At the Computex Keynote, AMD’s CEO, Dr. Lisa Su, caused a stir by revealing the Ryzen 9000 series of AM5 CPUs. The forthcoming series debuts the new Zen 5 core architecture and is scheduled to launch next month.

Despite maintaining the same core count and clock rates in the new model, AMD states that the Zen 5 architecture notably boosts CPU core performance by doubling instruction and data bandwidth from L2 to L1 and L1 to FP registers. Preliminary information indicates that a 6-core Ryzen 5 9600X CPU boasts a base frequency of 3.9GHz, with a turbo boost up to 5.4GHz. Moreover, it features 384 KB of L1 cache, 6 MB of L2 cache, and 32 MB of L3 cache.

The AMD Ryzen 9000 series processors are not yet accessible to the general public, but leaked benchmarks, as shared by HXL, imply that some companies have had access to engineering samples. In the AIDA64 L1 cache benchmark, the Ryzen 9 9600X surpasses the Ryzen 5 7600X, indicating roughly 85% faster read speeds, 83% faster write speeds, and 83% faster copy speeds. Nevertheless, the Ryzen 9 9600X does exhibit 14% higher latency in comparison to the Ryzen 5 7600X.

The Ryzen 9 9600X showcases a significant advantage in L2 cache performance, with approximately 84% higher read speed, 77% higher write speed, and around 83% higher copy speed when juxtaposed with the Ryzen 5 7600X. Conversely, the L3 cache performance was generally inferior, displaying 8% lower read and write speeds, 6% lower copy speeds, and a 4% lower latency. In the CPU-Z built-in test, the engineering sample performed similarly to an overclocked Ryzen 7600X (5.45GHz) in both single- and multi-thread evaluations. Nonetheless, retail samples are expected to offer superior performance as the engineering sample runs at 5.05GHz.

Following this leak, HXL provided an update with additional CPU-Z results, with the CPU overclocked to 5.7GHz. In this scenario, the CPU demonstrated a notable improvement, surpassing the overclocked Ryzen 5 7600X by 14% in single-thread performance and 13% in multi-thread assessments.
