Tench, Maybe I wasn't sure what your question was as you had Foster and Wildfire in the same paragraph. This question is much more straight forward: "With all due respect, Rob, I don't think you answered my question. What happens if 4-way Foster proves to be more powerful than a 4-way Alpha server in 2001?" I see a window here where that happens, but that is happening today too (4 processor Xeon/whatever is doing better versus Alpha on tpcs). However, in a 2001 timeframe EV7 ships (maybe/hopefully) with on-chip L2, on-chip network switch (CPU to CPU), on-chip memory switch at a projected 1.5 GHz. Pretty even race if Foster has all those features too. In other words, Alpha gains more than parity and decreased cost by leaving out *complicated* chipsets (we beat that horse a while back) and maybe even L3 (jury is still out on that, a periodic fishing question to comp.arch "What about L3 for 21364 aka EV7"? Since it comes up so often, one wonders if L3 is even necessary with on-chip memory switch and RDRAM, seems doable to negate L3.) But think about that for a while and dredge up the IA64 whitepaper:digital.com If you check out page 30, you'll note Linley points out McKinley doesn't even have on-chip network nor on-chip memory switches... So that raises interesting issues... among them that Foster will not only outperform Merced but also give McKinley a run for its money (with on-chip trickery). If Foster lacks these features, won't do well against EV7 and a bonus with EV7 should allow for very good server prices by leaving out *complicated* chip-sets and L3 (conjecture, but reasonable). Since McKinley is feature poor compared to EV7, how do you suppose it will do performance-wise versus EV7? Rob
