The Turion X2 Ultra is a dual-core processor fabricated on 65 nm technology using 300 mm SOI wafers. It supports DDR2-800 SO-DIMMs and features a DRAM prefetcher to improve performance and a mobile-enhanced northbridge (memory controller, HyperTransport controller, and crossbar switch). Each processor core comes with 1 MiB L2 cache for a total of 2 MiB L2 cache for the entire processor. This is double the L2 cache found on the Turion 64 X2 processor. Clock rates range from 2.0 GHz to 2.4 GHz, and thermal design power (TDP) range from 32 watts to 35 watts.
