The AMD RX 6700 is the objective winner of this comparison, securing nine spec victories compared to the two held by the AMD RX 6600. The most significant advantage for the RX 6700 is its memory bandwidth, which is 43% higher than that of its counterpart. While the RX 6600 offers a 25% better TDP, the superior memory throughput of the RX 6700 makes it the more capable component across the majority of measured technical specifications.

Users prioritizing raw memory performance should select the AMD RX 6700 to take advantage of its substantial bandwidth lead. Conversely, the AMD RX 6600 is the better choice for builders who prioritize power efficiency, as its lower TDP provides a clear advantage in that specific category. Choosing between these two components depends entirely on whether your primary requirement is the increased memory capacity of the former or the improved power profile of the latter.
