Key takeaways:
- nVIDIA continues to deliver enhanced AI performance, speed and reduced energy consumption.
- Data centre REITs are benefiting from strong demand as a result of rising data centre infrastructure growth and spending.
- Tech and property companies are partnering up, creating multiple growth pathways to meet growing genAI demand.
With generative AI (genAI) still in its infancy, there are wide ranging and exciting existing and new use cases spurring increasing demand and investment from corporates and governments. However, all of this needs AI infrastructure – the hardware (eg GPUs, servers, data storage) and software (programming languages, platforms, tools). Equally as important, are the data centres to house the servers, requiring large amounts of energy to power and cool them. The firms behind these critical AI enablers are partnering with each other in the race to harness the benefits of AI.
The tech view (Richard)
nVIDIA’s recent GTC event in San Jose was taglined ‘the conference for the era of AI’ and it did not disappoint, with a huge swathe of innovation announced. The centrepiece was the launch of the next-generation chip architecture – Blackwell – named after the first Afro-American mathematician to be inducted into the National Academy of Sciences. The new chip boasts a mammoth 208 billion transistors compared to its predecessor’s 80 billion,1 but achieves this by stitching together two separate GPU dies given the size of each die has reached the physical reticle limit of an ASML lithography tool (the maximum size that a lithography tool can etch to build a chip).
nVIDIA continues to challenge the fading of Moore’s Law via innovative advanced packaging as well as significantly leveraging higher bandwidth memory. However, the company believes that the colossal complexity of generative AI can only be tackled via a full stack solution. This pulls together nVIDIA’s proprietary high-performance networking and interconnectors such as NVLink, as well as software with a second-generation transformer engine that enables large language models to be trained and inferenced with lower precision calculations. This capability significantly accelerates performance as well as reduces power consumption.
At GTC, nVIDIA took this full stack solution to the next level by unveiling the GB200 NVL72 (a server and workstation that uses GPGPUs to accelerate deep learning applications). Traditionally, nVIDIA has sold boards comprising eight GPUs, but the new product is a full rack solution comprising 72 GPUs as well as 36 Grace Hopper ARM CPUs – all interconnected via thousands of NVLinks. This solution delivers unprecedented compute power, enabling a trillion-parameter large language model (LLM) to be trained 4x faster using only 25% of the power compared to an nVIDIA H100 Tensor Core GPU. More impressively, AI inferencing can be done 30x faster. The sheer horsepower of compute consumes a lot of power but nVIDIA is transitioning from air to liquid cooling. This enables the rack to increase its compute density without overheating, reducing the floor space required, which is a key driver of overall power consumption in data centres. Compared to a H100 air-cooled infrastructure, a GB200 can deliver 25x the performance at the same power while also reducing water consumption.
nVIDIA recently revealed that demand from sovereigns (governments) was as large as the largest three hyperscalers combined. This is a key driver of why nVIDIA’s CEO believes that the current installed base of data centre infrastructure of US$1 trillion can grow to US$2 trillion in the next four to five years, with annual data centre infrastructure spending growing from US$250 billion to US$500 billion in the longer term.2 The full server rack offering from the GB200 NVL72 is currently the ideal solution for sovereigns that lack the technological capability to design their own AI training or inferencing clusters, and are more willing to buy off-the-shelf.
The property view (Guy)
The growth of AI and machine learning applications, which require substantial computational power and data storage, is the latest of many factors driving the need for advanced data centre capabilities from potential tenants. Data centre REITs are seeing surging demand from customers looking to secure their ambitious growth plans in AI and digital infrastructure. In fact, new leasing activity in the US during 2023 totalled the same amount in the entirety of the three years prior (2020-2022).3
Some forecasts for future AI-driven demand growth are staggering: Morgan Stanley forecasted that growth in the public cloud market will surge from US$500 billion+ currently to a US$2.5 trillion opportunity by 2032.4 Boston Consulting Group forecasts that the future demands of AI computing will result in a threefold increase of electricity consumed by data centres by 2030 – this is equivalent to the electricity consumed by a third of US homes in a year.5
Equinix, the world’s largest data centre REIT, is an example of a company that has benefited from the continued growth in data centre demand. Founded 25 years ago, Equinix has developed the world’s most interconnected data centre platform and is a truly global company, with more than half of its revenues generated outside the US. The company also aims to be global climate-neutral by 2030, and has achieved more than 90% renewable energy coverage in recent years.
Equinix recently announced a partnership with nVIDIA to offer the chip firm’s supercomputing systems to corporate clients on an outsourced basis. This makes it easier for Equinix customers to operate “private AI” computing systems allowing for customised use cases and better control over proprietary data, rather than relying on cloud-based computing from the likes of Amazon (AWS) and Microsoft (Azure), which can raise data privacy concerns for some users. nVIDIA has trained Equinix staff to build and run their systems, which will open up a new level of service for Equinix to provide to their tenants – and ultimately a new revenue stream.
We believe this is one example of multiple growth pathways for data centres as the world looks to compete and stay relevant in a rapidly-changing technological era.
In summary
The broadening demand for genAI is creating both opportunities and risks, with potentially significant gains for its key enablers. This, combined with the shift to new technologies to enable a lower power footprint, creates multiple vectors of opportunity for active investors across multiple sectors, including technology and property.
In a follow-up article we will take a deeper dive from a geopolitical and sustainability perspective into how the growth of AI and data centres is fuelling semiconductor trade tensions and the risks from regulatory reform given the insatiable power needs of AI, as well as the implications this has for investors.
These themes are also explored in an upcoming article by the Global Sustainable Equity Team entitled, “Data center boom: Navigating the power crunch.”
