Recently, AMD laid out a plan for the Turion64 and the mobile variant of the Athlon64 to be shown the world of dual channel MMC. Both of these chips already feature the fast on-chip MMC that greatly benefits the entire A64 line, and AMD hopes to step up performance a considerable amount by also making that MMC capable of dual channel addressing. This would result in a few architectural changes, including a large increase in the number of pins for the CPU, but the performance benefit would outweigh the downsides. With the low pin count of the S1 socket set to be used for the next gen mobile Athlons, it's possible AMD will have two mobile lineups, though AMD has not released more particulars as of yet.
