ASUS Launches NVIDIA GeForce RTX 4090 eGPU for ROG Flow Laptops with $1,999.99 Price Tag

Is there anyone out there who would pay $1,999.99 strictly for the laptop version of NVIDIA’s GeForce RTX 4090 GPU? That seems to be the question that ASUS ROG is asking with the XG Mobile (2023), a new version of the company’s external GPU and hub accessory that not only features NVIDIA’s flagship Ada GPU for mobile gamers, but also a $2K price tag, making it even more expensive than many of the GeForce RTX 4090 desktop graphics cards that can be found on today’s market. What’s even better is that this eGPU is exclusive to ASUS’ ROG Flow laptop family (e.g., the ROG Flow X13)—the hardware is combined via a proprietary PCIe (3.0 x8) connector that is said to offer up to 63 Gb/s of theoretical bandwidth, higher than Thunderbolt 4 (40 Gb/s).
