Sapphire R9 270 Dual-X 2GB Graphics Card Review

Overclocking

The Sapphire R9 270 Dual-X we had was a below-average overclocker in my opinion. I’ve actually read reviews of this graphics cards on other sites where I’ve seen 1045-1055MHz achieved on the core and 1485-1600MHz achieved on the memory. Ours wasn’t really able to match that on the core with a rather below-average 1030MHz, but on the memory it did well posting 1525MHz memory. For comparison the ASUS R9 270 DC2 OC graphics card we reviewed managed to achieve 1154MHz on the core and 1520MHz on the memory.

The final overclock didn’t see it gain that much performance – only 6.5%, up from P7708 to P8188. It is a nice boost but other cards will do better. I can’t really be too hard on the Sapphire graphics card though because it’s the the silicon lottery that determines the maximum overclock.
