AMD Zen 5 CPUs Going to Offer Only 10% IPC Uplift, Says Lenovo Manager

AMD’s Zen 5 CPUs are rumored to feature an IPC (Instructions Per Cycle) increase of around 10%. This information comes from Lenovo China’s manager at Weibo. The IPC is expected to be slightly more than 10% when selecting the Cinebench R23 1T (Single-Thread) test.

Zen 5 CPU Architecture

AMD’s next-generation Zen 5 core architecture is about to debut soon as we near Computex 2024. We have seen a range of CPU leaks, mostly the Strix Point “Ryzen AI HX” and Granite Ridge “Ryzen 9000” families, which show us that the next-generation architecture is ready for launch in the 2nd half of the year.

IPC Increase Over the Years

Here is the breakdown of IPC for the respective generation of Zen architecture:

• Excavator 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

Although an IPC increase of around 10% is smaller than the Zen architectures that came before (minus Zen+ which was mostly an optimized refresh), these claims may very well be based on early samples. It is likely that with the final silicon, the IPC could end up close to 15% which will be a very respectable increase.

Enhanced Performance and Efficiency

Not a lot about AMD’s Zen 5 core architecture is known at the moment but following highlights are what we officially know:

• Enhanced performance and efficiency
• Re-pipelined front-end and wide issue
• Integrated AI and Machine Learning optimizations

Furthermore, it is mentioned that starting AMD’s Strix Point “Ryzen AI HX” APUs, the red team will stop providing Windows 10 drivers which makes sense given how much they are marketing these upcoming chips for the AI PC platform.

Conclusion

To make full use of the AI NPUs onboard which should offer up to 45 AI TOPs and a total of 77 platform TOPS, Microsoft will fuse its next-gen Windows 11 OS updates with more Copilot and AI-intensive features. As we near the launch of the Zen 5 CPUs, we can expect more details to emerge. Stay tuned for more updates!
