Intel Woodcrest, AMD's Opteron and Sun's UltraSparc T1: Server CPU Shoot-out anandtech.com The Intel Xeon 5160, a.k.a. Woodcrest, will simply be the most powerful server CPU this year (though it's not yet available for purchase of course). As our extrapolated calculations show, even a 2.6 GHz Woodcrest will outperform the current Opteron 285 with a 5 to 55% margin, nothing short of impressive. The new Xeon is however not invincible: the Opteron can still give some serious resistance when running some instruction mixes with lots of rotates, add-carry or load effective address instructions. RSA, AES and other benchmarks clearly show this. Intel will still have to convince some software vendors to port to SSE if it wants Woodcrest to be the completely superior CPU. The advantage in MySQL is also rather small, a result of the relatively high latency of the FB-DIMMs. But we are nitpicking: Intel's newest Xeon has taken back the performance/Watt crown. In one word: Woodcrest rocks!
