Kap, The original P7 was a design inspired by Alpha's simplicity and high clock rates. In the fall of 1994 Albert Yu conducted a project review and declared that P7 design -- get this -- was not aggressive enough and did not meet the goal of 40% performance increase at the same clock speed. Of course the design was great, but the goal was dead wrong. The P7 project was killed and Albert Yu signed a deal with HP and started Merced. Interesting tidbit. Gee, 40% performance increase at the same clock speed was not good enough? I guess he (Albert Yu) can re-evaluate his conclusion when P4 is released with no gain, and possibly a loss in performance at the same clock speed than the chip it is replacing. The thinking was that the trace cache faults would be rare, so the chip would be running twice as fast as P6 without changes to the decode logic. I guess they may have underestimated the code bloat, and the need of multitask OS/aplications to switch context. We will see sooner or later how it really performs. Joe
