Nvidia TITAN V
If you want the absolute fastest graphics card money can buy and you have deep pockets, the TITAN V from Nvidia is the best on the market. The card features 12 GB of HBM2 memory, and it produces a full 110 teraflops of computing power. Its cores operate at 1,200 MHz, with the potential to boost to 1,455 MHz.
With such power, you may be surprised to learn that the card isn’t designed for gamers, but rather scientists, who require its advanced computational capabilities. If you can swallow its steep price, this graphics card is the most powerful PC GPU available.
