According to the latest white paper for AMD?s CPU, the frequency multiplier for the upcoming 65nm products included AMD Athlon 64 FX, AMD Athlon X2 (Brisbane) and AMD Sempron (Sparta) have been changed to 0.5x. The integral multiplier limited a 200MHz (by Hyper-Transport Bus) separation between each existing model. The change of the multiplier could lower the separation to 100MHz, making the product line be more flexible. AMD used to enrich the product line by different size of L2 cache. With response to the Intel price cut on July 23, AMD plans to terminate the production on large L2 cache model such as Athlon 64 X2 4000+ (2GHz), 4400+ (2.2GHz) and 4800+ (2.4GHz). The new multiplier is a way to help AMD to enrich its product line, filling the gap of the terminated models.
