Router Positioning and Rate question

Hi All

This is a bit off topic . But I think its very relevant to what we do daily
:

If we go through any router data-sheet . For example data sheet of Cisco
1900 series :

http://www.cisco.com/en/US/prod/collateral/routers/ps10538/data_sheet_c78_556319.html

It says the following :
The Cisco 1900 Series enables deployment in high speed WAN environments with
concurrent services enabled up to 25 Mbps.

What I get from this statement is :

1900 (GE) -----------------(GE) Lets say 7600

1) If we enable all services (like NAT , QoS , Security , Routing etc etc )
; we will be able to send 25 Mbps of data on the link (bidectional) .
AND
2) We will have nominal CPU utilization

Are the above 2 points correct ?

My next question is :

Since the on-board port is a Gbps port ; I believe that with no services
enabled ( just IP routing ) ; we should be able to send 1 Gbps data
bidirectionally . Am not sure what will be CPU in the case we are sending 1
Gbps bidirectionally ..... But is this assumption correct .

Please respond

Regards
Happy .
