1. Why do you need GPU for Bitcoin?

Unraveling the Role of GPUs in Bitcoin Mining

In the world of digital currencies, Bitcoin has emerged as the undisputed king. Its meteoric rise in value has attracted a multitude of investors and miners, all seeking to tap into its lucrative potential. However, the process of mining Bitcoin is not as straightforward as it seems. It requires a significant amount of computational power, specifically, the power of a Graphics Processing Unit (GPU). But why is a GPU so crucial in Bitcoin mining? Let’s delve into the intricacies of Bitcoin mining and the role of GPUs in this process.

Understanding Bitcoin Mining

Before we delve into the role of GPUs, it’s essential to understand what Bitcoin mining is. Bitcoin mining is the process by which new bitcoins are entered into circulation. It also serves as a mechanism to verify transactions made with the cryptocurrency. This process involves solving complex mathematical problems, which in turn validate transactions and secure the Bitcoin network.

The first miner to solve these problems gets rewarded with a certain amount of bitcoins. However, as more bitcoins are mined, these problems become increasingly complex, requiring more computational power. This is where GPUs come into play.

The Role of GPUs in Bitcoin Mining

A Graphics Processing Unit (GPU) is a powerful processor that’s capable of handling multiple tasks simultaneously. It’s primarily designed to render images in games smoothly, but it’s also incredibly efficient at crunching numbers, which is exactly what’s needed for Bitcoin mining.

In the early days of Bitcoin, mining could be done with a standard Central Processing Unit (CPU). However, as the complexity of the mining process increased, CPUs became less efficient. GPUs, with their ability to perform multiple calculations simultaneously, proved to be more effective for this task.

GPUs can execute thousands of operations at once, making them significantly faster than CPUs at solving the mathematical problems involved in Bitcoin mining. This speed is crucial as the faster the problems are solved, the higher the chances of earning bitcoins.

GPU vs ASIC: The Battle for Bitcoin Mining Supremacy

While GPUs are highly efficient at mining bitcoins, they are not the only hardware used for this purpose. Application-Specific Integrated Circuits (ASICs) are devices designed specifically for Bitcoin mining. They are even more powerful and faster than GPUs, but they come with their own set of drawbacks.

ASICs are expensive and consume a lot of electricity. They are also inflexible, meaning they can only be used for Bitcoin mining. On the other hand, GPUs are more versatile and can be used for other tasks when not mining bitcoins. This versatility, coupled with their relative affordability, makes GPUs a popular choice for many Bitcoin miners.


In conclusion, GPUs play a pivotal role in Bitcoin mining. Their ability to perform multiple calculations simultaneously makes them ideal for solving the complex mathematical problems involved in the mining process. While other hardware like ASICs may offer more power, GPUs provide a balance of efficiency, versatility, and affordability that makes them a popular choice for many miners.

2. AI and Bitcoin Mining Meet in New Texas Data Center

Applied Digital, a blockchain and artificial intelligence (AI) infrastructure provider, has opened its new 200-megawatt (MW) data center in Garden City, Texas.

The facility marks the company’s third blockchain hosting facility to go live in North America.

“Once fully energized, this location will bring Applied Digital to the full planned 480MW of total hosting capacity across its blockchain hosting facilities,” read the company’s announcement on Friday.

A megawatt (MW) is a unit of power equal to one million watts, while a gigawatt (GW) equals one billion watts. Riot Blockchain, another publicly traded Bitcoin miner, boasts a 1GW mining facility in the same state

For context, a standard home light bulb is powered by 60 watts. Meanwhile, Cambridge estimates that the entire Bitcoin network currently demands 14.83 GW, up from its 12.89 GW estimate in September.

Bitcoin miners use such power to produce hashes, which are needed to construct the network’s next block of transactions, for which miners are rewarded with newly minted BTC.

According to Bitinfocharts, Bitcoin’s current hashrate is approximately 400 exahashes per second (EH/s). An exahash equals one quintillion hashes.

“Depending on the model of miners, the facility will support 7-8.5 EH,” Applied Digital Chairman and CEO Wes Cummins told Decrypt.

None of that hashrate is meant for the company itself, however. Cummins said his firm only hosts “other miners,” meaning other companies own the rigs that Allied houses and operates on their behalf. This business allowed Applied Digital to earn $22 million in revenue during the quarter ending in May 2023.

Yet like many mining firms, Applied Digital is turning its focus away from Bitcoin mining and toward high-performance computing (HPC)—another energy-intensive service supporting the AI industry.

3. Bitcoin’s miner reward model raises concerns, says economist

George Mason University economics professor Lawrence White expressed concerns about the changing miner reward model for Bitcoin during a discussion with David Lin published on Sunday. He suggested that as Bitcoin production slows down, miners’ rewards will increasingly depend on transaction fees, potentially leading to security risks caused by insufficient incentives.

At present, miners are primarily incentivized by the generation of new Bitcoins. However, in a future scenario where Bitcoin production ceases, the rewards would solely consist of these transaction fees. This shift could pose significant challenges to the security of Bitcoin transactions, according to White.

Despite these potential risks, White underscored Bitcoin’s robust security history. He emphasized that the cryptocurrency has proven to be hack-proof so far.

While expressing skepticism about Bitcoin’s role as a future currency, White indicated that other cryptocurrencies might be better positioned to fulfill this role.

At the time of their conversation on Sunday, Bitcoin was trading at $29,906.
