It mostly depends on what the device is used for.
Looking purely at specs the older one is slightly faster just looking at the GHz values, but the newer one has twice as much cores (2 cores N2830 / 4 cores J3455)
Thanks for answering. You're giving me teorically data but, on "day by day" situations? I have a DN2820.. that is enough for me for watching Netflix, MKVs, Popcorntime... But the wifi card os very slowly and it works on 2.4 ghz band with 802.11N technology. I thought that an upgrade will do the job I was looking at.
The Celeron in the AY NUC is two generations newer than that in the FY NUC. It thus should provide a reasonable performance improvement. That said, however, there are outstanding issues with the graphics engine on the AY NUC (especially for those trying to use a 4K display) and I thus cannot recommend this upgrade until these issues have been resolved.
If you want to try improving the wireless solution in your FY NUC, I recommend trying the AC-7260. There are both first (M.1) and second (M.2) generations of this part, so make sure you choose the former (M.1).
Here is a link to the part I am talking about: Amazon.com: Intel Dual Band Wireless-AC 7260
You do not want this version: Amazon.com: Intel Dual Band Wireless-AC 7260NGW
This is a newer generation part that might also work (but I have not tried this one): Amazon.com: Intel Dual Band Wireless-AC 3160.HMWG.R
Hope this helps,

Thank you for reaching the Intel(R) Communities. I understand you would like to check if it would be good to change your unit to an Intel® NUC Kit NUC6CAYH. We can certainly check on that.
Based on the previous answer, you would like to get an improvement in terms of wireless connections.
As per the WiFi adapters on each unit, the Intel® NUC Kit NUC6CAYH would be good for that. The WiFi adapter is newer and has more capabilities than the other one.
It would also be good to have future proof with a more recent system, in terms of general updates for the system.
With that said, it would be up to your liking or preference to update the system or keep on using the one you currently have.
You can find a comparison of the WiFi adapters here: https://ark.intel.com/compare/75174,94854
If you have further questions, feel free to reach us.

I have both and the CAYH does seem slightly 'snappier' in use of the two. The biggest difference for me was the indicator light on the front of the CAYH, all my NUCs are used as HTPCs, no more standing over the NUC to see what state it is in as is the case with earlier NUCs. I have the DCCP847DYE, D54250WYK, DN2820FYKH and NUC6CAYH, all have been relatively trouble free.
