According to EE Times, IBM's Power6 processor will have two cores-just like the existing Power5-but it will double clock speed and memory bandwidth to 4-5GHz and 75GB/s, respectively. The Power6 will also have 8MB of L2 cache-over four times more than the Power5's 1.9MB cache. Despite these increases, the Power6's power consumption will remain in line with that of the Power5 thanks to IBM's 65nm SOI process, new variable gate length and threshold voltage techniques, and the fact that IBM hasn't altered the Power6's pipeline depth to achieve its higher clock speeds.

If there is anything IBM can do right, it's chips. Anything else though and you'll have to explain yourself.
