Radeon R3 6400T Game Requirement Analysis

Radeon R3 6400T is an integrated Graphics Card in the APU ​A4 Micro-6400T Quad-Core.
It is based on the Graphics Core Next Architecture and offers 128 Shader Processing Units, 8 TMUs and 4 ROPs. While the central unit is set at 300MHz, the memory bus-width will be of 64-bit, as the processor only support single channeled RAM. The memory clock runs at up to 667MHz.
The Graphics Card also shares the processor's L2 Cache of 2MB. Therefore, it reduces the need to resort to its memory bandwidth.
Therefore, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance similar to the integrated Intel HD 2500.
The card is only suited for gaming below 720p and not all modern demanding games can be played, even at least on low settings.
