What does this comparison mean?
Moving from RX 6600 8GB to RX 7600 XT 16GB increases the recorded result from 133 to 188 FPS and graphics memory from 8GB to 16GB. The uplift is 41.4% in this workload with 8GB more capacity; the benchmark cannot tell us how much of the difference comes from memory rather than the rest of the GPU.
RX 6600 8GB has 8GB and RX 7600 XT 16GB has 16GB 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 7600 XT 16GB
The RX 7600 XT launched in January 2024 with RDNA 3 and 16GB of graphics memory. Its capacity is twice that of the non-XT RX 7600, while benchmark throughput remains a separate comparison.

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.
