Gigabyte GeForce GTX 780 Ti GHz Edition Detailed
Gigabyte, which gave the GeForce GTX 780 the "GHz Edition" treatment, in which the GPU core is factory-overclocked above the 1 GHz mark, meted out the same with the more powerful GTX 780 Ti. Positioned above the GTX 780 Ti OC Edition which debuted early last month, the GHz Edition features a swanky new custom-design PCB by Gigabyte, which features a strong VRM; coupled with the same WindForce 450W cooling solution that's featured on the GTX 780 GHz Edition. The GTX 780 Ti OC Edition, on the other hand, is a combination of the WindForce 450W cooler and NVIDIA reference PCB, with a factory-overclock.
The PCB of Gigabyte GTX 780 Ti GHz Edition is a bustling metropolis, with a 10+2 phase VRM that draws power from a pair of 8-pin PCIe power connectors. The cooler, on the other hand, is a complex aluminium fin-stack heatsink to which heat is fed by five 8 mm-thick copper heat pipes, and which are ventilated by a trio of 100 mm fans.The large heatsink is supported by a base plate that draws heat from the memory and VRM; a support brace that runs along the top of the card, and a back-plate. Gigabyte tuned the card with clock speeds of 1085 MHz core (base), 1150 MHz core (GPU Boost), and a surprisingly untouched 7.00 GHz (GDDR5-effective) memory. Based on the 28 nm GK110 silicon, the GTX 780 Ti features 2,880 CUDA cores, 240 TMUs, 48 ROPs, and a 384-bit wide GDDR5 memory interface, holding 3 GB of memory. There's no word on when Gigabyte will formally launch this card. It shouldn't be too far away.
