Overclocking
The appeal of overclocking has waned alongside reduced headroom on modern parts, so it is surprising to find that entry-level Navi 23 GPUs show better willingness than most. The caveat on Radeon RX 6600 is that memory is limited to an effective 15.2Gbps.
It is possible to increase performance with very little effort, but power and memory limitations are there for a reason; AMD doesn't want RX 6600 encroaching on RX 6600 XT territory.
