NVIDIA is allegedly preparing a new variant of GTX 1060.

NVIDIA GeForce GTX 1060 5GB for Internet cafés

A new model, which is actually the fourth installment under GTX 1060 brand, is said to retain the full core count of GP106 GPU — 1280 — while using shorter bus width and smaller frame buffer. The GTX 1060 5GB is rumored to be using GP106-350 GPU variant (as pictured below). This GPU would have 160-bit bus width and it would be tied with 5GB GDDR5 memory.

The new variant of GTX 1060 is an exclusive model for the Chinese market, where the popularity of Internet cafés is booming. These cards are to be sold in bigger quantities, hence no fancy packaging to be expected (so in that regard it would be similar to P106-100 mining series).

Expreview has confirmed that GTX 1060 5GB will use 1280 CUDA cores. This should be enough for solid 1080p gaming at higher settings. It is a scenario where 1060 3GB is clearly lacking performance.
