Rating: 9.0.

We supplement our analysis of AMD partner RX 480 cards today by looking at the two Sapphire Nitro+ OC models, in 4GB and 8GB capacities. The Sapphire cards ship with custom cooling solutions, out of the box clock enhancements, LED lighting and PCB improvements. At price points of £199.99 and £249.95 inc vat for the 4GB and 8GB cards respectively, they certainly look to be competitively priced.

The new AMD Radeon RX 480 is built on the FinFET 14nm process. For Polaris, AMD selected Samsung and Global Foundries 14nm FinFET based process technology, the densest foundry process available. FinFET transistors are crucial to reduce power consumption while enabling operating voltages which are 150mV lower than the previous generation.

We can’t really comprehend how Sapphire ended up with 1,306mhz and 1,342mhz for the core clocks of the 4GB and 8GB cards respectively, they must have been throwing darts at a board. Memory speeds of the GDDR5 on the 4GB model are clocked down, from 2,000 mhz (8Gbps effective) to 1,750 mhz (7 Gbps effective). The 4GB version ships with Hynix GDDR5 memory, the 8GB version Samsung GDDR5 memory.

Additionally the cards have a dual BIOS with ‘quiet’ or ‘boost’ mode.

Quiet mode downclocks the core on both cards to 1,266mhz, further reducing fan noise. We test both cards today in the fully fledged, fast mode, as we do with all the samples we receive. I believe that the overwhelming majority of KitGuru readers will want to game with the card running at full speed.
