AMD Radeon RX 6800
The AMD RX 6800 release price (MSRP) in the US was $579 at launch. Currently the RX 6800 retail price is $399 on Amazon. AMD RX 6800 used price is around $366.
Maybe, when purchased new, the Radeon RX 6800 offers a fairly satisfactory performance with its $399 price tag. However, it doesn't quite match up to the similarly priced Radeon RX 7700 XT, what outpeforms Radeon RX 6800 by 8.0% in 3DMark benchmark.
In the used market, the Radeon RX 6800 fails to justify its value for money. It lags behind the GeForce RTX 3080 what outpeforms it by a lead of 10.5% in 3DMark benchmark.
