Penryn Officially Unveiled

As expected, Intel officially unveiled today its Penryn CPUs, with 5 models dedicated to its mobile platform:
T8100: 2.1 GHz 3MB cache FSB 800 MHz
T8300: 2.4 GHz 3MB cache FSB 800 MHz
T8930: 2.5 GHz 6MB cache FSB 800 MHz
T9500: 2.6 GHz 6MB cache FSB800 MHz
X9000: 2.8 GHz 6MB cache FSB800 MHz
The last model should find its way in the iMac, as its TDP makes it unfriendly for being use in notebook (or it would strongly reduce battery lifetime).
If the clock frequency did not significantly increase when compared to the first Santa Rosa-dedicated CPUs, the Penryn and their SSE4 instruction set bring a substantial gain of performance for multimedia applications, and will be noticeably enjoyed by Mac users with 10.5.2.
The improved power management technology included in Penryn mobile CPU should further increase battery lifetime (such as turning L1 and L2 cache off when the CPU is idle).
So, with such new mobile CPU offer, one will simply need to imagine the future MacBook Pro, MacBook, iMac and let's hope Mac mini.
Intel also unveiled new 3xxx Xeon CPUS. They are different than those to be found in the future Penryn powered Mac Pro, as they can not be used on dual socket motherboard, and are in summary renamed Core 2 Quad. However, Apple might use them for offering a entry-level tower model, much cheaper than the current entry-level Mac Pro.
