AMD’s Ryzen 9 7950X, the incoming flagship for next-gen Zen 4 processors, has been spotted boosting to 5.85GHz – but there are caveats to be had here.
This latest Zen 4 leak comes from a Weibo (opens in new tab) user (a social media platform in China), so should be treated with more caution than usual, and it was flagged by HXL on Twitter (a regular source of hardware leakage, with the tweet highlighted by VideoCardz (opens in new tab)).

As you can see, the leaker reportedly has a Ryzen 9 7950X that hits 5.85GHz, as mentioned – requiring huge amounts of salt, of course, and exactly what that speed means we’ll discuss shortly – and Intel’s Raptor Lake flagship will apparently reach 5.8GHz at top speed in comparison.
The 5.85GHz speed matches an earlier top speed that Angstronomics (a well-thought-out resource) released for the flagship Zen 4 (a well-thought-out resource), and the Weibo leaker also offers a CPU-Z screenshot of the pre-release 7950X.
Analysis: however you roll it, the 7950X looks pretty sharp
Obviously this is one we should be pretty skeptical about, but if true, the 7950X capable of that kind of boost is clearly an eye opener. Now the leaker makes the point that the Ryzen CPU is actually boosted to 5.7GHz, with 5.85GHz recorded via PBO (Precision Boost Overdrive – in other words, the automated overclocking mode you can enable to get some more performance out of your chip to get).
However, as another well-known Twitter leaker (Uzzi38 (opens in new tab)) comes in, what actually happens with this monster 7950X is that it hits 5.85 GHz without the need for PBO, but this is just a peak frequency – probably reached quite briefly, here and there. In other words, the quoted maximum boost on the box of the flagship Zen 4 chip will be lower than this (more like the 5.7 GHz mentioned).
Exact speeds will, as always, depend on the quality of the processor you buy – there’s always some variation within CPU models, known as the silicon lottery – but either way AMD will have an official (default) maximum boost which is set to an appropriate low level so that all chips can hit reliably for obvious reasons.
Whatever the case for the exact top speed for the Ryzen 9 7950X, it looks like it will be very close to the same margin as the Raptor Lake champion, the Core i9-13900K. Again, this is another hint that the battle between Zen 4 and Intel’s 13th generation silicon will be very close.
We’ll know a lot more about Ryzen 7000 tomorrow as AMD has its launch event for the next-gen processors via a live stream. There’s a good chance we’ll find out the official boost speed rating for the flagship 7950X during this event.
