"Prescott, the next generation Intel processor will hit the streets in the 4th quarter of 2003. The Prescott processor is the code name for a new generation of IA-32 processors. It is expected to debut at 3.2GHz and will eventually scale up into the 5GHz region. The timing of its release will coincide with AMD's Hammer processor brings Prescott into direct competition with it.
Although based on the NetBurst architecture similar to its Pentium 4 predecessors, Prescott nevertheless features a slew of enhancements to its micro-architecture with improved Hyper-Threading Technology, advanced power management, 13 new instructions and larger caches.
Intel is fabricating the Prescott on huge 300mm wafers with its cutting edge 90-nanometer (90nm) strained silicon process. The 90nm process enables Intel to pack in more cache into Prescott. Prescott doubles current Pentium 4 cache figures with 16K of L1 and a whopping 1MB of L2 (as a comparison, the current L2 record holder for is AMD's Barton core with only 512K of L2). In order to fit such a large amount of cache into the core, Intel added a 7th copper layer paving the way for >100M transistor counts. The 90nm process also includes certain features which allows for higher clock frequencies and lower voltages in the neighborhood of 1.2V. The larger cache will aid the processor in pre-fetching and storing data close to it for faster processing."
