Shipped cache dies: AMD 3D V-Cache 64 MB on 41 mm^2 at 7 nm (1.56 MB/mm^2, Tom's Hardware, Hot Chips August 2021); Graphcore GC200 900 MB on 823 mm^2 with compute (1.09 MB/mm^2); Groq TSP 220 MB on 725 mm^2 at 14 nm (0.30 MB/mm^2); TSMC N5 HD SRAM macro 31.8 Mib/mm^2 after about 30% assist overhead (SemiAnalysis, December 2022). A 256 MiB mirror is about 165 mm^2 at 7 nm on the densest shipped cache-only die and about 130 mm^2 at N5/N3E, not 54 to 83 mm^2; cost per die 2 to 3x the earlier figure; the conclusion (affordable for a funded chip) stands. The analysis agent is redoing the table with both columns; the soundness agent carries the corrected density into the chip row. Latency citations behind the latency-bound rule, to be added: DRAM row cycle 40 to 48 ns across DDR4, GDDR5, HBM2 (Li, Reddy, Jacob, MEMSYS 2018); latency 1.3x in two decades against bandwidth 20x (Chang 2017); no shipped mining chip used HBM or stacked memory. + +## 21:25 proving v1 state for 0.3.11; PC 2 occupancy + +Proving v1 (acd4f36bc2c07a4e2): fork proving-v1 b177718e on a24ab01a (told to rebase onto commit 21d4c73c now), app proving-v1 79bc820 on a93199a.
