Well, firstly, the name 'Pentium 5' has not been decided on yet. It will most likely still be marketed under the Pentium 4 name.
It is really just a core change. First we had Wilamette, then Northwood, and now Prescott. Presott still uses most of the Pentium 4's Netburst architecture, so it is still really a Pentium 4 chip.
And all of the information you just listed, emu_kidid, was revealed well over a year ago. Don't tell me you are just learning of Prescott? It is the first core to use a 90nm process (considered nanotechnology by Intel) and also the first chip to use strained silicon, which should prove quite useful to the scaling of the chip into the future.
Also, your information is not entirely correct, Ace. Prescott is capable of 64-bit instruction sets but I believe only at a 8-bit level of floating-point precision, which pales in comparison to AMD's Hammer. And LaGrande is just rumored to be coded into the core... it might be left out in the end if not completed. And, finally, the FSB clock will likely be 200mHz and not 166mHz, but that isn't final. Intel could change many things before it's launch.
By the way, this core is likely to scale up to at least 4.7gHz before Intel unveils its entirely new microprocessor in 2005. So Prescott is really paving the way for technologies Intel plans to implement in the future. This core will likely be the Pentium 4's last and it's lifespan looks to be no more than 16 months.
