With the Intel/Linux solution, you win with raw CPU cycles and price but lose *big time* on cache size, memory bandwidth, and I/O. It's just the opposite with the O200 (win on cache, memory, I/O, lose on CPU cycles, price). If your problem is memory bound and you have a time-critical application it's probably worth the money to pay for the O200 box. If it's CPU bound then the Intel/Linux solution is more economically sensible. -Bob
