Scumbria, Re: The Alpha 21164 already runs at 700 Mhz in an old 0.35u process. Samsung is promising 1GHz by the end of the year. Does that mean 21264 is a step backward as it seems to have some problem going above 600Mhz ? Also, will they still make 21164 given that 21264 is out. Based on indication from Compaq, it seems that they are going to sell 21264 based system only. Gary

Re: "The Alpha 21164 already runs at 700 Mhz in an old 0.35u process. Samsung is promising 1GHz by the end of the year." Perhaps but the Xeon out performs it in integer operations. Re: "What K7 has that Intel and IBM don't, is a 3-cycle L1 cache lookup. P6, PPC, K6, M1 all use a 2-cycle cache lookup. There is not enough time to do address calculation, address translation, cache lookup, and cache array access in 2 cycles at 600+ Mhz." What Intel has is production silicon and positive margins. AMD has foils. Re: "Alpha, Willamette, M3, K7 all are using >2 clocks L1 lookups. K7 and Alpha are the first to get there however." K7 doesn't have anything. There is no production silicon. EP

Scumbria, Re: There is not enough time to do address calculation, address translation, cache lookup, and cache array access in 2 cycles at 600+ Mhz Forgive my ignorance but hasn't PIII hit the 550 point and is it possible to squeeze a bit more(may be jack up the voltage) to go beyond 600Mhz ? Gary
