Iris Plus 640 vs Radeon RX 460 comparison

In our benchmarks, the Radeon RX 460 beats the Iris Plus 640 in gaming performance.

In our comparison, the Radeon RX 460 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 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.

As stated by the manufacturer, the Radeon RX 460 has significantly more memory with 4 GiB of memory compared to 0.5 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Iris Plus 640 has a significantly lower TDP at 15 W when compared to the Radeon RX 460 at 75 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 460 over the Iris Plus 640.
