As Tom's Hardware suggests, there's no guarantee that this processor will make it past the drawing board:
With those specifications in mind, the Ryzen 7 3750X could be leftover chips that didn't make qualifications for a Ryzen 7 3800X but are still superior over the Ryzen 7 3700X. With TSMC's rumored struggles with 7nm orders, AMD is probably eager to maximize its margins on every single chip it can get.On a related note, the same document also yielded information about the Renoir APU series. Mobile versions are expected first, perhaps at CES 2020 in January.
Technically, the Ryzen 7 3750X could squeeze between its counterparts. There's a 300 MHz and 100 MHz gap in between the Ryzen 7 3700X and Ryzen 7 3800X base and boost clocks, respectively. The Ryzen 7 3750X seemingly rocks a 105W TDP, so it should be faster than the Ryzen 7 3700X. In regards to pricing, the Ryzen 7 3700X and Ryzen 7 3800X have a $329 and $399 MSRP, respectively. That's a $70 difference, so AMD could push the Ryzen 7 3750X into the stack if the chipmaker really wants to.
