Radeon RX 460 vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6400 GPU is faster than the Radeon RX 460 in gaming.

Our database shows that the Radeon RX 6400 has a significantly 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. In addition, the Radeon RX 6400 also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Next up, in terms of GPU memory, they both have the same amount of memory at 4 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 RX 6400 has a slightly lower TDP at 53 W when compared to the Radeon RX 460 at 75 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6400 is faster than the Radeon RX 460.
