GeForce GTX 1660 vs Radeon RX 6700M specs and performance

For gaming, the Radeon RX 6700M graphics card is better than the GeForce GTX 1660 in our tests.

Our database shows that the GeForce GTX 1660 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. Despite this, the Radeon RX 6700M has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, the Radeon RX 6700M has significantly more memory with 10 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 has a slightly lower TDP at 120 W when compared to the Radeon RX 6700M at 135 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6700M is faster than the GeForce GTX 1660.
