Tench Re.<<<I think it's safe to say that even AMD will need some "special compiler support" for future processors. How do you think those x86-64 extensions are going to be supported? How about Sledgehammer's new RISC-like floating-point core which will no doubt need specific support from applications? >>>>

Tench, I agree with both yours and Scumbia's position on this argument. Scumbia's because he probably is right that in every day use the ALU will have minimal impact. However using special compilers and benchmarks (We all know benchmarks can be manipulated to show whatever you want to show.)Intel will probably come up with special benchmarks which will enhance ALU as percentage of ops in that routine,and therefore come up with unusually high score; which Elmer will mention for the next ten years ad nauseum; even though he will know full well that that benchmark mainly shows off the performance of ALU, not general performance of chip.

Re: "And like I said before, how many support is there right now for those "Athlon New Instructions"? AMD said that with a 266 MHz bus and "projected compiler and prefetch optimizations," the Athlon can experience a 40%-50% improvement in SPECfp_base95. When will that happen?"

AMD is waiting for Intel to be "fair" and provide a compiler to take advantage of Athlon's features.
