The following table lists the formal specifications of Intel’s and AMD’s processors for notebooks:
Intel’s Core Duo series includes four models with clock rates ranging from 1.66 to 2.16GHz. A speedier, 2.33GHz model will be added in the second half of the year. There also exist two economical Core Duo models clocked at 1.5 and 1.66GHz. Looking somewhat oddly among dual-core solutions, the 1.66GHz Core Solo processor also belongs to this series. Despite the different name, this processor is a regular Yonah, but with one disabled core. Do not mistake the Core Solo for an analog of the Celeron. The Solo is not a value processor; it is just targeted at applications that do not require multi-threading, but it retains all the strong points of the Core Duo architecture. We don’t think the Core Solo will be very popular because Intel currently compensates the disabled core with a too small price reduction, by 15%.
And finally the CPU rating system Intel uses for its Core Duo processors should be described. Instead of a 3-digit number typical of Pentium 4, Pentium M and Pentium D, the new series of mobile processors employs a new marking system.
The new Core Duo and Core Solo mobile processors are marked with an index consisting of one letter and four digits. Strange though it seems, the new indexing system resembles the rating system of AMD’s mobile processor Turion 64. In the name of a Core Duo or Core Solo processor, the letter denotes a power consumption class (Intel mentions three possible variants so far: U stands for Ultra Low Voltage, L for Low Voltage, and T means an ordinary processor), and the 3-digit combination indicates the processor’s performance level within its class.
