According to the performance database http://fifonik.com/nv/ the R9 280X significantly outperforms R9 290! The results show 22.7fps vs 16.4fps with radius "1", and 43.5 fps vs 27.8 with radius "0" in 1080p mode.
How can this be possible? Anyone can confirm that?
Does R9 280X really outperforms R9 290?
You can check the original logs in that database. There also references to the forum members who measured those data.
According to the logs, 280X is faster than 290 when both its chips are used. However, each individual chip of 280X is slower than 290. So it looks like 280X is only faster because both its chips are used together.
