Danny Cheung, an Intel Corporation spokesman in Singapore, announced that the millionth quad-core Xeon chip was shipped this month. The chip giant has unleashed more than 1 million quad-core Xeon 5300 microprocessors since introducing them last November, meeting a goal announced by company executives earlier this year. The Xeon 5300 series, which was code-named Clovertown, has been priced aggressively in an effort to win more orders for the quad-core devices. The prices it is charging overlap those of its dual-core Xeon 5100 series, which was code-named Woodcrest. According to Intel"s latest processor price list, pricing for the full Xeon 5300 line ranges from $455 to $1,172 in quantities of 1,000 chips, while Xeon 5100 pricing ranges from $209 to $851.
