RX 6600 vs RTX 3070

The RX 6600 and RTX 3070 land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.

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.
