AMD Radeon R9 390 X2: 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. This is GCN 2.0 architecture desktop card based on 28 nm manufacturing process and primarily aimed at office use. 8 GB of GDDR5 memory clocked at 5.4 GHz are supplied, and together with 512 Bit memory interface this creates a bandwidth of 345.6 GB/s.

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

It provides poor gaming and benchmark performance at 0.03 percent of a leader's which is NVIDIA GeForce RTX 2080 Ti.
