80 Core Processor that uses less power than a light bulb

Intel Announces 80 Core Processor Prototype

WASHINGTON, Feb. 12 (Xinhua) -- Intel Corp. announced that it has designed a computer chip prototype which contains as much as 80 cores, performing more than a trillion calculations per second, U.S. media reported on Monday.

The world's biggest chipmaker said the unprecedented programmable computer processor, not larger than a fingernail, can conduct about a trillion calculations per second, a "teraflop." However, it accomplishes this unbelievable performance with just 62 watts of power when the chip is running at a frequency of 3.16 gigahertz.

Now that's a significant improvement. I'd heard a rumor of this 80 core beast about a year ago. I always wondered ... why 80 cores?
