Cryptocurrency mining has evolved significantly since the early days of Bitcoin, but one component remains foundational—the CPU. While GPUs dominate headlines for high-speed mining, central processing units (CPUs) still offer a cost-effective, accessible entry point into the world of crypto mining. Especially with newer privacy-focused and CPU-friendly blockchains emerging, mining with your processor is more viable than ever.
This guide explores the top 5 CPUs for cryptocurrency mining in 2020, focusing on performance, efficiency, and compatibility with profitable mining algorithms. Whether you're a beginner or a seasoned miner looking to optimize your setup, this breakdown will help you make an informed decision.
What Is CPU Mining, and Is It Still Profitable?
CPU stands for Central Processing Unit, the core brain of any computer. It handles instruction execution, resource allocation, and general computing tasks—including cryptocurrency mining.
While GPU mining often delivers faster hash rates, CPU mining remains relevant for several reasons:
- Lower upfront cost: Most people already own a capable CPU.
- Energy efficiency: CPUs typically consume less power than high-end GPUs.
- Algorithm compatibility: Coins like Monero (XMR) use CPU-optimized algorithms (e.g., RandomX) that resist ASIC dominance.
- Accessibility: No need for expensive rigs—just a standard PC.
Although solo Bitcoin mining is no longer feasible, altcoins friendly to CPU mining have created new opportunities. Some even ban ASICs and multi-GPU setups, leveling the playing field for individual miners.

The 5 Best CPUs for Mining in 2020
1. AMD Ryzen Threadripper 1950X
Cores: 16
Threads: 32
Base Clock: 3.4 GHz
Boost Clock: 4.0 GHz
Compatible Coins: Monero (XMR), Epic Cash (EPIC), Electronium (ETN), Ravencoin (RVN), Zcash (ZEC)
The AMD Ryzen Threadripper 1950X stands as a powerhouse in CPU mining. With 16 cores and 32 threads, it excels at parallel processing—ideal for mining algorithms that leverage multi-threading.
Its 32MB L3 cache enhances data access speed, boosting mining efficiency. While it's one of the pricier options on this list, its performance justifies the cost for serious miners.
However, if you're just starting out, consider beginning with a more budget-friendly option and upgrading later. The 1950X is best suited for those building a dedicated mining rig or seeking maximum output from day one.
2. AMD Ryzen Threadripper 1920X
Cores: 12
Threads: 24
Base Clock: 3.5 GHz
Boost Clock: 4.0 GHz
Compatible Coins: Monero (XMR), Epic Cash (EPIC), Electronium (ETN), Ravencoin (RVN), Zcash (ZEC)
A step down from the 1950X but still a beast in its own right, the Threadripper 1920X offers excellent value. With 12 cores and 24 threads, it maintains strong multi-threaded performance while being significantly more affordable.
It shares the same 32MB L3 cache as its bigger sibling, ensuring fast data retrieval during mining operations. This CPU strikes a smart balance between cost, power consumption, and processing speed—making it ideal for both beginners and experienced miners.
For those entering the space without breaking the bank, this is a top-tier choice.
3. AMD Ryzen 5 1600X
Cores: 6
Threads: 12
Base Clock: 3.6 GHz
Boost Clock: 4.0 GHz
Compatible Coins: Monero (XMR), Epic Cash (EPIC), Electronium (ETN), Ravencoin (RVN), Zcash (ZEC)
Don’t let its mid-range status fool you—the Ryzen 5 1600X packs a punch for its price. With 6 cores and 12 threads, it delivers solid performance for entry-level mining setups.
It’s particularly effective for coins using memory-hard or multi-threaded algorithms. While not as powerful as the Threadripper models, its lower cost and energy consumption make it perfect for hobbyists or secondary mining machines.
This CPU also offers great potential for overclocking, allowing users to squeeze out extra performance without additional investment.

4. Intel Core i5-7600K
Cores: 4
Threads: 4
Base Clock: 3.8 GHz
Boost Clock: 4.2 GHz
Compatible Coins: Monero (XMR), Epic Cash (EPIC), Electronium (ETN), Ravencoin (RVN), Zcash (ZEC)
Here’s where Intel enters the scene. The Core i5-7600K has fewer cores and threads compared to AMD counterparts, but it makes up for it in per-core performance and overclocking flexibility.
With a base clock of 3.8 GHz, it starts strong and can be pushed further with proper cooling. While not ideal for highly parallelized mining workloads, it performs well on algorithms that benefit from high single-thread speeds.
It’s also a solid dual-purpose chip—excellent for gaming and light mining simultaneously. If you want a PC that doubles as a miner without sacrificing everyday usability, this is a smart pick.
5. Intel Core i7-9700K
Cores: 8
Threads: 8
Base Clock: 3.6 GHz
Boost Clock: 4.9 GHz
Compatible Coins: Monero (XMR), Epic Cash (EPIC), Electronium (ETN), Ravencoin (RVN), Zcash (ZEC)
The i7-9700K outperforms the i5-7600K with double the cores and higher boost clocks, making it one of Intel’s strongest consumer CPUs for mining.
Its 4.9 GHz turbo frequency ensures rapid processing, especially beneficial for latency-sensitive tasks. However, it lacks hyperthreading (only 8 threads), which limits its edge over AMD in heavily multi-threaded environments.
Still, for hybrid use cases—gaming, streaming, and moderate mining—it remains a compelling option. Just be mindful of heat output and power draw when running extended mining sessions.
Frequently Asked Questions (FAQ)
Q: Can I mine cryptocurrency with just my CPU?
Yes, especially with coins like Monero (XMR) that use CPU-optimized algorithms such as RandomX. These are designed to prevent ASIC dominance and keep mining decentralized.
Q: Is CPU mining still profitable in 2020?
It can be, depending on electricity costs, coin value, and hardware efficiency. While not as fast as GPU or ASIC mining, CPU mining offers low entry barriers and works well for privacy coins.
Q: Which cryptocurrency is best for CPU mining?
Monero (XMR) is the most popular and profitable CPU-mineable coin due to its focus on privacy and resistance to specialized hardware.
Q: Do I need a dedicated rig for CPU mining?
Not necessarily. You can start mining on your existing PC, though dedicated rigs improve uptime and efficiency.
Q: Should I choose AMD or Intel for mining?
AMD generally wins in multi-threaded performance due to higher core/thread counts, making it better for parallel mining tasks. Intel excels in single-thread speed and overclocking—ideal for mixed-use systems.
Q: Can I overclock my CPU for better mining performance?
Yes, but ensure adequate cooling and monitor stability. Overclocking increases power consumption and heat, which may affect long-term reliability.
