We had a world exclusive with the first Radeon R9 390X spotted thanks to PowerColor, but now details have leaked on the ASUS Radeon R9 390X DirectCU II OC. The ASUS variant will feature 8GB of GDDR5 RAM, which is in line with our exclusive story on the Fiji XT-based Fury X and Fury featuring HBM, while the 300 series cards will be powered by GDDR5.

The details leaked tease that the ASUS Radeon R9 390X DirectCU II OC will feature 8GB of GDDR5, 1070MHz Core, 6GHz on the 8GB of VRAM spread on a 512-bit memory bus. Connectivity wise, we'll have one DisplayPort, one HDMI, and two DVI-D. The ASUS Radeon R9 390X DirectCU II OC will sport 2816 stream processors, 176 texture mapping units (TMU) and 64 ROPs.

The 8GB of RAM being clocked at 6GHz is a change from the 5GHz on the R9 290X, so that's most likely what we can expect from the other Radeon R9 390X cards when they launch. ASUS has two 8-pin PCIe connectors on the card, and an estimated price of around $449 when it launches later this year.
