Which should you buy?
Buy the RX 7600 if you want the higher frame rate and can find it at a fair price. Choose the RX 6600 if it is clearly cheaper and its 8GB+ of VRAM and features cover your target resolution. Both are from a similar lineage, so price is the main deciding factor.

RX 6600 vs RX 7600 at each resolution
| Resolution | RX 6600 | RX 7600 |
|---|---|---|
| 1080p | Great (8 short of Excellent) | Great (2 short of Excellent) |
| 1440p | Not ideal (6 short of Playable) | Playable (10 short of Good) |
| 4K | Not ideal (18 short of Playable) | Not ideal (12 short of Playable) |
The 6-point gap (32 vs 38) changes the verdict at 1440p: that is where the RX 7600 earns its place. At 1080p and 4K both get the same rating, so paying for the faster card buys headroom rather than a different experience there.
Power, PSU and efficiency
Reference board power is 132W for the RX 6600 and 165W for the RX 7600, a 33W difference. Per 100W that works out to 24.2 index points for the RX 6600 and 23 for the RX 7600, so the RX 6600 does more per watt. An existing 450W supply meets the maker guidance for the RX 6600 but not for the RX 7600 (550W). Full sizing: RX 6600 PSU · RX 7600 PSU.

Frequently asked questions
Is the RX 6600 better than the RX 7600?
On our relative index the RX 7600 is about 19% ahead of the RX 6600. Both carry 8GB of VRAM. The smaller the gap, the more other factors like price, VRAM and features should decide it.
Which is better value, the RX 6600 or the RX 7600?
Value depends on the price you can find each at. The slower card is usually the smart buy if it is meaningfully cheaper, unless you need the extra VRAM or features of the faster one.
Do the RX 6600 and RX 7600 need different power supplies?
The RX 6600's maker lists a 450W supply and the RX 7600's lists 550W; our starting classes are 450W and 550W. If you might move to the RX 7600 later, size for its 550W now.
