Not necessarily - one needs to be familiar with the hardware specs on the
particular Cisco platform one is using. It's possible to 2:1 or 4:1
oversubscribe the 10GbE ports on each linecard in a 6500/7600 series if you
configure it a certain way. Legacy 6500 stuff is 8Gbps per slot but you can
have a 16-port GBIC linecard. Or encounter a setup like a 48-port 1000BaseT
card that is on a 32Gbps backplane bus. Other things like a 7206VXR with
NPE-G1 and PA-GE modules can do line-rate GbE on the three routing engine
GBICs, but each PA-GE is more like a 600 Mbps interface.

Same with Juniper on many platforms. When using a mature platform they're
usually on the 3rd, 4th or 5th generation of linecards and supervisors that
mate with a particular chassis and backplane. It's very useful to do some
research into the technical specs and limitations of the 1st/2nd
generations to learn how the platform evolved into its current mature state.
