In Europe no Exynos it's always the SnapDragon, I thought Exynos was for the US, so I got a Qualcomm chip.
E18 rev B : differences are here
I had the 2013 IE800 before returning it, too bright on some tracks or imaging issues, my SE846 were manufactured on 11/14/2013 BTW
I am fairly certain that the only reason Samsung uses the Snapdragon 800 is because of the LTE radio used in U.S. variants. I think Samsung uses its own Exynos processor in most other situations. If you have model number N9000 then you have the Exynos (and probably a different DAC than I have--maybe that Wolfson). I wish mine was warmer than the iPod.
Oh, and some head-fier mentioned that the Dragonfly only worked with the Note 3's default music app. I didn't know until then. It had a lot of static using Poweramp and I thought it was incompatible, but it works fine with the default app. It doesn't sound all that good though and it burns thru the Note 3's battery in 5 hours (or less).
