AMD confirms next-generation Zen 5 CPU microarchitecture, Zen 4 just 8–10% faster IPC
It's a bit early and ambitious but in its Financial Analyst Day 2022 presentation AMD is creating some waves with the mention of Zen 5 CPU microarchitecture.
AMD revealed Ryzen 7000 during Computex 2022: The manufacturer claimed "over 15 percent" improved single-thread performance as a result of enhanced IPC and higher clock speeds of more than 5.0 GHz, PCIe 5.0 and always an integrated RDNA-2 GPU. Variations of the company's Zen 4 die paired 3D Vertical Cache (3DV Cache) are planned, AMD also mentions that it has met its design goal for its current "Zen 3" architecture by building it on both 7 nm and 6 nm node processes (Rembrandt). Zen 4 architecture will be released on the 5 nm node (TSMC N5) and may see a shrink to the newer 4 nm node in the future.
The following Zen 5 design would be introduced at 4 nm, with an optional shrink to 3 nm. Zen 5 and based on that EPYC "Turn" processors would be available in 2024.
Built on 5nm technology, the slide above shows that instructions per clock (IPC) have improved by 8–10% over the current Zen 3. AMD says that higher frequencies boost single-thread performance by 15%. Zen4 will also introduce an extra Vcache.

You mean Zen 4? Raptorlake is releasing later this year. The 8-10% + 15% clockspeed is for Zen 4, we don't know what Zen 5 will bring - if they are indeed refreshing the entire uarch it might be significant. Remember AMD/Papermaster did say they wanted to start from scratch far more often -- even Jim Keller in an interview when was with Intel said there should be a blank slate every 5 years or so.
That being said I agree with you generally.. Zen 4 looks like it will bring performance parity/slight lead over alderlake but raptorlake is launching at the same time as Z4.
If this is all they got they are going to be in trouble. Apple and Intel are already ahead performance wise in single thread with their recent architectures and are going to pull even further ahead with their next architecture updates due to be released more or less around the same time as Zen 5. I sure hope AMD can make these processors affordable and accessible so so they can compete on that front.

except amd are the only ones that can put over 8 performance cores on a cpu and not have it raise the ocean level

it's 15 altogether
half is ipc half is clocks

i think their focus is on platform, that will be the most impressive part
also,how nice is it that 15% is now considered a little disappointing.
imo whoever is set on buying ddr5 shouldn't even think about intel atm.
get am5 and enjoy 5-6 years of upgrading the cpu without a new board
if you're staying on ddr4 though, intel is just way ahead in value with b660 + ddr 4 + 12600k
btw its15 for st only,mt is going to be 40
