TSMC is a key bottleneck limiting Nvidia's AI growth, per analyst Michael Parekh. AMD is ramping 2nm Venice CPUs on TSMC's node and investing over $10B in Taiwan's AI supply chain, boosting AMD's stock. TSMC's growth may slow, challenging income ETFs like IDVO. Investors are broadening AI chip bets beyond TSMC as competition from MediaTek and Samsung rises.
