Some of the first pictures of XFX' Radeon R9 390 Double Dissipation graphics card made it to the web, weeks ahead of its launch. The card features a tall dual-slot cooling solution, featuring two 100 mm spinners, ventilating a large aluminium fin-stack heatsink. The card draws power from a combination of 6-pin and 8-pin PCIe power connectors. It features bridge-less XDMA CrossFire, much like the R9 290 series.

The second-best SKU carved out of the "Bermuda" silicon, the R9 390 will be positioned a notch below the R9 390X. There's no word on its specs, or how AMD carved it out of the "Bermuda" silicon, which features 4,096 stream processors based on the latest version of the Graphics CoreNext architecture, and a 4096-bit HBM memory interface, churning out 640 GB/s of memory bandwidth. AMD could allow its partners to come up with custom-design cards from day-one, with memory amounts ranging between 4 GB and 8 GB. The R9 390X and the R9 390 will be competitive with NVIDIA's GeForce GTX TITAN X, and other upcoming cards based on the GM200 silicon, such as the GTX 990.
