First Intel Clarkdale Core i3 Low-Voltage Overclocking Feat Yields 4 GHz at 0.832 V

Intel's upcoming dual-core derivatives of the Nehalem/Westmere architecture, codenamed "Clarkdale" seems to have some interesting electrical characteristics. The CPU component of the chip is built on Intel's brand new 32 nanometre process that facilitates higher transistor densities, and in the process, intends to bring down TDP. An overclocking feat by Coolaler.com seems to suggest one of two things: either these chips have naturally low vCore voltages, or that the overlocking headroom at low-voltages is exceptional. Coolaler used a pre-release engineering sample of the Core i3 Clarkdale processor on a compatible platform, and achieved 4 GHz of clock speed with the vCore at 0.832 V. The frequency multiplier of the CPU was set at 25.0x, and a bus speed of 160 MHz used. Intel will be ready with these processors by the end of this year.

low voltage == low temps :)

5 Ghz at 1.3v ? I think sooo... w/ 4 threads, dual is not dead yet :D.

those are very serious reports. With that kind of headroom, and 5GHZ air is a possibility, these will be better for gaming, and I plan on getting one.

Pretty nice. As always though 4ghz is meaningless w/o knowing how much it can do per clock cycle, which we really don't have any indication of yet other than it's nehalem. These are different beasts than i7 though.

its the same architecture though... for sure the IPC is higher than c2d, and even a 4ghz c2d is a great performer - at 5ghz its a monster. Anyways low voltage doesnt always mean a good high voltage clock no?

We already know what it can do per clock cycle. While it is not the exact architecture of nehalem, it will follow it's performance clock by clock, atleast.

It has half the L3 cache of i7 and uses a different method of communication with the memory and rest of the system. It's a different socket. What makes you think b/c they call it nehalem it's the same?

That's an ES so who knows if the retail version will have such a high multi.

What kind of cooling was used, I don't think that was mentioned anywhere(and I can't read whatever language the source site is in). I mean, if he was using LN2, then that low of a voltage doesn't seem that great. If it was air, then this is great.

The "terrible" is "terrific" btw :)

He said he'll give out more details once he's back from vacation.

Ah, thanks. Then it is on air, that is amazing.

Anyone know the price? These would be AWESOME for crunching!
