Dual Woodcrest 3GHz VS Dual Opteron 285 2.6GHz

Ah, much better than Netburst. The Woodcrest system draws a little more power than the Opteron box with PowerNow! does at idle, but once both systems are busy rendering with all four cores, the Woodcrest pulls less juice.
Perhaps more importantly, there's only a 12 W difference between a single and dual Woodcrest config at idle. That CPU just isn't drawing much power at all. Under load, the difference is 59 W—much less than the 80 W TDP of the 3GHz Woodcrest, and under the 65 W target for the lower-speed Woodcrest processors.作者: ultraghost 时间: 2006-5-24 15:31

It's taken some time, but Intel finally has a strong answer to the Opteron—or nearly so. The Bensley platform provides a much-improved infrastructure for low-end and mid-range servers, with vastly more bandwidth to each CPU socket—and to main memory—than previous Xeon chipsets. When they arrive, Woodcrest-based Xeons look like they will allow Intel to recapture the performance lead in server and workstations-class CPUs. We obviously haven't tested server-class applications yet, but the performance lead we've seen from Woodcrest in nearly every test we have run bodes very well indeed. So do Woodcrest's power consumption numbers, which are a revelation compared to what we've seen from Netburst processors in recent years.
Of course, when Woodcrest-derived Xeons do arrive, they may be contending with the upcoming revision-F Opterons with DDR2 memory, lower system power consumption, and perhaps higher clock speeds, as well. Will these changes be enough to keep AMD competitive against Woodcrest? That's hard to say for sure, but it certainly doesn't look like life will be easy for AMD.作者: 明镜止水 时间: 2006-5-24 15:39
The CPU coolers and the FB-DIMMs, all of which are helped by active cooling in this server box
