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 processorIf applications or benchmarks can use all CPU cores of the processors, Intel's 11th generation Core i9 only sees the rear lights of the AMD Ryzen 9 5900X. This can set itself apart from the Intel Core i9 by between 25 and 30%, which is due to the significantly higher number of cores of 12 (24 threads) compared to only 8 (16 threads) of the i9.
Actually, Intel wanted to manufacture the "Rocket Lake S" processors with a new architecture in 10 nm. Presumably due to delivery or production problems, Intel has decided to implement a backport to the tried and tested, but outdated 14 nm production. This is probably the reason why Intel has given the "Rocket Lake S" processors a maximum of 8 CPU cores.
AMD has more room here and can implement up to 16 CPU cores on the AM4 socket. The successor socket should even come with twice the number of CPU cores. New in the Intel Core i9-11900K is the support of PCIe 4.0, which AMD has supported since the previous generation (Ryzen 3xxx). This allows new M.2 SSDs to be connected to the system very quickly. Transfer rates of 7.5 GB / s are possible via four PCIe 4.0 lines.
Both CPUs support 128 GB of RAM of the DDR4-3200 type in two memory channels and achieve transfer rates of approx. 55-60 GB per second. If you want to use faster memory, you can do so with both processors. Intel uses the so-called XMP overclocking profiles that AMD uses with D.O.C.P. similarly supported. Manual overclocking is of course also possible. Both processors manage up to DDR4-3600 without any problems.
