Nvidia GeForce RTX 4090 headed to laptops with an AD103 GPU
Nvidia GeForce RTX 4090 reviews have overwhelmingly concluded that the Ada Lovelace-based graphics card is incredibly power-hungry. Porting it to laptops would be nothing short of a nightmare, but Nvidia seems to be up to the task, at least that's what a new leak says. Twitter user REHAWK stumbled upon an internal document highlighting various Ada Lovelace laptop graphics cards, including the GeForce RTX 4090.
Prolific leaker Kopite7Kimi talked about the GeForce RTX 4090 mobile's existence months before its desktop counterpart was announced. It is codenamed GN21-X11 and uses an AD103 GPU with a TGP of 175 Watts. This will undoubtedly result in a significant performance delta between the desktop and laptop RTX 4090 variants, but Nvidia doesn't have much of a choice here due to thermal constraints. Thankfully, it will still benefit from all the architectural improvements bought forth by Ada Lovelace and take advantages of features like DLSS 3.
Interestingly enough, the Ada Lovelace mobile lineup skips the GeForce RTX 4080 entirely. The GeForce RTX 4090 is followed by the AD104-based GeForce RTX 4080 Ti (175 W TGP), GeForce RTX 4070 (AD106, 140 W TGP) and the GeForce RTX 4060 and RTX 4060 Ti, both with different AD106 variants. There is no word about when the Ada Lovelace mobile graphics cards will be launched, but if last year's release cycle is anything to go by, they should start showing up at around CES 2023.
