3D Gaming Benchmarks
In Quake3 Irongate can logically not reach the performance of KX133. Irongate is damned to run AGP1x.
Quake 2 doesn't seem to be particularly impressed by 'super bypass', so the lead of KX133 still remains.
Super bypass is able to give Irongate a boost in Descent3, but it's not enough to reach KX133.
The same story is valid for Expendable. Super bypass makes Irongate faster, but KX133 can retain its lead.
