In addition, Nvidia introduced new data center GPU models, the H200 and B100 chips, in the latter half of 2023. The H200 demonstrated double the inference speed of the H100, while the B100 featured 40% more memory capacity than the H200, thanks to the advanced Blackwell architecture.

According to TechInsights, Nvidia held a remarkable 98% share of the data center GPU market in 2023, with shipments reaching 3.76 million units and generating a revenue of $36.2 billion, more than tripling from $10.9 billion in 2022. Furthermore, Trendforce's statistics indicate that Nvidia accounted for 60-70% of the global AI chip market and held over 80% of the worldwide shipment of PC discrete graphics cards.

In contrast to Nvidia's hardware focus, Microsoft stands as a behemoth rooted in software

In the first three quarters of the 2024 fiscal year, Microsoft's segments of productivity and business processes, intelligent cloud, and personal computing accounted for around 31.83%, 42.6%, and 25.58% of the company's revenue, suggesting a more balanced approach than Nvidia.

As per StatCounter, Microsoft's Windows operating system had a dominant 72.72% market share in 2023, considerably outpacing Apple's macOSWithin this ecosystem, Windows 10 held a staggering 67.42% share, while the newer Windows 11 accounted for 26.54%.

This dominant position has resulted in virtually all computers worldwide being inherently tied to Microsoft's operating systemsFor example, after Microsoft announced its plan to end mainstream support for Windows 10 in October 2025, it was estimated by Canalys that at least 240 million devices might be rendered obsolete as a result.

Microsoft's celebrated products extend beyond Windows, with popular offerings such as the Office suite and the Azure cloud platform

By the third quarter of fiscal year 2024, Azure's revenue rose by 31% year-on-year, and the subscriber count for Office 365 consumer versions reached over 80.8 million, marking a 14% growth.

Notably, Microsoft's Office 365 for business versions are also thrivingThe company announced it had surpassed 400 million paid users, serving various enterprises such as BP, Elanco, ING, and Mediaset, indicating its vast presence in the business market.

The question arises: who boasts the deeper "moat"? Both Nvidia and Microsoft leverage vast markets as leading tech firms, but who truly has the edge in maintaining their competitive advantages?

From a business model perspective, Nvidia has carved out a niche by generating income based on technical superioritySince launching its CUDA programming platform in 2006, Nvidia has allowed GPUs to harness parallel processing capabilities to meet complex computational demands
