Introduction
AMD's Radeon RX480 Series was released in late June and is the company's first graphics card based on its new "Polaris" GPU architecture, and its first chip built on the 14 nanometer FinFET process. It is also the first AMD GPU made at GlobalFoundries, which is a deviation from the year-long relationship with TSMC.
The silicon driving the RX 480, which is based on "Polaris," is codenamed "Ellesmere" and is externally referred to by AMD as "Polaris 10." Polaris 10 on the Radeon RX 480 comes with 2304 shaders enabled, 144 texture units and 32 ROPS that are connected to a 256-bit wide memory bus with 8 GB of GDDR5 memory.
In this review, we are taking a look at the MSI RX 480 Gaming X, a custom-design Radeon RX 480. We've tested many MSI Gaming cards in the past and nearly all of them impressed with good temperatures and low noise levels. Let's hope MSI can pull it off on the RX 480 as well, a card where many AIBs have failed to produce good board designs that can compete with NVIDIA's GTX 1060 offerings.
MSI has told us pricing of their RX 480 Gaming X to be $259-$269, so we'll be using $265 throughout this review.

The Card
We've seen MSI's new TwinFrozr thermal solution on the company's GTX 1060, 1070, and 1080, and it looks great due to MSI's attention to little details. On the back, you will find a sturdy metal backplate. Dimensions of the card are 28 cm x 14 cm.
Installation requires two slots in your system.
Display connectivity options include a DVI port, two HDMI ports, and two DisplayPorts. Note that one DisplayPort has been switched to HDMI. This is to cater to users who are looking to either run two VR headsets or a VR headset and a TV off their graphics card. It's also good to see a DVI connector included, something the reference design lacks.
The HDMI port is now version 2.0b, and DisplayPort has been updated to 1.3 HBR3/1.4 HDR ready, which enables support for 4K @ 120 Hz and 5K @ 60 Hz, or 8K @ 60 Hz with two cables. GPU accelerated encoding is now supported for H.264 at up to 4K30, and HEVC is supported at up to 4K60. Accelerated decoding is supported for HEVC at up to 4K60 Main-10, VP9 is supported at up to 4K, and H.264 works at up to 4K120.
AMD CrossFire has been running over the PCI-Express bus for a few generations now. The Polaris Series is no different.
