 ### Bitrate
 
 
+## Encoder Precision Parity
+
+Difference from FP32 reconstruction on a disjoint real-data holdout; lower is better.

+| Encoder | P90 PRD | Worst PRD | Status |
+|---|---:|---:|---|
+| FP16 | 0.00% | 8.56% | recommended |
+| INT16X8 | 5.15% | 17.46% | recommended |
+| INT8 | 10.77% | 42.82% | higher error; use knowingly |
