Amd radeon rx 480, pcb details

We already have in image the PCB that will be used in the new graphics cards with AMD Polaris architecture, the Radeon RX 480 and RX 470. As for the Radeon RX 460, it is expected that it will use a different version of the simpler PCB due to its lower needs.

AMD Radeon RX 480 uses a PCB with a 6 + 1 phase VRM

The new AMD PCB will serve to house the new Ellesmere GPU manufactured in Global Foundries' 14nm FinFET + process and with a 256-bit interface for GDDR5 memory. Everything indicates that the Radeon RX 480 and RX 470 will share the same PCB. On the new AMD PCB we see a total of eight memory chips for 4GB and 8GB configurations. In terms of power supply we see a single 6-pin connector to power a 6 + 1 phase VRM, even more so than the GeForce GTX 1080 (5 + 1) with a TDP of 180W and a noticeably higher power need. AMD wanted to create a fairly robust VRM to ensure excellent performance and avoid annoying Coil Whine, hopefully the quality of the phases is up to scratch.

We recommend reading our guide to the best graphics cards by ranges.

As for the video outputs of the reference PCB we appreciate four connectors in the form of 3 x DisplayPort 1.3 / 1.4HDR and 1x HDMI 2.0.
