Starting with Crysis 3, the Radeon R9 390X is just 5% faster than the R9 390 but 15% faster than the R9 290X when comparing the 2560x1600 results. The R9 390X was also just 3% or 1fps slower than the GTX 980. While the R9 390 was 5% slower than the R9 390X, it was 9% faster than the R9 290 and GTX 970.
The R9 380 matched the performance of the R9 280X in Crysis 3 at 1080p, making it 8% faster than the R9 285 and 5% faster than the GTX 960.
Again we see that the R9 390X is just 5% faster than the R9 390, this time when testing with Battlefield Hardline. This meant that the R9 390X was just 7% faster than the R9 290X and 5% slower than the GTX 980. The R9 390 on the other hand was 13% faster than the R9 290 and 7% faster than the GTX 970.
The R9 380 delivered an average of 60fps at 1080p and despite that it was a whopping 14% slower than the R9 280X and just 2% faster than the R9 285. Moreover, it was 6% slower than the GTX 960.
