According to Videocardz, the RTX 3080 Ti Mobile will be the first of its kind to use 16Gbps GDDR6 memory, as well as feature 16GB worth of the graphics memory. As a comparison point, the RTX 3080 Mobile’s graphics memory runs at a frequency of 14Gbps. Interestingly, though, the leakster site’s source also seems to suggest that the RTX 3080 Ti Mobile will be higher than average, requiring at least 175W in TGP. Mind you, this amount of power also supposedly accounts for the addition of NVIDIA’s Dynamic Boost 2.0 technology, but it is unclear if this is the actual limit of the GPU and it is likely laptop manufacturers will adjust and fine-tune it as they get closer to their respective launch dates. Beyond that, there doesn’t seem to any additional details about the RTX 3080 Ti Mobile. Based on previous information, though, the laptop GPU is expected to ship out with approximately 7424 CUDA cores, but that detail remains unconfirmed, at the time of this publication.
