The new RTX 3080 model features 8960 CUDA cores, a 3% bump over the old 10GB model. The upgrade in the memory translates into 20% more bandwidth in GPU, thanks to a wider 384-bit memory bus. The required system power on the 12GB model is still 750W, but it draws an extra 30 watts of power compared to the original RTX 3080.
Other than that, the RTX 3080 is still based on Samsung's 8nm custom process node designed specifically for NVIDIA and features a total of 28 Billion transistors. It also features the next-generation RT (Ray-Tracing) cores, Tensor cores, and brand new SM or streaming multi-processor units.
