AIDA64 CPU Benchmarks
Now we will look at some specific AIDA64 CPU Benchmarks that test specific parts of the CPUs. The AIDA64 Zlib test is an integer benchmark that measures combined CPU and memory subsystem performance through the public ZLib compression library. The AIDA64 AES benchmark measures CPU performance using AES (Advanced Encryption Standard) data encryption. In cryptography, AES is a symmetric-key encryption standard. AES is used in several compression tools today, like 7z, RAR, and WinZip, and also in disk encryption solutions like BitLocker.
Memory Bandwidth
In the graph above, we are testing straight-up memory bandwidth of read and write performance. The first thing we will get out of the way is that yes, Intel has much higher memory bandwidth on read and write performance, this is not new, but on the LGA1700 platform with DDR5 at 7200MT/s nothing touches the raw bandwidth they provide. Now, let’s focus on the AMD results.
All of the Ryzen 7000 and Ryzen 9000 CPUs provide 78GB/s of read memory bandwidth and 79GB/s of write memory bandwidth. There is no difference between these two generations, and therefore the AMD Ryzen 9 9900X has no change in memory bandwidth.
CPU Zlib
Zlib test is an integer-based test, and we find that the AMD Ryzen 9 9900X has a 12% performance uplift over the previous generation Ryzen 9 7900X. Compared to the Intel Core i9-14900K, it is 14% slower.
CPU AES
We know that Zen 5 responds extremely well to AVX performance, and so here with AES we find the new AMD Ryzen 9 9900X is 80% faster than the Ryzen 9 7900X. It also means that the AMD Ryzen 9 9900X is 37% faster than the 16-core Ryzen 9 7950X and 79% faster than the Intel Core i9-14900K.
