Anandtech reviews Sun's T2000 Coolthreads server, and concludes: "At first sight, Sun has won the performance/watt battle for now, but it cannot rest on its laurels. Low voltage versions of the Xeon 'Woodcrest' and Opteron might be able to come very close to the performance/Watt levels that the T1 offers. We also can't shake the feeling that the number of applications, which will really exhibit the kind of exceptional performance that Sun's own heavily optimised benchmarks show, will be quite limited. Last, but certainly not least, Sun's solid engineering has impressed us. Sun's meticulous attention to detail resulted in a sturdy, well-polished machine." More benchmarks here.
