170W 8-Core AMD Zen 5 CPU found in shipping manifest

AMD’s top 8-core Zen 5 CPU could have a TDP of 170W

Next-generation AMD Ryzen CPUs have been found in shipping manifests. These AMD Zen 5 “Granite Ridge” CPUs appear to be engineering samples, prototypes for the company’s next-generation Ryzen CPU lineup.

6-core and 8-core Zen 5 “Granite Ridge” CPUs have been spotted. These CPUs have TDPs of 105W and 170W respectively. This 8-core model has a much higher TDP than AMD’s existing Zen 4 105W Ryzen 7 7700X processor. This suggests that AMD Zen 5 CPUs will be more power hungry than their predecessors.

Recent rumours have suggested that AMD’s Zen 5 Ryzen processors will deliver a significant performance boost over their Zen 4 predecessors. One leaked benchmark showcased an alleged 40% performance improvement.

With Zen 5, AMD has stated that they are building a “new grounds up microarchitecture”. This suggests that AMD’s Zen 5 CPU cores will feature a large number of design changes over Zen 4. In theory, this creates many avenues for performance gains with Zen 5.

AMD has to deliver large IPC gains with Zen 5

With Zen 5, AMD are reportedly maintaining the same core counts as their existing Zen 4 processors. That’s means that AMD’s probably planning to release a 16 core Zen 5 Ryzen flagship on their AM5 platform. To achieve significant performance gains with their new architecture, AMD will not be relying on CPU higher core counts. AMD needs to deliver more per-core CPU performance with their next-generation CPU architecture. Only increased CPU clock speeds or IPC gains can achieve this. With Zen 5, AMD’s reportedly achieve no major clock speed gains with their new architecture. That leaves IPC gains as Zen 5’s only performance-boosting aspect.
