Whichever way you look at it, overclocking a Radeon RX 5700 Series GPU isn't as easy as a rival GeForce RTX. While the GeForce can be ramped-up with one click of an automated tool, the Radeon tends to require a bit more thought and care.

With Sapphire's RX 5700 Pulse some limitations become apparent. The power target is limited to +20 per cent (compared to +50 for the RX 5700 XT model), memory speed is capped to 14.9Gbps, and boost clock tops out at 1,850MHz. Setting such speeds using WattMan is hit-or-miss (we encountered a few crashes along the way), and GPU fan speed had to be fixed to a higher level in order to maintain improved speeds during the benchmarks.

With the overclock in place, our review sample averaged 1,800MHz in-game, resulting in a modest performance boost for those willing to put in the effort.
