Thanks to a few members of the site and YouTube comments pointing out this one, it seems Teclast have quietly downgraded the Atom Bay Trail in the X98 Air 3G from the Atom Z3736F 2.16 Ghz to the Atom Z3735F 1.83Ghz. There has been no official word from Teclast on this change on Weibo or Teclast.com. My guess is they have simply run out of Z3736F tray’s and have switched to using their remaining Z3735F stock. GPS is also lost it seems with comments on Banggood.com’s X98 Air 3G listing that it no longer supports GPS.
Edit: GearBest still sell the Z3736F model for now, but it’s $199 and the Z3735F model is $179, $20 cheaper.
To me this signals the last of the Bay Trail’s once Teclast use up all the Bay Trail stock, they will switch over to just making the Cherry Trail line? Intel plants aren’t making the Bay Trail Atom anymore, unless Teclast have huge amounts of Z3735F stock around. So the X98 Plus, X98 Pro, X16 Pro and X16 Power will be their Atom line up going into 2016.
