The GeForce GTX 1060
The GeForce GTX 1060 Founders Edition is 9.8 inches (249 mm) long and uses two expansion slots. It uses a centrifugal fan, which is a good choice because it blows the hot air outside the case and, at the same time, allows the using of the contiguous slot without spoiling the card refrigeration.
In Figure 2 you see the video connectors of the GeForce GTX 1060. It has three DisplayPort 1.4, one HDMI 2.0b, and one DVI-D connectors.

In Figure 3 you see the top of the card, where lies a six-pin power connector. The logo lits in green when the computer is powered on.

Figure 4 shows the solder side of the GeForce GTX 1060. As you can see, there are no memory chips at this side. Besides that, it is clear that the PCB is shorter than the cooler.

Figure 6 shows the cooler of the GeForce GTX 1060 FE, with the plastic cover removed. This cooler is actually a big aluminum piece with a radial fan.

In Figure 7 you see the GeForce GTX 1060 with the cooler removed. Notice that there are six memory chips, and two empty spaces for more two chips: this is because the GP106 chip is pin-to-pin compatible with the GP104, used by the GTX 1070 and the GTX 1080. So, the same PCB can be used for any of those cards.
As we mentioned before, the PCB is shorter than the cooler, measuring only 6.8 inches (173 mm). Therefore, it is possible that different manufacturers offer shorter versions of the GeForce GTX 1060.
An interesting detail is that the six-pin PCI Express power connector is not actually at the PCB: it is attached to the cooler and connected do the card by wires.

In Figure 8 you see the GP106 GPU chip, made under 16 nm technology.

Figure 9 shows one of the six memory chips present at the GeForce GTX 1060. It is a Samsung K4G80325FB-HC25 (curiously, the same chip model used at the Radeon RX 480 we tested,) with 8 Gib (1 GiB) capacity each and 4.0 GHz maximum clock (8.0 GHz effective clock). It means the memory chips are already running at their maximum speed, so there is no room to overclock them inside their parameters.

Figure 10 shows the voltage regulator circuit of the GeForce GTX 1060. It uses three phases for the GPU and one phase for the memory chips.
