  "textContent": " R200=Rubin 1250=MI455X\nIn the case of Rubin, it appears that adaptive compression(achieved 50) has replaced 2:4 structured sparsity.\nI am uncertain whether the value is 25 or 35. On the other hand, I've put together a table where the MI455X is listed with the same value.\n (https://chipsandcheese.com/p/amds-cdna-4-architecture-announcement)\nSemiAnalysis stated that FP4 is 32,768, but it seems highly likely that this is a dense value. The matrix value seems to be based on sparsity?\n\nSo, to conclude, how accurate would you say the table above is? (25 or 35 etc)",
