Radeon RX 460 vs Radeon RX 6800M comparison

In our benchmarks, the Radeon RX 6800M beats the Radeon RX 460 in gaming performance.

The Radeon RX 6800M has a significantly 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 6800M 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6800M has significantly more memory with 12 GiB of memory compared to 4 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 Radeon RX 6800M at 145 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 conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6800M over the Radeon RX 460.
