Penryn is the code name of a processor from Intel that is sold in varying configurations as Core 2 Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron.
During development, Penryn was the Intel code name for the 2007/2008 "Tick" of Intel's cycle which shrunk Merom to 45 nanometers as CPUID model 23. The term Penryn is sometimes used to refer to all 45 nm chips with the Core architecture.
Chips with Penryn architecture come in two sizes, with 6 MiB and 3 MiB L2 cache.
Low power versions of Penryn are known as the Penryn-L, these are single-core processors. The Penryn-QC quad-cores are made from two chips with two cores and 6 MB of cache per chip.
The desktop version of Penryn is Wolfdale and the dual-socket server version is Wolfdale-DP. Penryn-QC is related to Yorkfield on the desktop and Harpertown in servers. The MP server Dunnington chip is a more distant relative based on a different chip but using the same 45 nm Core microarchitecture.
Penryn was replaced by the Nehalem based Arrandale (dual core) and Clarksfield (quad core).
The successor to the Merom core for the Core 2 Duo T5000/T7000 series mobile processors, code-named Penryn, debuted on the 45 nanometer process. Many details about Penryn appeared at the April 2007 Intel Developer Forum.
Important advances include the addition of new instructions including SSE4 (also known as Penryn New Instructions) and new fabrication materials; most significantly a hafnium-based high-k dielectric.
