Verdict

The RX 6600 and RX 6700 XT land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.

The RX 6700 XT's 12 GB of VRAM is a 4 GB advantage over the RX 6600. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.

Power consumption is a meaningful differentiator here: the RX 6600 draws 132 W versus 230 W for the RX 6700 XT. That 98 W gap can determine whether your existing PSU is sufficient and will show up in long-term electricity costs.

If we had to pick one: the RX 6700 XT edges it on raw VRAM, which carries more weight the longer you hold onto a card.
