Today (May/2022) VGA cards are cheaper. RTX series 30xx including 3050, 3060, 3060 Ti, 3070, 3070 Ti, 3080, 3080 Ti, 3090 Of course, for deep learning we consider the size of memory, the number of Cuda cores, and the Tensor core. Interestingly, 3060 has a considerable price of around $330 with 12 GB GDDR6 memory, and 3500k Cuda core. 3060 Ti has priced at $430 with 8GB GDDR6 and 4800k Cuda core. For deep learning with a big model, memory is always the first priority. Though we have less than a haft number of Cuda core for Rtx 3060. The difference in bus width between 3060 and 3060 Ti or later is 192-bit vs 256-bit. That is because the designer employed 6 mem chips for 3060 whereas 8 mem chips for the others. ( Each chip requires 32-bit width)
