Mach V/Kansas uses a 100 MHz "inline" L2 cache resident on the daughtercard instead of the 50 MHz look-aside cache of the PowerSurge/Tsunami/TNT boards. This probably helps. If the L2 cache were arranged like the G3 and operated at speeds like the G3 (1/2 to 1/3 the processor speed), there is no doubt that 604ev (also sometimes labeled as 604er if you listen to IBM) CPUs would have been serious competitors for years to come after introduction.
