McSquealy's SPECS very similar to the AMD "wet_dream_MHz" ----------------------------- ABSTRACT: On Monday, November 19, Sun announced that its upcoming 1050MHz UltraSPARC III processor (due in Q1-2002) gave an impressive 32% and 72% performance increase on the SPECint and SPECfp benchmarks respectively. These gains seem incredible, considering the clock rate was only increased 17%. Sun attributes the increases to "...improved manufacturing techniques, enhanced internal buffer sizes and management, and more efficient object code generated by a new version of the Forte compiler." No one in the benchmarking field believes that Sun performed the benchmark correctly. There are many ways to cheat on the SPEC benchmarks and it's just a matter of time before the industry figures out how Sun actually cheated. Please see the quote below from John D. McCalpin, Ph.D of IBM. "It is well known that this benchmark has high-bandwidth accesses to a small working set, and that systems with 8 MB L2 caches should have essentially no cache misses. What is not clearly understood is how Sun managed to deliver ~4x the performance of other cpus with 8 MB L2 caches -- There is a pointer disambiguation issue in one of the main loops, but it is not clear that even if the compiler could prove a lack of aliasing that the results would be improved this much. I am sure that more information will come out over the next few weeks...." The bottom line is it's just a matter of time before Sun is ridiculed by the industry for this result.
