Specialized chips (ASICs) like Google's TPU lack the flexibility needed in the early stages of AI development. AMD's CEO asserts that general-purpose GPUs will remain the majority of the market because developers need the freedom to experiment with new models and algorithms, a capability that cannot be hard-coded into purpose-built silicon.

While purpose-built chips (ASICs) like Google's TPU are efficient, the AI industry is still in an early, experimental phase. GPUs offer the programmability and flexibility needed to develop new algorithms, as ASICs risk being hard-coded for models that quickly become obsolete.
Top-tier kernels like FlashAttention are co-designed with specific hardware (e.g., H100). This tight coupling makes waiting for future GPUs an impractical strategy. The competitive edge comes from maximizing the performance of available hardware now, even if it means rewriting kernels for each new generation.
The massive demand for GPUs from the crypto market provided a critical revenue stream for companies like NVIDIA during a slow period. This accelerated the development of the powerful parallel processing hardware that now underpins modern AI models.
Major AI labs aren't just evaluating Google's TPUs for technical merit; they are using the mere threat of adopting a viable alternative to extract significant concessions from Nvidia. This strategic leverage forces Nvidia to offer better pricing, priority access, or other favorable terms to maintain its market dominance.
The debate on whether AI can reach $1T in revenue is misguided; it's already reality. Core services from hyperscalers like TikTok, Meta, and Google have recently shifted from CPUs to AI on GPUs. Their entire revenue base is now AI-driven, meaning future growth is purely incremental.
AI's computational needs are not just from initial training. They compound exponentially due to post-training (reinforcement learning) and inference (multi-step reasoning), creating a much larger demand profile than previously understood and driving a billion-X increase in compute.
Arvind Krishna forecasts a 1000x drop in AI compute costs over five years. This won't just come from better chips (a 10x gain). It will be compounded by new processor architectures (another 10x) and major software optimizations like model compression and quantization (a final 10x).
The competitive threat from custom ASICs is being neutralized as NVIDIA evolves from a GPU company to an "AI factory" provider. It is now building its own specialized chips (e.g., CPX) for niche workloads, turning the ASIC concept into a feature of its own disaggregated platform rather than an external threat.
The narrative of endless demand for NVIDIA's high-end GPUs is flawed. It will be cracked by two forces: the shift of AI inference to on-device flash memory, reducing cloud reliance, and Google's ability to give away its increasingly powerful Gemini AI for free, undercutting the revenue models that fuel GPU demand.
While competitors like OpenAI must buy GPUs from NVIDIA, Google trains its frontier AI models (like Gemini) on its own custom Tensor Processing Units (TPUs). This vertical integration gives Google a significant, often overlooked, strategic advantage in cost, efficiency, and long-term innovation in the AI race.
