The Arktek AMD Radeon RX 550 (4GB) is the same Polaris-generation (GCN 4th generation) entry-level chip as the 4x-HDMI variant listed elsewhere in this range, but in a more conventional display configuration: HDMI, DVI, and DisplayPort, one of each — the standard connector spread most budget cards ship with. It carries 4GB of GDDR5 memory on a 128-bit bus. As with the rest of the RX 550 family, this is a low-power, low-heat card that typically runs without a supplementary PCIe power connector, making it a straightforward drop-in upgrade for a basic office PC that needs real GPU-accelerated video output (dual monitors, video playback, light CAD/2D work) rather than a card built for serious gaming. Its 128-bit memory bus and modest core count place it well below the RX 580/5600/7600XT cards in this same product range on raw gaming performance, but its low power draw, low noise, and low cost make it a sensible choice for general business desktops and HTPC builds.
