AMD Ryzen 7000 desktop CPUs have so far shown up with pretty crazy frequencies, clocking up to 5.5GHz on multiple threads. But it looks like the final revision could feature even higher CPU clock speeds, as reported by Angstronomics.
AMD Ryzen 7000 “Raphael” desktop CPUs reportedly have a maximum frequency limit “Fmax” of 5.85 GHz
Earlier this week, AMD corrected and confirmed some more details regarding its Ryzen 7000 CPU lineup, codenamed Raphael. The company confirmed that the TDP of its top Ryzen 7000 CPUs will indeed be 170W and the maximum package power of Socket AM5 (LGA 1718) will be 230W. The company also confirmed that the gaming demo presented during Computex 2022 was a 16-core prototype running at 5.5GHz across multiple threads. But most importantly, the company also confirmed that the prototype was running in an operating range below the new 170W TDP specification.
The Computex processor was a 16-core prototype sample that was not yet fused to specific power/TDP values, but was operating in a range below the new 170W TDP group we were developing. It’s a conservative number.

So we know that the AMD Ryzen 7000 Computex 2022 demo wasn’t a single-threaded clock speed demo, and wasn’t even a final prototype utilizing the full 170W TDP specification. Based on a report by Angstronomics sources, it now appears that there is an SKU (or OPN) that has merged with an Fmax or maximum frequency limit of 5.85GHz.
Regarding the frequency targets, the game demo with maximum frequencies of 5.55GHz was also not included in the final version. While Angstronomics is aware of an order part number (OPN) fused for a 5.85 GHz Fmaxwe have to wait and see how the step safeguards in retail are set.

5.85 GHz is an insane clock, but considering we’ve only seen the first glimpse of a prototype AMD Ryzen 7000 desktop CPU, the final spec could very well be in that range. A 16-core part utilizing the full 170 watts at its disposal can potentially surpass 5.5GHz clocks and deliver clock speeds we’ve never seen before on an AMD Ryzen CPU. Intel is also targeting similar clocks with its Raptor Lake-S desktop CPUs, so it makes sense for AMD to go head-to-head with the blue team in the clock department, where they’ve lagged behind in recent years.
We’re already looking forward to 5.5GHz clock speeds for AMD Ryzen 7000 desktop CPUs, so anything about that would be a treat for consumers looking forward to a brand new AM5 PC running the latest Zen 4-powered Ryzen 7000 desktop – Build CPUs. Of course, such frequencies might only be allowed on the highest spectrum of AM5 motherboards, e.g. B. those based on the X670E chipset with many VRMs to meet the power supply requirements for the new Fmax specification.
