PowerColor builds only AMD Radeon cards, from Hellhound to Red Devil. Every pick is a PowerColor card, ordered by VRAM.
We sorted these picks by GPU, VRAM and memory, working from the makers' own data; nothing here was tested in-house, and if a maker skips length, the guide says so.

How We Chose These Powercolor Graphics Cards
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- How these picks were ranked
- We lined up four cards on GPU, video memory, memory and card length from manufacturer specifications. We did not test them in-house, and card length and recommended power supply are missing for at least one pick.
- The shared baseline
- All 4, from the PowerColor Hellhound 7900 XTX to the PowerColor 7800 XT Twin Fan, state GPU, video memory and memory and share GDDR6 memory.
- Where the specs have gaps
- The PowerColor 7900 XT and the PowerColor Fighter 7800 XT give no card length; the PowerColor Fighter 7800 XT gives no recommended power supply.
- Price range
- At our last check the picks ran from the PowerColor Fighter 7800 XT ($500 to $1000) to the PowerColor Hellhound 7900 XTX ($1000 to $1500).
