A while back, we covered a leak of "
Panther Lake," Intel's next-generation Core Ultra 300 series CPUs. The leaked package thankfully included information about die sizes, which we can input into the calculator to find out the yield, assuming Intel is manufacturing Panther Lake compute tiles on the 18A node, using the aforementioned d0 of 0.4. The die number four with a CPU and NPU on it, measuring 8.004x14.288 mm, a 114.304 mm² silicon die, gives a yield of 64.4% on the default Murphy's model. Moore's model is the most pessimistic, with only about 50% of usable dies. The die number five of Panther Lake, housing the Xe3 GPU, is even smaller and measures only 53.6 mm², yielding an impressive 81% of usable dies. Even with the most pessimistic assumptions, the yield curve drops to 60%.
