XFX has quietly introduced its first new custom Radeon RX Vega 56 and RX Vega 64 video card designs. The custom Radeon RX Vega Double Edition graphics adapters from XFX are not factory overclocked, but have an improved cooling system featuring two fans that may enable a higher overclocking potential when compared to regular air-cooled boards based on AMD’s Vega GPU.

When AMD released its reference Radeon RX Vega 64 and Radeon RX Vega 56 graphics cards earlier this year, the company surprised reviewers and enthusiasts with rather long PCBs (when compared to the Radeon R9 Fury X products) that had a lot of empty space. As it turned out, the RX Vega-series boards need a good cooling and thus a relatively large heatsink. As a result, the company decided to go with a long half-empty PCB to simplify auxiliary PCIe power cable management for end users. As for VRMs, AMD’s reference cards feature a 6+1 phase VRM based on the International Rectifier IR35217 power controller with six IR 3598 phase doublers for the GPU power circuity to maximize efficiency.
