Ethereum Switches to Proof of Stake, GPU Mining is Dead

NVIDIA Ada and AMD RDNA3 will not sell to Ethereum miners. In a dramatic move, the creators of Ethereum have switched over the popular crypto-currency’s algorithm from proof-of-work, to proof-of-stake, which means miners will no longer spend GPU resources in competing to find the same blocks. This effectively ends GPU-accelerated mining as Ethereum mining was the number-1 consumer of high-end GPUs through 2021. The switch-over happened as the total terminal difficulty surpassed 58,750,000,000T, with the last block having been found. With this move, global electricity consumption is expected to reduce by 0.2% (that’s enough to power the world’s top 5 cities).

The impact of this move on GPU sales to crypto-currency miners is expected to be profound. GPUs are no longer an economical way to mine Bitcoin, ASICs are; and Ethereum mining constituted the bulk of activity from GPU-accelerated mining farms. This doesn’t mean there aren’t other crypto-currencies that rely on GPU-accelerated proof-of-work blockchain compute; but Ethereum had the highest market-cap among such currencies. Gamers have reason to rejoice, as NVIDIA and AMD now have to sell high-end GPUs squarely on merits of gaming performance, power-draw, and graphics card pricing.
