IBM finally took the wraps off its much anticipated Power6 microprocessor, which company executives said will double the clock speed of its current Power5 chip, without stretching the power envelope. The Power6 processor, unveiled at an event on May 21 in London, is a dual-core chip with a top clock speed of 4.7GHz, double the 2.3GHz of the Power5+ processors. The new chip also includes 8MB of L2 cache - four times as large as the current Power5 offering - and an internal bandwidth of 300GB per second. Ars' John 'Hannibal' Stokes obviously also has his say.

Barcelona is 281 mm^2, but it's also a server processor. You're not going to see something that big in an iMac-class machine anytime soon.
I'm gonna break my own suggestion and mention Apple here. Notice how they're shipping 8-core (!) 3.0 GHz PowerMacs starting at $4000. They've gone from topping out at 2 cores with the 970MP to topping out at 8 cores with the Xeon, in the space of less than a year. Can you possibly imagine POWER competing with that kind of price/performance? How much is an 8-core POWER6 machine gonna cost, even stripped down to to target Apple's decidedly low-end market?

IIRC, AMD's new Barcelona/Phenom is over 300 sq. mm.
