Intel 20K wafers per week ==> Intel yields suck This post is in response to Time Traveler who posted: [Intel starts] 20K wafers per week. After running the numbers, please share with us exposing any myths you come across Lets assume that for all of '98 Intel output is 50% at 0.35æ and 50% at 0.25æ and that 50% of 0.35æ output is Pentium MMX, the rest Pentium II. The die sizes are shown below, with the number of die sites on an 8" (31,400 mm^2) wafer shown in {} assuming 10% wasted space. Deschutes 0.25 Pentium II(50% of output): 131 mm^2 {215 die} Klamath 0.35 Pentium II (25% of output): 203 mm^2 {139 die} 0.35 MMX (25% of output): 140 mm^2 {202 die} To get the product mix above, they would need 4500 wafers/week for MMX production, 6500 wafers/week for Klamath production and 9,000 wafer/week for the new 0.25æ Pentium II's. If Intel had 100% yields, they should be able to produce the following quantities of CPU's in 1998: 900052215=101 million 233-300 MHz 0.35æ Pentium II's 650052139=47 million 333-450 MHz 0.25æ Pentium II's (& Celeron) 450052202=47 million 166-233 MHz 0.35æ MMX CPU's Intel will do well to sell 90 million CPU's in 1998. Therefore their blended yield is below 50% or they are operating way below capacity. Actually, if Intel stopped making the obsolete 0.35æ parts as soon as AMD, they should be able to run with only two fabs, each running 5,000 wafers per week. Petz
