Sapphire Radeon 11265-05-20G Pulse RX 580 8GB GDDR5 Dual HDMI/ DVI-D/ Dual DP OC

Bottom line: The Sapphire Radeon 11265-05-20G Pulse RX 580 8GB GDDR5 Dual HDMI/ DVI-D/ ($439.00 on Amazon as of 2026-10-07): 8GB GDDR5 on a 256-bit bus — headroom for 1080p texture settings; main trade-off: under 225W board power means a real PSU, not a bundled unit.

SpecPicks Verdict

SpecPicks scored Sapphire Radeon 11265-05-20G Pulse RX 580 8GB GDDR5 Dual HDMI/… using a rating × review-volume × price-fit model applied to published specs and reviews across the retro graphics cards category. Sapphire's retro graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How much VRAM does the Sapphire Pulse RX 580 have?

8GB of GDDR5 on a 256-bit memory bus, which is the larger of the two RX 580 memory configurations.

What monitors can I connect to it at once?

It has five outputs: two HDMI, two DisplayPort, and one DVI-D, so you can run a multi-monitor setup and still drive an older DVI panel directly.

Sapphire rates power consumption at under 225 watts for the card. Check the product listing for the exact PCIe power connector requirement before buying.

Does it work with Windows 7?

Yes. Sapphire lists both Windows 10 and Windows 7 support, which is unusual for graphics cards and useful for legacy or period-correct builds.
