AMD Radeon RX 460 Review: Polaris On A Budget

RX 460 Test System, Heaven v4.0 And Fire Strike

How We Configured Our Test Systems: We tested the graphics cards in this article on a Gigabyte X99 Gaming 5P motherboard powered by an Intel Core i7-5960X octal-core processor and 16GB of Corsair DDR4 RAM. The first thing we did when configuring the test system was enter the UEFI and set all values to their "high performance" settings and disable any integrated peripherals that wouldn't be put to use. The memory's X.M.P. profile was enabled to ensure optimal memory performance and the solid state drive was then formatted and Windows 10 Professional x64 was installed and fully updated. When the Windows installation was complete, we installed all of the drivers, games, and benchmark tools necessary to complete our tests.

Unigine Heaven v4.0 Benchmark
Pseudo-DirectX 11 Gaming

Unigine's Heaven Benchmark v4.0 is built around the Unigine game engine. Unigine is a cross-platform, real-time 3D engine, with support for DirectX 9, DirectX 10, DirectX 11 and OpenGL. The Heaven benchmark -- when run in DX11 mode -- makes comprehensive use of tessellation technology and advanced SSAO (screen-space ambient occlusion). It also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering.

The Radeon RX 460 trailed the other cards we tested in the Unigine Heaven benchmark, with the settings we used. The GTX 950 was roughly 22% faster here.

Futuremark 3DMark Fire Strike
Synthetic DirectX Gaming
3DMark Fire Strike has multiple benchmark modes: Normal mode runs at 1920x1080, Extreme mode targets 2560x1440, and Ultra mode runs at a 4K resolution. GPU target frame buffer utilization for normal mode is 1GB and the benchmark uses tessellation, ambient occlusion, volume illumination, and a medium-quality depth of field filter. The more taxing Extreme mode targets 1.5GB of frame buffer memory and increases detail levels across the board. Ultra mode is explicitly designed for high-end and CrossFire / SLI systems. GT 1 focuses on geometry and illumination, with over 100 shadow casting spot lights, 140 non-shadow casting point lights, and 3.9 million vertices calculated for tessellation per frame. And 80 million pixels are processed per frame. GT2 emphasizes particles and GPU simulations.

The Radeon RX 460 put up better scores than the GeForce GTX 960 and 950 in 3DMark Fire Strike, but the individual results are more interesting than the overall scores. The RX 460 trails in GT1, but finishes somewhat ahead in GT2. And due to the algo Futuremark uses to calculate the final score, the RX 460 ends up with the better end result.
