Key Highlights
- Nvidia Blackwell GPUs: The new racks feature liquid-cooled GPUs, including one Grace CPU and one B200 AI GPU, achieving an impressive 90 TFLOPS of FP64 compute power.
- Customized Racks: The exact configuration of Google’s GB200 racks remains undisclosed, but they are tailored for optimal performance in AI workloads.
- Sustainable Infrastructure: Google emphasizes its commitment to building a sustainable compute infrastructure in collaboration with Nvidia.
- Power Requirements: An NVL72 GB200 machine, equipped with 72 B200 graphics processors, is estimated to require around 120 kW of power.
- Overcoming Design Flaws: Nvidia faced delays with the Blackwell GPU family due to design flaws, which have since been resolved.
Google’s GB200 Rack Design
Google’s presentation of the GB200 NVL racks showcases the company’s dedication to innovation in AI infrastructure. The images reveal a sophisticated setup featuring liquid-cooled GPUs.
Each rack comprises one Grace CPU paired with one B200 AI GPU, collectively delivering up to 90 TFLOPS of FP64 compute performance.
In a post on X (formerly Twitter), Google Cloud remarked, “We’ve been working closely with Nvidia to sustainably build the compute infrastructure of the future.”
This partnership highlights Google’s focus on not only performance but also sustainability in its technology initiatives.
The provided images depict two racks side-by-side, integrating Nvidia’s Blackwell cards into Google’s broader infrastructure, which includes power distribution units, networking switches, and cooling distribution units.
While Nvidia recommends using InfiniBand for connectivity, sources suggest that Google may employ Ethernet switches, given its unique infrastructure requirements.

Microsoft’s Preview and Comparisons
Just a week prior to Google’s announcement, Microsoft revealed that it has already deployed Nvidia Blackwell systems in its cloud infrastructure. However, there are notable differences between the two companies’ implementations.
Microsoft’s approach differs in that it optimizes the design to allocate additional rack space for distributing coolant to local heat exchangers.
This distinction emphasizes the varied strategies that leading tech companies are employing as they enhance their AI capabilities.
Both Google and Microsoft aim to position themselves as leaders in the burgeoning AI cloud services market, leveraging cutting-edge technologies to meet increasing demand.
Nvidia’s Blackwell GPU Family
Nvidia first announced the Blackwell GPU family in March 2024. Nvidia built these GPUs using a custom-designed two-reticle limit 4NP process by TSMC. The architecture interconnects the GPU dies through a rapid 10TBps chip-to-chip link, creating a cohesive and powerful GPU system.
One of the most impressive aspects of the Blackwell architecture is its staggering transistor count. With 208 billion transistors, this marks a significant leap from the 80 billion found in the previous Hopper series.
Additionally, Blackwell introduces a second-generation transformer engine alongside new four-bit floating point AI inference capabilities, making it a powerhouse for AI workloads.
According to estimates, a machine configuration featuring 72 B200 graphics processors would demand around 120 kW of power.
This requirement reflects the intense computational needs associated with advanced AI tasks, underscoring the importance of efficient power management in data center operations.
Overcoming Challenges
Earlier reports in August indicated that the Blackwell GPU family was experiencing delays due to an unforeseen design flaw.
However, Nvidia announced later that month that the issue had been resolved. This resolution was crucial for maintaining Nvidia’s timeline for the launch of the Blackwell architecture, which is poised to be a significant player in the AI GPU market.
With both Google and Microsoft racing to deploy Nvidia’s latest technology, the competition in AI infrastructure continues to heat up.
These developments not only represent advancements in computing power but also signal a shift towards more sophisticated and efficient AI capabilities in the cloud.
Conclusion
The unveiling of Google’s Nvidia Blackwell GB200 NVL racks signals a new era in AI cloud infrastructure.
As companies like Google and Microsoft vie for leadership in the AI landscape, the introduction of these advanced GPUs promises to reshape the capabilities and efficiencies of cloud computing.
As the demand for AI services continues to grow, the competition will drive further innovation in the industry.
With Nvidia’s Blackwell architecture leading the charge, we can expect significant advancements in the performance and efficiency of AI applications across various sectors.
