PowerColor Red Devil Radeon RX 580 Video Card Review

Fire Strike is a new DirectX 11 showcase benchmark designed for high-performance gaming PCs.  The benchmark features real-time graphics rendered with detail and complexity far beyond what is found in other benchmarks.  Fire Strike Ultra takes things a step further by running at 4K resolutions.

Fire Strike Ultra can simulate 4K and scale the output to whatever resolution you have available making the testing of that resolution available to those limited to sub-4k resolutions.  Of course success with 4K comes down to frame buffer and memory bandwidth.
