Benchmark Results: 3DMark 11 And Unigine
As usual, we kick off the benchmarks with Futuremark’s synthetic 3DMark 11. This is the only test in which we'll run all three presets, and we see the dip in performance typical of GCN-based cards at the Extreme level.
A card with these specs was never intended for this test's Extreme setting. Using more conservative options, the 768-shader Pitcairn-based sample beats Nvidia's GeForce GTX 560 Ti by a small margin. We consider that to be quite an achievement considering 3DMark 11 tends to favor Nvidia cards.
Unigine Heaven 2.5
Unigine’s Heaven 2.5 paints a similar picture, with our Pitcairn engineering sample coming in just ahead of Nvidia’s GeForce GTX 560 Ti, nearly putting it on par with a Radeon HD 6950.
In Unigine’s Sanctuary, the engineering sample can even beat out a GeForce GTX 570, although we should mention that cards based on AMD’s new GCN architecture generally do very well in this benchmark.
Meanwhile, AMD’s previous-generation cards fall to the back of the pack, even ending up behind the Radeon HD 7770. Speaking of which, the HD 7750 interestingly comes in ahead of its bigger sibling. We’ll chalk this up to a driver issue for now, and re-evaluate performance using the next driver update in the course of our normal charts revision.
