Intel Prescott with Hammer expansion and 1MB L2 cache?
If it were up to Hans de Vries from the online magazine 'Chip Architect', the Pentium4 Prescott will have both the hammer extension and a 1MByte L2 cache. Compared to the Willamette, the Northwood has already shown that the Pentium4 would benefit from an even larger L2 cache due to its architecture.
However, increasing the L1 cache would be at least as useful as the Pentium4 is currently lagging behind the competition. Intel does not have to worry too much about high clock frequencies, since the Prescott is manufactured in 0.09µm technology and can therefore be operated at well over 3GHz. According to 'Chip Architect', Intel is also using the Yamhill expansion, about which little is known so far, for the Prescott in order not to fall behind the toughest competitors. The Prescott could also process x86-64 software without any problems. But whether AMD's or Intel's x86-64 engine will be faster in the end cannot be judged at the moment. Unfortunately, Intel has not yet made any official statements on these points. A little more clarity can only be expected in June at the VLSI 2002, since Intel would like to publish specifications about the architecture and presentations on the Prescott there.
