I don't agree. Because of the extra registers and other tweaks I get considerably more performance on processor intensive computational tasks. YMMV depending on your task mix.

Just how much of the standard load of software other than games are computational intensive? Any gains in computation speed are wiped out by the mundane tasks . Every program needs to use pointers for just about every single memory reference. These all double in size and moving one byte from one memory to another now requires in excess of twice the overhead. Twice the pointer size, twice the minimum memory access size. If you move big chunks its faster to to move 8 bytes at a time than 4, but the minimum memory access is now 8 bytes rather than 4. -- _____________________________________ John Andersen
