Petz, <A Katmai core? No other Katmai's were made on 0.18, or with SSE. The MTH hub to translate SDRAM to RAMBUS formatting will also slow the thing down. I'm getting less worried about this chip being any competition for Duron systems.>
Katmai was the original Pentium III, a.k.a. P6 with SSE. In other words, all Katmai cores have SSE.
Yes, it's pretty strange to call Timna's core a "Katmai core," given that Katmai is 0.25u and Timna is 0.18u. I guess "Coppermine core" would make more sense, but that could imply that Timna borrowed the Coppermine design. That might not be the case, given that Coppermine and Timna development took place at the same time at different ends of the world. So it could be that both Coppermine and Timna are based off of the Katmai core, but both design teams went their own separate directions, even though the results may be similar.
As for MTH, yeah, it's a shame that Timna isn't going to debut on RDRAM. However, Intel seems pretty confident that in 2001, Timna will make the transition to RDRAM. In any case, Timna is aimed at a market which Intel is assuming cares more about cost and less about performance. If Intel's assumptions are right, Duron will have a hard time competing against Timna in that market. (Duron will probably be successful among customers who care more about performance than Timna's customers.)
