AMD Ryzen 5 9600X ES Engineering Edition Confirms Doubled Cache Bandwidth in AIDA64 Tests

Published by

Recently disclosed AIDA64 benchmark results for AMD’s Ryzen 5 9600X ES (Engineering Sample) have showcased significant enhancements in the cache performance compared to its predecessor, the Ryzen 5 7600X. Data from these benchmarks reveal that both the L1 and L2 cache bandwidths have nearly doubled, indicating substantial improvements in data processing capabilities of the newer CPU model. The detailed test results illustrate that the L1 cache bandwidth for the Ryzen 5 9600X ES measures 3756.4 GB/s for read, 1884.4 GB/s for write, and 3755.9 GB/s for copy operations, with a latency of 0.8 nanoseconds. In comparison, the Ryzen 5 7600X registered 2029.6 GB/s read, 1026.9 GB/s write, and 2048.1 GB/s copy, with slightly lower latency at 0.7 nanoseconds.

Similarly, the L2 cache bandwidth saw a marked increase, with the Ryzen 5 9600X ES achieving 1874.6 GB/s read, 1795.1 GB/s write, and 1859.7 GB/s copy. The latency recorded was 2.8 nanoseconds. This compares to the Ryzen 5 7600X, which recorded 1028.5 GB/s read, 1017.0 GB/s write, and 1017.6 GB/s copy, with a latency of 2.6 nanoseconds.


Interestingly, the L3 cache results diverged from this trend, with the Ryzen 5 9600X ES showing a slight decrease in bandwidth and an increase in latency over the Ryzen 5 7600X. Specifically, the Ryzen 5 9600X ES posted L3 cache speeds of 782.08 MB/s read, 771.46 GB/s write, and 772.32 GB/s copy, with a latency of 10.1 nanoseconds, compared to 847.82 GB/s read, 854.86 GB/s write, and 822.01 GB/s copy, with a latency of 9.7 nanoseconds in the Ryzen 5 7600X.


These results underscore AMD’s progress in cache design and efficiency, aligning with the company’s claims of up to a twofold increase in cache performance with the introduction of the Ryzen 9000 series based on the Zen 5 architecture. This enhancement is critical for applications that are sensitive to cache performance, including those requiring high-speed data access and processing. The Ryzen 5 9600X ES's doubled L1 and L2 cache capacities not only improve its own performance metrics but also suggest that AMD's forthcoming processors in the Ryzen 9000 series could see similar or greater improvements, making them potentially more competitive in both consumer and professional markets where processing speed and efficiency are paramount.
