Radeon RX 6800 vs Radeon RX 6600 comparison

According to the hardwareDB Benchmark, the Radeon RX 6800 GPU is faster than the Radeon RX 6600 in gaming.

Our database shows that the Radeon RX 6800 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. Despite this, the Radeon RX 6600 has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6800 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 6600 has a significantly lower TDP at 132 W when compared to the Radeon RX 6800 at 250 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 6800 over the Radeon RX 6600.
