What does this comparison mean?
The RX 6600 and RX 6600 XT both offer 8GB within RDNA 2, while the XT leads this benchmark. The decision is therefore about the different GPU configurations and actual offers, not a memory-capacity upgrade or an assumption that all RX 6600 names describe the same card.
Both variants have 8GB of graphics memory. Memory capacity, board dimensions, power connectors and the price of a particular used card are separate from this benchmark. Compare the exact item before deciding whether to upgrade.
The two GPUs in context
RX 6600 8GB
The RX 6600 is an RDNA 2 desktop GPU with 8GB of GDDR6, introduced in October 2021.
RX 6600 XT 8GB
AMD introduced the RX 6600 XT in August 2021 with RDNA 2 architecture and 8GB of GDDR6. It sits separately from the RX 6600 and the later RX 6650 XT.

How the figures are compared
Both FPS figures come from the owner-supplied GPUsed benchmark dataset. GPUsed reports a continuous FurMark run at 1080p for its physical-card checks. The percentage compares the higher model average with the lower one using the original FPS values. Our rating uses a compressed scale, with the fastest GPU at 100; it is separate from the percentage difference. A benchmark result does not predict gaming FPS.
GPUsed reports its physical-card checks typically last 30 to 60 minutes while temperature and stability are checked. The owner supplied the model-level FPS workbook on 2 October 2026; this benchmark dataset was last reconciled 3 October 2026. Historical cards tested are separate from the number of FPS runs behind a model average. Full benchmark method.
