The GeForce GTX 780 is based on GK110-300-A1 graphical solution , which contains 2,304 core CUDA, 48 ROP units and a 384-bit memory controller. The base GPU frequency is 863 MHz , a dynamic overclocking rises value to 902 MHz, the volume of on-board memory is 3 GB GDDR5 memory chips operate at an effective frequency of 6008 MHz. In addition, the video card has a 6 - and 8-pin power connector, two video outputs DVI, one HDMI and one DisplayPort, and a TDP of 250 watts.
On the speed level GeForce GTX 780 will surpass rival the Radeon HD 7970 GHz Edition by between 25% to 50% (the smallest gap - 20% - is observed in the game Tomb Rider).
As expected, the GeForce GTX 770 is based on GK104 processor with 1536 cores CUDA, but its base frequency will be increased to 1046 MHz (up to 1,085 MHz under the influence of GPU Boost 2.0 technology). Effective memory frequency will be increased to 7000 MHz, on sale will be available 2 GB or 4 GB versions.
GeForce GTX 770 is faster than the Radeon HD 7970 GHz Edition by the value of 10-20%, in some games (Crysis 3, Max Payne 3, and Tomb Rider) while in other the difference is insignificant. In this case, both the video card cost should be comparable. Related Products :
