Intel® 45nm (nanometer) processor brings new enhancements to the Intel® Core™ Microarchitecture with double the transistor density over Intel® 65nm processors, 20% improvements in transistor switching speed and 30% reduction in switching power. Resulting benefits are higher frequencies and larger cache sizes within the same power and thermal design as the 65nm processors, with new SSE4 (Streaming SIMD Extensions) multimedia instructions for improved multimedia playbacks and enhanced video encoding and decoding.

Shuttle’s current entire Intel platform barebones based on the Bearlake platform (Intel® X38, P35, G33 and G31 Express Chipset) supports the latest Intel® 45nm processors, delivering higher performance and increased energy efficiency whilst still on the same Thermal Design Power (TDP).
