A Korean forum user has leaked what appears to be a canceled AMD flagship GPU cooler—featuring a massive triple-slot, triple-fan design with three 8-pin power connectors. This suggests AMD developed a high-end prototype (potentially an RX 7950 XTX) targeting over 375W power draw, far beyond the 355W RX 7900 XTX.

The cooler’s extreme design—lacking PCIe brackets or PCB—indicates advanced thermal testing for an unreleased Navi 31 variant.
Key Evidence of a Supercharged Navi 31
- Triple 8-pin connectors: Supports 375W+ (vs. RX 7900 XTX’s dual 8-pin + PCIe slot)
- Industrial-grade heatsink: Thicker than any reference RDNA 3 cooler
- No retail markings: Serial codes don’t match known AMD models
- Historical precedent: AMD released special editions like RX 6900 XT Liquid Edition

This aligns with rumors of AMD exploring a binned “Navi 31 XTXH” chip for higher clocks.
Why AMD Likely Canceled the Project
- Market timing: NVIDIA’s RTX 4090 dominated the premium segment
- Thermal challenges: Cooling 375W+ efficiently would require expensive vapor chambers
- Product overlap: RX 7900 XTX already competed at $999
- RDNA 4 focus: Resources shifted to next-gen architecture
Industry insiders note similar prototypes often test thermal limits but never launch,

The Bigger Picture
This leak confirms AMD did develop enthusiast-tier RDNA 3 hardware but hesitated to challenge NVIDIA’s absolute performance crown. The focus now shifts to RDNA 4—though power-hungry prototypes remind us AMD hasn’t abandoned high-end ambitions.
