Disclaimer: The performance metrics and comparisons discussed in this article are based on NVIDIA's specific benchmarks. While these figures highlight the potential of the Blackwell GPUs, actual performance may vary depending on individual workloads and configurations. Our goal is to provide clarity on these benchmarks to help you make informed decisions without any unintended misunderstandings.
Before you dive into the specifics, we encourage you to take a moment to check out our previous article on How to Rent H100 GPUs. It covers some foundational technologies that might be helpful if you're not yet familiar with them.
Recent industry reports reveal that NVIDIA has canceled plans for the B100 GPU due to packaging issues. Rather than pushing forward with a design that faced significant challenges, NVIDIA strategically refocused on the GB200, B200, and B200A GPUs for enterprise customers. These next-generation GPUs are expected to offer enhanced performance and efficiency, not only addressing the packaging concerns but also positioning NVIDIA to meet the rapidly growing demands of AI applications. This shift marks an important evolution in NVIDIA’s strategy, emphasizing scalable solutions that can support the most advanced AI workloads.
Blackwell is designed to outperform Hopper in every major aspect, including computational power, scalability, and energy efficiency. As Jensen Huang emphasized, "Hopper is fantastic, but we need bigger GPUs." This push for bigger, more efficient GPUs becomes critical when handling trillion-parameter models, which require immense computational resources. With Blackwell, NVIDIA delivers not only greater raw power but also the ability to operate efficiently, continuously, and with optimized energy consumption—thanks in part to the introduction of liquid cooling technology. Let’s dive into the specific advancements that set Blackwell apart.
One of the standout technologies introduced with Blackwell is the Grace Superchip, which significantly boosts FP64 and FP32 performance. These performance leaps aren’t just about raw computational power; they are critical for workloads that demand precision, such as climate simulations and quantum computing. By enhancing performance at this level, the Grace Superchip contributes to faster and more efficient AI model training and inference, making Blackwell an essential choice for organizations working on cutting-edge AI and scientific projects.
Blackwell’s liquid-cooled architecture is another key advancement, allowing the system to maintain efficiency even during the most demanding workloads. This is especially important for AI applications that require constant, high-power processing over extended periods. Combined with the 5th-gen NVLink interconnect technology, Blackwell offers 1.8TB/s bidirectional throughput per GPU, enabling seamless communication between up to 576 GPUs. These innovations work together to eliminate bottlenecks, ensuring that Blackwell can scale to meet the needs of the most data-intensive AI applications without sacrificing performance.
Blackwell takes a step forward by enhancing both AI training and inference compared to Hopper. The second-generation Transformer Engine boosts model training speeds by 30x and improves memory and power usage, making it ideal for large-scale data centers and scientific computing environments.
Blackwell’s advanced interconnect technologies, like NVLink-C2C, provide superior data throughput between multiple GPUs, overcoming some of Hopper's limitations in data-sharing efficiency. This makes Blackwell the ideal choice for industries involved in high-performance computing, AI model development, and real-time inference.
Additionally, Blackwell’s improved memory bandwidth enables faster computation and more efficient handling of large datasets. This architecture is essential for AI and scientific workloads managing the complexity of trillion-parameter models.
The following image by NVIDIA illustrates the performance gains enabled by the GB200 NVL72, which delivers 30x higher throughput for Mixture of Experts (MoE) models, significantly improving energy efficiency and lowering total cost of ownership (TCO) by 25x compared to previous-generation GPUs like the H100.
NVIDIA is set to introduce powerful GPUs under the Blackwell architecture: the HGX B200 and the GB200 series, featuring models like the GB200 NVL72 and GB200 NVL36. The NVL72 GB200 is particularly groundbreaking, consisting of two B200 GPUs connected via NVLink-C2C, forming a single, unified super-GPU that delivers unmatched computational performance. What sets it apart is that a single NVL72 node can house up to 72 Superchips, capable of achieving up to 1.44 exaFLOPS of FP4 performance. This scalability makes it ideal for extreme AI workloads and large-scale deployments, from training trillion-parameter models to real-time inference across a vast dataset.
The HGX B200, on the other hand, is designed for data centers, focusing on extreme parallel processing and massive memory bandwidth with HBM3 exceeding 3 TB/s. It’s tailored for industries needing peak performance in AI training and high-performance computing (HPC).

When it comes to AI model training, the NVL72 GB200’s dual-GPU configuration delivers unprecedented speed-ups. With 72 interconnected Superchips per node, even the most complex models, with trillions of parameters, can be trained efficiently—cutting months of development time into days. This level of performance is essential for organizations looking to scale their AI capabilities quickly and effectively. But it’s not just about speed—Blackwell’s architecture also ensures that large models can be trained without hitting performance bottlenecks, thanks to its superior memory bandwidth and interconnect technology.
The massive HBM3 memory bandwidth, exceeding 3TB/s, ensures seamless handling of enormous datasets and lengthy sequences, eliminating bottlenecks during large-scale computations. This ultimately accelerates time-to-market for AI innovations and ensures scalability, so no workload is too large for the the GB200 series.
However, it’s important to understand that the impressive training speedup results come from large-scale configurations that are common in AI-heavy organizations like OpenAI or Meta. For smaller configurations of 1 to 8 GPUs, users might expect closer to a 2.5x speedup, which still represents a substantial improvement. The additional performance boost in large setups comes from advancements in memory interconnect and data flow efficiency, thanks to NVLink and NVSwitch technologies, which significantly reduce the overhead typically seen in networked GPU clusters. Once your model is trained, you’ll need fast and efficient inference to deploy it in real-world applications.
While Blackwell excels in AI model training, its impact on inference is equally transformative. For real-time AI applications—whether in autonomous vehicles, real-time analytics, or any latency-sensitive environment—performance depends on low latency and high throughput. The NVL72 GB200 is specifically optimized for these use cases, ensuring rapid, efficient inference across massive datasets. With 900 GB/s NVLink bandwidth between its GPUs, data flows seamlessly, enabling smooth scaling across even the most complex models.
And again, NVIDIA’s claim of a 30x speedup for inference performance comes from a specific configuration optimized for very large-scale AI workloads, such as those running trillion-parameter models. In more typical setups, especially smaller inference models, users should expect improvements closer to 8x-10x, which still represents a transformative leap in performance. This difference in speedup largely comes from the transition to the FP4 precision format, which doubles the operations per second compared to FP8, as well as the superior shared-memory architecture that NVL72 employs.
As for the B200s, the recent NVIDIA’s MLPerf Inference v4.1 results show the B200 achieving up to 4x performance in tokens-per-second over the H100 for Llama 2 70B, demonstrating significant advancements in LLM inference.
