200 MHz more than 800 MHz is a 25% increase.
200 MHz less than 1000 MHz is a 20% decrease.
Original poster about speed increase was correct.
Agreed, your math and astute observation of the completely obvious is to be commended.
I think I said there is a 20% difference. Is that not what the OP asked? What is the difference? And I would bear out that in real life, the performance
increase would be a lot closer to 20% than 25%. And still, it's kind of irrelevant to bicker over something we have yet to compile all the facts.
