AMD RX 6800 XT

The AMD RX 7800 XT and AMD RX 6800 XT are both high-performance graphics cards from AMD, but they have some key differences. The RX 7800 XT is based on the newer RDNA 3 architecture, offering higher clock speeds, more stream processors, and improved ray tracing performance. It also features lower power consumption and less heat output. The RX 6800 XT, on the other hand, is based on the older RDNA 2 architecture, but still offers excellent performance and can often be found at a lower price. Overall, the RX 7800 XT is a more powerful and efficient graphics card, but the RX 6800 XT is a better value for the money.
