No 64-bit Intel Mobile Chip Yet

At Intel’s Wireless and Mobility Press Day on Thursday, June 2, 2005, Mooly Eden – vice president and general manager of the company’s mobile platforms group – described the company’s next generation notebook technology, code-named Napa. Basically, Napa’s centerpiece: Intel’s coming Yonah mobile processor- the company’s first dual-core CPU for notebooks.

In other words, Napa is the code name for the combination of Yonah, a new mobile chipset, and a new wireless chip that makes up the Centrino brand. It can be said as the next centrino-like technology.

Yonah is the code name for the dual-core version of Intel’s Pentium M processor for notebooks, scheduled for release in the first quarter of next year. Unlike Intel’s first dual-core designs for desktop PCs, Yonah is a much more integrated design that shares storage and power management resources within the chip. 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.

Unlike the dual-core desktop chips we’re seeing now, Yonah will be a 32-bit CPU. So it sounds like Intel won’t have a 64-bit notebook CPU at Longhorn’s launch, which is around the time Napa’s launch.
