Paul, re: "$10, cost of silicon per chip, goes up to $14"

(31400 mm^2 per wafer / 81mm^2) * 90% useful area * 60% typical AMD yield = 209 K6-2 chips per wafer

(31400 mm^2 per wafer / 117mm^2) * 90% useful area * 60% typical AMD yield = 145 K6-3 chips per wafer

Wafer cost, including cost of wafer + direct manufacturing costs (chemicals, labor, etc) has been estimated by YOU to be $2,500, but I've seen figures as low as $2,000.

Cost per K6-2 chip = $11.96
Cost per K6-3 chip = $17.24

Additional cost for K6-3 = $5.28

Of course, even these K6-3 wafers have more chips on them than Intel's Celeron wafers.
