Intel spills beans on Yonah, the next notebook chip

[notoriousformula]

AN FRANCISCO--Yonah, a notebook chip coming from Intel in the first part of next year, is going to be a lot different than its predecessors, company executives say.

The chip, which will be made on the 65-nanometer process, will come with a number of enhancements over the current Pentium M line of notebook chips, Mooly Eden, vice president of the mobility group, said at a briefing here.

For one thing, it will contain two cores, instead of the single core on current notebook chips. The two separate cores will also share a 2MB cache. Current dual-core desktop chips from Advanced Micro Devices and Intel come with similar sized caches, but each core accesses only 1MB of cache memory dedicated to it. Sharing the cache will significantly boost performance. (The chips communicate with the cache through a single bus embedded in the chip.)
