Tokens per Watt Decides Your 2026 GPU and Cooling
The primary constraint for AI compute in 2026 will shift from raw processing power to efficiency, specifically tokens per watt. This is because inference, which now accounts for the majority of AI compute spend, is fundamentally a power-bound problem, especially in data centers with fixed power allocations. Consequently, the most efficient GPUs that maximize tokens generated per megawatt will be prioritized over those with the highest FLOPS. Advancements in serving software and numerical precision, such as FP8 and FP4, can significantly reduce the cost per token without requiring new hardware, offering a more immediate and cost-effective solution than simply acquiring more GPUs.
