Pentium 4: Northwood and Xeon
The first Pentium 4 CPUs based on the 0.13 micron Northwood core are on offer in Japanese computer stores. These are offered as Pentium 4 2A with 2GHz clock frequency and 512KB L2 cache and are also used in the Socket-478 FC-PGA2.
However, the CPU is not yet widely available, it is currently only available in a single store. But it should only be a matter of time before it is available everywhere: After January 6, 2002 this should be the case. Then the price should go down, which is currently extremely high, because the Pentium 4 2A mentioned above currently costs around 460 US dollars. The Pentium 4 server processor, which is based on the Prestonia core, has also appeared on the shelves of some Japanese retailers. It looks exactly like its 0.18 micron companion. The only discernible difference between the Xeon (Prestonia core) 2 GHz and the Xeon (Foster core) is the manufacturing process, namely 0.13 and 0.18 microns and the size of the L2 cache (256 and 512KB). The new Xeon 2000DP costs around US $ 590 in Japan.
