Penryn: 45-nm next generation Intel® core™ 2 processor

This paper describes Penryn (codename), Intel–s next generation family of processors implemented in a 45nm High-k metal gate silicon process technology and designed to meet a wide range of power envelopes and market segments. It is a dual-core, 64-bit CPU based on the Core™ microarchitecture with a unified 24-way L2 cache of 6MB. Key new features in Penryn include a Fast Radix- 16 Divider, an SSE4 instruction set, a radically new Power Management state (Deep Power Down) and Enhanced Dynamic Acceleration Technology (EDAT). Active and leakage power reduction techniques are used throughout the design to reduce power consumption while not compromising the scalability requirements. The chip is offered in various package technologies including a MCP version for the Quad-core products.
