Radeon RX 6600M vs RTX A4000 benchmarks

For gaming, the RTX A4000 graphics card is better than the Radeon RX 6600M in our tests.

Our database shows that the Radeon RX 6600M 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 6600M also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the RTX A4000 has significantly more memory with 16 GiB of memory compared to 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6600M has a slightly lower TDP at 100 W when compared to the RTX A4000 at 140 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the RTX A4000 is faster than the Radeon RX 6600M.
