AMD Ryzen 9 9950X “Zen 5” CPU Allegedly Features a FMAX Frequency of 5.85 GHz, Same As 7950X
AMD's Ryzen 9 9950X, the flagship Zen 5 CPU, reportedly features a maximum frequency or FMAX of up to 5.85 GHz, the same as Zen 4.
AMD's Zen 5 CPUs Might Peak Out With A Maximum Frequency of 5.85 GHz By Default, Ryzen 9 9950X Same As Ryzen 9 7950X
The FMAX or peak frequency is the maximum default clock limit allowed within the BIOS for the AMD Ryzen CPUs. The last-generation Ryzen 7000 CPUs based on the Zen 4 core architecture had FMAX set to 5.85 GHz for the top 7950X chip and it looks like that will remain the same for the next-generation flagship, the Ryzen 9 9950X which is powered by the Zen 5 core architecture. This latest information comes from Anandtech's Forum member, igor_kavinski, who allegedly sourced it from a user running an ES sample. The same user also revealed some early figures from a 9950X sample a while ago.

The AMD Ryzen 9 9950X is a 16-core chip with 32 threads, 64 MB of L3 cache, and a peak boost clock of 5.70 GHz, the same as the Ryzen 9 7950X. The CPU has the same TDP of 170 Watts and should go above 200W when PBO is activated.
We have talked about how the default operation of this chip will be cooler and consume lower power than the 7950X while offering higher performance and users can boost performance further using the PBO mode. The 5.85 GHz frequency is still a very high figure which these chips would be able to achieve in the right conditions such as better cooling and power when PBO is enabled.
With that said, the FMAX is different for each chip as we have seen in previous generations so while the Ryzen 9 9950X has an FMAX of 5.85 GHz, the rest of the chips will have lower FMAX frequencies. Following is a comparison:
- Ryzen 9 9950X - 5.85 GHz (5.7 GHz Boost)
- Ryzen 9 7950X - 5.85 GHz (5.7 GHz Boost)
- Ryzen 9 7900X - 5.70 GHz (5.6 GHz Boost)
- Ryzen 7 7700X - 5.50 GHz (5.4 GHz Boost)
- Ryzen 5 7600X - 5.45 GHz (5.3 GHz Boost)
- Ryzen 9
