Goldshell AL Card modes and BYTE host boundary

The AL Card is a Blake3 compute card for Alephium. It cannot operate separately and requires the Goldshell BYTE main unit. Its performance and power figures describe the card mode, not total facility draw for a complete BYTE system.

Exact card modes

Goldshell publishes high-power mode at 120 GH/s ±5%, 65 W ±5%, and 0.54 J/GH. Default mode is 90 GH/s ±5%, 45 W ±5%, and 0.50 J/GH. These two modes remain separate; neither is presented as a standalone miner operand.

Physical specification

The card measures 123 × 21 × 88 mm and weighs 0.325 kg. The package is 184 × 156 × 56 mm and 0.527 kg. The listed fan specification is 5,500 rpm, which is not a numeric acoustic measurement. The former Not independently specified value and Not independently specified weight are removed.

Host and power boundary

High-power mode requires Goldshell’s 140 W wall charger. Default mode may use a charger that supports 20 V / 5 A output. The card’s 65 W or 45 W value is not the wall draw of the BYTE host plus charger and cannot support standalone electricity, BTU, or profitability calculations.

Firmware and handling

Goldshell says future cards can be used by replacing cards and updating BYTE firmware, but publishes no exact AL Card artifact/version in the cited material. Verify BYTE and card revision compatibility before updating. Goldshell recommends shutting BYTE down with the main button or app before removing a card; hot swapping is not recommended.

No standalone acoustic, residential, solo-mining, heat-output, or economic profile is published because this is a required-host component.
