    "Én meg igen."

    Az ilyen rendkívül informatív válaszok helyett lehetne pl. keresni egy egyszerű kis linkecskét. pl. : http://en.wikipedia.org/wiki/Cell_(microprocessor)#Power_Processor_Element
    Ebből rögtön kiderül, hogy én emélkeztem rosszul, és így elkerülhető a felesleges vita.

    Mellesleg ugyanitt írják:
    Compared to a modern personal computer, the relatively high overall floating point performance of a Cell processor seemingly dwarfs the abilities of the SIMD unit in desktop CPUs like the Pentium 4 and the Athlon 64. But, comparing only floating point abilities of a system is a one-dimensional and application-specific metric. Unlike a Cell processor, such desktop CPUs are more suited to the general purpose software usually run on personal computers. Also, Cell is optimized for single-precision calculations; for double-precision, as used in personal computers, Cell performance drops by an order of magnitude to levels similar to desktops.
