A GFLOP (or gigaflop) is a unit of processing speed for computers and processor chips. A gigaflop is one billion floating-point (numbers that include many decimal points) operations (calculations) a second.
3.78 Gflop/s per processor, maximal 121 Gflop/s http://www.top500.org/orsc/2006/primepwr
PlayStation 2 format games are either CD-ROM (blue or clear) or DVD-ROM (clear) and are rendered using a graphics synthesizer clocked at 147.456 MHz with a floating point performance of 6.2 Gflop/s along with a 2mb sound memory. Playstation 3 format games have only one medium which is Blu-Ray disk (BD-DVD) and are rendered using a graphics processing unit made by Nvidia, the RSX 550 clocked at 550MHz with a floating point performance of 1.8 Tflops/s along with its cell-based sound processing.

"Supercomputer" is a very vague name for a very powerful computer. If there were a more powerful type of computer than the ones you're thinking of, it would instantly be called a supercomputer.
