First let's check out that what are the things which you need to check in a Ryzen processor laptop that makes it a perfect laptop for AutoCAD? 

 

The most important thing that you need to check in your laptop is CPU , GPU , RAM , storage and lastly the Full HD display which make it a perfect AutoCad laptop .But first you have to check out that which software you will use.

PROCESSOR :

For an AutoCad laptop the minimum requirement of  the cores is Quad core (4) ;
more the number of cores more the better performance.
Here the Ryzen 5 4500u processor comes with hexa core [ 6 cores and 6 threads ] .
Ryzen 7 4700u processor comes with octa core [ 8 cores and 8 threads ] if you have a slightly bigger budget  .

RAM :

8 GB of RAM  is perfect for doing basic AutoCad and 2D works but i will recommend to go for  16  GB of RAM  so that you can get a smooth experience while working on AutoCad and  3Ds Max and for also rendering 3D files faster.
 
GRAPHIC CARD :
 
The Ryzen processors laptops comes with AMD Radeon Vega graphics which is good for doing the Autodesk work easily and flawlessly but if you want to run heavy software like CAD or 3Ds max then you need a dedicated graphic card of at least 2GB or upto 4GB cause it helps to render the  files faster with a good visual graphics .
 
Here is the video of AutoCad running in Ryzen 5 3500U laptop
 

STORAGE :
 
If the laptop which you will choose comes with the dual storage type then its good, but if you get a single storage type then I recommend you to go with the SSD drive because SSD works faster than HDD . 
 
So these are the things you need to check before you buy a laptop for AutoCad.
