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.
You will notice that all Ryzen CPUs here with dual-CCDs, perform exactly the same on memory read and write performance. Whether it is the Ryzen 7000 series or the new Ryzen 9000 series, we are getting about 78GB/s of read memory bandwidth and about 79GB/s of write memory bandwidth. There is nothing shocking, or new about this performance from the last generation to this generation.
CPU Zlib
Zlib test is an integer-based test, and here we see that the new AMD Ryzen 9 9950X is 10% faster than the previous generation Ryzen 9 7950X, so that’s a decent uplift in integer performance. Compared to the 7950X3D the AMD Ryzen 9 9950X is 16% faster. Compared to the Intel Core i9-14900K the AMD Ryzen 9 9950X is 11% faster. Compared to the Ryzen 9 9900X the higher core count AMD Ryzen 9 9950X is 29% faster, showing what more cores can do for you in integer performance.
CPU AES
Similar to our previous Zen 5 testing, Zen 5’s claim to fame is its AVX performance uplifts, and here we see the AMD Ryzen 9 9950X is a whopping and shocking 78% performance uplift from the previous generation 7950X. Compared to the 7950X3D it is 90% faster. We even see that it beats the snot out of the Intel Core i9-14900K at 134% faster! Compared to the lower core count 9900X the AMD Ryzen 9 9950X is 30% faster with more cores.
