Initial T512-N4 energy and thermal confirmation
T512-N4 preserves its speed gain without worsening energy per hash or thermal stability.
Diagnostic work, exact algebra and local capabilities are not treated as end-to-end mining advantage.
What was tested?
T512-N4 preserves its speed gain without worsening energy per hash or thermal stability.
Why the test is meaningful
A throughput win can be operationally inferior if it consumes more energy; measurement order and heat history must be balanced.
Eratio=(J/hash)_N4/(J/hash)_N32noninferior iff header ratios≤1.002 and CI bound passesorder∈{ABBA,BAAB}How it was tested
Measure six unseen headers, 72 processes and NVML at 100 Hz, alternating ABBA and BAAB by header.
What happened
Speed persisted at 1.002946× kernel, but energy noninferiority did not pass: aggregate ratio 0.982385, only 3/6 headers within gate and 95% interval 0.948442–1.017544. ABBA and BAAB groups diverged strongly.
Exactness and statistical controls
The order split is reported as confounding rather than averaged away. Exact B32 and thermal gates passed.
What the result means
Speed remains credible; energy is inconclusive because position/heat dominates the small effect. A within-header paired design is required.
Limitations
- Order is confounded with header.
- Energy verdict is neither confirmed nor rejected.
- NVML is device-level measurement.
Evidence trail
Do not reuse the naive aggregate; pair both order sequences within every header as in the registered successor.
