How to Choose the Right Intel CPUs for Mining

When choosing the best Intel CPUs for mining, you have to consider following factors

Power Consumption

Mining cryptocurrencies is a process that needs a lot of energy to run. A power hungry processor will add more bucks to your bills as compared to a processor with lower TDP. For mining, Intel Celeron processors use low power (less than 60W) to power your mining rig.

Although Celerons come with just two cores and threads to mine out the coins, still they outshine in the mining industry. Intel Pentium processors are cheap as compared to Intel Core Series processors. Therefore, beginners can start their mining journey with processors like Intel Pentium G4400.

Price

Whenever you choose a CPU for mining, make sure you go for a cheaper one. This will allow you to save money for most important components of a mining rig like graphics card, rams and power supply. However, choosing a cheap CPU for mining does not mean that you should go for a single-core CPU.

Cores

For mining, you must go for a CPU with at least 2 cores. However, make sure you choose a CPU with more cores and low TDP. We recommend you stick with at least 4 cores if you want decent performance.

L3 Cache

L3 cache is the most crucial factor to consider when buying a CPU for mining. As the algorithm used for mining has a buffer size of 2 MB, therefore, the mining performance of the CPU depends upon the times a buffer can fit into the cache. Therefore, higher the number of cache, faster will be the mining process.

The Bottom Line

With some of the best processors from Intel, CPU mining has caught the attention of many crypto miners. If you are a beginner and low on budget, then we recommend you to stick with Pentium G4400 CPU due to its low power and price. For advanced crypto mining, the Intel Core-i7-8700K might be the final bet. It holds more power, cache, and cores as compared to other CPUs on our comparison chart.
