PowerColor PCS+ HD7870 Gaming Video Card

Benchmarks

 

A foreword before I get on to the test results. Since the card came overclocked, and I wasn’t a fan of the noise, pardon the pun, I decided to turn the GPU clock and the Memory clock down by 125MHz and 535MHz, resulting in 800MHz and 965MHz respectively. The first slew of tests were performed at this output (from this point on referred to as “Comfortable Settings”), while the second were performed on it at default speeds.

As you can see from the results of these benchmarks, the default over clocked setting is a true powerhouse, capable of sustaining high fps in stressful environments. With tessellation ticked on, performance is reduced by about ~20% but that’s not too big a deal, as the card still held a solid 56FPS average during the stress test. For the absolute stress test, I must say the the Firestrike test suite in 3DMARK was a monster. Without overclock, the card struggled to keep above 15FPS, and even while OC was enabled, the peak FPS was 27. I should mention, however, that Firestrike is meant for extremely high end graphics cards, and this result, while not optimal, in no way disqualifies this card from being a fantastic piece of hardware.
