Here's what is possibly the very first picture of an AMD Radeon RX 7900 XTX RDNA3 graphics card. AMD engineering samples and prototypes tend to use red color PCBs, which is what this card is. It reveals what could be the final design of the reference cooling solution for the card, and it seems to match the teasers the company put out in its Ryzen 7000-series launch event.

The RX 7900 XTX cooling solution design builds on that of its predecessor. The card itself has 3 slots thick, but slightly longer than the RX 6900 XT. The aluminium fin-stack heatsink is bulkier than the one on the RX 6900 XT cooler, and appears to be bursting out of the vents. It stretches out to the edges of the cooler shroud. The bulge toward the tail-end could be housing the tips of the heat-pipes. The prototype card has two 8-pin PCIe power inputs. There's no backplate, because the PCB has several headers in place for diagnostics and developmental use by AIBs and OEMs.

AMD's next-generation Radeon RX 7000-series graphics cards based on the RDNA3 graphics architecture, are expected to launch in early-December 2022, according to greymon55, a reliable source with AMD leaks. The cards will be unveiled at a media event to be held on November 3, 2022, with market availability following a month after (between 1st to 5th December). The company is expected to take a top-down product-stack release cycle similar to that of NVIDIA, with the release of two of its top SKUs, the Radeon RX 7900 XTX and the RX 7900 XT. Both these cards are based on the 5 nm Navi 31 MCM GPU. This will be AMD's first client-graphics MCM GPU with more than one logic die. The company has a decade of experience with MCMs, but past generations have been one logic die surrounded with on-package HBM. Navi 31 has on-package logic chiplets, but discrete GDDR6 memory, like most other GPUs in the market today. It's rumored that the company is targeting a 100% performance uplift over the previous-generation, which means team-red is on the prowl to compete with NVIDIA's fastest SKUs, including the RTX 4090 and upcoming RTX 4080.
