Nvidia、AMD、Google、Amazonが設計した各AIチップについて、メモリ(HBM)、ロジックチップ、先進的パッケージング(CoWoS)、補助部品の4つのコンポーネントカテゴリーの1チップあたりのコストを推定します。その後、各1チップあたりのコストを予測される四半期生産量に掛けて、各カテゴリーの総コンポーネント支出を算出し、2024年第1四半期から2025年第4四半期までの各四半期における各カテゴリーの総コンポーネント支出の割合を計算します。

私たちは、この期間中にメモリの割合が52%から63%に上昇し、パッケージングが19%から15%に、補助部品が15%から9%に減少したことに気づきました。ロジックチップの割合は約13~14%でほぼ一定のままでした。AIチップの総部品支出は2024年の約220億ドルから2025年の520億ドルに成長し、そのうちの約200億ドルはHBM支出にあたります。
