2005-03-29 Intel E8500 Server chipset made to accompany the 4-processor server (4S) chips Cranford, Potomac and later Paxville and Tulsa. Said to support PCI Express, Serial ATA and DDR-II. Also known as Twin Castle 4S.
2005-03-29 Intel Potomac Prescott based chip for 4- and 8-processor servers. Will have the EM64T bit extensions. Starts at 3.33 GHz and includes 8 MB of L3 cache. Uses the Twin Castle chipset. Part of the Truland platform
2006-01-05 Intel Presler 65 nm chip dual core chip including Vanderpool (a virtualization technology) to succeed Smithfield. Likely to run at 3.6 GHz and above. Previously known as Blue Pressler. Is in fact two Cedar Mill chips bonded together. Uses the i975X chipset.
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.
