Check AM4 pinout, you will find everything integrated. pcie, ram, usb 3.0, sata, HD Audio, RTC/SPI/I2C/SMBus and LPC are all on die.

AMD own AM5 test rig is also chipsetless https://youtu.be/7H4eg2jOvVw?t=615 https://youtu.be/7H4eg2jOvVw?t=615. Straight from AMD Core Design dude mouth https://youtu.be/7H4eg2jOvVw?t=797 https://youtu.be/7H4eg2jOvVw?t=797 and at 23:00 there is whole segment about test lab running those boards without any "chipsets".

  That is a good video! In fact, that video (which I saw previously here on HN) is the one that gives rise to the set of ideas which led to the search which led to my post. Remember, I said "show me [a] commercially shipping PC motherboard with no additional support chips/IC's" I want what AMD has in their lab -- to be commercially available. Also -- if I were designing things, if I think about it, I'd design a CPU that had any slower-speed functionality (i.e., integrated sound chip) off of it, and all of that functionality could be handled by a second user-replaceable/user-programmable/plug-and-play FPGA, or multiple FPGA's or multiple modular chip sockets... Basically, bring back Southbridge -- but make everything it connects to, including the Southbridge chip itself -- modular and easily user replaceable... that is, each chip is not soldered directly to the motherboard, but instead has the appropriate plug-and-play socket for easy removal/replacement... I'm just thinking aloud here... I am not a professional CPU designer -- but that's how I would do things if they were up to me. Anyway, excellent links!

I don't question that AMD CPU's as of AM4 generation sockets may have all of this -- but the boards in the pictures still have additional black silicon support chips/IC's on them... What are all of those other chips for?
