Raptoreum cryptocurrency miners cause AMD Ryzen chips shortage due to large L3 cache

 Raptoreum rocked the cryptocurrency world as its mining is optimized for the use of CPU resources, which is welcomed in the ASIC community. The most efficient chips for mining this currency are AMD Ryzen 9 and Threadripper due to the large L3 cache size. As a result, Raptoreum miners have already caused a processor shortage on Amazon.



Initially, the Raptoreum project aimed to end the dominance of ASICs or FPGAs in mining Bitcoin and other cryptocurrencies based on the SHA-256 algorithm. Therefore, the Raptoreum developers switched to CPU mining using the GhostRider algorithm - a combination of Cryptonite and x16r with more intense randomization.


The Ryzen Threadripper and Epyc 7742 processors have the largest L3 cache sizes, but AMD does not produce enough of them, so the Ryzen 9 5000 and 3000 series have become the standard solution. Notably, miners prefer the 12-core model Ryzen 9 3900X over Ryzen 9 3950X or 5950X for a lower price with the same 64MB L3 cache.


The Ryzen 9 3900X and 5900X average around 5100 hash / s. The hashrate can be increased by overclocking, but this does not always make sense, since power consumption also grows with it. Cryptocurrency Raptoreum has already overtaken Monero in mining profitability. AMD is expected to slow down price declines for the foreseeable future as CPU miners drive strong demand.
