Intel started shipping the Xeon DP 5000 series Dempsey dual-core server processors. They feature the LGA771 interconnect and 4MB L2 cache.
The processors were first shown in public almost a year ago and come a month before the next-generation architecture Xeon - aka 'Woodcrest' - is due to launch.
Eight CPUs comprise the 5000 series line-up, clocked from 2.5GHz up to 3.73GHz. The first four processors - the 5020, 5030, 5040 and 5050 all run on a 667MHz frontside bus and have a 95W thermal envelope.
The remainder - the 5060, 6063, 5070 and 5080 - operate across a 1066MHz frontside bus. According to Intel's website, all but the 5063 have a 130W maximum power draw - the 5063 is a 95W part. The 5060 and 5063 are both clocked at 3.2GHz.
