 # AM Driver
 
-AM driver is a userspace driver targeting AMD's 7900XTX. You only need tinygrad to send compute tasks to your GPU!
+AM driver is a userspace driver targeting AMD's RDNA3/RDNA4. You only need tinygrad to send compute tasks to your GPU!
 
 ## How to run?
 Make sure that amdgpu module is unloaded and just run tinygrad with `AMD=1`!
