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.
