Verdict
At $595.00, the RX 6600 costs about 8% less than the $645.00 RTX 3070. That $50.00 saving is real money, but not so wide that the pricier card is out of reach.
Power consumption is a meaningful differentiator here: the RX 6600 draws 132 W versus 220 W for the RTX 3070. That 88 W gap can determine whether your existing PSU is sufficient and will show up in long-term electricity costs.
As an NVIDIA card, the RTX 3070 gives you access to DLSS 4 super-resolution and Frame Generation, which can meaningfully lift frame rates in supported titles. The RX 6600 counters with FSR 4, which is open-source and works across a wider range of games — including some that don't support DLSS. Which ecosystem matters more depends on the games in your library.
