The second-best CPU in the Ryzen 7 line-up is the 1700X. Just like the flagship Ryzen 7 1800X, the 1700X has 8 cores, 16 threads and a wider extended frequency range (up to 100 MHz). But unlike the 1800X, the 1700X runs at a lower 3.4 base and 3.8 GHz boost (3.9 GHz with XFR). In fact, the only things different between these two CPUs are the base and boost frequencies — all other specs being the same.
