Sun is also in the works for a PCI Ultra (or so > have I heard). No, not the same speed. They use 64Mhz 64 bit PCI buss (and usualy some slots that are 33Mhz), that is 4 times faster. Plus the internal busses are faster. The bigger boxes has not one PCI buss, but several. Sun Enterprise 450 has 6 PCI busses... > Some high end workstations use 70ns memory, the same (or even slower) And often uses interleaving to get the speed up. If you realy need the speed, that is a diffrent thing.
