We reported in May, via MoreMate Law, that Nvidia could outfit the RTX 5080 and RTX 5070 mobile versions with more memory than their RTX 40 counterparts. The RTX 5080 would have been equipped with 16GB of VRAM, while the RTX 5070 would as well. I made use of 12 GB.
The MLID has now been doubled by an RTX 5080 laptop VRAM leak and has revealed the potential CUDA number of the GB203 GPU expected to power the card.
RTX 5080 laptop specifications
The RTX 5080 laptop is said to be based on the GB203 GPU, a chip that also powers the RTX 5090 laptop and RTX 5080 desktop. Desktop RTX 5080 office. Of course, the GB203 of the RTX 5080 laptop is likely to be a downsized version and features fewer CUDA cores than the desktop RTX 5080, and the MLID reveals a possible configuration of the RTX 5080 laptop with 8,192 CUDA cores and 16GB of GDDR7 memory. This is a significant reduction in the number of cores available in the GB203.
However, even pulling back on the specs, MLID has some ambitious estimates for the RTX 5080's performance.
RTX 5080 laptop performance
MLID estimates that with 16GB of VRAM and 28Gbps of speed and the bandwidth that comes with it, an RTX 5080 can be 45-65% faster than a laptop. RTX 4080. This feature will allow the mobile GPU to achieve the same performance as the RTX 4070 Ti Super and up to the RTX 4080.(Buy the RTX 4070 Ti Super from Amazon).
However, these performance numbers are just the product of the leaker's “cheap calculations”. So this is an educated guess and not a leak.
Suffice it to say that the RTX 5080 laptop is shaping up to be a 1440p/4K gaming beast with a huge improvement over the RTX 4080 laptop's GPU.
