The three versions of the Xeon MP, designed for servers using four or more processors, clock at 1.4GHz, 1.5GHz and 1.6GHz. The chips feature three levels of integrated cache memory, adding up to 1Mbyte of Level 3 cache to 8Kbytes of Level 1 and 256Kbytes of Level 2 cache.
The 1.4GHz and 1.5GHz Xeon MP processors each have 512Kbytes of Level 3 cache. The 1.6GHz Xeon MP has 1Mbyte of Level 3 cache.
Greater amounts of onboard memory get important data closer to the core of the chip, improving computational performance and permitting the processor to run more complicated programs, said Nathan Brookwood, a principal analyst for the Insight 64 technology market research firm.
The 32-bit Xeon MP chip does not compete against 64-bit processors like Intel's Itanium or others from Sun Microsystems, Compaq Computer or IBM, he said. But the Xeon isn't supposed to.
Intel "currently dominates the market for low-end entry level servers that are using the Pentium III and Pentium III Xeon processors", he said.
Other than the Tualatin design, companies using multiple processor servers for things like e-commerce transactions and Web activities haven't had a real technology advance, Brookwood said. "Even though the dotcom companies imploded, you have Internet traffic doubling every six months or so ... the only thing that gets people buying again is new technology."
Intel is hinting at a multiprocessor server design for Xeon using 16 processors, an announcement that could be made in the next couple of weeks, Brookwood said.
