But the chip can withstand those temps with NP. Yes, if you pump 1.25V+ into a Haswell chip, the temps are going to be high when AVX instructions are used. But stress tests don't mimic real world with Haswell, and your real world temps likely won't be anywhere past 65C. At least this is my experience. I can get 85C in stress tests, but always 60C or less in the real world. Because real world doesn't use AVX instructions and endless FPU stressing.

I can say assuredly that since most 4770k chips require 1.2xV for 4.4ghz with many not even GETTING 4.4ghz, that the stock cooler would fail utterly at 4.4ghz. But this chip is getting 4.4 with acceptable temps at 1.1x V with the crappy intel stock cooler. The 4770k cannot do this with the intel stock cooler. Clearly it is better binned.

Besides which, if you have a 4th gen core i5 or i7 already, you're really not the target market. Dear captain obvious, if you have a 4th gen core CPU already you have no reason to get this CPU. Yearly upgraders are not the norm and are not the target market. Not even I have done yearly CPU upgrades most of the time, and I know I upgrade my CPU more than most folks. Stop looking at this from the perspective of someone trying to upgrade from a 4670k or a 4770k. That is absurd. While the 4790k IS BETTER AND BETTER BINNED than the 4770k, that doesn't mean that a 4770k is the target market. Come on man. What kind of upgrade would 300mhz give you on the same uarch? That would just be stupid to buy as an upgrade; I understand some will buy it as a "just because I wanna to have the latest and greatest" which is cool but from the perspective of someone who wants a clear and noticeable speed increase from 4770k? Stupid. Most people do NOT yearly upgrade their CPU. But, this is going to be a great chip for those upgrading from nehalem or lynnfield systems, and even SB level systems.

Personal attacks will not be tolerated, and for that you can take some time off

How does the turbo work on the i7? Is it 4.4ghz on all cores or just one? I don't remember seeing that

 

[blackened23]

It depends on your motherboard. You can configure what happens when turbo kicks in. This is fully configurable on asus motherboards, you can set per code turbo speeds at load.

That's what I do, and I understand that ME also does this. Most people enable multicore enhancement which puts all cores at full turbo speed under CPU utilization. I don't know of anyone who DOESN'T do this. I know both my 3770k and the 4770k which replaced it put all cores at the turbo speed at full utilization.

I'm not exactly sure how stock turbo works because frankly, I haven't NOT used multicore enhancement for a long time - even with the 3770k, I used ME which put all of my cores at 4.7ghz under turbo. I'd say this is what most overclockers do.

Interesting. I didn't imagine that they would only have one CPU on hand. I guess it's not like they are HP. Thanks for the correction!

 

[24601]

Dunno why anyone expected 5ghz average OC when they aren't even using solder.

Get Haswell-E. Don't get reamed too badly by DDR4.
....
....
Profit?

Hopefully Intel didn't fail on the power on the package so that Haswell-E isn't limited by power delivery problems.

4.2 Ghz on all cores, 4.4 Ghz on 1-2 cores.

The i7-4790K represents Intel’s first ever consumer processor with a base frequency of 4 GHz (we have CPUs that turbo this high), but the turbo mode for this processor is actually 4-4-3-2, meaning that at single core loads the user will see 4.4 GHz and at full-core loads it will be 4.2 GHz.

[MisterMac]

....just as i said earlier.

A desktop power user cannot be excited by less power delivery for 100? 200 mhz? average more OC.
F-That to be honest.


This is intel reaming the OC\Enthusiast crowd and Mobile\ATOM taking centerstage.

We are not important anymore - so i geuss we better start buying server\-E chips and hope they lower their prices in those segments longterm
