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.

Intel Core i7-11700K AMD Ryzen 7 5800X
Unknown Unknown
A direct comparison between the Intel Core i7-11700K and the AMD Ryzen 7 5800X only makes it clear how close the two competitors AMD and Intel are currently. In the case of the Intel Core i7-11700K, Intel was able to significantly increase the raw performance per clock, but has not yet reached the IPC that AMD achieves with Zen 3 technology. Therefore, Intel gave the Intel Core i7-11700K a 300 to 400 MHz higher clock to catch up with the AMD Ryzen 7 5800X.

The Intel Core i7-11700K does this quite well. The 8-core processor is only slightly behind the AMD Ryzen 7 5800X in benchmarks. Intel's new Rocket Lake architecture is used in the Intel Core i7-11700K, which is actually a backport from 10 nm to 14 nm. Intel is still plagued by production problems in 10 nm manufacturing. Since Zen 2, AMD no longer relies on in-house production at Globalfoundries, but now has its processors manufactured by TSMC in Taiwan. The Zen 3 processors are manufactured in 7 nm, but TSMC already has a 5 nm node, which, however, has been completely reserved by Apple. Only AMD's Zen 4 processors are also manufactured at TSMC in 5 nm.

Since both processors have 8 CPU cores and support Hyper-Threading or Simultaneous Multi-Threading, 16 threads can be processed in parallel by the CPUs. Intel is limited to 8 cores at Rocket Lake, while AMD has significantly larger expansion levels on offer with the AMD Ryzen 9 5900X (12 cores, 24 threads) and the AMD Ryzen 9 5950X (16 cores, 32 threads).

The rivals are also very similar when it comes to RAM: 128 GB DDR4-3200 memory in two memory channels (max. 4 modules) are supported. Due to the smaller manufacturing density, AMD can give the AMD Ryzen 7 5800X 32 MB Level 3 cache, while the Intel Core i7-11700K has to get by with 16 MB.
