GeForce GTX 660 vs Radeon RX Vega 11 specs and performance

In our benchmarks, the GeForce GTX 660 beats the Radeon RX Vega 11 in gaming performance.

Our database shows that the GeForce GTX 660 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. Despite this, the Radeon RX Vega 11 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.

In addition, the Radeon RX Vega 11 has a significantly lower TDP at 15 W when compared to the GeForce GTX 660 at 140 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 GeForce GTX 660 is faster than the Radeon RX Vega 11.
