SiSoft Sandra (beta 8.21)

Since Sandra memory benchmark integrates internal data transfer to and from the caches and the ALU and FPU units as well as the AGP DMA it is a somewhat different approach. This doesn't mean that this is not a valid benchmark, however, it is not looking at the isolated memory bus / subsystem.

SiSoft Sandra ALU memory bandwidth

Er..., composite ALU memory bandwidth as shown by SiSoft Sandra 8.21 (beta)

SiSoft Sandra FPU memory bandwidth

Same as above but looking at the FPU (floating point) subsystem instead of the IEU (integer execution).

It is rather interesting to see how well the VIA KT266A holds its ground here, particularly in the area of ALU memory bandwidth. The internal 10 level integer pipeline of the Athlon can make a big difference when combined with a burst of 8 DDR protocol. The reasons for the lower FPU bandwidth are not entirely clear, though, however, it could be that the 15 stage pipeline to the FPU is counterproductive and hurts the overall bandwidth as measured by Sandra. Overall, in all memory bandwidth benchmarks, the i845 falls hopelessly behind the competition.
