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.

Re: Where does this 64 bit IBM chip fit in?

Interesting that both IBM and AMD have come to the same conclusion that multiple cores are better than many parallel pipelines in a single core.

Good discussion of this approach at:
