AMD Ryzen 9 7950X Frequency could Peak at at 5.85 GHz
At stock multiplier settings, Fmax (or Frequency max) is the maximum clock speed that an AMD "Zen" CPU will automatically boost/overclock to.
You'll need to increase the multiplier value and overclock manually to go above this. AMD's forthcoming flagship desktop CPU, the Ryzen 9 7950X "Zen 4," is said to have a Fmax of 5.85 GHz. You'll need to enable options like Precision Boost Overdrive (PBO) to eliminate the power limits required to get here.
Importantly, the F-max frequency for Ryzen 5000 series may still be tweaked via F-max Offset, implying that Ryzen 7000 series can still clock higher until AMD changes the underlying technology for Zen4 design. Angstronomics originally mentioned the F-max frequency of 5.85 GHz in May of this year. This frequency, however, was not associated with any SKU at the time.
AMD's Ryzen 9 7950X is a 16-core processor that uses the Zen4 microarchitecture. It is said to have two CCDs with 16 cores dubbed "Persephone." According to the leaker, the top CPU fight will be between the 7950X's 5.85 GHz and the i9-13900K, which will allegedly boost up to 5.8 GHz with Thermal Velocity Boost. In addition to those assertions, the leaker included a screenshot of the Ryzen 9 7950X CPU, which is not yet fully supported by the software. It indicates 16 cores with a core speed of 4848 MHz clock, but no indication of the workload. AVX512 support is also mentioned in the instructions.

Today is just marketing BS. The big day will be when these can actually be tested (and tests revealed to the public) - unfortunately thats often the same day as the actual retail availability, so people are forced to buy blind if they want one early.

It`s mostly marketing BS but also some important stuff, like release dates, available SKUs and prices.
As for buying the CPUs without seeing any reviews, that`s a risk easily avoided...

This is a little concerning to me. Seems like AMD is throwing everything they've got at this. I'm sure this is just so they can barely top out Intel, but they better hope to have another trick up their sleeves after this generation because Intel is playing the same game of ridiculous clocks.
Then again, I personally don't really care about such CPUs or specs. I'm not willing to spend that kind of money for the sake of a pissing contest. I just want the chip that does what I need it to do for a reasonable price and good performance-per-watt. This chip will be none of those things.

Today is the big day for AMD. This is very cool news. We're going to experience great competition between Intel and AMD. For me personally it looks like I'm going to flip a coin.
