The GeForce GTX 1660 SUPER Gaming OC has the same exact CUDA core count as the GTX 1660 OC, at 1408, and is based on the same 12 nm TU116 silicon. The GPU clock speeds are unchanged, too, with 1830 MHz core and 1785 MHz GPU Boost. The SUPER-charging of this SKU begins with its memory subsystem. The GeForce GTX 1660 SUPER Gaming OC gets 6 GB of GDDR6 memory clocked at 14 Gbps, which is faster than even the 12 Gbps GDDR6 memory found on the GTX 1660 Ti and on par with that of the much pricier RTX 2060 in terms of memory bandwidth—336 GB/s, a massive 75 percent increase over the GTX 1660. With it, NVIDIA hopes to shore up performance by up to 20 percent without touching the CUDA core count and stepping on the toes of the GTX 1660 Ti.
