A Newegg listing of the AMD Ryzen 9 5980HX-powered Asus ROG Zephyrus Duo SE was spotted online. Its specs include a GeForce RTX 3060 graphics card, 16GB of RAM and a 1TB NVMe SSD. The Cezanne-based processor was also spotted on the Userbenchmark database.

A 4K/3080/5980HX model has been on Scan (sorry, no linking due to low post count) since around May. I have no knowledge about its legitimacy, as I was not quite willing to pay a 1300 USD premium over the US 5900HX equivalent model (3700 USD for 5900HX and 3600 GBP for 5980HX), and there are some suspicious inconsistencies in the tech specs.
