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
