Intel has shipped more than 1m quad-core Xeon 5300 microprocessors since introducing them in November 2006, meeting a goal announced by company executives earlier this year.
Intel's quad-core Xeon 5300 series, also known by the code name Clovertown, was released last November. The chips helped lead the company's recovery in the server chip market, taking share away from rival Advanced MicroDevices (AMD).
Intel has priced the Xeon 5300 aggressively, hoping to win more orders for its quad-core line.
The prices overlap those of Woodcrest, the code name of Intel's dual-core Xeon 5100 series. For example, Intel's Xeon E5345, which has 8M bytes of cache and four 2.33GHz cores, is the second-fastest Clovertown chip and is priced at $851 (£423) in 1,000-unit quantities, a standard pricing measure. That's the same price as the Xeon 5160, the fastest Woodcrest chip, which has 4M bytes of cache and two 3GHz cores.
Pricing for the entire Clovertown line ranges from $455 (£226) to $1,172 (£583), while the Woodcrest line prices range from $209 (£104) to $851 (£423), according to Intel's latest processor price list.
