Pentium Dual Core SU2700 1.3GHz Game Requirement AnalysisPenryn-L does not actually seem to be a separate chip but only a version of Penryn-3M with a single core enabled. However, it has a separate product code of 80585. Penryn-L is used in the ultra-low voltage Core 2 SU3xxx, the standard voltage Celeron 9xx and the CULV Celeron 7xx and Pentium SU2xxx series. The Celeron versions have only 1 MB active L2 cache, Pentium versions have 2 MB.
