The difference with CPU mining vs GPU mining

Different Coins/Protocols Optimized For Or Compatible With CPUs

With Salad, we use your CPU power to mine for Monero via XMRig. It’s one of the most reliable and profitable coins for CPUs to mine.

Highly Variable Earning Rates And Lower Hashing Power

There are several factors that affect your CPU’s earning rates while mining, of course - many of these are identical to GPU mining, like:

If you’re unfamiliar with any of these, we’d highly recommend that you read our beginner’s guide to blockchain to get down the basics. Where CPU mining differs is primarily three variables, these being:

  • Relying on RAM instead of VRAM for Hash rates
  • Elevated sensitivity to background processes and apps
  • Fewer Arithmetic Logic Units (they do less math)

To translate that to English: your CPU doesn’t have its own dedicated RAM like most consumer Graphics Cards. This means it relies entirely on the sticks in your motherboard for support. You may have a badass CPU with 12 cores, hyperthreading, etc - but it won’t do you any good if you only have 2 Gigabytes (GB) of RAM in your PC.

The CPU also has a wider realm of responsibilities than the GPU. Generally speaking, Graphics Cards are only called upon to perform a few specialized processes, like game graphics and particle effects. However, the CPU is the brain of your computer, overseeing everything from your Excel Spreadsheet to Google Chrome tabs. The more background processes you have running, the less spare power your CPU has to contribute towards hashing. This makes CPU mining essentially ineffectual unless you’re truly AFK.

Finally, GPUs are specialists, and CPUs are jack-of-all-trades. Typically, this is a good thing - as we said, CPUs are asked to do a lot of different tasks and need a wide skill set. Sadly, the type of tasks required for mining, highly parallelized computations, is where the GPU shines. A CPU generally will not be able to put out the same kind of raw hash power that a GPU can produce, and this will reflect in earning rates.
