"Sun Surpasses IBM for Server Leadership: New High-End Sun Fire Systems Give Sun New Edge; World-Record Benchmarks Released"
Well, before you get excited, you might want to read their Benchmark Footnotes at the bottom of the page. If you do, you'll see the Sparc IV+ core (CPU) performance is about half that of the Power5 core for almost every benchmark they list.
The difference is that Sun reported performance on the number of chips for Sun servers, and the number of cores for IBM servers. Since there are 2 cores (CPU's) per SparcIV+ chip, this overestimates Sun's performance by a factor of two.
Is this leadership?
