AMD AM2 4200+ Vs. AMD 939 4200+ CPU'sBosco -
PCMark05, released by Futuremark, provides us tests similar to those of Sisoft Sandra, but rather, focuses on File decompression and encoding. Results are again below.
As seen above, the AM2 flavor of the 4200+ actually pulled slightly ahead on decompression, encryption, and scanning. This is not especially a surprise, as it can be partially accredited to the move up to DDR2 memory.
