RX 6600 vs RX 5600 XT

The RX 6600 is about 20% faster at 1440p. Whether that is worth it depends on the rest of your build.

The gap changes with resolution.

Graphics card differences grow with resolution, because higher resolutions load the GPU harder.

Common questions.

Straight answers on the RX 6600 versus the RX 5600 XT.

• Is the RX 6600 better than the RX 5600 XT?

  +

  Yes, but by less than the spec sheet suggests. At 1440p the RX 6600 scores 36 against 30 for the RX 5600 XT — roughly 20% faster. It also costs about $50 more at MSRP, so the question is whether that gap is worth the money for your build.

• Does the RX 6600 or RX 5600 XT bottleneck a Ryzen 5 9600X?

  +

  Paired with a Ryzen 5 9600X at 1440p, the RX 6600 build comes out 35% GPU-bound, and the RX 5600 XT build comes out 35% GPU-bound. Being GPU-bound is the healthy outcome — it means the graphics card is the part working hardest.

• Is it worth upgrading from the RX 5600 XT to the RX 6600?

  +

  Only if you are also lifting the rest of the build. The RX 6600 is about 20% ahead at 1440p, and gaps like that shrink further at 4K where the GPU does more of the work. If you are upgrading from the RX 5600 XT purely for frames, check the pairing first.

• Which is better value, the RX 6600 or the RX 5600 XT?

  +

  On performance per dollar at MSRP, the RX 6600 wins. The RX 6600 lists at $329 for an index of 36, and the RX 5600 XT at $279 for 30.
