Paired ABBA/BAAB energy audit for T512-N4

Balancing both order sequences within every header confirms T512-N4 energy/thermal noninferiority.

Claim statusNO END-TO-END MINING ADVANTAGE DEMONSTRATED

Diagnostic work, exact algebra and local capabilities are not treated as end-to-end mining advantage.

01 / Question & hypothesis

What was tested?

Balancing both order sequences within every header confirms T512-N4 energy/thermal noninferiority.

02 / Scientific basis

Why the test is meaningful

Within-header pairing removes header/order confounding and equalizes internal and external measurement positions.

03 / Method

How it was tested

Run four unseen headers, three paired ABBA+BAAB blocks per header, 96 processes and NVML at 100 Hz.

04 / Observed result

What happened

Kernel speedup1.002816×
Energy / hash ratio0.980209
Headers favorable4 / 4

N4 improved kernel throughput 1.002816× and process throughput 1.002642×. Energy/hash ratio was 0.980209, favorable on 4/4 headers with paired 95% interval 0.961683–0.999091. Mean power fell from 233.32 W to 229.52 W; maximum temperature was 66°C.

05 / Validation

Exactness and statistical controls

Both binaries produced exact B32 results and every preregistered throughput, energy and thermal gate passed.

06 / Interpretation

What the result means

T512-N4 becomes the confirmed local RTX 5080 default: slightly faster and lower energy per hash under the balanced design.

Limitations

  • The conclusion is RTX-5080-local.
  • It does not alter hash probability.
  • It is not extrapolated to ASICs.
07 / Reproduction

Evidence trail

Use the sealed binaries/checksum, equal positions within each header, direct NVML sampling and paired confidence interval.
