2005-04-14 AMD Newark / Lancaster / Georgetown / Sonora Mobile AMD64 chips with 1MB of L2 cache built in a Socket 754 format. A low power version of Lancaster rated at 25 W may be planned for 2005-Q3. Replaces Oakville and Dublin.
2006-01-05 Intel Yonah Mobile chip, succeeding Dothan in the power optimized notebook segment including HyperThreading and Vanderpool. Will use the Alviso-GM chipset. Includes one (Yonah1 - Core Solo) or two (Yonah2 - Core Duo) Dothan cores with one shared 2MB cache. The cache is dynamically divided between the cores. Runs on a 667 MHz bus, except for the ULV version which uses 533 MHz. Earlier listed as a 90nm chip in 04-H2.
Yonah (sometimes referred to as Jonah) is part of the Napa Centrino platform, succeeding Sonoma.
Named X50: $637, X40: $423, X30: $294, and X20: $241, while X48 and X39 will be low voltage versions.
There will also be a low-end Yonah called 756, below X20, with only one core running at 1.67 GHz and 2MB of cache.
Yonah will be used in future Macs.
Newer info names the chips T2600, T2500, T2400 and T2300 for normal chips, L2400 and L2300 for Low Voltage and U1400 and U1300 for Ultra Low Voltage. Clocked from 1.06 to 2.16 GHz.
2006-07-27 Intel Merom Mobile processor succeeding Prescott-M and Yonah built on a 65 nm process. Accompanied by the Crestine chipset. Recent rumours claim that Merom is a major new core design with multiple cores and, depending on version, 2-4 MB of cache, which will also form the base for the next desktop chip, Conroe. Said to consume about 45W.
Earlier said to launch in 05-H2 or 2007, prototype chips has been out since May of 2006.
Merom is part of the Santa Rosa Centrino platform, succeeding Napa. Said to be used in future Macs.
Bus speed to go up to 800 MHz in 2007-H1.
Will be named T7600, the T7400, the T7200 and T5600.
2006-H2 Intel 965GM Mobile chipset for Merom, succeeding Alviso / Calistoga.
Have earlier been called Crestine. Will include DirectX10 graphics capabilities in the Graphics Media Accelerator 3000 core (probably by microcode update). Part of the Averill platform.
