SiSoftware Sandra and AIDA64
SiSoftware Sandra
We are now testing in the popular SiSoftware Sandra 2021 version. We are testing the CPU arithmetic section. In this graph above we are looking at Dhrystone integer performance in multi-threading. We find that the AMD Ryzen 7 5800X is 4% faster than the Ryzen 7 5800X3D thanks to the higher all-core CPU boost clock speed.
The same is true in single-core testing where the 5800X is 6% faster than the 5800X3D.
In multimedia performance, the Ryzen 7 5800X in multi-threading is also 4% faster than the Ryzen 7 5800X3D.
In single-threading performance, the Ryzen 7 5800X is 7% faster than the Ryzen 7 5800X3D, again because in single-threading the 5800X can boost higher than its all-core multi-threading clock speed, and has a bigger advantage in clock speed than compared to the 5800X3D.
AIDA64
We are now going to use AIDA64’s Cache and Memory benchmark to look at RAM memory bandwidth and RAM and cache latencies between both CPUs.
The Ryzen 7 5800X3D and Ryzen 7 5800X have the same memory read and write bandwidth and latency as expected. What is most interesting is the L3 cache, the latencies are very similar between both CPUs so AMD has done great things in keeping latencies low on the new 3D V-Cache on the Ryzen 7 5800X3D.
