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.

The first 22nm IA multi-CPU and GPU system-on-chip using tri-gate transistors

This paper will go over some of the details of Intels latest Core offering, the first 22nm design code-named Ivy Bridge. In addition to the new process, Ivy Bridge offers several new features including significant improvements to the Graphics and Media block including DX11 support, new power/thermal control optimizations, support for 3 simultaneous displays, new security features and new PCIE Gen3 support. The new 22nm process provides exceptional low voltage performance advantage as well as a 2x improvement in density. The paper also reviews changes to leverage the low operating voltages as well as details of IO, PLL and clocking. Ivy Bridge was introduced into the market on April 23, 2012.
