No, CPU is still doing routing etc. Only the buses changed from simple
PCI ones to dedicated-ASIC based. The firewall (ACLs/statefull firewall)
is also software-based not hardware based. However, it's true there's
internal simple VPN ASIC on-board, that usually can serve up to 500-700
tunnels (but the AIM slot is ready for dedicated AIM module, which
if installed, enhances throughput and maximum number of the VPN
tunnels). Also, there's internal TDM functionality on-board, so You can
start mixing DS0 channels from various interface cards without any
special considerations and specific module cards.

Most of this information is already available on the cisco.com/go/isr
site, with presentations and technical specs.
