自作PCでの選び方・注意点

Meta MTIA v3 は「Meta Internal Recommendation system inference workload (Facebook Feed / Instagram Ranking / Threads / WhatsApp Algorithm)」「Llama 4/5 training infrastructure」「Meta AI Sovereignty (NVIDIA H100 dependence回避 strategy core hardware)」用途のHyperscaler AI Chip Meta-internal specific。Consumer / 自作PC範囲外・Meta Internal use only (Microsoft Maia 200 + AWS Trainium 3 + Google Trillium TPU v6 等の Customer access available Hyperscaler chip と differentiate・Meta Internal use exclusively で Cloud customer access無)・Meta Multi-vendor AI strategy alignment (NVIDIA H100 350,000 chip + AMD MI300X 50,000 chip + Meta MTIA v2/v3 Internal の Multi-vendor approach・$65B+ accumulated 2024年AI infrastructure investment Total) で Meta Sovereignty preference + Cost optimization + Performance optimization triple alignment。Meta Recommendation system specific optimization (Facebook Feed Algorithm 32M+ DAU + Instagram Ranking + Threads social graph processing + WhatsApp / Messenger AI workload) で General-purpose AI chip (NVIDIA H100 / Google TPU v6) vs Meta workload specific optimization advantage。
