現代遊戲PC仍然可以用來開採比特幣嗎？

比特幣加密市場參與者的價格。但是在採礦技術的發展中，出現了一個重要的問題：

The price of Bitcoin crypto has been a hot topic among market participants, especially with the recent surge to new all-time highs above $70,000. But amidst this development and the evolution of mining technology, an important question arises: can modern gaming PCs still be used to mine Bitcoin? The short answer is yes, they can, but not efficiently. Here’s a full review.

比特幣加密貨幣的價格一直是市場參與者的熱門話題，尤其是最近有歷史新高的高度高於70,000美元的新高音。但是，在這種發展和採礦技術的發展中，出現了一個重要的問題：現代遊戲PC仍可以用來開採比特幣嗎？簡短的答案是，他們可以，但不能有效。這是一個完整的評論。

To understand why, let’s delve into the process of mining and the challenges it presents in 2025.

要了解為什麼，讓我們深入研究採礦過程及其在2025年所面臨的挑戰。

What is Bitcoin mining and what are the difficulties?

什麼是比特幣開採，有什麼困難？

Essentially, mining is the procedure of verifying transactions while generating new Bitcoins. The system uses a proof of work (PoW) consensus mechanism, where miners compete to find a valid hash according to the current network difficulty. The first miner to find the hash will receive a reward of 3,125 BTC plus transaction fees.

本質上，採礦是在生成新比特幣時驗證交易的過程。該系統使用工作證明（POW）共識機制，礦工根據當前的網絡難度競爭有效的哈希。第一個發現哈希的礦工將獲得3,125 BTC加上交易費用的獎勵。

However, the mining difficulty in 2025 is very high. It takes an average of 10³¹ hash attempts to generate one valid block. This process consumes a lot of energy – enough to power a US household for more than 10 years. For this reason, the hardware used will determine efficiency and, ultimately, profitability.

但是，2025年的採礦難度很高。它平均需要10³K的嘗試來產生一個有效的塊。這個過程會消耗大量能量 - 足以為美國家庭供電超過10年。因此，所使用的硬件將決定效率，並最終確定盈利能力。

From CPU to ASIC: A brief history of mining devices

從CPU到ASIC：採礦設備的簡短歷史

At its inception in 2009, Bitcoin mining could be done with a regular CPU. As the number of miners increased, the use of GPUs became more common due to their higher capabilities. But when ASICs (application-specific integrated circuits) were introduced, efficiency standards changed drastically.

在2009年成立時，可以使用常規CPU進行比特幣採礦。隨著礦工數量的增加，由於其能力較高，GPU的使用變得更加普遍。但是，當引入了ASIC（特定於應用程序的集成電路）時，效率標準卻發生了巨大變化。

ASICs are designed specifically for mining Bitcoin and are capable of performing tasks much faster and more energy-efficiently than GPUs. Since 2015, ASICs have dominated the mining ecosystem and remain the top choice today. Although modern gaming PCs use GPUs such as the RTX 4090 which is very powerful for gaming, its performance in mining Bitcoin still lags far behind ASICs.

ASIC專為採礦比特幣而設計，並且能夠比GPU更快，更節能地執行任務。自2015年以來，ASIC一直統治著採礦生態系統，並仍然是當今的首選。儘管現代遊戲PC使用GPU，例如RTX 4090，它對遊戲非常強大，但其在採礦比特幣中的性能仍然遠遠落後於ASIC。

Comparing GPU and ASIC performance: An unbalanced scenario

比較GPU和ASIC性能：不平衡的情況

For example, the Nvidia GeForce RTX 4090 can generate hundreds of megahashes per second. Meanwhile, ASICs like the Antminer S21 Pro can generate up to 200 terahashes per second. To put this difference in perspective, it’s a million-fold difference. In addition, the GPU’s power consumption of 450 watts is not economically viable.

例如，NVIDIA GEFORCE RTX 4090每秒可產生數百個兆哈。同時，像Antminer S21 Pro這樣的ASIC可以每秒產生多達200個Terahashes。為了使這種差異在觀點上，這是一百萬倍的差異。此外，GPU的450瓦功耗在經濟上不可行。

In contrast, ASICs are more energy-intensive (around 3,500 watts) but offer much better power-to-yield ratio (around 17.5 joules per terahash). This means that even if you run non-stop mining with a gaming PC, the cost of electricity will far exceed the revenue generated.

相比之下，ASIC的能源更強化（約3500瓦），但提供了更好的功率與收益比（每Terahash約17.5焦耳）。這意味著，即使您使用遊戲PC進行不間斷的採礦，電力成本也將遠遠超過產生的收入。

Economic implications: Investment vs. return

經濟影響：投資與回報

Considering the cost of electricity, maintenance, and possible hardware damage, mining Bitcoin with a gaming PC in 2025 tends to be economically infeasible. The chances of getting a block solo are slim to none. Joining a mining pool is possible, but the small contribution from the GPU means that the revenue received is also minimal.

考慮到電力，維護和可能的硬件損壞的成本，在2025年使用遊戲PC採礦比特幣往往在經濟上是不可行的。獨奏的機會很小。可以加入採礦池，但是GPU的小貢獻意味著收到的收入也很少。

Moreover, GPUs are not designed to run continuously for long periods. Continuous mining can accelerate performance degradation, damage components, and void the device warranty.

此外，GPU的設計不是長期連續運行的。連續採礦可以加速性能降解，損壞組件，並使設備保修無效。

Cryptocurrency alternatives that are still mineable with a gaming PC

仍然可以使用遊戲PC銷售的加密貨幣替代品

While Bitcoin is not ideal for mining with a GPU in 2025, some other cryptocurrencies are still friendly to gaming PCs. These include:

雖然比特幣在2025年與GPU開採並不理想，但其他一些加密貨幣仍然對遊戲PC友好。其中包括：

To determine which crypto is suitable for your device, you can use sites like WhatToMine to simulate potential gains based on your GPU specifications.

為了確定哪種加密貨幣適合您的設備，您可以使用Whattomine之類的站點根據您的GPU規範來模擬潛在的收益。

Conclusion

結論

Technically, a gaming PC can be used to mine Bitcoin, but economically and efficiently, it’s not a wise choice in 2025. With the dominance of ASICs and increasing network difficulty, gaming GPUs are better suited for mining altcoins like Ravencoin or Ethereum Classic. Understanding algorithm characteristics, device efficiency, and operational costs is key in determining whether crypto mining is still relevant for home users in the current market landscape.

從技術上講，遊戲PC可用於開採比特幣，但是​​從經濟和高效上講，它不是2025年的明智選擇。由於ASIC的主導地位和不斷增加的網絡難度，遊戲GPU非常適合Ravencoin或Etherereum Classic等採礦山寨幣。了解算法特徵，設備效率和運營成本是確定加密礦山開採是否仍然與當前市場格局中的家庭用戶相關的關鍵。
