NVIDIA's current generation GeForce RTX 4090 and GeForce RTX 4080 laptop GPUs are housed inside desktop GPUs, at least in China.

According to a new article in VideoCardz, mobile GPUs are being made with lower operating margins by using cheaper mobile GPUs, lower-budget cooling designs, simpler PCBs, with a power limit of 175W due to their mobile nature. Apparently there is a Chinese company that specializes in selling it as a desktop GPU. GPU.
This doesn't mean it's all smooth sailing. There are also warranties that gamers have to worry about and possible issues with driver support. VideoCardz reports that it has received emails from readers who are having “difficulties” using these cards. Consumers of these mobile-to-desktop GPUs must use modified drivers or drivers provided by sellers who have no idea where they come from.
NVIDIA's flagship GeForce RTX 4090 laptop GPU features an AD103 GPU with 9728 CUDA cores, a 40% reduction in CUDA core count compared to desktop GeForce RTX 4090 graphics cards. Another big difference between the RTX 4090 laptop GPU and the RTX 4090 desktop GPU is that the mobile version has 16 GB of GDDR6 memory, 8 GB less than the desktop GPU, while the desktop RTX 4090 has faster GDDR6X memory. It is also equipped with .
Next, the GeForce RTX 4080 laptop GPU has 7424 CUDA cores, which is a 24% reduction in CUDA core count compared to the desktop RTX 4080. In terms of memory, the RTX 4080 laptop GPU comes with 12GB of GDDR6 memory, which is 4GB less than its predecessor. Desktop RTX 4080 with 16 GB of fast GDDR6X memory.
Chinese sellers sell the GeForce RTX 4080M with performance that falls between the desktop RTX 4070 and RTX 4070 Ti graphics cards, but with a power limit of 175W, the RTX 4070 with a default power of 285W It will be interesting to see how it fares against Ti. limit.
The new GeForce RTX 4080M (desktop GPU) is priced between 3,000 RMB and 4,000 RMB (about 420-560 USD). On the other hand, the new GeForce RTX 4090M (desktop GPU) has a much higher price tag of 13,800 RMB (approximately over $1,900).

This makes it an RTX 4090M. more expensive It's better than the official RTX 4090 desktop GPU, but due to US sanctions, RTX 4090 graphics cards are banned in China… so I guess these sellers can do whatever they want.
The new GeForce RTX 4090M and GeForce RTX 4080M are very new in China, arriving this month, but there's no mention (yet) of the RTX 4070M or RTX 4060M models.
In any case, please be careful: These are nowhere near the performance of the RTX 4090 and RTX 4080 due to their gimps (CUDA core count, VRAM count, power cap limitations), so if you live in China and consider one of these new RTX 4090M Please be careful if you do. or RTX 4080M desktop graphics card.
