Benchmarks for ATI's TRUFORM Technology?

SanLouBlues asks: "I'm slow and still deciding on what video card to get, but it's caused me to wonder what the performance of ATI's TRUFORM n-patching is like. I've heard plenty of subjective comments and seen the pictures, but despite my best efforts, no benchmarks. I would hope that similar benchmarks would be available for GeForce3s since I believe ATI claims that n-patching is part of DirectX."
