What is 45nm Next Generation Intel® Core™2 Processor Family (Penryn)?
The 45nm Next Generation Intel Core 2 processor family (Penryn) is the next generation of Intel processors based on Intel® 45nm transistor technology, a new transistor breakthrough that allows for processors with nearly twice the transistor density and drastically reduced electrical leakage. Penryn includes new instructions (Intel SSE4) and microarchitecture enhancements that will deliver superior performance and energy-efficiency while maintaining compatibility to already existing applications. For developers, this means improved performance and energy-efficiency for existing software, and the opportunity to further optimize software to take full advantage of Intel SSE4 and the microarchitecture enhancements available in Penryn.
