Not sure if these numbers can believed, but apparently a 300mm wafer at the 5nm node costs about $17000 for TSMC to process https://www.tomshardware.com/news/tsmcs-wafer-prices-reveale... Since the M1 is 120 mm2 and a 300mm wafer is about 70695 mm2, you could theoretically fit 589 M1 chips on a wafer. Subtract the chips lost at the edge and other flaws, you might be able to get 500 M1 off a wafer? (I know nothing abo…
The M1 Max is slightly off-square and 432mm^2. 19.1 x 22.6 seems like a decent fit. TSMC has stated that N7 defect density was 0.09 a year ago or so. They have also since stated that N5 defect density was lower than N7. Let's plug that in here https://caly-technologies.com/die-yield-calculator/ If we go with a defect density of 0.07, that's 94 good dies and 32 harvest dies. At 0.08, it's 90 and 36 respectively. If we…
And I agree - Apple making their own chips is sure looking good for their bottom line vs buying from Intel
