If you follow each graphic card from the year dot to now then no, gflops and tflops aren't a lie.
Of course if you invoke PC entry level graphic cards that have been purposely limited to make a whole tier they don't fare well at the bottom end.
Thing is this big tflop thing is not even about PC tiered specs vs console, the brute forcing as he puts it and budgets of console vs PC and bang for buck of consoles, it's console fans comparing two consoles, that would by his logic, be equipped to last.
XBX is the more powerful console than the Pro. If MS wanted to gimp it they could have but they generally don't and tflops with specs in line with it results in a big difference in performance across many titles, hence why tflops are a big talking point.
