The forecast for the Q1 revenue of Nvidia is excellent owing to the high demand for its gaming chips which remains in tight supply. CFO Colette Kress said, cryptocurrency mining has contributed approx. between $100 mn and $300 mn in sales in Q4. Nvidia also plans to start shipping software with gaming chips that slow down the ability to mine some currencies and later release a mining-specific chip, to discourage miners from using gaming chips.
