AMD Slot A is a leap over the Slot 1 in performance. Timing skew means Slot 1 100 MHz bus can only be extended to about 133 MHz and I doubt Slot 1 can support RAMBUS technology. Slot A will start at 200 MHz, and support cheap dual-data rate SDRAM, as well as direct RAMBUS. John, I still haven't heard a good argument why anyone would want to attach RDRAM to a CPU. The latencies are long and it is not a normal CPU function to burst anything longer than a cache line in or out of the processor. RDRAM is a great technology for graphics adapters, which do burst very large chunks of data. 3DNow implementation in K7 will be a superset which extends 3DNow SIMD performance to double precision. Tune in next Tuesday. Sounds very interesting.... Scumbria

Re: "AMD Slot A is a leap over the Slot 1 in performance. Timing skew means Slot 1 100 MHz bus can only be extended to about 133 MHz and I doubt Slot 1 can support RAMBUS technology. " I don't know where you got this John but it's not true. Maybe not Slot1 in it's current form but the GTL+ signals will scale well above 200mhz data rate. In theory data could be double pumped and thus the 133mhz clock would effectively make the data rate 266mhz. In addition, what would stop Intel from doubleing the databus and achieving the same thing SlotA does? I really don't see anything that SlotA adds but higher cost with all those additional pins. EP

Petz - Re: Slot A will start at 200 MHz, and support cheap dual-data rate SDRAM, as well as direct RAMBUS." Remember the word - CAMINO. You may hear that word in connection with Rambus, DDR and SLot 1 Intel cards. Do you think Intel hasn't heard of RAMBUS before? Get a clue. Re: "AMD Slot A is a leap over the Slot 1 in performance." That's funny. If it is such a leap, why don't you provide some SYSTEM BENCHMARKS to BACKUP your claims? Or do you really mean it is a "LEAP OF FAITH "? Paul
