AMD Radeon RX 480 8GB Review – Polaris Is Here
AMD Radeon RX 480 – Closer Look
The Radeon RX 480 sample we got here came straight from AMD, so no retail packaging or box, just the card itself. As you can see, the PCB is shorter than its cooler shroud.
This is a reference design, so there are no backplate or any bling, just the new, clean and sleek look of the RX 480 that reminds me of the Fury’s cooler shroud. A single 6-pin connector is located at the end of the PCB which is rated to draw around 150W of power.
There were some issues with the RX 480’s power draw based on the tests conducted by other reviewers. At this point in time, AMD has already addressed the issue and has released a new driver, Radeon Software Crimson 16.7.1, that fixes the power draw issues.
At the output ports, the Radeon RX 480 has three DisplayPorts and an HDMI port. The DisplayPorts are 1.3 HBR3/1.4 HDR ready, while the HDMI port is now version 2.0b. The DisplayPorts should be able to support 4K UHD resolution at 120 Hz and 5K resolution at 60Hz, or even 8K resolution at 60Hz with the use of two cables.
The reference Radeon RX 480 features a reference blower type cooler. The GPU is cooled by an aluminum heatsink, including the memory and other components as well. I won’t be focusing much on the reference cooler since aftermarket coolers are still (far) better than the reference one, specially when it comes to cooling the GPU.
Here we have a closer look at the PCB of the Radeon RX 480. It doesn’t have a long PCB, after all it’s a mid-range graphics card. You can see that there are 8 physical memory chips indicating that this is an 8GB version. Also for those who are not updated in terms of CrossFire, AMD has removed the CF bridges on the PCB (starting with the R9 200 series). CrossFire is still supported, but the link is already done via the PCIe interface.
Here’s a closer look on the 14nm GPU die and Samsung’s GDDR5 memory. Now it’s time to see how this card performs on the following pages.
