The NVIDIA GeForce GTX 1080 Ti Up Close
In this video, we are going to take a quick look at the NVIDIA GeForce GTX 1080 Ti Founders Edition graphics card (Price Check), and its faceted die-cast aluminium cooler.
Here are close-up pictures of the various aspects of the NVIDIA GeForce GTX 1080 Ti Founders Edition graphics card (Price Check).
Unlike the GeForce GTX 1070 or GeForce GTX 1060, the GeForce GTX 1080 Ti does not come with any dual-linked DVI port. It only has three DisplayPort 1.4 and one HDMI 2.0b ports. That’s where the DisplayPort to DVI adaptor comes in.
The NVIDIA GeForce GTX 1080 Ti (Price Check) has a TDP of 250 W, and requires both 8-pin and a 6-pin PCI Express power cables. It also supports the SLI HB (High Bandwidth) bridge for two-way SLI pairing.
Founder’s Edition Advantage
The NVIDIA GeForce GTX 1080 Ti Founders Edition (Price Check) 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 1080 Ti Founders Edition comes with an improved cooler built around a radial fan and an improved aluminium heatsink. The new heatsink features vapour chamber cooling and has 2x the surface area.
It also boasts a 7-phase power design with 14 high-efficiency dual FETs for both GPU and memory power supplies. Coupled with a low-impedance power delivery network and custom voltage regulators, they deliver better power efficiency and overclocking headroom.
The Thermal Output
The NVIDIA GeForce GTX 1080 Ti (Price Check) uses the NVIDIA GP102 GPU, which is fabricated on the 16 nm FinFET process. Thanks to the more efficient FinFET process, and the new NVIDIA Pascal architecture which is designed for power efficiency, the GeForce GTX 1080 Ti has a TDP (Thermal Design Power) of just 250 W.
We recorded the peak exhaust temperature of the GeForce GTX 1080 Founders Edition, and compared it to the Radeon RX Vega 64 (Price Check) and Vega 56 (Price Check) graphics cards, as well as the older GeForce GTX 1070, GeForce GTX 1060 and Radeon RX 580 graphics cards.
Note that these are not the recorded temperatures, but how much hotter the exhaust air is above ambient temperature.
Despite having a 15% lower TDP than the AMD Radeon RX Vega 64 (Price Check), the GeForce GTX 1080 Ti is a cooler-running card, producing 2.8°C cooler exhaust air than the previous-generation GeForce GTX 980 Ti graphics card. In fact, its peak exhaust temperature was just 2.6°C hotter than the exhaust air from the Vega 56 (Price Check) graphics card.
The Noise Level
Of course, the lower exhaust temperature might be due to a more powerful, and therefore, noisier, fan. Let’s see how noisy the GeForce GTX 1080 Ti Founders Edition fan really is…
In the video above, the GeForce GTX 1080 Ti Founders Edition (Price Check) was recorded while it was running the 3D Mark Time Spy benchmark. As you can hear, the fan spools up quite a bit at times, but it is still quieter than the Vega 64 (Price Check).
