Radeon R7 7890K Game Requirement Analysis
Radeon R7 7890K is an integrated Graphics Card in the APU A10-7890K.
It is based on the Graphics Core Next Architecture and offers 512 Shader Processing Units, 32 TMUs and 8 ROPs. 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 1067MHz.
The Graphics Card also shares the processor's L2 Cache of 4MB, reducing the impact of its low memory bandwidth.
Overall, the Graphics Card's performance depends a lot on the system configuration. Best case scenario, expect performance superior to Intel's powerful Iris Pro Graphics 5200 and almost similar to the dedicated Radeon HD 7750.
The card is thus suited for 720p gaming and most modern demanding games can be played at least on medium settings.
