Radeon RX 6600M vs GeForce GTX 780 specs and performance

In our benchmarks, the Radeon RX 6600M beats the GeForce GTX 780 in gaming performance.

In our comparison, the Radeon RX 6600M has a significantly 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 Radeon RX 6600M also has a significantly 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 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 significantly lower TDP at 100 W when compared to the GeForce GTX 780 at 250 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 6600M is faster than the GeForce GTX 780.
