Sapphire RX 6600 XT Pulse Review

For our manual overclocking tests, we used AMD's built-in tuning tool. Our best results are as below.

Overclocking the Sapphire Pulse gave slightly better results than the Gaming OC Pro. We were able to push the GPU core up to 2990MHz (!), with the memory set to 2300MHz.

That resulted in a real-world operating frequency of 2933MHz, about 130MHz better than what we could manage with the Gaming OC Pro.

This overclock resulted in gains of between 9-11%, so that is a slightly better relative gain compared to the Gaming Pro OC, but we do also have to stress this can vary from sample to sample. Still, it is good to see you can squeeze a bit more out of this chip, even if the days of an extra 20% boost to your frame rates are long gone.

Power draw rose a fair amount when overclocked, up to 188.1W at 1080p. That's a 19% increase over stock.
