Positions in all rankings

Common positions NVIDIA GeForce GTX 1660 Ti GPU in popular benchmarks, for comparison with other models.

No data

Blender Open Data

Official median of community submissions; higher is better. Blender versions, operating systems and compute backends remain separate.

Blender 5.2.0 / OPTIX / Windows: 694.004899 samples/min submissions: 11; snapshot: 2026-10-01 Official source

Snapshot date is the retrieval date, not the measurement date. Individual dates, RAM, drivers and power limits are unknown. This aggregates different user systems; it is not a test of a specific partner board and is excluded from the legacy composite index.

Benchmarks

Performance tests GPU

No comparable legacy benchmark results are available.

These are saved results from the earlier catalog. Measurement dates and test configurations were not recorded. Models with no comparable results are omitted.

Recent models: test results with identified primary sources — Game frame rates

Comparable benchmark results are required to suggest performance alternatives.

Base Clock is the base GPU frequency stated by the manufacturer for this model.

Boost Clock describes automatic frequency increases. Actual clock speed varies with workload, temperature and power limits; it is not a guarantee of manual overclocking.
