The GeForce GTX 1660 SUPER will arrive on October 29 for $229. This card is based on the TU116 GPU and has 1408 CUDA cores, 88 TMUs, and 48 ROPs. It has a 192-bit memory bus with 6GB GDDR6 memory clocked at 14Gbps, resulting in memory bandwidth of 336GB/s. There will be no reference design from NVIDIA but it's said that you will need at least one eight-pin PCIe power connector. The TDP of this card is 125W, which is 5W more than the GDDR5-based GTX 1660. The memory is the only difference between both models.
The GeForce GTX 1650 SUPER reportedly gets a TU116 GPU with 1280 CUDA cores, which is quite a bit more than previously expected. This card is quite an upgrade versus the GTX 1650, with not only 4GB GDDR6 memory clocked at 12Gbps (versus 4GB GDDR5 clocked at 8Gbps), but also a 1530MHz core (vs 1485MHz) and a 1725MHz Boost (vs 1665MHz).
All these upgrades result in quite an increase in the TDP. The GTX 1650 has a 75W TDP but the GTX 1650 SUPER has 100W on its specification sheet. Shipments start on November 22 but the pricing of the GTX 1650 SUPER is still unknown.
Both cards also feature the Turing NVENC encoder.
