<One more "consultant" from Oregon on our heads Other than name-calling, this sentence would mean what?> Well you've got to admit that Oregon produces people like Bob Packwood, Tonya Harding, and Monica Lewinsky. ;-) (At least Oregon has Picabo Street and the Portland Trailblazers.) <I'm trying to have a friendly conversation here, and maybe even learn something. What's your problem?> Don't take it personally. If he's not insulting you, you can take that as a compliment. Tenchusatsu

Eric, <..and maybe even learn something.> If you want to learn, ask a question, politely, instead of making short-sighted statements. Now try to comprehend one more time: <A synthetic benchmark shows the potential of a processor for running applications that are similar to the benchmark.> Narrow thinking, student. Try to comprehend one more time: A real-world application consists of variety of code patterns that are executed mostly sequentially. A real-world benchmark measures the time to execute the sum of all these patterns. A synthetic benchmark usually synthesizes one of those code structures, or kernels, or "basic blocks": - control flows, block copy, matrix multiply, system calls, process forks, etc. If one processor executes most of the basic kernels better than another, it has better chance to better execute an average real-world code. That is why your statement "Scoring high on a synthetic benchmark DOES NOT correlate to faster performance running real applications" is highly inaccurate although formally correct since you said "a synthetic benchmark", not "benchmarks". FYI, the Norton SI benchmark contains not only a single synthetic pattern but a variety of them, and it DOES CORRELATE with certain class of real applications. Scoring good on synthetic benchmarks but poorly on real applications usually indicates a flaw in system design, not necessary in CPU itself. Example: those lame Triton chipsets from Intel, with look-aside memory-blocked L2 cache. Have a friendly conversation.
