Quadro RTX 4000 vs Radeon RX 6400 comparison

According to the hardwareDB Benchmark, the Radeon RX 6400 GPU is faster than the Quadro RTX 4000 in gaming.

In our comparison, the Radeon RX 6400 has a significantly 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 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, the Quadro RTX 4000 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 6400 has a significantly lower TDP at 53 W when compared to the Quadro RTX 4000 at 160 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6400 over the Quadro RTX 4000.
