NVIDIA GTX 1080Ti Specifications Leaked, showing 12GB GDDR5 Memory

NVIDIA’s GTX 1080 Ti’s specifications have been leaked, showcasing a GPU with 12GB of GDDR5 memory and 3328 CUDA cores.

The NVIDIA GTX 1080 Ti will feature the NVIDIA’s GP102 GPU, which will have 768 more CUDA cores than the GTX 1080 and 256 less CUDA cores than the GTX Titan X Pascal.  NVIDIA has made two significant changes with the GTX 1080 Ti, changing the GDDR5X memory to slower GDDR5 and taking away 4 SM units from the GPU, compare to GTX Titan X Pascal.

The change to GDDR5 memory will give the GTX 1080 Ti 384GB/s of memory bandwidth, which is a significant reduction in bandwidth when compared to the GTX Titan X Pascal, which has 480GB/s of bandwidth.

But still, the GTX 1080Ti will have significantly more memory bandwidth than the GDDR5X used in GTX 1080, so the downgrade to GDDR5 will not affect the GTX 1080Ti performance than the GTX 1080 newer memory technology.

We still don’t know when NVIDIA plans to release their GTX 1080 Ti but expect NVIDIA to wait until AMD launches their high-end competitor.
