Radeon R7 240 vs Radeon RX 640 benchmarks

In our benchmarks, the Radeon RX 640 beats the Radeon R7 240 in gaming performance.

Our database shows that the Radeon RX 640 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. In addition, the Radeon RX 640 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the Radeon RX 640 has significantly more memory with 4 GiB of memory compared to 2 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon R7 240 has a significantly lower TDP at 30 W when compared to the Radeon RX 640 at 50 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 Radeon RX 640 is faster than the Radeon R7 240.
