Last summer, AMD launched its 7nm Ryzen 3000 family and took a leadership position in the overall CPU market. While the Intel Core family retains the crown in lower-resolution gaming, AMD has a commanding seat in the market as a whole. This is particularly true at the upper end, where the Ryzen 9 3900X lives, though that part was difficult to find for months after launch and is still selling for above MSRP on some sites.
AMD briefly released a Product Master guide with reference to a Ryzen 7 3750X, with a 105W TDP. There’s very little data on the part beyond its core count (8 cores, 16 threads) and its TDP (105W), and the original link has been pulled.

The Ryzen 7 3800X is a 3.9GHz base / 4.5GHz boost CPU, with a 105W TDP. The Ryzen 7 3700X is a 3.6GHz base, 4.4GHz boost CPU, with a 65W TDP. The most logical conclusion, if the Ryzen 7 3750X chip exists at all, is that it would be a chip with a base clock of 3.7GHz or 3.8GHz, but a boost clock no higher than the 3800X.
This is a rather odd spot to try and stuff a new eight-core CPU, and it’s not clear what to make of the potential part. One potential answer is that the 3750X represents CPUs not quite good enough to make the cut as 3800X’s, but better than the 3700X’s AMD is currently selling.
This could, in turn, be related to the higher clock speed issues that AMD has been grappling with. AMD has released UEFI updates to improve its clock speed targeting (and testing showed that clocks improved by 25-50MHz in many cases, as per AMD’s guidance). This will have improved the number of CPUs
that hit their full target boost clock on at least one core, but may not have been a sufficiently large improvement to put every single CPU at full boost clock on at least one core. The best available data suggests higher clock speeds may still be difficult. Raising base clock, however, would likely be easier.
The 3750X could also be an attempt to respond to the upcoming Intel Core i9-9900KS, but again, that’s an uncertain argument. The 3750X could theoretically be a double-cache part — there’s a rumor to that effect, with 64MB of L3 instead of 32MB, and one quad-core CCX active on each chiplet. This could make sense if the 3750X is an effort by AMD to rehabilitate bad die with good L3 cache yield. Without knowing more about where the errors on AMD’s 7nm wafers are concentrated, we can’t know if this adequately describes the yield situation.
For now, we figure the 9900KS will be opposed by the 3700X, 3800X, and Ryzen 9 3900X. If a Ryzen 7 3750X is indeed on the way, we will find out about it. It’s also possible that the part is a semi-custom chip produced for a specific customer, or intended for a specific geographical area. It might be a real core, but not one intended for US markets.
