A PC magazine article reviewing a new AMD processor stated " .... with the extra instruction sets ...". I think they intended to say " ...extra instructions..." and to me this begs a question. To take advantage of these new instructions, I assume compilers used to compile operating systems and programs must be modified to support the new instructions. So in the short term there would be no gain using one of these processors with current versions of windows and linux. Also I think the review the magazine gave with regards to benchmarking may have been biased as the software they were using was most likley not taking advantage of the additional instructions. Perhaps it turns out that the processor developers simply work closely with the software developers and new versions or upgrades are good to go at the same time as the processor is released. Any one know how this actually goes down. Justin --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
