With the new Radeon R9 280X TurboDuo OC, PowerColor introduce its first graphics card equiped with their new TurboDuo cooling system. An efficient and silent solution on the paper according to the manufacturer. Other than that the card features a reference Radeon HD 7970 PCB and a slight factory overclocking. Let's see what it can do.

Presentation

The new Radeon R9 280X TurboDuo OC graphics card from PowerColor features a reference design PCB, TurboDuo cooler and a tiny factory overclocking. Overall it is PowerColors interpretation of a non-reference Radeon R9 280X graphics card.

Since it is the TurboDuo OC version of the PowerColor Radeon R9 280X series, the card features a slight factory overclock of 30 MHz on the core. While the standard reference Radeon R9 280X GPU is set to work at 850 MHz for the base clock and 1'000 MHz for the Boost clock, the PowerColor TurboDuo OC works at 880 MHz for the base clock and 1'030 MHz for the Boost clock.

Unfortunately, no factory overclocking was done on the 3GB of GDDR5 memory that remains at the recommended 1'500 MHz (6'000 MHz effective).

During our testing the PowerColor Radeon R9 280X TurboDuo OC held 1'030 MHz most of the load time. We have only experienced downclocking under FurMark where the GPU clock was going up and down from 1'030 MHz (1.150v) to 880 MHz (1.050v) past 70°C. We didn't notice any throttling while gaming.
