Well, if you needed any better proof that Radeon R9 390X is in fact R9 290X rebrand, then XFX comes to the rescue.
XFX Radeon R9 390X leaked by XFX..
Apparently the best place to look for leaks is the XFX website. The Radeon R9 390X, which is in fact slightly faster R9 290X equipped with 8GB memory, can be found on their website under .. R9 290X product page.
The packaging does not tell us much about the product itself, but it is without a doubt the R9 390X with 8GB GDDR5 memory. The card comes with free Dirt Rally, it has unlocked voltage and brand new cooler with diamond-shaped texture. The cooler is equipped with 7 extended heat pipes.
In case you forgot, this is the exact same card we saw 2 months ago. well almost the same, there are no gold rings around the fans.
XFX Radeon R9 390X has four display outputs: DVI-I, DVI-D, HDMI and DisplayPort. The R9 390X is supposedly based on Hawaii silicon with 2816 Stream Cores.
