Because Malairte is mineable on both CPU and GPU, the processor in your rig is not just a babysitter for the graphics card — it can pull its own weight on the network. That makes CPU selection more interesting than in a GPU-only build, and it rewards understanding what actually drives CPU mining performance.

Why core count is not the whole story

It is tempting to assume the CPU with the most cores wins. For memory-hard, CPU-friendly algorithms, performance is gated as much by cache and memory bandwidth as by raw core count. A processor with a large L3 cache often feeds its cores more effectively than one with more cores but a starved cache.

The numbers that matter

  • Physical cores: more helps, but with diminishing returns once memory bandwidth saturates
  • L3 cache: larger caches reduce trips to main memory and lift memory-hard performance
  • Memory channels and speed: dual-channel at rated speed feeds the cores properly
  • TDP: higher power means more heat and more electricity for the same work

AMD options worth a look

Ryzen chips with large L3 caches, particularly the X3D variants with stacked cache, tend to do well on memory-hard CPU work relative to their core count. A Ryzen 7 with eight cores and a generous cache is a sensible, efficient middle ground for a home rig.

Intel options worth a look

Modern Intel Core processors with a mix of performance and efficiency cores can mine well, but be aware that the efficiency cores contribute differently to the performance cores. For predictable behaviour, many home miners pin work to the performance cores.

Matching the CPU to your goal

If the GPU is doing the heavy lifting and the CPU mostly supports it, a modest six-core chip keeps the system responsive without wasting power. If you genuinely intend to mine hard on the CPU as well, step up to an eight-core part with a large cache and pair it with fast dual-channel memory.

What to avoid

Skip ultra-high-core-count workstation CPUs for a home build. Their power draw and platform cost rarely justify themselves when a mainstream eight-core chip delivers most of the value at a fraction of the heat and electricity. Buy the processor that balances mining contribution against the power bill, not the one with the biggest number on the box.
