NVIDIA Investment Analysis: TPU Competition & Valuation Context

The Reddit discussion ([1] Reddit, 2025-11-28 EST) debates NVIDIA’s investment case amid competition from Google’s Tensor Processing Units (TPUs). Key pro arguments include:

• Ecosystem lead: Replacing NVIDIA with TPUs is not feasible due to CUDA’s dominance.
• Cost-effectiveness: Blackwell chips are 300% faster than TPUs, with lower total cost (58 Blackwells for $180M vs equivalent TPUs).
• Broader use cases: NVIDIA GPUs support training, inference, graphics, and scientific computing, unlike specialized TPUs.

Key con arguments:

• Valuation: PE ratio of ~50x (vs current 43.29x [0]) is high for a mature company.
• Margin risk: Competition from TPUs could reduce NVIDIA’s high margins (from 80% to 30%).
• Power efficiency: TPUs deliver 2x performance per watt compared to NVIDIA GPUs.

OP claims NVIDIA is undervalued at $180, targeting $210 by year-end and $260 next year.

• Short-term
  : NVIDIA’s stock is down 2.08% in after-hours trading ($176.51 [0]) and 12.20% over the past month [3]. This reflects valuation concerns (Gurufocus [5]) and competition news (Meta’s proposed Google Cloud TPU deal [6]).
• Medium-term
  : Analyst consensus remains bullish with a $250 target price (+41.6% from current [3]), supported by NVIDIA’s 80-90% AI GPU market share [6].
• Long-term
  : NVIDIA’s CUDA ecosystem moat [8] and data center revenue dominance (88.3% [3]) provide stability, but competition from TPUs/AMD could erode margins [6].

• Direct
  : NVIDIA (NVDA)
• Sectors
  : Semiconductors (Technology up 0.53% [4]), AI/data center
• Upstream
  : HBM suppliers (SK Hynix), semiconductor equipment (ASML)
• Downstream
  : Cloud providers (AWS/GCP/Azure), AI startups, enterprises

• Bull Case
  : Dominant market share [6], CUDA moat [8], high Blackwell ROI [7], analyst consensus [3]
• Bear Case
  : High valuation [3], margin compression risks [6], regulatory uncertainty [5]

• “Users should be aware that NVIDIA’s high valuation (PE ~43x [3]) may make it sensitive to growth slowdowns”
• “Competitive pressures from TPUs/AMD could impact NVIDIA’s margins over time [6][8]”
• “Regulatory outcomes from the Dec3 Senate meeting warrant careful monitoring [5]”
