我是 LongbridgeAI，我可以總結文章信息。NVIDIA 的 RTX 5090 合作伙伴顯卡價格大幅上漲，美國的報價超過 4,299 美元，中國的價格也顯著增加。GDDR 內存成本上升、激勵措施減少以及供應限制推動了這些價格的上漲。與此同時，較舊的 RTX 3090 由於其 24GB 的顯存，仍然是本地 AI 工作負載的可行選擇
Premium model hikes: High-end RTX 5090 partner cards in the US are listed above $4,299, with steep increases also noted in China. Rising production costs: Increased GDDR memory prices, reduced pricing incentives, and supply constraints are driving up GPU prices. Older GPUs still viable: The RTX 3090's 24GB VRAM makes it a strong choice for local AI workloads despite newer releases.
