I'm sure Anand will have his review up shortly, they're sprouting like mushrooms all over the net right after 12pm here. Anyways, check out Ace's Hardware review of the chip. In the article, they focus mainly on overclocking, since the typical report of "it's the same thing but 7% faster" gets tiresome fast.
Apparently the 1.3ghz Tbirds are using a new stepping, identified by the AXIA markers on the chip. They and other places are reporting overclockings of up to 1.5ghz air cooled. That may not be a big deal for the P4, but it sure is for the Tbird.
Also, apparently this stepping, like many of the 1.2g processors out, are factory unlocked.
That does't mean that much to me right now, but I'm sure that in time, the new stepping will trickle down to the slower speed grades, in which case, the overclockers should have a nice little field day.
the other interesting point of the article is that the benefits of DDR start showing up much more as processor speed increases. For example, in MPEG encoding, there was, initially, an 8% gap between SDR and DDR. At 1.45ghz, the gap has widened to almost 16%! It's pretty clear now why the P4 has a dual-channel RDRAM memory system, and also why mating it with SDR is going to provide some seriously castrated performance.
