Tesla Ignites Massive 10,000-Unit NVIDIA H100 GPU Cluster to Turbocharge FSD Training

Tesla has recently made a groundbreaking move by activating a massive 10,000 unit NVIDIA H100 GPU cluster, aimed at accelerating the training of its Full Self-Driving (FSD) technology. This comes on the heels of the company bringing its in-house supercomputer, Dojo, into production last month. Both computational powerhouses are set to revolutionize Tesla’s approach to FSD and other AI-driven functionalities.

However, there seems to be some confusion regarding these two systems. While they are separate entities, they serve complementary roles in Tesla’s grand vision. Think of the NVIDIA H100 GPU cluster as akin to Apple using Intel chips—powerful but not fully optimized for Tesla’s specific needs. On the other hand, Dojo is like Apple’s in-house Silicon chips, hyper-optimized and custom-designed for Tesla’s unique requirements.

Together, they form a dual computational strategy that positions Tesla at the forefront of the automotive and tech industries.

Activation and Significance

Tesla’s activation of the NVIDIA H100 GPU cluster is a monumental step in the company’s journey toward achieving full autonomy in its vehicles. This cluster, comprising a staggering 10,000 units, is not just a technological marvel but also a strategic move. It serves as an external powerhouse that significantly boosts Tesla’s computational capabilities, especially in the realm of Full Self-Driving (FSD) technology.

NVIDIA H100 Performance

The NVIDIA H100 GPUs are a force to be reckoned with. Launched in late 2022, these GPUs are up to 30 times faster than their predecessor, the A100, and offer up to 9 times faster performance specifically for AI training. With 18,432 CUDA cores, 640 tensor cores, and 80 streaming multiprocessors, the H100 is engineered for high-performance computing at an unprecedented scale.


Design Focus on Graphics-Intensive Workloads

What sets the H100 apart is its design focus on graphics-intensive workloads, making it an ideal choice for video training, a crucial aspect of FSD technology. The H100’s architecture allows for easy scalability, enabling Tesla to train complex neural networks more efficiently. However, it’s worth noting that the H100 comes with higher energy usage compared to the A100, a trade-off for its superior performance.

NVIDIA H100 vs. A100

While the A100 GPUs served Tesla well for a period, the new H100 GPUs offer a level of performance and specialization that is more aligned with Tesla’s current and future computational needs. The transition to the H100 is not just an upgrade; it’s a strategic move that will significantly accelerate the development and deployment of Tesla’s Full Self-Driving technology.

Historical Context and Launch Date

The NVIDIA A100 GPU was a significant milestone when it was launched in late 2020. It was designed to cater to high-performance computing and artificial intelligence workloads, serving as the backbone for many computational tasks across various industries, including automotive AI. Tesla has been using the A100 GPUs for the last couple of years to train its FSD algorithms, among other tasks.

NVIDIA A100 Technical Specifications

The A100 came with 6,912 CUDA cores, 432 tensor cores, and an option for either 40 GB or 80 GB of high-bandwidth memory (HBM2). These specifications made it a formidable choice for high-performance computing tasks at the time of its launch. However, technology evolves rapidly, and the A100’s specs have been significantly outpaced by the new H100.

Performance Differences

The H100 GPUs offer a quantum leap in performance compared to the A100. They are up to 30 times faster and provide up to 9 times faster performance for AI training tasks. Specifically, high-performance computing is over 5 times faster on the H100 compared to the A100. This is largely due to the H100’s superior technical specifications, including 18,432 CUDA cores and 640 tensor cores.

Additionally, the H100 is designed for graphics-intensive workloads, making it particularly well-suited for video training, a critical component of FSD technology.

The Apple-Intel Analogy

To fully grasp the relationship between Tesla’s use of NVIDIA’s H100 GPUs and its own Dojo supercomputer, it’s helpful to draw an analogy with Apple’s transition from Intel chips to its in-house designed Silicon chips. For years, Apple relied on Intel’s processors for its range of Mac computers. These chips were powerful and got the job done, but they were not fully optimized for Apple’s specific needs and vision.

Similarly, Tesla’s use of NVIDIA’s H100 GPUs can be likened to Apple’s use of Intel chips. The H100 GPUs are incredibly powerful and offer a significant boost in performance, especially in the realm of Full Self-Driving technology. However, they are not custom-designed to Tesla’s exact specifications and requirements.

While they provide a robust solution for high-performance computing tasks, they may not be fully optimized for the unique challenges and opportunities that Tesla’s FSD technology presents.

How Tesla Plans to Use the NVIDIA H100 GPU Cluster for FSD

The NVIDIA H100 GPU cluster is specifically designed to handle graphics-intensive workloads, making it an ideal choice for video training, a crucial component of FSD technology. With its high-performance computing capabilities, the H100 allows Tesla to train complex neural networks more efficiently and effectively.

This is particularly important for FSD, which requires vast amounts of data to be processed and learned from. By leveraging the H100’s superior performance metrics, Tesla aims to overcome computational bottlenecks and speed up the iterative process of machine learning, thereby bringing FSD technology closer to full maturity.
