Details emerged on Intel dual-core mobile chip

Some more details have emerged on the new Intel dual-core mobile chip. "Yonah" (code name for the dual-core version of Intel's Pentium M processor for notebooks) will have two cores, which will share a single, common bank of cache memory. It is scheduled for release in the first quarter of next year.

The just-released dual-core Pentium D processor uses separate 1M-byte cache memory banks dedicated to each core. In the Yonah processor, a single 2M-byte cache memory bank is available to both cores, reducing the chance that data will have to leave the chip to be temporarily stored in a system's main memory bank.

Intel claims that the battery life of notebooks based on a Yonah processor will exceed that of the current generation of Intel's Centrino technology.

I hear talk about how to best retrofit current software to take advantage of these dual processors. Rather than make it complicated, why not just let the earth's largest CPU resource hog, Windows, have one processor all to itself, and run your apps in a clean CPU... of course, you'll still have to fight for a tiny bit of disk bandwith occasionally, between the myriad of disk checkers, virus scanners, etc. running on the other CPU.This will become more important when M$ rolls out Wronghorn (as my Japanese friend calls it) in the near future...
