"as we can see hsr without high mhz wont cut it"
not so true, it is Tile based rendering without mhz will compete well, however will not dominate. the kyro competes well for a TNT2/Voodoo 3 era chip (which is what it is), had it been clocked slightly faster, it would be competing well with TODAYS chips.
slightly being about 166mhz mem/core. that's nothing compared to todays V5, and Geforce 2 Ultra in terms of sheer power, but it DOES cut it in terms of performance.
