The upcoming move to 533 MHz FSB may push Dothan into the lead vs the Opteron. Not bad for a 21 W TDP chip. Yes, of course the 533MT/s upgrade later this year will be at 27W. Re: The SPECfp score isn't special but keep in mind we are talking about a processor with only a 3.2 GB/s FSB. The 2 GHz Northwood Xeon MP with 400 MHz FSB and 2 MB L3 cache only gets 677 SPECfp_base2k - the Dothan core is about 61% faster on SPECfp at the same clock rate. FWIW, here's a good example of Pentium 4 performance during the transition from 400MT/s to 533MT/s FSB. Both submissions use the 6.0 Compiler. The memory is also upgraded to offer 1:1 bandwidth ratio. SPECint: Precision WorkStation 530 (2.4 GHz Xeon, 400MT/s) 2 x 256MB PC800-45 ECC RDRAM SPECint_base2000 = 825 http://www.spec.org/cpu2000/results/res2002q4/cpu2000-20020923-01680.html Precision WorkStation 350 (2.4 GHz P4, 533MT/s) 2 x 256MB PC1066-32 ECC RDRAM SPECint_base2000 = 905 http://www.spec.org/cpu2000/results/res2002q4/cpu2000-20021108-01794.html SPECfp: Precision WorkStation 530 (2.4 GHz Xeon, 400MT/s) 2 x 256MB PC800-45 ECC RDRAM SPECfp_base2000 = 821 http://www.spec.org/cpu2000/results/res2002q4/cpu2000-20020923-01679.html Precision WorkStation 350 (2.4 GHz P4, 533MT/s) 2 x 256MB PC1066-32 ECC RDRAM SPECfp_base2000 = 965 http://www.spec.org/cpu2000/results/res2002q4/cpu2000-20021108-01795.html That's a 9.7% improvement in SPECint and a 17.5% improvement in SPECfp. If Dothan gets this much of a benefit, it would have a SPECint of 1676 and a SPECfp of 1277. To put that in perspective, the Dell Precision Workstation 360 (3.4 GHz Pentium 4 Extreme Edition) gets a 1658 in SPECint and the Dell Precision Workstation 360 (3.2 GHz P4, DDR400) gets a 1267 in SPECfp. Dothan would be faster than both of these. Intel has a major winner here with Dothan. All they need to do is productize it in more segments.
