Context Before

We believe that this variant of NVL72/NVL36x2 will have lower upfront capital cost compared to the Grace CPU version, with less revenue flowing to Nvidia. Since it is using an x86 CPU, there will be much lower CPU to GPU bandwidth compared to Grace C2C which can talk to the GPUs at up to 900GB/s bidirectional (450GB/s). Because of this TCO is questionable. Furthermore as the x86 CPUs will not be able to share power between the CPU and GPUs to optimize for the workload total peak power required is much higher. In our accelerator model, we have broken down which GB200 form factors & the exact volume each of the top 50 buyers will be deploying. ↗
