NetBurst architecture introduced by Intel in Pentium 4 processors seems to last for a long while. At least its potential in terms of core clock frequencies increase is far from being exhausted that is why Intel will not give it up even when the CPU family moves to 0.09micron manufacturing process. As they confirmed at IDF, the next processor core to come after Northwood will be Prescott made with 0.09micron technology.

Prescott launch is scheduled for H2’03. However, by the end of this year Intel is going to start shipping the first samples of the Pentium 4 processor built on the new core to its closest partners. Pentium 4 family is expected to reach 5-6GHz core clock due to the fine 0.09micron technology used. In fact, Intel is going to use Prescott core not only in desktop processors, but also in mobile and server CPUs. The Prescott modification developed for the server market is also known as Nocona.

Although Prescott core will be based on NetBurst architecture, Intel is planning some enhancements aimed at increasing the Pentium 4 performance significantly. First of all, Prescott based processors will support HyperThreading technology, which is now implemented only in server CPUs on Prestonia core. Due to HyperThreading Pentium 4 (Prescott) processors will act like dual-processor systems thus increasing the performance in multi-threading tasks by 15%-30%. Also Pentium4 (Prescott) will use a faster Quad Pumped Bus working at 533MHz, and then at 667MHz.

We also have some info (proven by Intel as well) that Prescott may also support Yamhill technology, which will allow these CPUs to process 64bit codes. However, Intel will finalize its decision about including or not including Yamhill technology into the upcoming Prescott core a bit later, depending on the success of the coming AMD Hammer competitors.

To support Pentium 4 (Prescott) CPUs Intel is planning to launch a corresponding chipset for it aka Springdale in 2003.
