The forwarding engine of the ASR 920 is a fixed (non-modular) version of the 64Gbps RSP2 used in the A900 line (902, 903, 907, etc). It will provide wire-speed forwarding for all ports of an ASR 920 with real-world packet sizes.
All ASR900/920 models require an IOS-XE license which is available in one of three levels: Metro Access, Metro IP Access, and Advanced Metro IP Access. Take a look at the A900 IOS-XE data sheet to match up your use-case requirements to the appropriate level, but briefly, Metro Access = basic L2, Metro IP Access = basic L3, while Advanced Metro IP Acess = MPLS:

The 10G license enables SFP+ ports to operate at 1G/10G rather than just at 1G, but does not license the system for XE.
