VRAM
RX 6600: 8GB of VRAM is enough for ultra textures at 1080p, enough for high (not ultra) textures at 1440p and below the 12GB our VRAM rule asks for at 4K high settings, so expect to lower texture quality there.

With Your CPU
A faster card only pays off when your CPU can feed it. Here is each card with common processors in our bottleneck engine (typical AAA game, high settings). “GPU-limited” is normal; a CPU % is how much of the card goes unused.

Power and PSU
With a Ryzen 5 7600, the PSU Calculator recommends 500W for a PC with the RX 6600 and 550W with the RX 7600. The makers’ own recommendations are 500W and 550W.
Which Should You Buy?
- Buy the RX 7600 for more performance: about 12% higher in our index. It is worth it if the price difference is smaller than that.
- The RX 6600 makes sense when it costs clearly less, or when its other strengths below matter more to you.
- Not sure your CPU keeps up? Check your exact pair in the PC Bottleneck Calculator.
