Does Ryzen 5 work and what would be the min for AMD graphics card. 

The graphics in the Ryzen apus are really only capable for building schedules. Unless you are projecting at extremely low resolutions, they aren't a viable option. 

Officially there are no supported AMD graphics according to EW support. That said any AMD graphics card with a score or 13,000 or higher that has enough outputs for your needs should work fine. The current Radion RX 9060 XT, 9070, and 9070 xt should work just fine. If you can still find them, RX 6650, 6700, 7600, 7700, 7800, and 7900 models will also work just fine, just not officially.  

With the way that Nvidia is overcharging, lowering the quality of their cards, and forcing a defective and highly dangerous power cable design on their newer cards I'm hoping that EW get's their act together and starts supporting the more than capable as well as more affordable AMD cards officially. They used to recommend AMD cards (labeled as ATI cards back then) when EW2009 was being sold, but due to an issue with a piece of software that was added to the drivers that caused some issues with EW they stopped supporting or recommending them. ATI/AMD removed that software from their drivers at least 10 years ago, but EW hasn't changed their support stance on AMD cards.

My church and I have had MUCH better reliability and performance from ATI/AMD cards than Nvidia cards over the past 12 years and we are about to replace the Nvidia card that EW support recommended with an AMD card.
