Radeon RX 460 vs GeForce GTX 660 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 460 GPU is faster than the GeForce GTX 660 in gaming.

In our comparison, the Radeon RX 460 has a slightly 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 460 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 460 has slightly more memory with 4 GiB of memory compared to 3 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 460 has a significantly lower TDP at 75 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.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 460 is better than the GeForce GTX 660.
