AMD Radeon R9 M390X: specs and benchmarks

VS

Summary

AMD started Radeon R9 M390X sales 9 June 2015. This is a laptop graphics card based on a GCN 3 architecture and made with 28 nm manufacturing process. It is primarily aimed at gamers. 4 GB of GDDR5 memory clocked at are supplied, and together with 256 Bit memory interface this creates a bandwidth of 160.0 GB/s.

Compatibility-wise, this is card attached via PCIe 3.0 x16 interface. Power consumption is at 100 Watt.

It provides poor gaming and benchmark performance at 8.63% of a leader's which is NVIDIA GeForce RTX 4090.

Benchmark performance

Synthetic benchmark performance of Radeon R9 M390X. The combined score is measured on a 0-100 point scale.


Combined synthetic benchmark score

This is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.

Passmark

This is the most ubiquitous GPU benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.

Benchmark coverage: 25%

3DMark 11 Performance GPU

3DMark 11 is an obsolete DirectX 11 benchmark by Futuremark. It used four tests based on two scenes, one being few submarines exploring the submerged wreck of a sunken ship, the other is an abandoned temple deep in the jungle. All the tests are heavy with volumetric lighting and tessellation, and despite being done in 1280x720 resolution, are relatively taxing. Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy.
