The Radeon RX 7990 XTX is a graphics card by AMD, that was never released. Built on the 5 nm process, and based on the Navi 31 graphics processor, in its Navi 31 XTX+ variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 7990 XTX. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The Navi 31 graphics processor is a large chip with a die area of 529 mm² and 57,700 million transistors. It features 6144 shading units, 384 texture mapping units, and 192 ROPs. The card also has 96 raytracing acceleration cores. AMD has paired 24 GB GDDR6 memory with the Radeon RX 7990 XTX, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 2500 MHz, which can be boosted up to 3599 MHz, memory is running at 3000 MHz (24 Gbps effective).
Being a triple-slot card, the AMD Radeon RX 7990 XTX draws power from 3x 8-pin power connectors, with power draw rated at 405 W maximum. Display outputs include: 1x HDMI 2.1a, 2x DisplayPort 2.1, 1x USB Type-C. Radeon RX 7990 XTX is connected to the rest of the system using a PCI-Express 4.0 x16 interface. The card's dimensions are 287 mm x 135 mm x 50 mm, and it features a triple-slot cooling solution.
