Today we have two leaks regarding NVIDIA GeForce GTX 1070. One shows the PCB of the graphics card allows us to compare it with the GeForce GTX 1080. On the other hand, the leak has showcased Overclocking limit of the reference GPU, which is already seen with the GeForce GTX 1080 and also the temperature limit was set at 91 ° C, so in the summer it could cause problem in locations where there are high temperatures.

Regarding the PCB, no surprise, both are essentially the same apart from minor changes in the GeForce GTX 1080, such as cutting the VRM Phase in GTX 1070 to 4 + 1 (Vs 5 + 1 in GTX 1080) and the loss of some component, something which is indicating that NVIDIA has limited the Overclocking potential of GTX 1070 in reference edition, although GTX 1070 still has a lot of headroom in available power coming from single 8pin power connector.

On the other hand, we know that the Pascal GP104-200 GPU core found in the GeForce 1070 GTX Founders Edition will be limited to 112% of the TDP for no particular reason, that means that the maximum frequency would be limited between 1980 and 2050 MHz, which is quite dirty play by the company solely focused to limit the performance of the GeForce GTX 1070 so it will not reach the performance level of GTX 1080. Luckily, as usual, custom models will not arrive neither limited nor with inefficient cooling systems.
