Ethereum is no longer GPU-mined and operates as a proof-of-stake network.

"It is a different thing today, right? It's not GPU-based, it's more proof-of-stake, all that" (said at 0:58:15)

Ethereum transitioned its consensus mechanism from Proof of Work (which relied on GPU-based mining) to Proof of Stake during an upgrade known as 'The Merge' in September 2022. This shift eliminated the requirement for energy-intensive GPU mining and moved the network to validator staking for block validation.

  "To deliver effective scaling solutions, Ethereum achieved a significant protocol improvement, including a change in the consensus mechanism towards Proof of Stake. This improvement greatly reduced the hardware requirements to run a node, leading to significant sustainability benefits with a lower network energy consumption." (abstract, passage verified)
