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.
