New Radeon RX 7900 series GPUs from AMD with RDNA 3 architecture have been introduced. According to claims, the new Radeon RX 7900 XTX and 7900 XT GPUs outperform previous generation hardware by 54%. It appears that AMD CEO Dr Lisa Su is making fun of Nvidia's GeForce RTX 4090 when she claims that the firm is focused on providing great performance with optimal battery utilisation.
