It is rumored that AMD is working hard on releasing the next high-end graphics cards, tagged as Radeon R9 390X (or 380X). Asian website Chiphell now has posted a couple of benchmarks in their forums 'showing' these graphics cards in terms of performance.

We think the result tagged as "Captain Jack" could be the Radeon R9 390X (we think) and not 380X, though that remains to be a VERY wild guess. Performance wise it is looking pretty good TBH, however the results should be taken with a HUGE massive grain of salt as there is no validity whatsoever of these results being the true thing let alone indicating what card it precisely is.

So look above, at Chiphell a user posted two charts, the first (upper) chart shows average performance from several gaming titles such as Assassins Creed: Unity, Dragon Age: Inquisition, Alien Isolation and Metro Last Light Redux. it is a horribel way of normalizing a chart, but hey at the very least it is indicative of something. As you can see, the games were tested across a wide range of graphics cards from NVIDIA and AMD at 2560×1440 resolution with IQ settings set to maximum. The test setup includes a Intel Core i7-4790 clocked at 3.60 GHz and the drivers used were 344.75 WHQL for NVIDIA cards and Catalyst 14.11.1 BETA for AMD cards. 

The second chart as shown above shows relative load (stress) power consumption, at just undfer 200 Watts. Anyway, we post it as we see them, make of this whatever you want.
