Radeon RX 6800M vs Radeon RX 6600M comparison

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

In our comparison, the Radeon RX 6800M 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. In addition, the Radeon RX 6800M also 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.

As stated by the manufacturer, the Radeon RX 6800M has significantly more memory with 12 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 significantly lower TDP at 100 W when compared to the Radeon RX 6800M at 145 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6800M is better than the Radeon RX 6600M.
