Nebius and Navitas have both garnered attention as AI-related investments, amplified by their connections with Nvidia. While both have seen stock appreciation, their fundamental strengths differ, leading to varied valuation outlooks.
Navitas Semiconductor (NVTS) saw its stock price surge by 164% in May after being named a key partner for Nvidia's upcoming Kyber data center infrastructure. This new architecture supports Rubin-based server racks, expected to roll out in 2027. Nvidia's Kyber platform is redesigning data centers to use an 800V HVDC power architecture, moving away from the current 54V DC systems, to support the increasing power demands of AI server racks.
Navitas' GaN and SiC chip designs are crucial for this new architecture, with SiC chips used in the power room to convert AC to DC power and GaN-based power converters used at the server rack level.
The company is risky because financial terms were not disclosed in the announcements. The revenues from the venture aren't likely to come before 2027.
