The NVIDIA GeForce RTX 3080 mobile outed with 16 GB of VRAM, a GA104 GPU and 6,144 CUDA cores
NVIDIA will equip the mobile version of the GeForce RTX 3080 with 16 GB of VRAM, according to multiple sources. The claim first appeared on Twitter with @OneRaichu, which was then seemingly later verified by a listing on South African retailer Pinnacle. The listing also states that the RTX 3080 mobile will be available with a Ryzen 9 5900HX, which has recently appeared on Geekbench.
As for the RTX 3080 mobile, @OneRaichu adds that the card will utilise GDDR6 VRAM on a 256-bit interface. Moreover, NVIDIA has apparently based the RTX 3080 mobile on its GA104 GPU, albeit one that contains 6,144 CUDA cores - 256 more than the RTX 3070 has. Essentially, the rumoured specifications of the RTX 3080 mobile read more like an upscaled RTX 3070 than a cutdown RTX 3080.
@OneRaichu expects the RTX 3080 mobile to perform comparably to the desktop RTX 3070, although it is unclear how they came to this assertion. NVIDIA is expected to begin releasing its RTX 30 mobile product stack from early next year, so it should not be too long before we learn more about the likes of the RTX 3080 mobile and RTX 3070 mobile.
The apparent confirmation of NVIDIA equipping the mobile version of the RTX 3080 with 16 GB of VRAM raises questions about its desktop counterpart, though. Currently, NVIDIA only sells a 10 GB edition, but there had been rumours about it releasing a 20 GB version. NVIDIA had allegedly cancelled this SKU, but a recent EEC registration by MSI suggests otherwise. It would be strange for NVIDIA to sell mobile GPU with 60% more VRAM than its desktop namesake, so maybe a 20 GB variant of the RTX 3080 is on the way after all.
