@rygorous @mogwai_poet I'm not so sure about that. The paper mentions a peak of 240 Mpx/s, which is almost exactly what a TNT2 could do. A GeForce2 is roughly 4x as fast, in terms of raw throughput.
The only thing that sets the RealityEngine apart is the absolutely unhinged memory size and bandwidth, which could afford them things like always-on MSAA, and the extremely overpowered geometry processing stage.
