Merom is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M based Yonah processor. Merom has product code 80537, which is shared with Merom-2M and Merom-L that are very similar but have a smaller L2 cache. Merom-L has only one processor core and a different CPUID model. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom was manufactured in a 65 nanometer process, and was succeeded by Penryn, a 45 nm version of the Merom architecture. Together, Penryn and Merom represented the first 'tick-tock' in Intel's manufacturing paradigm, in which Penryn was the 'tick' (new process) to Merom's 'tock' (new architecture).
Merom, the first mobile version of the Core 2, was officially released on July 27, 2006 but quietly began shipping to PC manufacturers in mid-July alongside Conroe. Merom became Intel's premier line of mobile processors, with mostly the same features of Conroe, but with more emphasis on low power consumption to enhance notebook battery life. Merom-based Core 2 Duo provides a slight performance increase associated with 3D rendering and media encoding tasks [1], yet maintains the same battery life as the Yonah-based Core Duo. Merom is the first Intel mobile processor to feature Intel 64 architecture.
