Sorry, but how can you state definitievely that the Tegra3 is "severely underpowered" when you have no data to support that statement other than what you see on screen.
I would contend that the majority of lagginess is either due in part to 3G connectivity and/or a some dependencies/multithreading in the software that remain to be ironed out.
Lets say you put a processor in that is twice as powerful, your one second delay becomes 0.5sec and is obviously still laggy albeit slightly less so.
As an example, some versions of Android are noticeably more laggy than others in some parts of the software, yet my N5 processor remains unchanged.
It's very much the case of the Tegra3 being underpowered. Benchmarks aren't always the best metric as each piece of software behaves differently but look at these two devices which have identical hardware, aside from one using a Tegra3 for non-US markets and the other using a Qualcomm 8960 for US:
HTC One X (Tegra 3) Review - Performance
HTC One X (MSM8960) Review - Performance
Tegra3 clocks in at 3540 vs QC's 6131 on IceStorm, when driving a large panel like on the Model S having enough GPU oomph is going to make a large difference in the fluidity of your software.
That said Telsa has done a pretty good job of wirnging performance out of the chip and I don't have any major complaints although it is disappointing to see hitches in parts of the experience.
