An engineering sample of what appears to be an AMD RX 7900 XTX graphics card has surfaced, featuring a distinctive red PCB and lacking a backplate. This prototype, purchased on the secondhand market, includes specialized connectors for diagnostic data collection and signal quality testing, as well as dip switches for testing PCIe compatibility. While recognized as a 7900 XTX in software, its hardware specifications, including 16GB of GDDR6 VRAM, ROP count, TMU count, and bus width, align more closely with the RX 7900 GRE, suggesting it may be a prototype for a cut-down version of the Navi 31 silicon.
