GeForce RTX 2080 Ti vs Radeon RX 640 comparison

According to the hardwareDB Benchmark, the GeForce RTX 2080 Ti GPU is faster than the Radeon RX 640 in gaming.

Our database shows that the GeForce RTX 2080 Ti 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 GeForce RTX 2080 Ti 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.

Next up, in terms of GPU memory, the GeForce RTX 2080 Ti has significantly more memory with 11 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 GeForce RTX 2080 Ti at 250 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 GeForce RTX 2080 Ti is faster than the Radeon RX 640.
