Are you able to find the answer to your question, hints:
ATi and Microsoft make 100% correct statements regarding:
"operations per second"
and
"floating-point ops per cycle"
Why won't they ever claim more than 48 billion shader ops per second? Take notice of metrics and clockrate. I think it's bad to mislead consumers like this, but all official specs sheets are still correct, 48 billion shader ops/s just like Microsoft announced.
