Priced at $999 and $899, respectively, the GPUs will go on sale in December. AMD promises that the graphics cards' new architecture will bring great improvements to 4K performance.
On November 3, during the together we advance_gaming event, AMD revealed two new GPUs, the RX 7900 XTX and RX 7900 XT, powered by the company's new RDNA 3 architecture.
AMD emphasized that RDNA 3 is the world's first product architecture to use chiplets. The chiplets include a 5nm GPU compute die and a 6nm memory cache die. The graphics processor has 58 billion transistors and can manage up to 24GB of GDDR6 RAM, and its performance reaches up to 61 teraflops. The chip will be used in the RX 7900 XTX and Radeon RX 7900 XT video cards which were presented at the live stream.
Both graphics cards will go on sale on December 13, 2022, and will have DisplayPort 2.1 support which means that the graphics cards will provide higher refresh rate support. According to AMD, thanks to graphics accelerators, some games will be able to run at 1440p and even 4K at triple-digit frame rates.
The RX 7900 XTX, the company’s new flagship GPU, is aimed at 4K gaming with AMD claiming that it should be 1.7 times faster than its existing RX 6950 XT card at that resolution. At the same time, the GPU's power draw is said to be only 355 watts (compared to 450 watts for the flagship NVIDIA RTX 4090). The graphics card will feature 96 compute units clocked at 2.3Ghz and have 24GB of GDDR6 memory running at 384 bits.
The RX 7900 XT is a little less powerful – it has 84 compute units with a base clock speed of 2Ghz and a little slower 320-bit memory bus. The flagship RX 7900 XTX will be priced at $999, while the RX 7900 XT will sell for $899.
