Zen 5 was known from the beginning as an architecture that would bring a higher increase in IPC, but no major shift in clock frequencies. Low units of hundreds of MHz were expected at most. Soon, however, TSMC began to experience some hiccups with the preparation of the 3nm process. AMD, which had already announced in advance that it would design processor architectures in such a way that, if necessary, they could use a generation older production process, actually changed their plans and modified the design originally prepared for 3nm lines to the 4nm process (which is a rather fundamental difference, it is a derivative of the 5nm technology with which it is compatible).
This is because AMD prefers a slightly different strategy than the one held by Intel until recently, which is to prefer the timely release of the product rather than its postponements in an attempt to stick to the original plans (parameters) at all costs. It can be noted that Intel is also trying to implement this strategy as much as possible, which can be seen, for example, in the release of (at least) the 144-core Xeon Sierra Forest (instead of delaying the release until a more powerful model is ready) or trying to release at least a mobile this year Meteor Lake instead of another delay and waiting for the desktop version to finish.

However, it is understandable that a design with a higher number of transistors originally developed for the 3nm process will not achieve the originally targeted clocks on the 4nm process. It has been rumored for some time that there will be some reduction. According to the current information of the YouTube channel RGT, it is currently expected to be roughly 200-300MHz reduction compared to Zen 4which would mean about 5.4-5.5 GHz for the top of the line model (Ryzen 9 8950X?).
It is therefore a roughly 3.5-5% loss, which should, however, be more than compensated by the increase in IPC. Zen 5 is set to deliver the biggest increase in IPC between two generations Zenu occurred. It brought the highest value so far Zen 3 with 19 %, so in Zen 5 more than 20% can be expected (probably something in the range of roughly 20-25% in average loads). Even with a slight frequency loss, the intergenerational power shift could be at least around 20%.
Edition Zen 5 for desktop is expected in the second quarter (spring) of 2024, i.e. in 6-9 months. A mobile APU is expected in the summer Strix Point with cores Zen 5 + Zen 5c and sometime later in the year, a powerful Sarlak APU with gaming graphics. Before Christmas 2024 or after (in January at CES 2025) it is to follow Zen 5 with V-cache (Ryzen 8000X3D). Presumably as a reaction to the one being prepared by Intel Arrow Lake.
