華為晶片不夠香!被自家人嫌棄 中國大廠砸巨資求助輝達

字節跳動、阿里巴巴與騰訊訂購大量輝達RTX PRO 5500晶片,儘管面臨供應鏈延遲與出口限制

Quick Look

儘管華為正縮小NPU市場差距,但字節跳動、阿里巴巴與騰訊等中國科技巨頭仍優先選擇輝達晶片。受限於美國出口禁令,這些公司已訂購逾300萬塊輝達RTX PRO 5500,總訂單金額高達350億美元,顯示輝達在CUDA生態與性能上的絕對優勢。

AI-generated summary

Why It Matters

美國政府對輝達高階晶片出口中國實施嚴格限制,迫使中國科技公司尋求替代方案或透過非正規管道獲取資源。

儘管華為在中國人工智慧加速器(NPU)出貨量方面正逐漸縮小與輝達的市場差距,但字節跳動、阿里巴巴和騰訊等中國頂級科技公司顯然已經表明,頂級圖形晶片製造商輝達將是他們的首選,這得益於GPU的原始性能和對CUDA的支持。

一份最新報告指出,由於美國對輝達B300顯示卡的禁令,這些公司已訂購超過300萬塊輝達RTX PRO 5500 顯示卡用於訓練其人工智慧模型。然而,即使是輝達也無法保證所有訂單都能準時交貨。

儘管發貨可能存在延遲,但中國企業幾乎已經接受了目前沒有比這些GPU更好的替代方案。

根據路透報導,位元組跳動、阿里巴巴和騰訊的總訂單金額估計高達350億美元,遠超過華為的產能。

鑑於輝達的B300晶片尚未獲得美國授權出口中國,而華為的H200晶片也受到許可限制,為了避免不必要的出口麻煩,華為顯然應該選擇其Ascend系列晶片。然而,輝達在CUDA支援和原始性能方面的優勢,也解釋了為什麼華為不得不採用多晶片堆疊的方式來彌補這些不足。

輝達RTX PRO 5500對於這些中國公司來說是一個不錯的選擇,因為單一GPU就配備了高達84GB 的DDR7 ECC顯存、21760個CUDA核心以及1.398TB/s的顯存頻寬。

從紙面數據來看,華為Ascend 950PR憑藉其128GB HiBL 1.0顯存和1.4-1.6TB/s的顯存頻寬,以及與RTX PRO 5500大致相同的功耗,無疑是更優的選擇。然而,軟體支援與硬體同樣重要。據報導,輝達告知合作夥伴,他們可能只能拿到5-10%的份額,而來自中國客戶的總訂單量已超過600萬塊。

What to Watch

AI outlook — possibilities, not facts

  • 中國科技公司將持續尋求輝達晶片替代方案以規避出口禁令。
