Verdict

The Gigabyte GeForce GTX 1660 Super OC is a factory-overclocked mid-range graphics card based on the NVIDIA Turing architecture, featuring 1,408 CUDA cores and an increased boost clock of 1,830 MHz compared to the reference 1,785 MHz. It is equipped with 6GB of high-speed GDDR6 memory on a 192-bit interface, delivering a significant 336 GB/s bandwidth for smooth 1080p gaming performance. The card utilizes Gigabyte's Windforce 2X cooling system with alternate spinning 90mm fans and a protection backplate for enhanced thermal efficiency and structural integrity. Main pros include its excellent price-to-performance ratio, near-GTX 1660 Ti performance levels, and quiet, cool operation under load. However, notable cons include its lack of dedicated hardware for ray tracing and DLSS, as well as the 6GB VRAM limit which may struggle with the most demanding ultra-texture settings in modern AAA titles.
