According to the anonymous source, this photo is taken during a closed event for the AIB partners. GTX 1660 and GTX Turing can be clearly seen in the presentation, which leads us to believe that the GTX 1660 is indeed a Turing GPU without ray tracing features.
Speculations on the technical specifications of both GTX 1660 and GTX 1660 Ti can be found on WCCFTech, but do take it with a pinch of salt for now.
The specifications listed by WCCFTech shows that the GTX 1660 might have a 3GB GDDR5 variant, which somewhat reminded us of the RTX 2060 list on Taobao earlier this month. While both will share the same 192-bit memory bus as the RTX 2060, GTX 1660 Ti is the only one that will be using GDDR6 memory.
Since ray tracing will not be the main highlight here, both GTX 1660 and GTX 1660 Ti will be using TU116-400 and TU116-300 GPU instead of the same TU106 GPU on the RTX 2060. The TU116-400 will feature 1536 CUDA cores, 1500MHz base clock with 1770 boost clock, while the lower-end TU116-300 will feature 1280 CUDA cores, 1530MHz base clock and 1785MHz boost clock.
WCCFTech also mentioned that the GTX 1660 Ti should be priced around $279 and will probably perform more or less the same as a GTX 1070.
Update: The Actual Source of the Photo?
The photo was found on TW Bahamut forum yesterday, posted by user crossxxx. In the post, he mentioned that the GTX 1660 and GTX 1660 Ti was actually announced in a closed event – NCC China? The GTX 1660 Ti will be available in February at the price of 2399 RMB (approximately $353 USD). The price for the GTX 1060 has yet to be announced, but it’ll be available soon later in March.
The photo of the closed event was also posted by ShinChao Tou, aka uing07 on his wall just an hour ago. What we know is that the closed event was held somewhere in China with the AIB partners.
