The Radeon RX 6800 is the cheapest graphics card equipped with a Navi 21 graphics chip. That is naturally slower in this card than in the RX 6800 XT and RX 6900 XT, but the RX 6800 clearly offers the most attractive price/performance ratio of the three. And the power draw is also not bad, the efficiency is remarkably very decent here, despite the large, partially deactivated core. However, some flaws can be found on the AMD reference card.
