Saku, Jericho is in no sense a low end chip, while there are some scale limitations (what can be done with SuperFEC, some bridging related stuff), from functionality prospective it is a very capable silicon. One has to: Understand how to program it properly (recursiveness, ECMP’s, etc) Know how to enhance SDK Have a rather rich control plane, which can be translated into rich forwarding functionality :-) I’m not familiar with Arista’s feature set NCS with XR would be a good proof Watch for Jericho updates from DNX Cheers, Jeff On 4/23/16, 11:20 AM, "NANOG on behalf of Saku Ytti" <nanog-bounces@nanog.org on behalf of saku@ytti.fi> wrote:

In broad strokes: for your money you're either getting port density, or more features per port. The only difference here is that there's suddenly more TCAM on the device, and I still don't see the above changing too drastically.
Yeah OP is comparing high touch chip (MX104) to low touch chip (Jericho) that is not fair comparison. And cost is what customer is willing to pay, regardless of sticker on the box. No one will pay significant mark-up for another sticker, I've never seen in RFP significant differences in comparable products.
Fairer comparison would be QFX10k, instead of MX104. QFX10k is AFAIK only product in this segment which is not using Jericho. If this is competitive advantage or risk, jury is still out, I lean towards competitive advantage, mainly due to its memory design.
