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.|

Estimated results for PassMark CPU Mark
Some of the CPUs listed below have been benchmarked by CPU-monkey. However the majority of CPUs have not been tested and the results have been estimated by a CPU-monkey’s secret proprietary formula. As such they do not accurately reflect the actual Passmark CPU mark values and are not endorsed by PassMark Software Pty Ltd.|

Devices using this processorThe AMD Ryzen 7 5800X is an 8 core processor with SMT (Hyperthreading) support. It can process up to 16 threads simultaneously and therefore represents a very good compromise between performance and energy consumption. Unlike the Ryzen 3xxx, the new Ryzen 5xxx processors connect 8 CPU cores per chiplet, the level 3 cache of the AMD Ryzen 7 5800X is 32 MB.
The AMD Ryzen 9 5900X, on the other hand, has a full 12 cores, which also supports SMT and can process 24 threads at the same time. Both processors can be overclocked if the mainboard chipset allows it. It is based on 2 chipplets and therefore has a 64 MB level 3 cache.
Since the Ryzen 5xxx desktop processors do not have an iGPU, a dedicated graphics card is required for operation. This can then be connected to the processor via PCIe 4.0. The processors have 20 usable PCIe 4.0 lines (4 are required for internal I / O). The 20 lines enable, for example, the connection of a graphics card with 16 lines and a fast PCIe 4.0 M.2 SSD with 4 additional lines.
RAM connect both processors with up to DDR4-3200, but higher clock frequencies of the RAM are also possible via overclocking. A maximum of 128 GB of RAM is supported, with two memory channels being available. Since operation in "dual-channel" mode doubles the memory bandwidth, at least two main memory modules should always be installed in the system.
Both processors have a TDP of 105 watts, whereby the 12-core processor AMD Ryzen 9 5900X has a higher energy consumption than the smaller 8-core processor.
