True 4D Image Denoising on the GPU

Table 1

Comparison between three Nvidia GPUs, from three different generations, in terms of processor cores, memory bandwidth, size of shared memory, cache memory, and number of registers; MP stands for multiprocessor and GB/s stands for gigabytes per second. For the GTX 580, the user can for each kernel choose to use 48 KB of shared memory and 16 KB of L1 cache or vice versa.
