AMD Zen5 architecture is allegedly 40% faster core-to-core than Zen4 in SPEC benchmarks

Rumor: AMD Zen5 is 40% faster than Zen4 in SPEC benchmarks

According to reputable leaker “Kepler_L2”, AMD’s next-gen CPU architecture is said to provide (up to) 40% increase over Zen4.

AMD’s Zen 5 CPU architecture appears to be gearing up for a major improvement over its predecessor, Zen 4, according to recent reports. Kepler suggests that in SPEC (Standard Performance Evaluation Corporation) benchmark tests, the single-core performance of AMD Zen 5 is purportedly 40% faster than Zen 4.

However, it hasn’t been explicitly stated whether this improvement is ‘up to’ or an average figure. If true, this leap in performance would mark a substantial upgrade for AMD, echoing the company’s original aim for the Zen (1) core architecture, which initially targeted a 40% increase in IPC (Instructions Per Clock), but ultimately surpassed expectations with a remarkable 52% improvement upon release over Excavator architecture.

The Zen5 architecture will power the upcoming “Granite Ridge” desktop CPUs which have recently been spotted in shipping manifests. Those CPUs will be a drop-in replacements for Raphael series based on Zen4. Users will not be required to upgrade the platform. Furthermore, Zen5 will debut under Strix Point, Strix Halo and Fire Range series on mobile platform.

Presumably the alleged SPEC performance increase is for the base Zen5 architecture, while the company is also expected to introduce Zen5c and later Zen5 with 3D V-Cache.
