Page 2 : Power Consumption, Thermal Output, Noise Level & Benchmarking Notes

Power Consumption

The AMD Radeon RX Vega 56 (Price Check) uses the Vega 10 GPU with 12.5 billion transistors fabricated using the 14 nm FinFET process technology. Even though it’s using a finer process technology than NVIDIA, the extra 5.3 billion transistors need more power.

Hence, the Radeon RX Vega 56 (Price Check) has a TDP of 210 W60 W (40%) more than the GeForce GTX 1070. On a watt per transistor basis, this makes the Radeon RX Vega 56 is 24% more efficient than the GeForce GTX 1070. Of course, what matters more is power efficiency on a watt / performance basis.

Curiously, AMD equipped the Radeon RX Vega 56 (Price Check) with not one, but two 8-pin PCI Express power connectors for a peak power draw of 375 W.

  • The AMD Radeon RX Vega 56 GPUTach

Incidentally, 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 Thermal Output

We recorded the peak exhaust temperature of the AMD Radeon RX Vega 56 (Price Check) and compared it to the GeForce GTX 1070, GeForce GTX 1060 and Radeon RX 480 graphics cards. Take a look.

The AMD Radeon RX Vega 56 temperature

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

Despite its much higher TDP, the AMD Radeon RX Vega 56’s exhaust temperature is just slightly higher than that of the GeForce GTX 1070. That is likely because it uses a more powerful fan with a larger heatsink.

The 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 56 (Price Check) cool. In this video, we recorded the Radeon RX Vega 56 running the Ashes of the Singularity benchmark at the 4K resolution.


Benchmarking Notes

Our graphics benchmarking test bed has the following specifications :

Operating System : Microsoft Windows 10 64-bit

Processor : AMD Ryzen 7 1800X processor running at 3.6 GHz

Motherboard : AORUS AX370-Gaming 5

Memory : 16 GB Corsair Vengeance LPX DDR4-3000 memory (dual-channel)

Storage : 240 GB HyperX Savage SSD

Monitor : Dell P2415Q Ultra HD Monitor

We used the GeForce driver 385.41 for the NVIDIA graphics cards, and Radeon Software 17.9.1 for the AMD graphics cards.
