                                The AMD EPYC 7453 does not have integrated graphics. The AMD A4-9120 has integrated graphics, called iGPU for short.  Specifically, the AMD A4-9120 uses the AMD Radeon R3 (Stoney Ridge) , which has 128 texture shaders  and 2 execution units. The iGPU uses the system's main memory as graphics memory and sits on the processor's die. |
