According to leaked Gigabyte documents, the upcoming AMD Zen 4 Ryzen desktop CPUs will offer integrated graphics. While this does not mean that literally all CPUs will have iGPUs enabled, it does confirm that the mainstream Zen 4 silicon will be paired with graphics for the first time. Thus, the GPU will no longer be exclusive to the Ryzen G-Series APUs.
According to latest rumors, AMD is planning to release their Zen 4 5nm desktop processors in early 2022. AMD Zen 4 could be Ryzen 7000 series, codename “Raphael”. It will feature with 5nm and Navi2 graphics.
