32nm Clarkdale sample overclocked to 4GHz

If the latest Internet rumors are correct, Intel plans to ship its 32nm Clarkdale processors next quarter, ahead of schedule. That would certainly explain why famed Taiwanese overclocker Coolaler has already gotten hold of and overclocked a Clarkdale sample—or so he claims.

Apparently, Intel designed the sample in question to run at 3.07GHz with its two cores, four threads, 256KB of L2 cache per core, and 4MB of shared L3 cache. Coolaler's CPU-Z screenshots suggest the sample reached a cool 4GHz with just 0.832V of juice. Presumably, the processor's Turbo-Boost functionality could push individual cores even higher in certain applications, too.

If you're into hardware eye candy, Coolaler's post also includes several high-resolution photos of the Clarkdale processor. The CPU is supposed to have the same LGA1156 package as upcoming 45nm Lynnfields, but the layout of the bottom capacitors looks consistent with the dual-chip design Intel showed a while back—one of the chips houses the two CPU cores, while the other is home to the memory controller and GPU.
