Technical data / specifications

With the EVGA GTX 680 Superclocked you get a factory overclocked card, which is based on NVIDIAs latest GK-104 chip, that is being manufactured at TSMC using 28 nanometer structures. Most factory overclocked card feature either a modified cooler, a modified PCB or both. With the GTX 680 Superclocked EVGA chose to modify neither of these things. The card comes with the NVIDIA reference design and cooler.

Looking at cock speeds we see that the GPU runs at 1'058 MHz standard and 1'124 MHz boost clock. The GDDR5 memory clocks at 6'208 MHz. Furhtermore there is 256 bit memory interface which results in 198'656 Megabyte per second memory bandwidth. In total there is 2'048 Megabyte of GDDR5 memory.

The GPU itself consists of 3.54 billion transistors. The architectural hierarchy starts with a so called GigaThread Engine, which marshals processed and unprocessd information between the GPU and the PCI-Express 3.0 system interface. Further down in the hierarchy there are four Graphics Processing Clusters (GPCs), which can be seen as a common resource. At this point you'll also find a the raster eingine and two streaming multiprocessors (SMs). Altough NVIDIA decided to change their name which means that they're now called SMX.
