Worked example: the result, and the point where NVFP4 would flip

Select FP8: 89.4% at 1,200 tokens/s and 45 ms. NVFP4 fails quality; 8,900 correct items is its flip threshold.derived

Value kindderived — Derived values are guide calculations; their result is only as fixed as the stated inputs, scope, and method.
ScopeHypothetical evaluation counts, throughput and latency from Chapter 7.10's worked example; not a measured model result. The arithmetic is worked in the chapter and kept in this claim's derivation field.
As of2026-09
SourceGuide derivation from a worked example with hypothetical inputs, Chapter 7.10, 2026-09-08; no supplier quote or test measurement.
DerivationBaseline accuracy = 9,000/10,000 = 90.0%. FP8 = 89.4%, a 0.6-percentage-point drop; NVFP4 = 88.8%, a 1.2-point drop. Both synthetic runs clear throughput and latency, but only FP8 clears 89.0%. NVFP4 must reach at least 8,900 correct items on this fixed test, an increase of 20, while retaining the other gates. This threshold concerns percentage points, not relative percent accuracy.
