    AMD sockets. They support that 2-3 generations with a single socket, allowing you to do such upgrades between generations.

    There is however a limit to how much performance one can squeeze out of a device without having to adjust the external interfaces. It will be most interesting to see what the next generation of AM1 socketed chips will look like.
    Dual-channel RAM is not that much of a limit. Consider socket 754, a previous single-channel AMD socket. Compare one of the last cpus for that, Athlon 64 3700+, a single-core made on 130nm in 2005 - it beats the 5350 by 5% in integer math single-threaded.

    If a core with that outdated tech can beat it, using comparable external interfaces, there can easily be a doubling of performance using the AM1 socket.

      Since when is integer math performance limited by memory bandwidth? You may want to come up with better arguments.

      The 2.4GHz single core Athlon 64 3700+ built on SOI process had a 89W TDP (not counting Northbridge and Southbridge) according to Wikipedia. The 2.05GHz Athlon 5350 is a quad-core SoC built on TSMC bulk process that has a 25W TDP. Somewhere, compromises have to be made.

      The "external interface" of Socket 754 is not at all comparable to the AM1 platform.

        CPU performance was the topic, not memory-bound tasks. So integer perf is entirely relevant.
