GeForce GTX 1660 Ti vs GeForce RTX 2070 comparison
According to the hardwareDB Benchmark, the GeForce RTX 2070 GPU is faster than the GeForce GTX 1660 Ti in gaming.
Our database shows that the GeForce GTX 1660 Ti has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the GeForce GTX 1660 Ti also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.
Next up, in terms of GPU memory, the GeForce RTX 2070 has slightly more memory with 8 GiB of memory compared to 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.
In addition, the GeForce GTX 1660 Ti has a significantly lower TDP at 120 W when compared to the GeForce RTX 2070 at 175 W. Heat output doesn't match power consumption directly but, it's a good estimate.
In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce RTX 2070 over the GeForce GTX 1660 Ti.
