Intel Devil Canyon officially unveiled

[Yureak]

The black residue is a silicone based gasket sealant not epoxy. To remove epoxy you need heat or some sort of solvent. I DIYed my 4770k delid so that's what i feel it is.

The TIM for Haswell is actually similar to those used in power amplifiers for radar transmitters. It drys pretty fast leaving the particles to fill in the space between the 2 surface.

So IF the TIM for Devil Canyon is really some sort of 2-part epoxy TIM and the temps are still crap, there will be a lot of disgruntled ang mo in the OC forums.

wow engineer knows what he's talking about

Just saw this while flipping thorough the pics.

Intel promise you "Up to 4.4GHz" with foot note, "Refers to the maximum single-core frequency that can be achieved with Intel(r) Turbo Boost Technology."

means what?

turbo boost to 4.4GHz on one core only, anything more is a bonus?

All along turbo boost kick in when u are using less cores than the original one. It give the max boost when u are using single core.

For 4790K, it wasnt mentioned but the turbo boost actually kick in when using 4 cores. However it will not go above 4.2GHz


So its more of a 4.2/4.4 boost rather than a static 4.4GHz boost

err.. for my 4770K max turbo boost on 4 core is 3.9Ghz which is what is stated on the box and actual performance. Single core can go up to 4.7-4.8Ghz but I don't see intel marketing it as "Turbo Boost up to 4.7Ghz"

Anyway I think my 4770K is going to die liao. it's taking 1.137Vid running @ stock speed.

Buying a G2358 when you pretty much have to buy a Z87/97 mobo. Foolish.

To those who don't know i'm not mentioning which mobo chips is unlocked as well

thx for correcting, silicone not epoxy. but main point is, i'm thinking the polymer thingie may be referring to the black adhesive (guessing only).

edit: scratch that, it seems TIM does indeed have some polymer matrix thingie...

Anyway the heat issue prevail for a long time. Intel did mention their reason for not using fluxless solder. IIRC the small die size with solder cause the chip to crack easily.

Kinda BS... Back in 2006 Intel used fluxless solder on the similar sized Conroe die for Core 2 Duo E6xxx.

finally 4ghz stock speed
very nice

time to bid farewell to overclocking

Ironically u have to buy a K cpu to get 4ghz stock speed.

Yes. Thats what turbo core means. If using just 1 core, it can run up to 4.4GHz. If 2 or more cores, speed will drop. If all 4 cores, 4GHz only.

So now 4790K clock to 6.4GHz under LN2?


That is pretty fast isnt it?

 

[manshen]

nothing ironic
frankly speaking it doesnt matter, and i dont care if its k or non-K
the ability of 4ghz stock speed, just this alone, is good enuf for celebration

just like when integrated graphics was introduced, its was very good, since it meant that we can do away with discrete graphics card i.e. one less burden/hassle

now this is another step forward, so we can do away with the burden/hassle of overclocking

HELLYEAH!~

Huh......... SB/IB/Haswell all can run 4GHz at stock voltage using stock heatsink.......

No hassle needed even..... Just set multiplier to 40x in BIOS.

This is not a step forward at all. The only real challenge is hitting 5GHz which is very hard to achieve.

Yeah, but not for daily use so no point. CPU won't last long under those condition......see the voltage....

I dont think that is the case. Try it on a non K version and see. It will never go beyond the turbo boost stated speed.

You cant set multiplier with non K version. That is also why it is ironical that u need a K version for a default 4GHz clock.

Nonetheless it is still good since it was 4-4.4 right out from the box.

I've noticed that there is a huge difference between older hardware enthusiasts and "current gen" ones.

Back then, people OC to get real leaps of improvements so they can play their games smoothly. Now even a Pentium can play a lot of games smoothly with a decent GPU.

Most if not all "overclockers" now are just targeting the 5GHz mark to boost their e-peen. They wont even know if there will be a noticeable performance improvement between 4.2/4.4GHz and 5GHz, a paltry 0.6GHz. Its not even "hard to hit the 5GHz mark" now, its just the hardware equivalent of "chasing numbers" in real life.

Its sad how far downhill the community has gone in just a few years.

Devil's Canyon still cannot annihilate the prowess and might of Bulldozer at 8 GHz mark...

Meh, highest during yesterday's OC competition was 5.498GHz leh

That 6.4 GHz was at MSI's own Computex exhibition.

Was implying that below 5.5GHz is what you can expect with normal consumer non-cherry picked chips and non-extreme cooling. Intel makes OCing feel more dead these days

I wonder what voltage and cooling they are using......

Lol..... I guess we are hitting limits of current silicon technology. Despite small process, it does not aid overclocking at all....I was so disappointed with the Tri-gate and 22nm process when IB came out. It does not improve oc but actually degrades it....lol...

For me, I have been wanting to having a 5GHz CPU since SB days.... NEver did occur. Now using a AMD running at 5GHz. If Intel can hit 5GHz I may decide to change.
