Josh watched the 9070 XT at 90% usage with its fans barely turning and the app could not say what it drew: the
draw, temperature and MH per watt line came from nvidia-smi only, and the earlier per-watt figure used the board
rating. proto-opencl/gpu-telemetry.c prints one line per AMD card per sample (bus from SetupAPI by the display
device's name, kind, name, watts, temp_c, fan_rpm, fan_pct, mclk_mhz, gclk_mhz, util_pct, source), built by
build-windows.sh against vendor/adlx (the SDK clone), shipped by make-payload.sh and push-inputs.sh. The engine
runs it with -l 5 beside nvidia-smi (Source::AmdTelemetry, tick_amd_telemetry), parse_amd_telemetry fills
power_w, temp_gpu, fan_pct, fan_rpm, mclk_mhz, util_pct and telemetry_at on the AMD card matched by kind and
ordinal, so eff_mhw and the dashboard's existing line show it; app.js shows fan and memory clock when present.
Tests: three on the parser with lines captured on PC 1 and the Mac fixture; the sysfs path ran on a fixture tree.
Measured over 20:27:45 to 20:29:41 UTC with both cards mining (docs/bench-log.md, under the 9070 XT ceiling table):
9070 XT 198.9 W (193 to 212), 64 C, 657 rpm, 2,505 MHz memory, 3,290 MHz shader, 100% busy, 17.73 MH/s =
0.089 MH/W; RTX 5090 307.6 W, 69 C, 44% fan, 122.30 MH/s = 0.398 MH/W.
