Tom heeft een aantal AMD 750 Super Bypass benchmarks aan zijn KX133 review toegevoegd. De resultaten scheppen hetzelfde beeld als de benchmarks uit de reviews van SlotA.com en AnandTech: de AMD 750 met Super Bypass enabled komt dicht in de buurt van de KX133. Wel bleek dat de KX133 dankzij AGP4x duidelijk beter presteerde in de professionele SPECviewperf OpenGL benchmarks:
I hope all the upset souls have finally calmed down. 'Super bypass' is certainly an important feature for Irongate, but it's not making a Porsche out of a Chevy. Anyone who is in the process of buying an Athlon-system or platform should make sure that it carries the KX133-chipset. It's a matter of fact that Irongate has just become obsolete. This may be a bitter pill to swallow for all Irongate-owners, but those should please appreciate that in the PC-world there's always something better and faster around the corner. Changing from Irongate to KX133 is a rather questionable move though. Unless you are using OpenGL development software you might want to wait until the next Athlon-chipset that supports DDR-SDRAM.
