AMD "AMD described its forthcoming quad-core processor, codenamed Barcelona, in a session at today's Microprocessor Forum. Details of the new microarchitecture on which the processor is based (codenamed K8L) have been known for some time now. Still, the event brought some new info, and here are some highlights that I've culled from some of the reporting on it."

Just play chess ;-P

Seriously, go is not that sort of game computers are really good at because the board is too large, creating too many possibilities.

Very rough estimate:
chess-board: 8x8=64
go-board: 19x19=361
Now the number of possibilities increases approximately exponential with time "t", meaning:
possibilities(chess)~64^t
possibilities(go)~361^t
Now chess opening theory is about 10 turns (there's more but real chess computers stop relying on theory from this point on).
10 turns means:
possibilities(chess)~64^10=10^18
possibilities(go)~361^10=4*10^25
7 orders of magnitude between them.
Moore's law predicts sufficient computing powers no sooner than 2040. If it remains true.

There are problems where brute force is a suitable strategy but go is probably not one of them.

But you might hope for quantum computing, evaluating all possible choices at the same time.
Now you only need a way to make the machine let you win from time to time :-D

On a side note, I find it really strange to put more and more cores into one machine and at the same time virtualize the machine so that it can be used by several OSs and people at the same time.
I know it makes sense but it feels _really_ strange...

I think I'll wait until quads are somehow mainstream and get a really cheap dual core then for ripping or compiling stuff in the background.
