Intel ships the new 0.13µ Xeon
After Intel presented the Northwood, the successor to the Willamette made in 0.13 micrometer technology, at the beginning of last week, its workstation counterpart is now available. The 0.13µ Xeon, also called Prestonia, has been shipping recently.
More performance compared to its predecessor , the Foster, should bring the new Xeon on the one hand through architectural innovations, on the other hand through higher clock rates. Like the Northwood , it is now manufactured using 0.13 micrometer technology instead of the 0.18µ previously achieved. The main architectural change is probably the enlarged level 2 cache. With 512KB it is now twice as large as before. As an advance over older Foster models, Intel also states the support for 'HyperThreading' technology. So it is theoretically possible for a single new Xeon to execute several computing threads at the same time. Since this technology is primarily intended for servers, but the Prestonia is not intended to be a server processor, its use is not recommended by Intel itself. Even if Windows XP and other software tailored to multiprocessor systems can theoretically gain up to 20% in performance through HyperThreading, this is probably not a decisive innovation with the Prestonia. The higher clock rates that are now possible appear much more important, the Prestonia is delivered with 1.8GHz, 2.0GHz and 2.2GHz. The new 2GHz Prestonia is distinguished from its predecessor with the same clock rate by the addition 'A GHA'. So its somewhat complicated name is 'Intel Xeon 2.0A GHA'. The three models are priced at $ 251, $ 417, and $ 615 in quantities of 1,000 pieces.
