Since I work for vBulletin.com I'm always interested in seeing how cpus fair for web/database serving tasks - especially how they handle high scaling concurrency

AMD Opterons are blowing away P4 Xeons by a mile in performance and in performance to cost ratios!

50,000 user apache concurrency test

Intel Dual P4 3.0GHZ Xeon = 1043.7
Intel Dual P4 3.2GHZ Xeon = 1106.1
Intel Dual P4 3.4GHZ Xeon = 1155.6
Intel Dual P4 3.6GHZ Xeon = 1215.3
AMD Dual Opteron 248 = 1345.9
AMD Dual Opteron 250 = 1389.4
AMD Dual Opteron 252 = 1426.0
AMD Dual Opteron 265 dual core = 1587.3
AMD Dual Opteron 270 dual core = 1778.7
AMD Dual Opteron 275 dual core = 1874.6

Intel dual core 2.4ghz Xeon = 1099.8
Intel dual core 2.6ghz Xeon = 1171.3
Intel dual core 2.8ghz Xeon = 1199.4
AMD Dual Opteron 265 dual core = 1510.1
AMD Dual Opteron 270 dual core = 1686.6
AMD Dual Opteron 275 dual core = 1722.2
AMD Dual Opteron 280 dual core = 1968.2

Woah the difference

Looking to compile some MySQL concurrency numbers but it's hard to find comparable reviews but Opterons show as much if not more improvement in mysql as in above apache concurrency tests
