The NVIDIA GeForce GTX 1070 Founder’s Edition Up Close

Here are close-up pictures of the various aspects of the NVIDIA GeForce GTX 1070 Founder’s Edition graphics card.

Gamers with older monitors will be glad to note that the GeForce GTX 1070 will come with a dual-link DVI port, in addition to 3 DisplayPorts and a HDMI 2.0B port.

The NVIDIA GeForce GTX 1070 has a TDP of just 150 W, so it only comes with a 8-pin PCI Express power connector. It also has SLI connectors, in case you want to pair two GeForce GTX 1070 cards in SLI mode.


Founder’s Edition Advantage

[adrotate banner=”4″]

The NVIDIA GeForce GTX 1070 Founder’s Edition was designed to be the ultimate expression of NVIDIA’s gaming vision. Hence, they crafted it with premium materials and components, including a faceted die-cast aluminium-framed shroud for strength, rigidity and looks.

Aesthetics aside, the GeForce GTX 1070 Founder’s Edition comes with an improved cooler built around a radial fan and an improved aluminium heatsink. The new heatsink features two copper heat pipes and over 50% more surface area than the GeForce GTX 960.

It also comes with dual FETs for both GPU and memory power supplies, coupled with a low-impedance power delivery network and custom voltage regulators for better power efficiency. All these Founder’s Edition features provide greater overclocking headroom, allowing these cards to hit clock speeds of 2 GHz!


GeForce GTX 1070 Founder’s Edition Thermal Output

The NVIDIA GeForce GTX 1070 uses the new NVIDIA GP104 GPU, which is fabricated on the 16 nm FinFET process. The smaller process technology allowed NVIDIA to stuff almost 50% more transistors into a die that is almost 12% smaller than the previous-generation GPU.

Thanks to the more efficient FinFET process, and the new NVIDIA Pascal architecture which is designed for power efficiency, the GeForce GTX 1070 has a TDP (Thermal Design Power) of just 150 W. We tested this out by recording the peak exhaust temperature of the GeForce GTX 1070 Founder’s Edition, and compared it to the GeForce GTX 1060 and Radeon RX 480 graphics cards, as well as the previous-generation GeForce GTX 980 Ti and Radeon R9 380 graphics cards.

Note that these are not the recorded temperatures, but how much hotter the exhaust air is above ambient temperature.

As you can see, it is a surprisingly cool-running card, producing significantly (6.2°C and 4°C respectively) cooler exhaust air than the previous-generation GeForce GTX 980 Ti and Radeon R9 380 graphics cards.

However, the GeForce GTX 1070 Founder’s Edition produced 4°C hotter exhaust air than the Radeon RX 480, which is also a 150W graphics card.
