Jim, <Where does this 64 bit IBM chip fit in?>

IBM will use the chip as a building block for future RS6000 servers. One chip will have two CPU cores on it, providing a very compelling 2-way server on a chip. And unlike conventional 2-way servers, the two cores on the chip will be very tightly coupled.

Then IBM will put four of those chips onto one 4.5" x 4.5" module. The four chips on the module will communicate with each other via a network of very high speed point-to-point ports. Essentially you'll have an eight-way server on a module. Of course, the module will be extremely expensive thanks to its 5,200 I/O pads, but cheaper than a conventional eight-way server.

Beyond that, IBM could take a bunch of these modules and go beyond 8-way servers. Eight of these modules put together can make a great 64-way server.

In short, IBM's solution looks very innovative. While Intel is looking for more instruction-level parallelism with IA-64, IBM is going to exploit thread-level parallelism with the Power4.
