Together, Penryn and Merom represented the first 'tick-tock' in Intel's Tick-Tock manufacturing paradigm, in which Penryn was the 'tick' (new process) to Merom's 'tock' (new architecture).Ĭeleron M (Socket M) and Celeron (Socket P) Merom was manufactured in a 65 nanometer process, and was succeeded by Penryn, a 45 nm version of the Merom architecture. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom-L has only one processor core and a different CPUID model. Merom has the product code 80537, which is shared with Merom-2M and Merom-L that are very similar but have a smaller L2 cache. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M-based Yonah processor. Merom is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron.
