The reason for the E7500 was ram quantities, not ram quality. When this chip was developed, Ddr was a lot less expensive than Rdram. This was a major concern because these systems deploy with several gigs of ram. Also, network servers don’t need extreme performance from the ram, but they do need a lot of it. A network server often has large amounts of data stored in cache, which requires large banks of ram. The intended market for this chip is network servers, not research computers.
