Performance and technical specifications of the Intel Celeron G1840 processor
The Intel Celeron G1840 is part of the entry-level processor lineup, but don’t let its simplicity deceive you. With a clock speed of 2.8 GHz and two physical cores, this processor is based on the Haswell architecture, which has proven to be very stable over time. Its 22 nm manufacturing process contributes to reduced power consumption, a key criterion for mining where thermal management is crucial.
Here are the key features that make the G1840 a wise choice:
- Number of cores: 2 cores present, without hyper-threading.
- Operating frequency: Stability at 2.8 GHz, ensuring consistent performance.
- L3 Cache: 2 MB, sufficient to support secondary tasks related to mining such as non-graphical computations.
- Power consumption (TDP): 53 W, meaning low power consumption compared to more powerful CPUs.
- Socket: Compatible with LGA 1150 sockets, commonly used on budget motherboards that integrate multiple PCIe slots for effective GPU connections.
Cryptocurrency mining, especially with algorithms such as Ethash (Ethereum) or Equihash (Zcash), relies heavily on GPU power. Nevertheless, the processor plays a crucial role in managing and controlling the rig, starting tasks, and communicating with the blockchain. The Celeron G1840 thus perfectly balances necessary performance and energy savings to ensure continuous operation 24/7.
A comparative table outlining the performance of the G1840 against other CPUs frequently recommended for mining illustrates this positioning:
| Processor | Cores / Threads | Frequency (GHz) | L3 Cache (MB) | TDP (W) | Recommended mining usage |
|---|---|---|---|---|---|
| Intel Celeron G1840 | 2 / 2 | 2.8 | 2 | 53 | Budget mining rig |
| Intel Pentium Gold G6400 | 2 / 4 | 4.0 | 4 | 54 | Mid-range configurations |
| AMD Ryzen 3 3100 | 4 / 4 | 3.6 | 16 | 65 | Versatile rigs |
| Intel Core i9-10900X | 10 / 20 | 3.7 | 19.25 | 165 | Expensive high-performance rigs |
This table illustrates that the Celeron G1840, despite its modesty, offers controlled energy consumption, sufficient for the efficient management of a rig with 6 GPUs, which is the configuration often recommended for optimizing return on investment.
Financial advantages and energy efficiency of the Intel Celeron G1840 in cryptocurrency mining
The initial cost and energy expenditure are critical factors in cryptocurrency mining. A poorly calculated expense can quickly cancel out all profits from a rig. This is where the Intel Celeron G1840 particularly shines.
Indeed, this processor has an attractive purchase price in the second-hand or new markets aimed at affordable mining configurations. Beginner miners or those looking to develop a mining farm on a budget often choose this key component for its excellent cost / performance / consumption ratio.
Here are a few arguments to better understand this financial advantage:
- Accessible price: The G1840 is often available at a price below 50 euros, a considerable asset compared to high-end processors exceeding several hundred euros.
- Reduced consumption: With only 53 W of TDP, it minimizes overall electrical load, which is crucial as electricity often accounts for more than 60% of operating costs.
- Heat reduction: Less energy consumed means less heat generated, extending the life of rig components and reducing cooling needs.
- Facilitated maintenance: Less overheating and a proven architecture result in a lower failure rate, ensuring stability and continuity of mining.
- Compatibility with cheap motherboards: Motherboards equipped with the LGA 1150 socket are very affordable, multiplying the PCIe ports essential for connecting GPUs.
A simple calculation model allows visualization of these savings in a real-world context:
| Item | Intel Celeron G1840 | High-end Processor |
|---|---|---|
| Purchase price (€) | 45 | 350 |
| Consumption (W) | 53 | 150 |
| Electricity cost/year (€) | 50 (estimate) | 140 (estimate) |
| Maintenance (€) | 15 (less frequent) | 40 (more intensive) |
| Total expenses 1 year (€) | 110 | 530 |
This estimate illustrates how using an Intel Celeron G1840 in a mining rig can significantly improve gross profitability, provided that its configuration is adapted to the practical requirements of mining.
