Radeon RX 640 vs Radeon RX Vega M GL comparison

For gaming, the Radeon RX Vega M GL graphics card is better than the Radeon RX 640 in our tests.

Our database shows that the Radeon RX 640 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 640 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.

In addition, the Radeon RX 640 has a slightly lower TDP at 50 W when compared to the Radeon RX Vega M GL at 65 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX Vega M GL over the Radeon RX 640.
