Nvidia’s market stronghold

The era of artificial intelligence (AI) supremacy is defined by raw compute power, software ecosystems and manufacturing scale. Nvidia currently claims about 80% of the AI training market and up to 95% of inference workloads.

Yet IntelAdvanced Micro Devices (AMD), hyperscale cloud providers, and innovative startups are chipping away at Nvidia’s dominance..

A crowded battlefield: rivals apply pressure

Nvidia's dominance faces challenges from four primary fronts:

  1. Established chipmakers sharpen their AI focus
  2. Cloud giants embrace custom AI silicon
  3. Startups disrupt with novel architectures
  4. Edge computing transforms AI deployment

Market trends Apple, Qualcomm, OpenAI Triton Edge AI processing, software alternatives to CUDA

Rubin: a quantum leap in performance

Nvidia's response to these challenges is the Rubin architecture, named after astronomer Vera Rubin. This groundbreaking platform combines a next-generation graphics processing unit (GPU) built on  Taiwan Semiconductor Manufacturing Company (TSMC)'s 3 nanometre (nm) process with Nvidia's first custom central processing unit (CPU), Vera, creating an integrated 'superchip.'

Performance-per-watt comparison chart

Chip model Peak performance (petaflops) Power draw (watts) Petaflops per watt
Nvidia H100 4 (FP8 with sparsity) 700 0.0057
Nvidia Blackwell 20 (FP4) 900 0.0222
Intel Gaudi 3 1.8 (BF16/FP8) 600 0.0030
AMD MI350 2.6 (estimated, FP8) 600 0.0043

Nvidia Blackwell leads in energy efficiency, delivering roughly four times the petaflops per watt of the H100.

Supply-chain & geopolitical context

TSMC’s 3 nm capacity is nearly booked through 2026. Nvidia holds a large share of those wafers for Blackwell and Rubin, with AMD, Intel and Apple also securing booked volumes. Rising wafer costs (up 3 to 6% for 3 nm) and Taiwan-centric risks add execution challenges.

Nvidia’s volume reservations grant scale advantage but expose it to geopolitical tensions in semiconductor supply.

Words from the top

“Custom silicon and open software ecosystems are the foundation of AI’s future. By tightly integrating hardware and software we unlock unprecedented performance and efficiency that power the world’s most ambitious AI workloads.”

- Jensen Huang, Nvidia CEO

“Energy efficiency is not just about the chip; it’s about the entire system -  architecture, packaging, software and data centre infrastructure working in harmony.”

- Mark Papermaster, AMD CTO

Nvidia's reign continues

In a fiercely competitive landscape, Nvidia's unrelenting innovation in H100, Blackwell, and Rubin architectures, combined with its robust ecosystem, solidifies its position as the leader in AI chips. While rivals like Intel and AMD continue to make strides, and emerging threats from startups and open-source initiatives keep Nvidia on its toes, the company's supercharged roadmap and ecosystem advantages set a high bar for competitors to overcome.

As the AI revolution unfolds, Nvidia appears well-positioned to maintain its reign in the AI chip market for the foreseeable future.
