JavaFX versus AWT/Swing Hardware Acceleration

 What is the difference between hardware acceleration in JavaFX versus Swing/AWT? I heard a while back someone claim that Swing/AWT could never fully leverage hardware acceleration. However there are the usual mix of -D parameters (sun.java2.opengl/sun.java2d.d3d, etc.) for Swing/AWT. So I am just wondering how JavaFX’s acceleration differs from the hardware acceleration in Swing. When I was giving a talk at a JUG meeting someone called me out on the hardware acceleration bit and I realized I didn’t fully understand the differences between the two.

 I understand that JavaFX has a scene graph and Swing doesn’t etc. So I am assuming that the scene graph operations are optimized on the GPU whereas if you were trying to replicate a scene graph in Swing you would obviously be doing all the work on the CPU. So Swing’s hardware acceleration is more about buffers?

 I did come across this article:
 Specifically this line caught my attention "Prism finally renders effects with full hardware acceleration and without the extra buffer copies that spoil effects on the Swing toolkit.” 
 This article is a dated - brings up a second question about hardware acceleration with a hybrid Swing/JavaFX application - what happens?
