    I think we are starting to run out of space. whats after 28nm? you can only get so small before technology has to change to another format

    Picometer comes after nanometer :p

    Next step is 3D designs. Current chips are designed as a massive drawing on sheet of silicon. Though they are layered to allow connections to cross without leakage they are stillessentially a drawing on silicon.

    The next major change will be layering the current flat designs one on top of another with vertical interconnects.

    There are a few projects working on it, but not much is being said about the progress toward 3D chip design.

    sooner or later we'll be talking about putting a whole processor on a single silicon atom XD. exactly how small is a picometer anyways?

    well for starters, there goes 1000 um on a millimeter and there goes 1000 nanometer on a µm. so we are talking pretty d*** small here

    :confused: Why is this new? AMD and IBM have been working together for ages* in IBM's east fishkill facility...

    *well...ever since the AMD-Motorola alliance was cancelled

    so is amd skipping 32nm? pretty sure intel will follow through with it which by their calendar won't have 28nm till late 2011

    32 to 28 isn't exactly a huge leap...

    Ive said it before, Ill say it again

    People underestimate the technical accomplishment of '45nm' or '32nm' etc. The closer we get to 16nm the more in awe I am.

    We will be looking at (pseudo) 3D chips at 22nm and more of Mott's 'Strange Metals' will be used instead of SiO2. 28 is 'simply' a refinement of the 32 materials and synthesis techniques.

    no doubt.. and you'd think the overclocking would be worse at a certain point from leakage

    28nm is a half node to 22nm. You are unlikely to see 28nm used in CPUs, AMD's next die shrink will be 32nm as per their roadmap.
