if 7500 series is from 1995 and 7200 vxr is from 1999 why does cisco pose 7500 as higher end ?

I am trying to find a good deal on a Cisco ROuter for BGP - my first
big time router - now I have worked at router design companies and I
just don't understand how boxes designed in 1995 - are still even
around.

Isn't the 7500 series archaic ?

I have found a 7206 straight fully tricked can be had for around
2800.00
A 7206 XVR for around 4500.00

but a heavilly loaded 7507 or 7513 is only 2600.00??

I would think that the new 3700's would blow away the old 7500's just
by moores law - but damned if I can find a comprehensive comparison -
on Ciscos web site - they don't permit comparisons of models above
7200...

yes - but the architecture and the upgrades over the years mean they are
still useful.

often 7500s are still there because some functions are not on a newer box -
FDDI, IBM channel interface and so on.

And you only need a faster box if the old one isnt fast enough.....

be careful with 7200s - there is a large range of CPU performance depending
on the processor. Also, most of the cost can end up in the port adaptors
(I/O modules).

probably an old one.

you need to remember that throughput in routers is not just about CPU
throughput - architecture and offloading into extra processors, hardware or
ASIC play a big part.

37xx are designed to replace 3600s, and are a lot faster than the equivalent
3600s.

numbers off the top of my head, for fast switched packets:
3640 ~ 40k pps, 3725 ~ 100k pps, 3745 ~ 220k, 720x and NPE400 ~ 400k, 720x
and NPE-G1 ~ 900k pps

With 7500s you need to specify the processor - the 7507 etc have had at
least the RSP2 / 4 / 8 / 16, and roughly double throughput for each change.
Also, the box throughput depends heavily on the types of interfaces and
whether you install VIPs (and VIPs have had their own upgrade path).

 

Here is a decent starting point:
