It's an RTX series part so the RTX 3050 has ray tracing support and possibly includes Tensor cores. Kopite7kimi says the TGP is 90W so that indicates a PCIe power connector will be required.
There's no word about the memory configuration but VideoCardz expects it will be a 192-bit memory bus with 4GB GDDR6 memory.

The GeForce RTX 3050 is expected in January, but these dates can still change of course. The GA106-based RTX 3050 Ti and RTX 3060 will compete with AMD's Navi 22. The RTX 3060 is expected in January with the RTX 3050 Ti following in February. AMD's Navi 22-based RX 6700 series is also expected in early 2021. Then there's also the GeForce RTX 3060 Ti, that's another GA104-based part slated for a December 2nd release if the rumor mill is to be believed.
The NVIDIA GA106 GPU will compete directly with AMD Navi 22, the upcoming mid-range processors also expected to debut early next year. According to our sources, AMD will launch the first Navi 22 products under Radeon RX 6700 series. The processor would feature up to 40 CUs and 192-bit memory bus. Thus, the RX 6700 XT might feature the exact same core count as the RX 5700 XT, 40 CUs (2560 SPs). However, unlike Navi 10, the Navi 22 GPU would feature a 192-bit memory bus.
