Radeon RX 6600 vs GeForce 940MX benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6600 GPU is faster than the GeForce 940MX in gaming.

In our comparison, the Radeon RX 6600 has a significantly 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 6600 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.

In addition, the GeForce 940MX has a significantly lower TDP at 23 W when compared to the Radeon RX 6600 at 132 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6600 is faster than the GeForce 940MX.
