The fact that he only mentions the PS2 when, again, it was the weakest console of its generation pretty much shows that. If the PS2 was better than PCs, then the Gamecube and Xbox would have been supercomputers (and I mean, they were pretty expensive, but not that expensive). Nvidia has never had much stake in the console market, so it wouldn't be surprising for someone from there to not really know the specifics, especially ten years down the line.
What the PS2 did have was a unique processor that had two vector units, and one of those vector units could work independently of the rest of the CPU. It allowed it a loophole that could wiggle around the fact that it didn't have the same raw horsepower (because, to be honest, raw power isn't everything). It also had dedicated memory on the GPU which was faster than the Gamecube or Xbox, but couldn't cache as much. The PS2's GPU also was the only one that didn't have a unit to support "transform & lighting":
Now, if your argument is that the PS2 was a better investment in terms of performance than a PC of the same price at the time, then you may be correct. That's a pattern which has always been relatively true with regards to PC gaming. A $300 PC in 2001 may very well have been slower than the PS2, particularly because the chances are it wouldn't have been built specifically for playing games.Transformation is the task of producing a two-dimensional view of a three-dimensional scene.

Lighting is the task of altering the colour of the various surfaces of the scene on the basis of lighting information.
