Yup, they're clocked about where I'd figured they would be. The C2D LV chips were 1.333 and 1.500 GHz and had a TDP of 17W per die and the fastest regular Core 2 Duo T7600 has a TDP of ~35W, so I'd have figured something in-between, in the upper 1 GHz range.
What will be interesting to see is how AMD will combat that push against their server space. A pair of 22x0HEs will consume 67W per socket and return overall a similar power draw to the LV Clovertowns once you add in the motherboard. But there's nothing that can come close for eight cores- an 82x0HE setup will use over twice the power as the QC Xeon LVs. Barcelona should be interesting as the HE versions of are suppsed run at about 70W up to 2.1-2.2 GHz, where they should outperform the Xeon LVs in both raw performance and performance-per-watt, assuming that the Barcelona is at least as fast clock-for-clock as the Core chips are. (I'm not going to get into THAT discussion here, but I think that it's a safe bet to say that they should at least get IPC parity.) However, the Barcelonas will draw greater power overall. Maybe they will just stick to the performance-per-watt metric and forget about trying to match Intel watt-for-watt, otherwise there might be some lower-clocked Barcelonas that aren't on the roadmap getting released. It will be interesting to say the least.
