The Inquirer has seen Intel's latest roadmaps and says Intel is planning to use a new numbering system for its dual-core mobile Yonah processors:
The numbers are a mixture of an alphabetic prefix and a four digital suffix. E will stand for TDP power greater than 50W, T for power between 25W to 49W, L for power between 15W and 24W, and U for TDP power less than 14W.
The four digit suffix is related to performance, Intel has told its customers. A bigger number, Intel says will show more performance related features, with examples for Yonahs, due in Q1 of next year, being the T1600, the T1500, and the like. So a T1700 is a 65 nanometre 2.33GHz chip with 2MB of L2 cache and a 667MHz front side bus. A T1600 is a 2.16GHz version of the same thing. But a U1500 is a 1.06GHz ultra low voltage dual core chip.
