Dedicated mining graphics cards are not new, delivering shorter warranties, and a diminished feature set when compared to their gaming-oriented equivalent. The benefit of these cards is their lower pricing, as well as potential power savings due to the lack of several unnecessary components, which is ideal for cryptocurrency miners where profit is key.
Gigabyte has now revealed their GV-NP104D5X-4G graphics card, delivering some unique specifications derived from Nvidia's GP104 silicon. What Gigabyte is offering here is a graphics processor with the same CUDA core count as a GTX 1070 with GDDR5X memory, delivering specifications that are somewhere between a GTX 1070 and GTX 1080. The GPU itself only comes with 4GB of VRAM, which will help to make the card more affordable and will feature 4x PCIe 3.0 wiring, which is much less than the 16 lanes that gaming oriented graphics cards utilise.
Aside from these the direct downgrades in VRAM capacity and PCIe bandwidth, this graphics card also comes with no display outputs, making this card useless for anything outside of compute. The card comes with a single 8-pin PCIe connection for power and uses a simple aluminium heat stack with a triple fan cooler design.

Doesn't interest me in the slightest but I am sure it does some people.
