The Vega 64 Power Consumption
The AMD Radeon RX Vega 64 (Price Check) uses the Vega 10 GPU with 12.5 billion transistors fabricated using the 14 nm FinFET process technology. That’s 500 million transistors more than the NVIDIA GP102 GPU powering the NVIDIA GeForce GTX 1080 Ti.
AMD equipped the Radeon RX Vega 64 (Price Check) with two 8-pin PCI Express power connectors for a peak power draw of 375 W. This will come in handy if you intend to overclock, although keeping the GPU cool will be a challenge.
There is a GPUTach LED light strip right next to the two 8-pin PCI Express power connectors, which tells you the GPU load at a glance. There are two switches nearby that allows you to turn it on or off, and switch between the red and blue LED colours.
The Vega 64 Thermal Output
We recorded the peak exhaust temperature of the AMD Radeon RX Vega 64 (Price Check) and compared it to the GeForce GTX 1080 Ti, GeForce GTX 1070, Radeon RX Vega 56 (Price Check), the GeForce GTX 1060 and the Radeon RX 580 graphics cards. Take a look.
Note that these are not the recorded temperatures, but how much hotter the exhaust air is above ambient temperature.
With its higher TDP, it’s no surprise that the Radeon RX Vega 64 (Price Check) has the highest exhaust temperature in this comparison – 2.8 °C higher than the GeForce GTX 1080 Ti, and 5.4 °C higher than Vega 56 (Price Check).
The Vega 64 Noise Level
Needless to say, you will be wondering about the noise level of the more powerful cooler used to keep the Radeon RX Vega 64 (Price Check) cool. In this video, we recorded the Radeon RX Vega 64 running the Ashes of the Singularity benchmark at the 4K resolution.
Our graphics benchmarking test bed has the following specifications :
We used the GeForce driver 385.41 for the NVIDIA graphics cards, and Radeon Software 17.9.1 for the AMD graphics cards.
