先来看一下 Gemini 关于 NVLINK vs UALINK:
NVLink and UALink are both high-speed communication fabrics designed to connect multiple AI accelerators (like GPUs) together, but they differ fundamentally in their ecosystem and scale. NVLink is NVIDIAs proprietary, closed ecosystem with unmatched per-chip speed, whereas UALink is an open standard created by an industry consortium to allow hardware from different vendors to communicate
AI Computing 两个不同的世界,一个是NVidia 使用NVLink,另一个是 non-NVidia 使用UALink(GOOG/AVGO, AMZN, MSFT, META, etc).
Marvell (MRVL) 在两个城市之间架了一座桥--- 用 NVLink Fusion。目前似乎只有MRVL有这个桥。所以是很独特。
但是MRVL这座桥的市场有多大?感觉还是城市的市场/市值比桥的市场/市值大。所以AVGO可能空间更大?
MRVL和AVGO都各有特色。都有前途。
