This is rumor, but so far all of videocardz rumors have been correct for 2019. 
NVIDIA Is indeed planning to launch another GTX Turing graphics card called GTX 1650. So far there is no confirmation on GTX 1660 non-Ti, but according to 3rd party recent leaks, that card is surely happening at some point. This also confirms that GeForce GTX Turing series are basically called 16-series. The card is likely to feature smaller Turing GPU, presumably TU117. Apart from that, not much is known about the card. We have, however, heard it launches next month. Earlier rumors indicated that GeForce GTX 1650 was planned for ‘late’ March, which may still hold true.

which makes me tend to believe ampere is not far behind
 
xx50 series cards are usually released near the end of that series line
 
and with 12nm officially dead becuase of tsmc woes - id say 7 nm is incoming sooon

They are not going to call any cards they release 1650's or 1660's etc.... so stupid. Nvidia is going to release new cards of course but they are going to be the rest of the lower end of the 2xxx line like 2050, 2040, 2030, etc ..... These guys over there, videocardz, know this and they know whats going to get dropped but instead they turn out this rumor bait crap to get some clicks and it annoys the crap outta me.

So 1660 Ti was announced today

Also, EVGA renamed a forum section. "EVGA GeForce 20/16 Series"

Yep that is correct. NVIDIA sales of RTX cards haven't been as good as they would have liked so cheaper mid-range cards might help them financially. These cards simply don't have ray tracing and DLSS capability.

RTX and DLSS are the most problematic and controversial features of the cards. Having lower cost "standard" alternatives is a really good idea.

So what is the GeForce 2016 Series? Is that what they're renaming the Pascal cards? Ha-ha

No, no. You missed the slash. 20/16

20xx / 16xx

You know... slash ... like "and"...

Lol, ok, I was wrong and they actually went against all there history and any sense.  I still think its a very stupid naming scheme. Why they weren't just GTX2050ti and GTX2050 is beyond me unless they plan on putting out two more under those monikers to further confuse and squeeze the market. Yes, I saw what the nvidia rep said on why they named it the way they did and still don't buy that's the whole story. Anyway, let the tomatoes fly!!!
