While not yet a standard shelf item in every store, engineering samples labeled as the RX 9080 XT have surfaced in benchmark databases. This card is essentially a “supercharged” version of the 9070 XT, utilizing a more refined manufacturing node and massive clock speed boosts.
Memory Architecture: The biggest leap is the move to GDDR7 memory. Most leaks point to a 16GB or 32GB configuration on a 256-bit bus, offering bandwidth that rivals or beats the old 7900 XTX.
Insane Clock Speeds: Engineering samples have been spotted running at 3.7 GHz to 4.0 GHz—the highest clock speeds ever seen on a consumer GPU.
Performance Target: It is designed to be 25–30% faster than the 9070 XT in 4K resolution, effectively placing it between the RTX 5080 and the RTX 4090.
Power Consumption: To hit those speeds, it is a power-hungry card, with a TBP (Total Board Power) reaching up to 450W.
