Radeon R5 7100 Game Requirement Analysis

Radeon R5 7100 is an integrated Graphics Card in the APU A8-7100.

It is based on the Graphics Core Next Architecture and offers 256 Shader Processing Units, 16 TMUs and 8 ROPs. While the central unit is set at 514MHz, the memory bus-width will depend on whether or not the system's RAM is dual-channeled and the operating memory clock, on its frequency. Thus, it can be either 64-bit or 128-bit and up to 800MHz.
The Graphics Card also shares the processor's L2 Cache of 4MB. Therefore, it reduces the need to resort to its memory bandwidth.

Overall, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance similar to a dedicated NVIDIA GeForce 710M or an AMD Radeon R5 M220.
The card is only suited for gaming below 720p and all modern demanding games can be played at least on low settings.
