Radeon RX 550X vs GeForce GTX 750 specs and performance

In our benchmarks, the GeForce GTX 750 beats the Radeon RX 550X in gaming performance.

Our database shows that the Radeon RX 550X 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. In addition, the Radeon RX 550X also has a slightly 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.

Next up, in terms of GPU memory, the Radeon RX 550X has significantly more memory with 4 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 550X has a slightly lower TDP at 50 W when compared to the GeForce GTX 750 at 55 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 750 is better than the Radeon RX 550X.
