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

AMD Zen 5 CPU Architecture Rumored To Feature An IPC Increase of Around 10% According To Lenovo's Manager

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.

Now, information coming from Lenovo China's manager at Weibo seems to give us a hint at the IPC of the next-generation core architecture. The same manager also pointed out that the Lenovo 8050 APU leak was not true which was later verified by ASUS's leak. A few weeks ago, he also mentioned the recent Zen 5 performance rumors which claimed that Zen 5 CPU was up to 40% faster per core versus Zen 4. While the rumor never talked about IPC and only talked about a specific SPEC result, it looks like we might have our first revelation of where the Zen 5 IPC might land.

As per the details, the AMD Zen 5 core architecture for next-gen Ryzen and EPYC CPUs is expected to deliver an IPC increase of around 10%. It is also mentioned that the IPC is more than 10% when selecting the Cinebench R23 1T (Single-Thread) test. AMD's Zen core architectures have always shown good performance results in Cinebench tests, whether they be multi-thread, single-thread, or IPC figures. Following 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.

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.
