Context Before

Evidence

For the Vera Rubin platform, Nvidia is asserting even more control over the system and rack level design. Rack scale integration and assembly have become more challenging, as every component is being pushed to the limit, whilst also optimizing for cost efficiency. VR NVL72 has a much more holistic design with a modular approach compared to Grace Blackwell for the purpose of integration efficiency and throughput.

Context After

Nvidia’s competitiveness strengthens with its extreme co-design supremacy. It is the only player with the best in class or close to the best in class silicon product offerings for all the major silicon contents in an Nvidia trail-blazed AI server system design. Nvidia offers the best accelerator, a SOTA scale up switch, the best NIC, and one of the best Ethernet networking switch, and a much improved purpose-designed CPU ↗. No other competitors have such a complete suite of integrated silicon products.

In the sections below, we will discuss the 6 silicon products of the Vera Rubin platform at the silicon level. Then, we will discuss the rack and compute tray evolution from Grace Blackwell to Vera Rubin from the design perspective and the implication to components: cables, connectors, PCB, thermal, mechanical, and power.
