Verdict

The XFX Radeon RX 590 Fatboy is a mid-range graphics card based on the 12nm Polaris 30 architecture, featuring 2,304 stream processors and a factory-overclocked boost clock of 1580 MHz. It is equipped with 8GB of GDDR5 memory on a 256-bit bus, delivering 256 GB/s bandwidth, and utilizes a bulky 2.5-slot cooling system with dual 100mm fans and a solid aluminum backplate. Main pros include its exceptional 1080p and capable 1440p gaming performance, outperforming the GTX 1060, along with a dual BIOS switch that offers a choice between high-performance and silent cooling modes. However, the card is notably power-hungry with a 225W TDP requiring both 8-pin and 6-pin connectors, can run quite hot under full load, and its large physical footprint may not fit into smaller PC cases.
