We wouldn't recommend you overclock a passively cooled card, as the tolerances can often be close to borderline, especially if you are installing into a chassis with poor airflow. For the purposes of this review however we used the AMD Catalyst Control center to overclock the Sapphire R7 250 Ultimate today.
Considering the passive nature of the hardware, we managed to achieve a decent 6.3% overclock on the core before artifacting would occur. Memory could be overclocked to the maximum range of the Catalyst Control Center slider – hitting 1,250mhz (5Gbps effective).
The additional overclock helps improve the graphics score in this benchmark to 3,282 points.
no single slot? well that sucks… HTPC users need single slot cards.
Harris, AMD cards output a lot of heat, building this into a single cooler design would be not feasible, based on the temperature results Kitguru recorded.
AMD need the Maxwell architecture for this. I am surprised Nvidia haven’t released a single slot passively cooled MAXWELL based card, but I am sure it is coming soon.
Including the previous Sapphire Ultimate (HD 7750) in the test comparisons would have be very helpful. Next time?
