The Ryzen 7000X3D processors won’t support multiplier-based overclocking after all. Contrary to what was reported the other day, the Zen 4 3D V-Cache chips will have a locked multiplier. The only difference is that, unlike their predecessor, Precision Boost Overdrive (PBO) and curve optimization will both be available. For reference. PBO is useful for multi-threaded workloads like rendering and video editing. It raises the power envelope, allowing more cores to hit the peak boost clock and for longer durations.
Ryzen 7000X3D Series processors are unlocked for memory and infinity fabric overclocking, just like Ryzen 5800X3D. New to the 7000X3D, we have also added PBO and Curve Optimizer capabilities.AMD
In an official statement, AMD has notified the press that memory and Infinity Fabric overclocking will remain unlocked on the Ryzen 7000X3D processors. Multiplier-based overclocking will be disabled, but Precision Boost Overdrive and Curve Optimization will be available.
|Boost / Base Frequency
|AMD Ryzen 9 7950X3D
|Up to 5.7 GHz / 4.2 GHz

The Ryzen 7 7800X3D will come with a boost clock of 5GHz and a total cache of 104MB. The Ryzen 9 7900X3D will have a base and boost clock of 4.4GHz and 5.6GHz, respectively. It’ll pack 140MB of cache memory, including 128MB of L3 cache. The 7950X3D will feature an additional 4MB of L1/L2 cache alongside a peak single-core boost of 5.7GHz.
