AMD Radeon R9 390 technical specs and benchmarks

AMD Radeon R9 390

Summary

AMD started Radeon R9 390 sales 18 June 2015 at a recommended price of 329 USD. This is a high-end GCN 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at gamers. of GDDR5 memory clocked at 1000 GHz are supplied, and together with 512 Bit memory interface this creates a bandwidth of 384 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 275 mm. An additional 1 power connector 6-pin and 1 power connector 8-pin are required, and power consumption is at 275 Watt.

It provides good gaming and benchmark performance at 52.49 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.
