It looks like NVIDIA’s upcoming GeForce RTX 4080 graphics card will come in two different variants based on memory size, memory bus width, and even core configuration. According to reports, there are two reference designs for the RTX 4080, one will have 16 GB of memory and a 12-layer PCB, while the other will have 12 GB of memory and a 10-layer PCB.
It also looks like both cards are launching at the same time, which is very similar to NVIDIA’s GTX 1060 series which came in 3GB and 6GB variants. Of course we saw that NVIDIA also released two different RTX 3080 models, one with 10GB of RAM and the other with 12GB. These cards also had different CUDA core counts, which we might see here as well.
