What share of all chips are high-end data center AI chips?

In 2021, the semiconductor industry reportedly produced about 1.15 trillion units (Kharpal, 2022). As calculated above, the production of high-end AI chips in 2022 was likely less than 3 million. This suggests that high-end AI chips only accounted for less than 1:4,000 (0.00026%) of all chips produced.

I’m sorry, HOW MANY UNITS?
