this is how it is broken down in Xbox 360 -

IBM PowerPC triple-core 'Xenon' CPU:
115 Gflops

ATI 'Xenos' graphics processor:
240 Gflops (programmable) + 697 Gflops (non-programmable)

total: 1052 Gflops (slightly more than 1 Teraflop )

is Xbox 360 as powerful as a 1 TFLOP Supercomputer ? no bloody way in hell.

a 1 TFLOP supercomputer has all of that computer power from general purpose
CPUs, plus the memory and memory-architecture to support that. Xbox 360
has roughly 1/10th of a Teraflop (115 Gflops) from its CPU, and that is only
peak theoretical single precision flops. the rest of the flops performance
in Xbox 360 is in its ATI GPU, and most of that is put into hardwired
GPU-functions, only about 240 Gflops is accessible to the programmer for
whatever graphics work he wants to program.

as for the Playstation3, Sony and Nvidia claim 2.18 Teraflops. well like
Xbox 360, the PS3 gets most of its flops performance from the GPU. in PS3's
case, that's 1.8 Tflops. the Cell CPU only has 218 Gflops, less than
twice as much as Xbox 360 CPU (115 Gflops).

so neither Xbox 360 nor PS3 are true Teraflop machines, as far as real
CPU-based flops performance is concerned, which REAL supercomputers have.

hmmmm, very intresting.

didn't understand a word of it :-)

Ah, that's not your fault though. It's because it's meaningless babble.

English translation:

Hey, look. Microsoft are using meaningless statistics as a marketing tool.

Wow, and so are Sony.

In other news, pigs found not to fly.
