RTX A4000 vs Radeon RX 7900 XT comparison

According to the hardwareDB Benchmark, the Radeon RX 7900 XT GPU is faster than the RTX A4000 in gaming.

In our comparison, the Radeon RX 7900 XT 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 7900 XT 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 Radeon RX 7900 XT has slightly more memory with 20 GiB of memory compared to 16 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the RTX A4000 has a significantly lower TDP at 140 W when compared to the Radeon RX 7900 XT at 315 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 7900 XT is faster than the RTX A4000.
