AMD Ryzen 7000 ‘Raphael’ CPUs Reportedly Have a 5.85GHz Maximum Frequency Cap

AMD Ryzen 7000 Desktop CPUs have appeared so far at pretty insane frequencies, clocking up to 5.5GHz on multiple threads. But it seems that the latest revision offers even higher CPU clocks, as reported by Angstronomics

AMD Ryzen 7000 ‘Raphael’ desktop CPUs reportedly have a maximum ‘Fmax’ frequency cap of 5.85GHz

Earlier this week, AMD corrected and confirmed a few more details on the Ryzen 7000 CPU lineup, codenamed Raphael. The company confirmed that the TDP of its best Ryzen 7000 CPUs will indeed be 170W and that the maximum package power of the AM5 (LGA 1718) socket will be 230W. The company too confirmed that the gaming demo shown at Computex 2022 was of a 16-core prototype running at 5.5GHz over multiple threads. But the company also confirmed, most importantly, that the prototype was running at a working range under the new 170W TDP specification.

AMD Mendocino APUs May Have Only Two RDNA 2 Computers

The Computex processor was a prototype with 16 cores that had not yet been fused to specific powers/TDP values, but operated in a range below the new 170W TDP group we developed. It is a conservative figure.

So we know that the AMD Ryzen 7000 Computex 2022 demo wasn’t a single-thread clock speed showcase and it wasn’t even a final prototype that used the full 170W TDP specification. Now, based on a report from the sources of Angstronomics, it appears that there exists a SKU (or an OPN) fused with a 5.85GHz Fmax or maximum frequency cap.

As for frequency targets, the game demo with maximum frequencies of 5.55GHz was also not with the final version. While Angstronomics is aware of an Ordering Part Number (OPN) that has been merged for a 5.85 GHz Fmaxwe’ll have to wait and see what the retail stepping fuses will be set to.

5.85GHz is an insane clock, but since we’ve only seen the first look at a prototype AMD Ryzen 7000 desktop CPU, the final spec could very well be in this range. A 16-core component using the full 170 watts available may well exceed 5.5GHz clocks and deliver clock speeds we’ve never seen before on an AMD Ryzen CPU. Intel is also aiming for similar clocks with its Raptor Lake-S Desktop CPUs so it makes sense for AMD to go up against the blue team in the clocks department, somewhere they’ve fallen behind in recent years.

We’re already excited to see 5.5GHz clocks for AMD Ryzen 7000 Desktop CPUs, so anything above would be a treat for consumers looking forward to building a brand new AM5 PC with the latest Zen 4 powered Ryzen 7000 Desktop CPUs. CPUs. Of course, such frequencies may only be allowed on the highest spectrum of AM5 motherboards, such as those based on the X670E chipset with loads of VRMs to meet the power delivery requirements for the new Fmax specification.
