Motherboard Intel P35 Memory Performance: A Closer Look

AnandTech attempts to figure out what the Intel P35 chipset's secert sauce is made of.

In our recent DDR3 vs. DDR2 review we discovered a 16% to 18% improvement in memory bandwidth with the P35 chipset. This translated into a 2% to 5% increase in real world performance in some computer applications. This represents a significant improvement in performance. Our review attributed the increase to the P35 memory controller, as we found no real difference in the performance of DDR3 and DDR2 on the new P35 chipset. Both memory types were much faster on P35.

In the review we attributed the performance increase to the P35, rather than the DDR3 memory. Technically this is correct, but there are two components at play in the performance increase. First the P35 memory controller itself is improved to provide better memory performance at the same memory speed and timings, and second the chipset supports the 1333 FSB which also improves memory performance. Since many readers have asked which is the primary factor in the memory performance increases - architecture or bus speed increase - benchmarks were set up to try to separate the impact of the memory controller improvement and the bus speed increase on P35.

2-5% is significant?

Whoops, I just realized this that particular news thread did not get nuked. Caveman-jim, I will merge your post with the previous thread.
