Radeon RX 640 vs Radeon RX 570 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 570 GPU is faster than the Radeon RX 640 in gaming.

In our comparison, the Radeon RX 570 has a slightly 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. Despite this, the Radeon RX 640 has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 570 has significantly more memory with 8 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 640 has a significantly lower TDP at 50 W when compared to the Radeon RX 570 at 150 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 570 over the Radeon RX 640.
