GeForce 920MX vs GeForce RTX 4090 specs and performance

According to the hardwareDB Benchmark, the GeForce RTX 4090 GPU is faster than the GeForce 920MX in gaming.

The GeForce RTX 4090 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 GeForce RTX 4090 also has a significantly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

In addition, the GeForce 920MX has a significantly lower TDP at 16 W when compared to the GeForce RTX 4090 at 450 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the GeForce RTX 4090 is better than the GeForce 920MX.
