I'm confused as well, but to extend elstaci's answer to cover more bases in case you are asking if Socket AM4 comes in a dual socket model, Socket AM4 motherboards do not come in dual socket models, but the Ryzen 3950X does have 16 cores/32 threads. It is a powerful processors, but requires equally powerful LIQUID COOLING, such as the Corsair H150, to exact the maximum amount of performance. It doesn't have the quad channel memory controller found in Threadripper though, so memory intensive programs will suffer.
