The list of leaked GTX 1660 graphics cards include ones from EVGA, Gigabyte, and MSI confirming earlier rumors that it should still be based on the 12nm Turing TU116 GPU but with 1408 CUDA cores as well as come with 6GB of GDDR5 memory on a 192-bit memory interface.
Such specifications will allow Nvidia to differentiate it from the GTX 1660 Ti which has 1536 CUDA cores and a much faster GDDR6 memory. This also means that the GTX 1660 will be significantly cheaper than the $279-priced GTX 1660 Ti, launching at $219.
The GPU base and Boost clocks will vary depending on the version but the reference clocks should be set at 1530MHz base and 1785MHz GPU Boost clocks, while some OC versions could go as high as 1860MHz.
Videocardz.com posted several of these GTX 1660 graphics cards including three from MSI, two from EVGA, and two Gigabyte versions. Most of these graphics cards will draw power from a single 8-pin PCIe power connector, and there will be plenty of different versions, ranging from standard ones to Gaming and OC versions with dual- and even triple-fan cooling solutions.
On a similar note, Nvidia is also expected to launch the GTX 1650 graphics card, which should be coming in late-April with TU117 GPU, 4GB of GDDR5 memory on a 128-bit memory and a suggested price of $179.
