A:Yes. The AMD Athlon 64 X2 Dual-Core processor design is true dual-core - with two CPU cores on one die. AMD’s dual-core architecture relies on advanced Direct Connect Architecture to supply each core with the memory and I/O bandwidth needed to maintain high performance per core. AMD’s on-chip integrated memory controller ensures that both cores have optimal access to the integrated memory controller and integrated HyperTransport™ links, so that performance scales well with the number of cores.

Our competitor’s dual-core processor, as illustrated in press coverage, relies on outdated front-side bus architecture to relay both memory and I/O traffic from the cores to the memory controller that resides outside the processor chip.


Q:What do AMD Athlon 64 processor model numbers represent?
A:Since frequency alone is not an accurate measure of performance, AMD model numbers are a simple, accurate representation of relative AMD processor performance based on industry-standard software benchmarks. The higher the model number, the better the overall software performance running on the processor. The “+” at the end of each model number indicates the added performance benefits delivered by the innovative AMD64 architecture, such as an integrated memory controller and HyperTransport technology. These two factors alone account for a significant improvement in performance.
