Penryn is the code name of a mobile processor from Intel that is sold in varying configurations such 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 Tick-Tock 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 MB and 3 MB L2 cache.

Low power versions of Penryn are known as the Penryn-L; these are single-core processors.[1] 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).
