What CPU and GPU for Bitcoin mining still make sense in 2025? And is it even profitable to use them? With Bitcoin mining now dominated by powerful ASIC (Application-Specific Integrated Circuit) machines, many newcomers wonder whether mining with consumer-grade CPUs and GPUs is still viable. Spoiler: for Bitcoin itself, not really—but there are important nuances to consider.
Can You Still Mine Bitcoin With a CPU or GPU?
Technically, yes. Practically, no. In Bitcoin's early days (circa 2009–2011), mining with CPUs and later GPUs was common. But as competition grew, ASICs—hardware designed solely to mine Bitcoin—took over due to their vastly superior hash power and energy efficiency.
Today:
CPU mining for Bitcoin is obsolete.
GPU mining for Bitcoin is also ineffective.
Modern Bitcoin mining now requires ASIC miners like the Antminer S21 or WhatsMiner M60 series.
What CPUs and GPUs Are Best for Altcoin Mining?
While CPUs and GPUs aren't viable for Bitcoin, they can still mine other Proof-of-Work (PoW) cryptocurrencies:
CPU Mining: Coins like Monero (XMR) still favor CPUs due to their RandomX algorithm.
Best CPUs: AMD Ryzen 9 7950X, Intel Core i9-13900K
GPU Mining: Ethereum no longer uses PoW, but coins like Ravencoin (RVN), Ergo (ERG), and Kaspa (KAS) are still GPU-friendly.
Best GPUs: NVIDIA RTX 4090. AMD RX 7900 XTX, NVIDIA RTX 3080 Ti
These setups can be profitable depending on power costs, network difficulty, and token price.
Is Bitcoin Mining Still Profitable at Home?
Only if you're using a modern ASIC with cheap electricity. Consider:
Antminer S21: ~200 TH/s with ~17.5 J/TH efficiency
Electricity rate: Below $0.07/kWh is usually the breakeven point
Mining pools: Most solo miners now join pools like Foundry USA or F2Pool for consistent payouts
Using a GPU to mine Bitcoin directly would yield near-zero results and waste electricity.
Should You Mine Bitcoin or Just Buy It?
For most individuals, buying Bitcoin is far more practical than mining it. However, some still mine for:
Passive income (via ASIC farms)
Heating purposes (repurposing heat from miners)
Network support or hobbyist interest
But CPUs and GPUs are better saved for altcoins if you want a shot at profitability.
Conclusion
So, what CPU and GPU for Bitcoin mining are best? The honest answer: none. Bitcoin mining is now the domain of specialized ASIC hardware. If you're interested in mining with CPUs or GPUs, explore altcoins like Monero or Ravencoin instead. Always factor in electricity costs, hardware ROI, and network trends before investing. For direct Bitcoin exposure, it might be smarter—and cheaper—to simply buy and hold.
