AMD Radeon R9 390 X2 technical specs and benchmarks

AMD Radeon R9 390 X2


AMD started Radeon R9 390 X2 sales 3 September 2015 at a recommended price of 1,399 USD. This is a high-end GCN 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. 2x 8 GB of GDDR5 memory clocked at 5.4 GHz are supplied, and together with 2x 512 Bit memory interface this creates a bandwidth of 2x 345.6 GB/s.

Compatibility-wise, this is 3-slot card attached via PCIe 3.0 x16 interface. An additional 4 8-pin power connectors are required, and power consumption is at 580 Watt.

It provides outstanding gaming and benchmark performance at 92.68 percent of a leader's which is NVIDIA Quadro P6000.

Compatibility, dimensions and requirements

Information on video card compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus - if the video card is inserted into the slot instead of being soldered to the notebook motherboard.
