Intel goes to great pains to insure all of the buses are fully utilized. On a 64-bit machine, all of the data paths from RAM up to the L1 operand cache will be able to move twice the number of items per cycle when the items are only 32 bits wide. Between the L1 cache and the superscalar execution core, there may be less of a gain, but since the core contains three ALUs and separate load and store sections to service them, memory operations are combined wherever possible to get data in and out as fast as possible. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
