GeForce GTX 1660 Ti vs Radeon RX 6600M comparison

In our benchmarks, the GeForce GTX 1660 Ti beats the Radeon RX 6600M in gaming performance.

In our comparison, the Radeon RX 6600M has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6600M 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 Radeon RX 6600M has slightly more memory with 8 GiB of memory compared to 6 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 6600M has a slightly lower TDP at 100 W when compared to the GeForce GTX 1660 Ti at 120 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 1660 Ti is faster than the Radeon RX 6600M.
