Is 4506 + sup 4 faster than 6059 + sup 2 ???

According to spec

A 4506/4507R with sup 4 has 64G backplane, forward 48Mbps. Sup 4 has 333 MHZ CPU.

A standard 6509 with sup 2 and PFC card has 32 G backplane, 30 Mbps. Sup 2 has 300 MHZ CPU.

is a 4506 faster than a standard 6509 (no SFM)?

I know some line cards of 6500 series have DFC option.

Do 4500 line cards have similar option?

Appreciate for any thoughts, inputs, comments.

In reading the spec, it might seem that way, but a 6509 with switch fabric can push 256Mbps and the line cards support a true 100% throughput per port, not shared processors per every 8 ports in a 4500. So a 6509 will move more data per port sustained then a Cat 4000.

You also have to think about redundancy in a 6500. In Native mode if a sup fails there is no downtime to swap it, in a 4507 it will take a minute or more for the sups to swap in case of a failure.
