Because it is simply should not be needed (I do not play games) due to its advanced integrated video. That is what the "G" is for in 3200G (I have) and Ryzen 5 5600G and 7 5700G. Has been given good reviews, even thoughn now it is about $100 cheaper.
If you thought the AMD Ryzen 7 5700G was a great value for an 8 core/16 thread CPU from AMD, which we proved in our review, then step aside and let’s welcome a great value for a 6 core/12 thread CPU with the AMD Ryzen 5 5600G APU desktop processor. The AMD Ryzen 5 5600G is an APU based on AMD’s latest Zen 3 architecture with AMD Radeon Graphics built-in. - https://www.thefpsreview.com/2022/03/17/amd-ryzen-5-5600g-apu-performance-review/
Cheaper than the IGP-less Ryzen 5 5600X ($299 MSRP) and layered in with the highly-capable Radeon RX Vega 7 graphics engine, the AMD Ryzen 5 5600G is a serious threat to Intel's competing Intel Core i5-11600K on CPU grunt, and really puts the hammer down once you factor in its gaming results and its Radeon Software compatibility. - https://www.pcmag.com/reviews/amd-ryzen-5-5600g
My 3200G w/ 64GB Ram and m.2 NVME main drive plus 3 SSD's easily handles about 400 tabs open across 7 browsers with multitpe tab rows (hack) and many documents, thanks be to God.
