What is the practical difference between these routers? Is the processor difference really significant?

The following link should be able to provide the information you are after:

http://www.cisco.com/en/US/products/ps5854/prod_models_comparison.html

It seems the 2851 supports NMD in addition to NME modules. The processor speed is also faster in the 2851.

2821 is rated at 87Mbps and 2851 is rated at 113Mbps

The 2851 provides faster packet processing as compared to the 2821

It also supports the NME-XD type modules which the 2821 wont support

Have a look at the attachment
