Vigile writes "NVIDIA's new GeForce GTX TITAN graphics card is being announced today and is utilizing the GK110 GPU first announced in May of 2012 for HPC and supercomputing markets. The GPU touts computing horsepower at 4.5 TFLOPS provided by the 2,688 single precision cores, 896 double precision cores, a 384-bit memory bus and 6GB of on-board memory doubling the included frame buffer that AMD's Radeon HD 7970 uses. With a make up of 7.1 billion transistors and a 551 mm^2 die size, GK110 is very close to the reticle limit for current lithography technology! The GTX TITAN introduces a new GPU Boost revision based on real-time temperature monitoring and support for monitor refresh rate overclocking that will entice gamers and with a $999 price tag, the card could be one of the best GPGPU options on the market." HotHardware says the card "will easily be the most powerful single-GPU powered graphics card available when it ships, with relatively quiet operation and lower power consumption than the previous generation GeForce GTX 690 dual-GPU card."
