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.

F*** i7. Im going this route! lol
I am tired of the double standard when it comes to Intel vs AMD. This is just a showoff for Intel... just as AMD did with the 7Ghz PII run.
65nm's needed 1.6V to 4ghz, 45nm's need 1.2V to 4GHz -> same -0.4volts of and 32nm's need 0.8V to 4GHz.
If that 0.832V is stock voltage it has 1000MHz OC headroom in it (the ES), mine does 700MHz OC with stock voltage.
But still very nice :p Now only problem is that low voltage Dual seems more interesting than current generation Quads. These will sell like crazy, if retails have same potential and quad core won't ever pick up in games. Unless it's indifferent to a game if it sees 4 threads or 4 cores performance wise.Most likely true, if not even lower limit. Bump up the voltage and they'll go heat crazy, so it's nice they run fast with low voltage.By the looks of it it's just XP stable :) So no.
THAT is what is really impressive - Faster IPC+4.5Ghz 4 threaded nehalem madness for cheap (i3) that is pretty nuts.
As for the argument of it performing clock for clock like i7...i very much dout it. it may be based on nahalem like i7, but pentium dual-core is based on core2 architecture but its performance is a good bit different from an e8X00 isn't it.
and yeah, that voltage is pretty low even for 4ghz
Most people are :O over what my xeon can do, let alone something this low.
even if this is a rare chip, 1.0v for FOUR threads (dual core + HT + IMC) means one hell of a good deal.
1,25v for 4Ghz bench stable for an unrefined ES still looks promising tho.
Phenom's II cant hold forever!
I don't hope for an AMD that can compete, just for an AMD that can survive this tough economical downtime. In a way live now so that you can fight another day, as they say.
edit: if someone has Wolfdale @ 4GHz on DDR3 board handy, would you mind running that EVEREST Cache & Memory Benchmark? Would be nice to compare.
I want to see real world benchmarks from Intels new offering before I get all excited and sell my rig. What looks good on paper or 3D06 may not translate into a worthy CPU replacement.
People laughed at AMD when they announced the Athlon all those years ago. Man did they change the face of computing. My point is anything can happen.
Its doing it with a decent amount less voltage, despite the fact its got more hardware within it.
