SPEs don't count as cores SPEs=/= cores. I just gave the regor as an example, consoles use old technology even for their time, eg the new WIi U is going to be using a graphics card 2 generations (by the time it is released 3 generations!) old. The reason for the sales of the systems for use in parallel as supercomputers is because Sony was selling the PS3s at a price at which they weren't making a profit (they were through game sales and PSn sales, but the not console sales in order to compete with the 360 and WIi pricing) hence the rise in use as supercomputers. As I said before it's not the processing power that makes the system able to handle data it's the efficient architecture, (same reason why sandy bridge (dual core up to octathreaded (4c/8t)) beats even the (6-core) thuban series).
