As for the Radeon RX 6600, it will feature 28 CUs with 1792 streaming processors and score 7805 points in 3DMark Time Spy (17% less than the RX 6600 XT). The Ethereum mining performance is about 10% inferior to that of the RX 6600 XT, resulting in a hash rate of 27MH/s.

The release date of these cards hasn't been confirmed, but they are expected to release in Q2 2021.

KitGuru says: Considering the expected mining performance, these GPUs appear less likely to be targeted by crypto farms, which will hopefully lead to more stock and availability for gamers.
