Penryn (microprocessor)
open-in-new
<p>Penryn is the code name of a mobile processor from <a href="/facts/Intel/SMF0gJJX">Intel</a> that is sold in varying configurations such as <a href="/facts/Core_2/9gJP9o8p">Core 2</a> Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron. </p><p>During development, Penryn was the Intel code name for the 2007/2008 "Tick" of Intel's <a href="/facts/Intel_Tick-Tock/CeKPeLur">Tick-Tock</a> cycle which shrunk <a href="/facts/Merom_(microprocessor)/JoR4YQNS">Merom</a> to 45 nanometers as CPUID model 23. The term "Penryn" is sometimes used to refer to all 45 nm chips with the <a href="/facts/Core_(microarchitecture)/fuKkuVsP">Core</a> architecture. </p><p>Chips with Penryn architecture come in two sizes, with 6 MB and 3 MB L2 cache. </p><p>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. </p><p>The desktop version of Penryn is <a href="/facts/Wolfdale_(microprocessor)/m9aFgKmz">Wolfdale</a> and the dual-socket server version is <a href="/facts/Wolfdale-DP_(microprocessor)/j1M8Hp6D">Wolfdale-DP</a>. Penryn-QC is related to <a href="/facts/Yorkfield_(microprocessor)/5PcpyJaY">Yorkfield</a> on the desktop and <a href="/facts/Harpertown_(microprocessor)/j1M8Hp6D">Harpertown</a> in servers. The MP server <a href="/facts/Dunnington_(microprocessor)/j1M8Hp6D">Dunnington</a> chip is a more distant relative based on a different chip but using the same 45 nm Core microarchitecture. </p><p>Penryn was replaced by the <a href="/facts/Nehalem_(microarchitecture)/UPsI457h">Nehalem</a>-based <a href="/facts/Arrandale_(microprocessor)/8CsvVMyq">Arrandale</a> (dual core) and <a href="/facts/Clarksfield_(microprocessor)/Vdl0t0Jz">Clarksfield</a> (quad core). </p>
