"There is no question that the benchmarks illustrated by both systems, represent some inspiring results. The question, does the performance of the A7M266 portray a compelling reason to replace your motherboard, memory, and CPU? Much of what you hear regarding this newer technology is marketing propaganda. For example, SDRAM manufacturers are naming their memory after the peak bandwidth, not bus frequency. PC1600 DDR SDRAM is really PC100 DDR SDRAM, because the 100MHz bus transfers two bits of data per wire per clock (double data rate), which yields 1600MB (1.6GB) per second over a 64-bit bus (eight bits per byte). PC2100 is really PC133 DDR SDRAM because 133MHz multiplied by two bits per clock multiplied by eight bytes equals 2100MB (2.1GB) per second. PC1600 and PC2100 coincidently sound more inspiring than PC100 or PC133."
