AMD has announced its next generation of graphics cards, the RX 7900 XTX and RX 7900 XT, the first graphics cards powered by its new architecture RDNA 3, which uses a chiplet design similar to the Ryzen processors.
AMD RDNA3 architecture based on the 5nm node is the first chiplet design for consumer Radeon GPUs. The GPU features a 5nm compute engine and six memory chiplets built with a 6nm node.
The company promises RDNA 3 up to 54% performance per watt increase over RDNA 2, which used a more traditional GPU design. AMD says it can produce up to 61 TFLOPs, compared to RDNA 2's 23 TFLOPs.
AMD Radeon RX 7900 XTX
AMD confirms that its new RX 7900 XTX will be up to 1.7 times faster than the RX 6950XT at 4K resolution.
The Radeon 7900 XTX is the first Radeon card to support the DisplayPort 2.1 display interface, offering support for up to 8K 165Hz or 4K at 480Hz.
At 4K, AMD promises 62 fps in Cyberpunk 2077 with its ray-traced 7900 XTX card and AMD FidelityFX Super Resolution (FSR) enabled.
AMD Radeon RX 7900 XT
The 7900 XT is based on a downsized engine with 10752 stream processors and 20GB of GDDR6 memory with estimated total power consumption of 300 watts.
