With the widespread expansion of AI applications, the computational power required to train and deploy these complex models is also rising dramatically. This trend has led to rising capital expenditures (CapEx) and operating expenditures (OpEx) for data centers, a key building block underpinning the digital revolution.
Artificial intelligence (AI) has become a core force driving global technological change, and it shows great potential in many fields such as healthcare, finance, automotive and entertainment. But as AI applications have expanded widely, the amount of computational power required to train and deploy these complex models has skyrocketed. This trend has led to rising capital expenditures (CapEx) and operating expenditures (OpEx) for data centers, a key building block underpinning the digital revolution.
Faced with the challenge of rising costs, many data center owners have adopted a strategy of spreading the cost of the inference phase through amortization of AI training equipment, for example, deploying AI models that have already been trained. While this approach may seem to reduce financial pressure in the short term, there are hidden risks that can adversely affect the financial health and operational efficiency of the data center. In order to drive the continued healthy development of AI, we must adjust our strategy - seeking to balance capital investment and operating expenses while ensuring the long-term stability and efficient operation of equipment.
Current strategy: Amortization and cost sharing
Amortizing the cost of AI training hardware over its expected lifetime is relatively straightforward. Given the high demand for computing resources for AI training, the acquisition cost of high-end Gpus and accelerators can run into millions of dollars. By spreading these high costs over several years, data center owners are trying to justify this huge investment and ensure that high-end training equipment is economically viable.
These expensive pieces of hardware are not left idle after the training task is completed, they are often turned over to reasoning work after the training phase is over. The idea is that if data centers can leverage the same set of hardware for both training and inference, the resulting total revenue will help offset the initial equipment investment and ongoing power consumption. In theory, the logic makes sense: spreading investment costs across a variety of operating activities reduces pressure on financial metrics, potentially boosting profitability.
The real culprit in operating costs: electricity consumption
While training equipment is a key capital investment, power consumption is a major component of operating costs in a data center, especially during training and reasoning. High-performance Gpus and accelerators generate a lot of heat while running and require a powerful cooling system to maintain it, which not only causes a surge in electricity bills, but also puts pressure on electric utilities. Even with cutting-edge cooling technology and energy-saving measures, the power demand for running AI on a large scale remains difficult to effectively control.
The problem becomes more apparent when data centers use high-powered training equipment for long inference tasks. Unlike training, which is usually abrupt and possibly intermittent, inference tasks are continuous because the model needs to process a real-time stream of data. Constant workloads mean that these high-capacity systems need to operate near full capacity for long periods of time, resulting in operating costs that far exceed expectations.
Hidden operating cost culprit: Delays
In the field of hardware processing, latency is a factor that is often overlooked but has a significant impact. Latency refers to the time between initiating a query and getting a response. In the training phase of machine learning, delays are generally tolerated, but in the reasoning phase, the situation is completely different. At this stage, even a small delay can set off a chain reaction. If the response time is longer than a few seconds, it can lead to decreased user engagement, harm the user experience, and defeat the purpose of real-time processing.
To overcome latency issues, engineers may consider increasing the number of processors to enable parallel processing, thereby boosting overall processing power. At first glance, this approach seems to work; After all, adding more processors directly increases processing speed. But in reality, the problem is more complicated than imagined. Adding processors does improve performance, but it comes at a significant cost: data center operators' CAPex and OPEX will increase dramatically. Adding hardware resources is like adding fuel to the fire, and while it may alleviate the latency problem for the time being, it may also cause costs to increase so dramatically that they become unsustainable.
The increase in cost is not only reflected in the initial investment, but also leads to an increase in the daily operating budget, which in turn increases the demand for electricity consumption, maintenance costs and resource management. For many businesses, this practice can become a heavy operational burden, and the negative impact can outweigh the benefits of reduced latency. In the face of this challenge, organizations need to adopt more efficient and sustainable strategies to address latency issues, such as through specialized hardware optimization, smarter data processing architectures, or leveraging technologies that simplify real-time response without breaking budgets.
Equipment depreciation and life challenges
A major problem with the current amortization strategy is that it presupposes that AI training equipment will last long enough to fully depreciate when it is converted to inference tasks. Although these devices do have powerful processing power, the wear and tear caused by prolonged continuous use can be very serious.
Ai hardware that is used to the limit during the training phase may not be as durable as expected when performing reasoning tasks on an ongoing basis. One reality that cannot be ignored is that many data centers may have to replace these systems before they are depreciated, which not only results in an early write-off of capital, but also an additional financial burden.
Seek sustainable solutions
In the face of these challenges, the industry must explore sustainable solutions, finding a balance between capex and OPex to ensure that investments in AI infrastructure are not only justified in the short term, but also durable and efficient in the long term. At this point, innovative designs that focus on long-term stability and energy efficiency are particularly important.
One possible solution comes from an industry that doesn't seem to have anything to do with data centers: the automotive industry. Automotive-grade technology has long been committed to creating durable, stable and energy efficient products. Unlike traditional data center hardware, automotive-grade systems are designed to withstand harsh environments and long periods of continuous operation without significant performance degradation. This tough property means longer service life and reduced replacement frequency, which becomes a crucial advantage when considering equipment amortization.
The automobile grade method is adopted
An innovative company that started out serving the automotive industry has developed a technology that could reshape the way data centers stratege about artificial intelligence. Using stringent quality and durability standards tailored to the automotive industry, automotive-grade solutions offer several advantages that are highly matched to the needs of the data center.
First, these systems are designed with low power consumption in mind. Unlike many high-end Gpus and AI accelerators with high power consumption, this technology prioritizes energy efficiency while maintaining superior performance. This effectively solves the main operating cost problem caused by power consumption when running a large number of AI models, thus significantly reducing the overall operating cost.
Second, this type of solution has a longer service life than traditional AI training hardware. Equipment with automotive-grade durability can withstand the harsh environments of continuous use and is less prone to early wear and damage than traditional data center hardware. This means longer depreciation cycles and reduced capital investment in new hardware, effectively reducing financial pressure on data center operators.
Rethinking AI strategy
The development of artificial intelligence continues unabated, and the demand for data centers to support its growth is also rising. The strategy of diverting expensive training equipment to reasoning tasks to spread the cost is increasingly revealing its shortsighted nature, failing to adequately consider the practical implications of power consumption and hardware lifetime. To avoid unsustainable financial and operational pressures, the strategy must be adjusted.
Incorporating automotive-grade technology solutions into AI infrastructure planning can bring much-needed improvements. While these systems may require an initial recalibration of budgets to account for higher capital expenditures, the long-term benefits - reduced energy consumption, extended equipment life, and more reasonable amortization arrangements - will far outweigh the initial investment costs.
Final thought
As the data center continues to drive the AI revolution, industry leaders must re-examine strategies to address the hidden costs of AI at scale. The current practice of amortizing the cost of training equipment through sharing in the inference phase ignores key operational cost challenges and practical issues of hardware service life.
By adopting solutions that focus on efficiency and durability, data centers can build a more sustainable and cost-effective building block for the future of AI. The future development path requires not only innovation in AI models, but also innovation in the infrastructure that supports AI operations.
