> You are citing wafer sizes. Fabs are measured in mask sizes, the density, not the overall radius. The fact that these are 150 and 200 mm fabs tells us that these are using machinery from the 80s or early 90s, respectively. So these fabs are probably using several-hundred nm processes. > have much better fabs ... So the Bosch Asics will run at roughly C64 speeds. Good enough for consumer cars. Maybe look at Bosch's semiconductor portfolio? They're not in the business of making commodity parts like processors or MCUs which benefit from being on small nodes. They do specialty mixed-signal, power ASICs and MEMS devices. Smaller is not always better. This is easy to overlook when "silicon" is only though of as CPUs and GPUs.
