What does this comparison mean?
The RX 6600 and this 14 Gbps BIOS version of the RX 5600 XT are fairly close in the benchmark. The RX 6600 adds 2GB of memory, but this result does not suggest a dramatic speed upgrade on its own.
RX 5600 XT 6GB (14Gbps BIOS) has 6GB and RX 6600 8GB has 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 5600 XT 6GB (14Gbps BIOS)
This row represents the RX 5600 XT 6GB at 14 Gbps. Sapphire documented that configuration through a January 2020 BIOS update for specific matching PULSE board part numbers.
RX 6600 8GB
The RX 6600 is an RDNA 2 desktop GPU with 8GB of GDDR6, introduced in October 2021.

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. RX 5600 XT 6GB (14Gbps BIOS) uses the 27-card Radeon RX 5600 XT 6GB family total; GPUsed has not split it by this exact variant. Full benchmark method.
