Verdict
With the RX 6700 XT running 26% above the RX 6600 — a $204.00 premium — the two cards sit in meaningfully different price brackets. The RX 6600 wins on value unless the extra performance matters for your workload.
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.
Unless you specifically need what the RX 6700 XT offers, the RX 6600 is the stronger value at this price gap.
