3DMark, Unigine Heaven
Let's look at a set of tests from more standard benchmarks like Unigine Heaven and the new 3DMark benchmark.
I consider these tests to be somewhat of a "best case" for all the cards in our comparison. We aren't using our frame capture system, we aren't measuring frame latency, nothing like that; I think this should give you an idea of graphics performance if each vendor had the best result for each game.
Looking at the synthetic benchmarks, we start with the classic 3DMark Fire Strike tests. The Extreme run shows a pretty reasonable performance edge from the Vega FE to the GTX 1080 of 6%, the closest gap we have seen so far. The Vega FE is even 14% faster than the GTX 1070 here. Looking at the Ultra preset, the GTX 1080 only has a 3% advantage.
Unigine Heaven continues to be a sore spot for Radeon graphics cards. With a score of 64.7 FPS, the Vega Frontier Edition is only 12% faster than the Fury X! That also leaves it 8.5% slower than the GTX 1070…
