Ready for esports and multi-monitor setups

The Sapphire PULSE Radeon RX 550 is an entry-level graphics card built for 1080p online gaming and productivity. It connects through a PCI Express 3.0 slot and drives up to three displays via HDMI 2.0b, DisplayPort 1.4 and DVI. The Polaris-based GPU carries 512 stream processors and a 1206 MHz boost clock.

4GB GDDR5 gives headroom for texture-heavy titles

Four gigabytes of GDDR5 memory on a 128-bit bus run at an effective 1500 MHz for 6.0 Gbps bandwidth. That capacity handles League of Legends, Overwatch, Rocket League and CS:GO at high settings, plus general desktop work at 3840 x 2160 resolution. Heavier AAA games will exhaust the frame buffer and memory bandwidth, forcing lower texture quality.

Cool and quiet for everyday loads

The dual-slot cooler keeps the GPU near its 1206 MHz boost during typical gaming sessions without audible fan rattle. Power draw stays within the PCI Express slot limit so no auxiliary connector is required. Idle temperatures remain low in multi-monitor scenarios thanks to the efficient Polaris architecture.

Questions about this item

Will the PCI Express 3.0 interface on this Radeon RX 550 work with my older motherboard that only has PCIe 2.0 slots?

Yes, the PCI Express 3.0 interface is backward compatible with PCIe 2.0 slots, so the card will function normally on an older motherboard, though it will operate at PCIe 2.0 speeds.

How can I verify the GPU is running at its 1206 MHz boost clock after installation?

Use monitoring software such as GPU-Z or AMD Radeon Software to observe the real-time core clock; under 3D load it should report speeds up to 1206 MHz.

Does the box include any adapters for the HDMI 2.0b, DisplayPort 1.4 or DVI outputs, or must I buy cables separately?

The card provides one HDMI 2.0b, one DisplayPort 1.4 and one DVI port; cables or adapters for those connectors are not included and must be purchased separately.
