Zen 5 will provide significant performance improvements, according to the father of AMD’s Zen architecture.


Something to look forward to: AMD stated that its Zen 5 processors would likely make their debut in 2024 during its last Financial Analyst Day in June 2022. Despite the fact that the company has not yet released any official Zen 5 benchmarks, we now have unofficial estimates of its performance and other metrics from a reliable insider.

The architect of AMD’s Zen CPU architecture, Jim Keller, has shared some crucial information about the Zen 5 processors that the company plans to release in 2019. Details about the performance, clock speeds, and power estimates of AMD’s upcoming lineup were revealed during a keynote address to university students in Bengaluru, India.

In addition to Zen 5, Keller, the CEO of AI hardware company Tenstorrent, discussed the company’s Ascalon processor cores and provided performance comparisons for a number of other data centre CPUs, including Intel’s Sapphire Rapids, Amazon’s Graviton 3, Nvidia’s Grace processors, and Zen 5.

Keller asserted that Ascalon will offer industry-leading integer performance-per-watt, and he predicted that Zen 5 will perform integer workloads 30 percent faster than Zen 4. Given that Zen 4 already outperformed Zen 3 by 15%, if that information proves to be true, it will be an impressive update.

In terms of clock rates, Keller predicted that the Zen 5 server chips would reach the 4 GHz mark. Depending on what Intel does with its Emerald Rapids lineup later this year, this could make the Zen 5 server chips the first in their category to reach those speeds. The EPYC Genoa and Sapphire Rapids processors, in contrast, are limited to speeds of 3.7 GHz and 3.8 GHz, respectively.

Due to a 4nm/3nm process node, Zen 5 chips are anticipated to be significantly more power-efficient than their predecessors despite having higher frequencies and better performance. Keller’s data also indicates that Zen 5 will end up being the fastest next-generation enterprise product, scoring 8.84 on the SPEC CPU 2017 INT Rate benchmark. In contrast, Grace may score 7.44 points, Sapphire Rapids is anticipated to score 7.45 points, and Zen 4 may only score 6.80 points.

It is important to note that Keller’s projections, not actual test results or even leaked specifications, are used to determine the performance, frequencies, and power estimates for the Zen 5. Therefore, don’t take them too seriously because they might not be entirely accurate.
