At Computex 2024, AMD finally introduced the highly-anticipated AM5 processor family. Dr. Lisa Su, the AMD CEO, announced the Ryzen 9000 or “Granite Ridge” processors to a packed keynote in Taiwan, highlighting some of the latest technologies the CPUs would offer.

The series, which has a brand new Zen 5 architecture, will launch next month. First independent tests of the product have revealed that AMD was in fact correct with their keynote claims, with faster L1 and L2 caches than ever before.

AMD Ryzen improvements

While core count and clock speeds stay largely unaffected by the new architecture, AMD has claimed improved overall CPU performance as a result of doubled instruction and data bandwidth from L2 to L1 and L1 to FP registers. While a lot of the time claims like these can be exaggerated or partially true, independent bodies have finally been able to put these claims to the test. If you are wondering how these test scores came to pass, it is likely the result of users testing the original engineering samples of the product that were sent out prior to its announcement. The official review embargo for the Ryzen 9000 series has yet to be lifted.

A user online supposedly got their hands on a Ryzen 9 9600X processor, the lowest tier in the new lineup. This CPU features a 3.9 GHz base clock speed, and a 5.4 GHz boost clock, and comes equipped with 384 KB, 6 MB, and 32 MB of L1, L2, and L3 cache respectively. This processor only has CCD, unlike the 9900X and 9950X.

Results of latest testing

For the L1 cache, the Ryzen 9 9600X was ahead of the Ryzen 5 7600X. The read speeds are 85% higher, with write speeds and copy speeds both at 83% higher. However, the latency of the 9 9600X is 14% higher than Ryzen 5 7600X meaning what you make up in the L1 cache, you sacrifice slightly in latency. L2 cache shows a similar story with the Ryzen 9 9600X taking charge with 84%, 77%, and 83% improvements in write, read, and copy speeds respectively. L2 cache can help improve the system’s overall speed by providing a buffer between the CPU and RAM – which is good news for the new Ryzen products. With AMD’s latest range set to launch next month, we are excited to find out how they will perform and be received by fans.
