Yonah has been officially named Core with Duo or Solo following the prefix, indicating whether or not it's a dual-core setup. In terms of processor nomenclature, Intel has changed the convention again by selecting letters followed by 4-digit codes. The new processor names are as follows: T1300, T2500, L2500... T followed by 2xxx signals dual-core while T followed by 1xxx signals single core. Lxxxx are the low voltage processors with their TDP at 15W compared to 31W for the T2xxx series.

The new mobile platform is codenamed Napa. The brand Centrino has been retained even though the logo has been modified slightly while Intels logo has gone through a complete shift. It is no longer Intel Inside but Leaping Ahead. If no one else, Intel's new partner Apple surely believes that Intel has been trapped inside for a bit too long.

Before we proceed towards the notebook itself, lets take a look at what Core Duo is all about.

When Intel appeared on the stage to talk about its products, the main focus was on making processors frugal in terms of power utilization. Intel finally came to its senses and accepted that core speed was not the only way to increase system performance (something AMD had been harping about for years). Yonah gives us an excellent opportunity to not only study Intels latest attempt at revamping the mobile platform, but also the way we think about mobility forever. It also gives us the opportunity to make a guesstimate on Merom's performance when it's launched later this year.

Socket:

Interestingly, Intel has changed the socket configuration yet again. This could be due to the architectural changes changes that require you to use the newer 945 boards. While the pin count has remained the same, Intel has changed the pin layout, making it imperative that any notebook featuring Core Duo will be running on the all new 945 chipset. The socket will be based on a 479-pin layout, and as mentioned earlier, the pin arrangement has been changed, so obviously you can't put in newer processors in old sockets. Surprisingly though, the Core Duo processors have not migrated to the LGA775 kind of a pinless design. The Core Duo and Solo still have pins on them, which does seem to be a bit strange.
