The full specifications of the Sapphire RX 470 OC 4GB are listed below.

For comparison, the RX 480 has 36 Compute Units and 2304 Stream Processors and the same 256bit Memory interface also drawing over 150W. This comparison is worth keeping in mind when looking at the test results.

Physical Appearance & Build Quality

The Sapphire RX 470 OC 4GB card looks like a snazzy version of a stock AMD GPU. It has the same style shroud and cooler but the shroud looks more attractive with the silver finish, the hero of the card is the back plate. The back plate will help dissipate heat and help protect the PCB from clumsy actions when installing it.

As this is our first Sapphire card, we don’t have any hands-on experience with the brand or previous product experience to influence our expectation of build quality. The card itself didn’t show any signs of bending or misalignment, the cooler remained quiet and didn’t have any clicking, ticking or whine as far as the fan went. There was some coil whine at high FPS in menus etc but this wasn’t any worse than the AMD stock RX 480. 

The review period was extended to almost 3 months for this card where we ran it almost every day and stressed it with benchmarks and games. We also moved it between 3 different systems. At the end of our testing, the Sapphire RX 470 OC 4GB didn’t show anything that indicated a compromise in the build quality.
