AMD Zen 5 CPUs Rumored To Feature Around 10% IPC Increase, Slightly More In Cinebench R23 Single-Thread Test

AMD's Zen 5 CPUs are rumored to offer an IPC increase of around 10% with the latest core architecture.

The AMD Zen 5 CPU architecture is rumored to increase IPC by around 10 percent, according to a Lenovo manager.

AMD's next-generation Zen 5 core architecture is coming soon to Computex 2024. We have seen a range of CPU leaks, mostly Strix Point “Ryzen AI HX” And Granite Ridge “Ryzen 9000” familyWhich shows us that the next generation architecture is ready for launch in the second half of the year.

Now, the information is coming. Lenovo China Manager at Weibo It looks like we get a hint of the next generation core architecture IPC. The same manager also pointed out that the Lenovo 8050 APU leak was not correct which was later confirmed by the ASUS leak. A few weeks ago he also mentioned it. Recent Zen 5 performance rumors claimed that the Zen 5 CPU was up to 40% faster per core versus the Zen 4.. While the rumor never talked about IPC and only talked about the results of a specific SPEC, it looks like we might have the first reveal of where the Zen 5 IPC might land.

According to the specifications, the AMD Zen 5 core architecture is expected to offer an IPC increase of around 10% for next-generation Ryzen and EPYC CPUs. It is also mentioned that the IPC is more than 10% when choosing the Cinebench R23 1T (single thread) test. AMD's Zen core architectures have always shown good performance results in Cinebench tests, be it multi-threaded, single-threaded, or IPC figures. The IPC breakdown for the respective generation of Zen architecture is as follows:

  • Excavator up to Zen 1: 52% IPC increase
  • Zen 1 to Zen+: 3% IPC increase
  • Zen + to Zen 2: 15% IPC increase
  • Zen 2 to Zen 3: 19% IPC increase
  • Zen 3 to Zen 4: 13% IPC increase
  • Zen 4 to Zen 5: ~10% IPC increase

While the roughly 10% increase in IPC is smaller than the Zen architectures that came before (minus Zen+ which was mostly a cool refresh), these claims may very well be based on early prototypes. It is likely that with the final silicon, the IPC could end up being closer to 15% which would be a very respectable increase.

Not much is known about AMD's Zen 5 core architecture at the moment, but the following highlights are what we do know officially:

  • Improved efficiency and performance
  • Again the pipeline front-end and wider issue
  • Integrated AI and machine learning optimizations

Additionally, it has been mentioned that starting with AMD's Strix Point “Ryzen AI HX” APUs, Red Team will stop providing Windows 10 drivers which makes sense for the AI ​​PC platform. How many are marketing these upcoming chips? To make full use of the onboard AI NPUs that offer 45 AI TOPs and a total of 77 platform tops, Microsoft will fuse its next-generation Windows 11 OS updates with more Copilot and AI-intensive features.
