### Don't Just Stare at GPUs! Four Hidden Lines in AI Hardware for H2, Choose Wrong Direction and Waste Half a Year Time: 2026-07-31 22:13:14 Content: First, look at a set of data to feel how crazy the first half was: Shenwan Electronics +86%, while the CSI 300 was only +8%; Philadelphia Semiconductor +101%, while the Nasdaq was only +13%. Tech hardware was the unanimous MVP in the first half, no controversy. But after rising to this level, how to play in the second half? Many people's mentality has changed from 'charging in with eyes closed' to 'fear of being stranded'. Direct conclusion: the rally is not over, but the second half is a verification period, looking at whether orders can turn into profits. If you choose the wrong direction, you may lose money even if the index rises. Four hidden lines, break them down one by one. Hidden line 1: CPU goes from supporting role to bottleneck. GPU is responsible for computing, CPU for management. In the agent era, a task requires repeated model calls, information retrieval, and state storage, causing CPU workload to skyrocket. Intel gave a key data point: the CPU-to-GPU ratio in AI systems is moving from 1:8 to 1:4, and may reach 1:1 in the future. If you pile up too many GPUs and CPU scheduling and data supply cannot keep up, GPUs will not run at full capacity.
