It might have seemed as though Inno3D had only two Geforce GTX 780 graphics cards up for sale, like Gigabyte, but this isn't the case after all.
There aren't a whole bunch of them like with EVGA, but there is a third model: GeForce GTX 780 iChill.
Revealed by Expreview, it runs the GK110-300 graphics processing unit at 1006 MHz (normally) and 1046 MHz (with GPU Boost 2.0 active).
Everything else is left untouched, performance-wise (192 TMUS, 48 ROPs, 2304 CUDA cores, 3 GB of GDDR5 VRAM at 6 Ghz, 384-bit interface, dual-DVI, HDMI, DisplayPort).
Physically, though, the card has a different cooler, the HerculeZ 3000, with 3 fans. It keeps the product cooler than usual, but brings the price a bit higher, from $649 / €539 / £549. to $659+ / €549 / £559.
