We have been hearing about mining cards for months now. These computing-oriented cards are not available in most countries due to limited 3-month warranty they are offered with. The P106 mining cards are basically stripped down GTX 1060s without display connectors. This makes the design process simpler and cheaper. Together with this limited warranty, they should be a great choice for miners. However unlike the GTX series, they cannot be used for gaming when mining becomes unprofitable.

Although we have been seeing traces of other mining cards (such as P102-100, P104-100) only the P106-100 and P106-090 have made the appearance. So far the specs of the latter were unknown, but thanks to Inno3D we finally get to see how effective these cards would potentially be for mining.

Starting with CUDA core count, the P106-090 is equipped with only 768 shaders. That’s way fewer than P106-100 and GTX 1060 3GB (1152). In fact, that’s the same core count as GTX 1050 Ti. This shows how effectively NVIDIA is selling all chips, even those with 40% of cores disabled.

There is one advantage of the P106-090 over GTX 1050 Ti and that’s memory bus width. Unlike the GP107-based model, the P106-090 features 192-bit bus. Memory speed is important for mining efficiency.

According to Inno3D the TDP of P106-090 is only 75W, which (theoretically) makes the power connector optional. However, since most mining cards are connected through PCIe x1 risers, external power is more of a requirement than a feature. That’s why all Inno3D Crypto Mining cards are using 6-pin power connectors.

Inno3D has two P106-090 cards, a single-fan mini-ITX model called Compact and a slightly bigger card with dual-fan cooler named Twin X2.
