By the time these systems become fully operational, TSMC is expected to have advanced to its A10 node, representing several technological generations beyond its current capabilities. This timeline aligns with TSMC's broader roadmap for advancing chip manufacturing processes.
I can only imagine what the costs would be for A10 fabrication. I remember doing some back of the napkin calculation based on public info and the latest TSMC node represented about ~20% of the cost of a Zen 5 CPU. I wouldn't be surprised if this increases to 30-40% even with a significant in base prices of leading CPUs.
