Scumbria, Re: I expect K7 MHz to ramp up quite quickly How will AMD handle the L2 cache issue ? Intel has to make their own for Xeon(400Mhz and up). Is there commodity SRAM readily available for say 350Mhz ? Gary

Scumbria, Your arguments seem to assume that K7 is stuck at 600 MHz. I expect K7 MHz to ramp up quite quickly. It is a new design, and appears to have had minimal speed work done so far. 1. I thought you said the K7 was all by-hand laid out. Wasn't that at least partially for speed optimization purposes? 2. Did Meyer talk about design rules for the K7, like rule of thumb maximum number of logic levels between latches, or clocks? You have always been impressed by the deepness of the pipeline in the K7, did they also keep it "short and sweet" between the latches? Tony

RE: <Your arguments seem to assume that K7 is stuck at 600 MHz. I expect K7 MHz to ramp up quite quickly. It is a new design, and appears to have had minimal speed work done so far.> Yes, you're right. There will be continued K7 frequency improvements. But probably not as rapid as with K6 since it seems to have had both considerable design problems and process problems which were gradually fixed on the way to where they are now. K7 has probably benefitted from K6 paving the way in design and process so there is "less to fix." The process is the same and Meyer said the design methodology is the same. Remember that MOScape tool that was talked about recently? That was perfected on K6.
