Page 2 : AMD Radeon RX 480 - Size, Thermal Output, Noise Levels
How Big Is It?
For those already measuring their cases to see if the AMD Radeon RX 480 will fit, we measured the card and added the measurements for your convenience.
As you can see, the Radeon RX 480 is “technically” a 7″ long card, but its cooler extends 6.7 cm or 2.65″ beyond the card.
The AMD Radeon RX 480 Thermal Output
The AMD Radeon RX 480 uses the new AMD Polaris 10 GPU, which is fabricated on the latest 14 nm FinFET process. This not only means AMD can stuff more transistors into a smaller chip, it also means lower power consumption and thermal output.
We tested this out by recording the peak exhaust temperature of the Radeon RX 480, its predecessor – the Radeon R9 380, as well as two NVIDIA graphics cards – the GeForce GTX 980 Ti and the new GeForce GTX 1070. Check out the results!
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 relatively cool-running card, producing significantly cooler (8 °C) exhaust air than the Radeon R9 380 graphics card.
But you might wonder – is this because it has a more powerful, and therefore, noisier, fan? Let’s take a look…
The AMD Radeon RX 480 Noise Levels
AMD put a lot of work into reducing the noise levels for the Radeon RX 480. According to them, it is comparable to the noise levels of the NVIDIA GeForce GTX 970 graphics card. Take a look at the table and graph comparing the noise levels of the Radeon RX 480 against the GeForce GTX 970.
But nothing beats hearing it for yourself. So we recorded the sound of the cooler’s blower fan while it’s running the 3D Mark Fire Strike Ultra benchmark.
