Monero Hashrate kH/s
The crypto currency Monero has been using the RandomX algorithm since November 2019. This PoW (proof of work) algorithm can only efficiently be calculated using a processor (CPU) or a graphics card (GPU). The CryptoNight algorithm was used for Monero until November 2019, but it could be calculated using ASICs. RandomX benefits from a high number of CPU cores, cache and a fast connection of the memory via as many memory channels as possible. Tested with XMRig v6.x under the operation system HiveOS.|

Devices using this processorBoth processors are based on the Zen 3 architecture (Vermeer) manufactured in the 7-nanometer procedure and came together in the fourth quarter 2020.
Before we come to the details of the processors, I would like to call the main difference in advance. The AMD Ryzen 9 5950X is a processor with 16 physical processor cores, whereas the AMD Ryzen 9 5900X must do with "only" 12 cores. Both processors can, thanks to free multiplier, overclock and support hyperthreading technology.
At the time of publication, these two processors belonged to the most powerful CPUs from the Ryzen 9 series from the CPU program of AMD.
Due to the different number of processor cores, they also differ differently. At the AMD Ryzen 9 5950X, the basic clock with 3.40 Gigahertz is specified and in turbomodus up to 4.90 Gigahertz (single-core capacity utilization) or 4,20 Gigahertz (multi-core utilization). The AMD Ryzen 9 5900x, however, has a slightly higher basic clock with 3.70 Gigahertz. The turbomodus for single core utilization allows a slightly lower clock of up to 4.80 gigahertz, in the utilization of all cores, the clock frequency with 4.50 gigahertz is slightly higher than in the comparison processor.
Both processors have 20 PCI Express lines in version 4.0 integrated and supported both AES-NI encryption and virtualization modes AMD-V and SEV.
At the memory, both the AMD Ryzen 9 5950x and the AMD Ryzen 9 5900x modules of the type DDR4-3200 support with a maximum size of 128 gigabytes.
