Sapphire Nitro+ RX 470 OC Graphics Card Review

Overclocking and Overclocked Performance

The revised review procedure now involves analysing the factory boost clock to determine if the quoted speed is maintained on a regular basis. Thankfully, Sapphire’s 1260MHz boost is completely stable and never fluctuates from this figure resulting in consistent performance. This is the polar opposite of the Sapphire reference model which very rarely maintains its maximum boost clock.

Overclocking the graphics card was a simple task and I managed to increase the boost clock to 1350MHz without any issues. Initially, I tried to achieve a figure around 1370MHz with a substantial voltage increase but this just wasn’t possible. Speaking of voltages, please note the highest option in Wattman was applied and the overclock didn’t involve stock or lower voltages despite the screenshot below. On another note, the memory overclocked rather well and performed well at 1795MHz.

Here we can see the screenshot comparing the factory overclock and gains from manual overclocking:

Ashes of the Singularity

Once overclocked, the graphics card managed a small frame-rate improvement which is within a margin of error.

Doom

In Doom, the performance boost was more substantial and closed the gap to the RX 480.

Just Cause 3

Rather impressively, the GPU achieved an identical average frame-rate as the RX 480 when overclocked and the minimum was slightly higher. Again, another strong showing and minor difference to the RX 480 after overclocking.
