Monero Hashrate kH/s

Processors for mining should be the most modern and effective. There are no specific models that are created specifically for mining. Just evaluate CPU performance in cryptocurrency mining XMR (Monero). As a general rule of thumb, most experts advise one to spend as little as possible for CPU and RAM on a mining rig. Also consider the following: - What is the best CPU for cryptocurrency mining? - What is mining on a CPU? - What is a processor in crypto mining? - Is it worth it to mine with CPU? Generally, a processor can thread up to twice its base amount. For example, a 4 core processor can produce up to 8 threads on average.
