Radeon RX 640 vs GeForce GT 730 comparison

In our benchmarks, the Radeon RX 640 beats the GeForce GT 730 in gaming performance.

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. 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 640 has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GT 730 has a slightly lower TDP at 49 W when compared to the Radeon RX 640 at 50 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 640 is faster than the GeForce GT 730.
