AIDA64 CPU and Memory
Memory Read
The memory is running at DDR4-3600 CL16 on both CPUs, and we see identical performance between the CPUs on memory read performance at around 50GB/s.
Memory Write
The same is also true on memory write performance, both CPUs are pulling 28GB/s of memory write speeds.
CPU Queen
The CPU Queen test is an integer benchmark that focuses on branch prediction and misprediction penalties. It is multi-threading aware. The AMD Ryzen 7 5800X is 12% faster than the Ryzen 7 3700X in this simple integer benchmark test. PBO adds just 1% more performance.
AES
Here is the definition from AIDA64 of what this test does exactly, scroll down to AES.
In very complex AES encryption, the Ryzen 7 5800X has a huge advantage over the Ryzen 7 3700X, it’s a whopping 100% faster! PBO adds about 1% more performance.
SHA3
Here is the definition from AIDA64 of what this test does exactly.
The AMD Ryzen 7 5800X sees a 51% performance improvement in SHA3 versus the Ryzen 7 3700X. PBO advantage is negligible. It seems AES and SHA3 are vastly faster on Zen 3 versus Zen 2.
Cache and Memory Benchmark
If you would like to compare the L1, L2, and L3 cache performance and latencies, we will show the screenshots from AIDA64’s Cache and Memory Benchmark below. You can see how the cache performance changes between the Ryzen 7 3700X and Ryzen 7 5800X.
