Mega-Chips Without Power? AI Comes to a Standstill Without AMD, Nvidia, Infineon and NU E Power

AMD and Nvidia: The Little Brother Strikes Back

Given the existing physical limits of the energy supply, chip developers are now also under enormous pressure to innovate and are countering these challenges with technological solutions. They are relying on highly specialized AI architectures (ASICs) and state-of-the-art semiconductor manufacturing at the 3-nanometer scale and smaller to drastically increase efficiency per watt. Through advanced packaging in 3D chiplet design and ultra-compact High Bandwidth Memory (HBM), they are shortening signal paths, resolving the energy-intensive data bottleneck between the processor and memory, and specifically optimizing layouts for power-efficient liquid cooling.

Just how urgently needed this radical shift in thinking about energy efficiency is was underscored by the record figures released by the global AI market leader this week. Nvidia once again shattered all Wall Street estimates with phenomenal quarterly revenue of USD 96.22 billion—more than double the previous year's figure. The data center segment remains the driver of this astronomical expansion, generating record revenue of USD 89 billion on its own, underscoring the fundamental importance of physical computing power. Yet even the industry leader is feeling the physical limits of the boom, as management acknowledged that ongoing supply bottlenecks for advanced memory components will cap growth in the coming year. Nevertheless, the stock rose by a solid 8% to USD 226, gradually approaching the 12-month average target of USD 331 on the LSEG Refinitiv platform. Nvidia's numbers are slowly becoming a bull-market phenomenon on the NASDAQ, with Olympic-like momentum.

Competitor AMD, which had previously reported strong data center growth with quarterly revenue of USD 11.5 billion, notes in its outlook that the greatest risk in the technology sector currently lies not on the demand side but in the physical feasibility of the infrastructure. For investors, these latest market movements underscore that while the train is running at full steam, even the smallest setbacks could bring down the sector's enormous valuations.

Infineon: German Engineering Expertise Is Also in Demand

While US giants design the computing cores, German semiconductor specialist Infineon supplies the essential power electronics needed to make the immense energy demands of AI infrastructure manageable in the first place. With groundbreaking wide-bandgap semiconductors made of silicon carbide and gallium nitride, the company minimizes the massive power losses during the transformation from the high-voltage grid directly into the chip. To route the enormous currents of modern graphics processors more efficiently, Infineon relies on revolutionary Vertical Power Delivery (VPD). By placing the voltage regulators directly beneath the computing core, the physical line resistance is drastically reduced, minimizing heat loss and significantly lowering cooling requirements. This strategic focus is underpinned by the brand-new acquisition of the specialist firm C2i Semiconductors, through which Infineon is massively expanding its expertise in intelligent, software-defined power management. In addition, the DAX-listed company is collaborating directly with NVIDIA to establish novel DC power infrastructures for megawatt-class server racks. For forward-looking investors, Infineon is positioning itself as the indispensable backbone of efficiency for the global AI boom. If analysts on the LSEG Refinitiv platform are to be believed, the Munich-based company could rise another 50% from its current price of EUR 56 to EUR 87 over the next 12 months. Well then!

NU E Power: Energy Infrastructure Is the Next Bottleneck

Staying with the topic of energy efficiency: Canadian company NU E Power (NUE) is also active in the energy market, pursuing an interesting business model. The company acts as an accelerator for energy projects that will increasingly be needed in regions where electricity becomes the scarcest production factor. NU E Power identifies and secures suitable sites at an early stage and increases their value through permitting, grid connections and offtake agreements before a project is either sold, developed with partners or held in its portfolio over the long term. It is precisely this early development phase that serves as the key value driver for NU E Power, because major infrastructure investors typically do not get involved until technical and regulatory risks have been largely eliminated.

This is supported by a recent IEA analysis, which projects that global electricity consumption by data centers will rise to approximately 945 TWh by 2030—more than doubling compared to 2024. The proposed Hays transaction in southern Alberta demonstrates how the company intends to translate this structural trend into assets, as the planned acquisition of three project companies would give NU E Power full control over a solar and battery storage site for the first time. Hays comprises approximately 145 MWac of solar capacity, as well as a planned storage facility with 61.5 MW or 123 MWh, which, on completion of the transaction, would increase the portfolio from 1,112.25 MW gross and 613.94 MW net to approximately 1,258 MW gross and 760 MW net. The key point, however, lies less in the sheer megawatt figure than in the transaction structure. The purchase price is an estimated CAD 7.25 million and can change if the final approved solar capacity differs from the 145 MWac currently contemplated. CAD 100,000 is payable at closing and is credited against the Notice to Proceed payment. Seventy per cent of the remaining balance is payable on Notice to Proceed, and the final thirty per cent on the Commercial Operation Date. In doing so, NU E Power is consistently following its "develop-to-divest" approach and shifting a large portion of the capital investment to those project phases in which substantial value appreciation has already been achieved.

At the same time, the combination of solar and battery storage creates additional flexibility, as generated electricity can be time-shifted and thus better aligned with the demand of large industrial and data center customers. The recent expansion of the management team aligns perfectly with this next step in the company's development. Effective August 31, John Windsor will assume the position of COO. He brings more than 20 years of experience in operating large power portfolios and has held positions at Algonquin Power & Utilities, Northland Power, and Emera, among others. At Algonquin, Windsor was at times responsible for 3,200 MW spread across 56 individual projects, bringing precisely the operational experience NU E Power needs as it transitions from project acquisition to permitting, grid connection, and construction readiness.

It is important to note: The focus is not on building a single power plant, but on controlling sites where grid capacity, generation, and large-scale consumers can be brought together. Upon completion of the Hays transaction, this would be the company's first wholly owned project and its first integrated solar and storage asset, while the existing portfolio already comprises 1,112.25 MW gross capacity (613.94 MW net). For now, the investment case remains clearly development-driven, as Hays currently has neither a final grid connection agreement nor a power purchase agreement. The LOI is non-binding, and completion of the acquisition remains subject to seven conditions precedent. NU E Power is making good progress in the "alternative energy" segment and is tapping into the spirit of the energy transition.

Analysts are already speculating about the major economic effects of AI being deployed across businesses. But you do not have to be a prophet to predict the outcome. Once the initial implementation costs have been absorbed and the technology reaches maturity, it will eliminate millions of jobs. The key to sustainable success, however, appears to be energy infrastructure—an area investors are currently paying far too little attention to.
