I'm curious why Cisco hasn't referred you to
http://www.cisco.com/warp/public/765/tools/quickreference/routerperformance.pdf
which includes apparently all routers from 800 series up to CRS-1.

2821: 170 kpps
2851: 220 kpps
3825: 350 kpps
3845: 500 kpps

According to that Cisco document, yes. They calculated 87 Mbps with
64-byte packets, but based on pps numbers with no features.
Unfortunately, they don't mention process switching performance for
theses models, which you could use for a worst case
router-under-attack scenario.

The same document states 353 kpps for NPE-300, which would make 3825
as good as one performance-wise.
