Now there's some more information from NVIDIA's Bryan Del Rizzo. Via a tweet, he reveals that the anti-cryptocurrency mining protection is a "secure handshake" between the driver, the RTX 3060 silicon, and the BIOS. When the NVIDIA algorithm detects Ethereum mining, it artificially throttles performance to roughly cut the mining hash rate in half. This makes mining on these cards a lot less profitable, or even unprofitable.
Hi Ryan. It's not just a driver thing. There is a secure handshake between the driver, the RTX 3060 silicon, and the BIOS (firmware) that prevents removal of the hash rate limiter.— Bryan Del Rizzo (@bdelrizzo) February 19, 2021
VideoCardz writes there are rumors that NVIDIA will relaunch existing Ampere SKUs under a new device ID. Allegedly, the company will expand its anti-mining algorithm to cards like the GeForce RTX3090/3080/3070/3060Ti. This hasn't been officially confirmed yet.
Two questions remain.
- Is the anti-mining algorithm really as secure as NVIDIA claims? If the answer is yet, the company may have finally found a way to preserve its GeForce GPUs for gamers. Miners will be forced to buy NVIDIA's new Cryptocurrency Mining Processors (CMPs). Of course, this will only make a difference if NVIDIA prioritizes GeForce GPU production.
- Will AMD follow NVIDIA's lead? Or will miners now flock to AMD?
