3850 vs. 4500 10G Performance

I have been looking for performance numbers comparing the 3850 with the 4500 on 10G performance. I have heard some say the 10G performance of the 3850 is similar to that of the 4500. Any idea if there is over subscription on the 4 port 3850 interfaces?

I have heard some say the 10G performance of the 3850 is similar to that of the 4500.

No one can answer this question unless more information is provided.  

 

1.  What is the EXACT chassis model?  ("4500" is not just enough as there are different backplane speed between different models.)

2.  What is the EXACT supervisor card?

I believe none of the 3850's ports are oversubscribed, including its 4x10g.  As Leo notes, 4500 oversubscription depends on actual device; chassis, line cards and supervisors vary.

However, oversubscription is just one factor in a device's performance.  There's also frame/packet forwarding performance (believe the 3850 is wirespeed, but again, you need to select specific 4500 components for their performance attributes), and there's buffering (suspect the 3850 might be worst than some 4500 ports), and there's other feature and architecture considerations that may impact performance.

Also with a 3850, when you stack units, you have a ring, but with a 4500 you have a fabric between line cards.  I.e. another performance consideration.
