雖然距離上市和效能解禁尚有一些時日，但 NVIDIA GeForce RTX 4090 顯卡的外觀已正式解禁，來近距離欣賞新一代 Founders Edition 創始版的外觀與設計吧！
這次外包裝捨棄了傳統的套盒結構，改用兩塊等腰直角三角柱組合成一塊正方形的四角柱，只需用手撕去側邊的封條即可展開，再也不用像過去得慢慢把套盒甩出來。外觀的其中一面只印上簡單的型號字樣，另一面則有創始版經典的 8 字形框體的意象。
這一代顯卡最大的改動就是全面導入符合 ATX 3.0 (PCIe 5.0) 規範的 12VHPWR 電源接頭，採用 12 + 4 pin 設計，單一組接頭／線材最高可輸送高達 600W 的超大電量。
GeForce RTX 4090 創始版內附的是由 4 組 PCIe 8 pin 融合成的轉接線，但 NVIDIA 表示其實只需 3 組 PCIe 8 pin 電源即可正常驅動，需要超頻再接上第 4 組即可。
這次創始版的外觀結構其實是沿用上一代設計，包括 V 形 PCB、提供氣流穿越的雙面風扇、8 字形金屬框體等特色。散熱機也維持以均熱板為主體，搭配熱導管將熱量傳導至鰭片上。框體倒是加上了類似腰身的內凹設計，看起來更活潑一些。
細節方面還是有小小改動，這回均熱板可直接透過導熱介質接觸 GDDR6X 記憶體顆粒，而且搭配 Micron 美光全新的製程，單一顆粒容量為 2GB，這樣所有記憶體顆粒都集中在 PCB 正面，可直接透過散熱器導出熱量，有效解決過往被詬病的 GDDR6X 記憶體高熱問題。
PCB 這次更直接動用了 23 相供電，不只可讓電流變動反應時間縮短 10%，穩定性也控制得更好以，還能分攤龐大電流過度集中在較少供電相數帶來的高溫。
當然，因為 GeForce RTX 4090 創始版的全卡功耗已來到 450W，比 RTX 3090 創始版還多出 100W，因此雖然散熱器尺寸看起來沒什麼變化，但實際厚度上從前一代的大約 2.7 槽到這一代變成完整的 3 槽，隨附的風扇也加大，以便增加風通量。
總之，NVIDIA GeForce RTX 4090 Founders Edition 創始版詳細的效能與評測將在台灣時間 10 月 11 日 21:00 解禁，敬請期待。
