Arrandale processors were sold under the Celeron, Pentium, Intel Core i3, Intel Core i5 and Intel Core i7 brand names, with only the Core i7 models using the full L3 cache and all features. Processors ending in E instead of M are embedded versions with support for PCIe bifurcation and ECC memory, while the regular mobile versions only support a single PCIe port and non-ECC memory. The Celeron versions of Arrandale have the smallest L3 cache of just 2 MB.5
