Scumbria, Re: K7 vs Xeon's I will throw out this question to you and onayone else who might know. In comparing the price/performance ratio's of the K7 vs Xeon. Let's assume that K7 is 30-40% faster than equivalently clocked Xeon. The AMD's will use interleaved memory as I understand it. Does that mean for a server that one needs 2x this memory for K7. It would seem to me that for a server with 1Gb of RAM that if it needs 2x that memory for K7. This would eliminate any K7 price/performance advantage would it not? I know folks who run up to 4Gb of main memory. So it would be much cheaper for somebody to get dual or even quad CPU's than dual memory for memory intensive servers. As regular DRAM moves to 133Mhz speeds the Xeon servers will gain performance with respect to a 200mhz K7 bus unless K7's will run at 266Mhz at that time. And once camino comes out with Rambus RDRAM then Xeon performance will gain again. So in Q3 when the battle starts it would appear to me that the total system costs may still be in the Xeons favor. Not a particularly appetizing scenario frankly. Regards, Kash Johal
