LFCS: A $99 supercomputer

I'd really like to see a benchmark showing the 64 computing cell version to be faster than a cell phone GPU, at some practical real world tasks, before getting excited. 32KiB of RAM per node, subdivided into four 8KiB blocks is going to limit it to very specialized tasks. The total available ram is only 2MiB so forget physics modeling. On the other hand a PC's GPU these days has hundreds to thousands of times that RAM available.

That leaves the power argument. Again, a cell phone can't draw 5W. The battery wouldn't last long enough to be useful since most phones are lucky to have 5WHr of capacity, and that label rating valid if discharging in an hour anyway.