Finally, in 2025, energy optimization is also a significant argument from an ecological and legislative perspective. This trend continues with recommendations aimed at limiting the consumption of mining farms, particularly in Europe, thus increasing interest in low-energy-consuming hardware like this processor.
Stability and compatibility: decisive criteria for reliable mining
Stability is an absolutely fundamental requirement in the cryptocurrency mining sector. Operating often 24 hours a day, seven days a week, rigs require hardware capable of maintaining performance without interruptions or systematic crashes. The Intel Celeron G1840 excels in this area thanks to:
- A proven architecture: Based on Intel’s Haswell generation, this CPU is known for its robustness and longevity.
- Moderate temperature management: The low TDP minimizes overheating risks, allowing for continuous operation without rapid deterioration.
- Strong compatibility: The LGA 1150 socket provides extensive compatibility with a wide range of mining-friendly motherboards, particularly those equipped with multiple PCIe slots.
- Mature technical support: The BIOS, drivers, and firmwares for this range are widely stabilized, reducing hardware and software conflicts.
- Secure software environment: Whether it’s Windows 11, Linux Ubuntu, or HiveOS, the Celeron G1840 enjoys perfect compatibility with OSs dedicated to mining.
This means that rigs based on this processor encounter fewer incidents, reducing downtime and maximizing yield. Practically, this translates to:
- Fewer unexpected restarts

| Durability under 24/7 load | Excellent | Variable |
Choosing a stable and compatible processor ensures a better user experience, especially for beginners. This allows one to focus entirely on optimizing GPU performance, the real engine of mining.
How to build an optimal mining rig around the Intel Celeron G1840
Correctly assembling your mining rig is a key step to avoid disappointments and optimize your return on investment. The Intel Celeron G1840, thanks to its low consumption and its popular socket, makes this operation easier.
Here’s a structured and comprehensive method for building a performing rig around this processor:
Choose a suitable motherboard
The motherboard must be compatible with the LGA 1150 socket and offer a sufficient number of PCIe ports, at least six, to connect all graphics cards. Models like the Asrock H81 Pro BTC or the Gigabyte GA-H81-D3 are reputable and affordable. They provide the stability and compatibility sought without breaking the budget.
Select RAM
The rig requires few CPU resources; 4 GB of DDR3 RAM is generally sufficient to ensure smooth management of mining applications. In the case of heavier rigs, 8 GB allows for comfortable leeway. It’s better to prioritize high-frequency modules to avoid potential slowdowns during system startup.
Install an SSD
An SSD of at least 64 GB ensures a quick system boot, especially if you choose a mining-dedicated OS like HiveOS or Ubuntu. This space is also important if you manage multiple partitions or store additional applications. The SSD should be SATA-compatible to match classic LGA 1150 motherboards.
Efficient power supply
A power supply certified 80 PLUS Bronze or better (Gold, Platinum) is essential. It should be sized between 800 W and 1200 W based on the number of GPUs. In the case of 6 cards, 1000 W is a reliable average. Choosing a modular power supply simplifies cable management and improves airflow inside the rig.
Cooling and structure
Thermal management is critical. Install quality fans to exhaust hot air from the GPUs and prevent overheating. Choose either reinforced aluminum structures or dedicated mining racks to ensure good airflow. A cool and less dusty location remains essential.
Peripherals and initial setup
- A keyboard, basic mouse, and monitor are necessary for startup and configuration.
- Install an external push button to turn on the rig without a traditional case.
- Plan a PCIe riser cable kit to ensure proper connections for the graphics cards.
- Install a wattmeter to monitor the rig’s overall consumption in real-time.
Once the hardware is assembled, the software configuration with HiveOS or Ubuntu allows launching mining applications, monitoring performance, and adjusting settings to maximize profitability.
| Component | Recommended specification | Role in the rig |
|---|---|---|
| Processor Intel Celeron G1840 | Socket LGA 1150, 2 cores, 2.8 GHz | Operation control, GPU management |
