Intel and AMD unveil faster server chips

Both Intel and AMD have unveiled their latest server chip designs at this week’s International Solid State Circuits Conference in San Francisco.

Both Intel and AMD have unveiled their latest server chip designs at this week’s International Solid State Circuits Conference in San Francisco.

Intel has revealed Tulsa, a dual-core Xeon server chip expected in the second-half of the year.

The chip will run at 3.4GHz, which is faster than the 3GHz Xeon chip currently on the market. Tulsa comes with a 16Mbytes unified cache, which means that each of the cores can access data from the entire cache.

Currently, Intel and AMD dual-core chips use segregated caches, which can slow processing. Intel said this enhancement can improve processing on some applications by up to 10%.

AMD’s new Pacifica chip unveiled at the conference is designed for lower power consumption and comes with AMD's own virtualisation technology.

Virtualisation allows a chip to efficiently power multiple operating systems running at the same time.

Pacifica has two 512Kbytes caches – one for each of the cores. AMD is not expected to have a unified cache until next year.
