According to reviews, the larger 4 MB L2 cache vs. Conroe CPUs have improved capabilities over previous models with similar processor clock rates. At launch time, Intel's prices for the Core 2 Duo E6300 and E6400 processors were US$183 and US$224 each in quantities of 1000.

When yields improve, they may be replaced with versions that only have the cache amount needed on the die, to bring down manufacturing cost. Traditionally, CPUs of the same family with less cache simply have the unavailable cache disabled, since this allows parts that fail quality control to be sold at a lower rating. The mobile version of Conroe is Merom, the dual-socket server version is Woodcrest, and the quad-core desktop version is Kentsfield.Conroe was replaced by the 45 nm Wolfdale processor. Conroe-L has only one processor core and a new CPUID model. It has product code 80557, which is shared with Allendale and Conroe-L that are very similar but have a smaller L2 cache. It was the first desktop processor to be based on the Core microarchitecture, replacing the NetBurst microarchitecture based Cedar Mill processor. Conroe is the code name for many Intel processors sold as Core 2 Duo, Xeon, Pentium Dual-Core and Celeron.
