NVIDIA's newest Titan GPU is now available for purchase, and the company says it's the "world's most powerful GPU for the PC" yet. The GPU-maker has launched the Volta-powered Titan V at the annual Neural Information Processing Systems conference. Volta is NVIDIA's latest microarchitecture designed to double the energy efficiency of its predecessor, and Titan V can apparently deliver 110 teraflops of raw horsepower or around 9 times what the previous Titan is capable of. This powerful new GPU's target? Scientists and researchers working on AI, deep learning and high performance computing.
