The Dawn of a New Era: Google’s A4X VMs Powered by Nvidia GB200
Google has unveiled its latest innovation, the A4X virtual machines (VMs), powered by Nvidia’s groundbreaking GB200 NVL72 architecture. These VMs are designed to handle the heaviest of workloads, especially for large-scale AI tasks.
Unmatched Performance for Complex AI Models
Google’s A4X VMs, featuring more than an exaflop of training performance, offer a fourfold leap in training performance compared to the A3 VMs. This is especially significant for reasoning models and large language models (LLMs) with extensive context windows, addressing issues previously tackled with lesser computational power.
Exclusive Deployment: A Google First
As the first cloud provider to leverage both B200s and GB200s, Google positions itself at the forefront of AI-enabled cloud solutions, according to a blog post by industry experts George Elissaios and Roy Kim.
Advanced Networking with Titanium ML
The A4X VMs come equipped with Tesla’s Titanium ML network adaptor based on Nvidia ConnectX-7 NICs. This delivers up to 28.8TBps of non-blocking GPU-to-GPU traffic, enhancing connectivity and efficiency in AI computations. All this is integrated into Google’s Jupiter network fabric, ensuring seamless interconnectivity.
Real-Life Applications and Future Possibilities
Since the redevelopment of Nvidia Blackwell GPUs, companies like Lambda Labs have rapidly deployed these new capabilities. Lambda Labs deployed GB200 NVL72 racks at EdgeCloudLink’s data center, which is powered by hydrogen, indicating a shift towards sustainable data center innovations. CoreWeave has also introduced GB200 NVL72 instances to its cloud platform, emphasizing the growing demand for high-performance computing solutions.
Early Adoption and Competitive Dynamics
In January 2025, Lambda Labs was a pioneer in deploying GB200 NVL72 racks, highlighting a broader trend towards accelerating AI capabilities. Microsoft was earlier in harnessing the power of Blackwell with GB200 GPUs, indicating a competitive advancement wave among tech giants.
