That changes all the rules of the game and is doubtless a reaction to 800MHz Hypertransport (HT) chips from AMD that will arrive next year.
That has emerged from the latest roadmaps we saw on a rare visit to the Porcupine over the weekend.
The 667MHz front side bus for Northwood and Springdale is now dead, and will support DDR 400 memory, in a faster than expected move.
Intel also now feels it can produce additional processor speeds for hyperthreading technology introduced last week.
But Prescott has now been shoved back until Q4 of next year. Earlier Intel plans had Prescott in the second half of 2003. While, of course, Q4 is in the second half of 2003, it's not quite the same thing, is it?
Next year, the 400MHz system buses for Pentium 4s will completely disappear from the Intel roadmaps and sale pitches.
Q2 is an important time for Intel. It adds the "Canterwood" 800MHz FSB/DDR 400 chipset to its desktop roadmap which will then be its highest performing desktop chipset, supporting 800/533MHz FSBs, dual channel DDR400/333, and ECC memory, Serial ATA, and version 3.0 of AGP 8X.
Springdale is also changed. It will now introduce P, PE and G versions.
The P version supports 533/400MHz FSB and offers discrete AGP8X graphics, aimed at the entry level, while the PE offers the addition of 800MHz front side buses, and G also includes the higher bus speeds, as well as integrated graphics and discrete AGP 8X support.
Intel will also introduce hyperthreaded 2.40GHz, 2.60GHz P4s, and 2.80GHz Pentium 4s in Q2 of next year, as well as the 3.06GHz CPU it introduced last year and a 3GHz and a 3.20GHz hyperthreaded Pentium 4. µ
