About NVIDIA Hopper 

NVIDIA Hopper was launched in 2022 and named after Grace Hopper, a pioneering computer scientist and U.S. Navy rear admiral who was instrumental in the development of computer programming languages. The NVIDIA Hopper architecture excels in tasks like transformer-based AI models, large-scale language models (LLMs), and scientific computing. With 80 billion transistors and HBM3 memory, the H100 GPU offers up to 4 petaflops of AI performance, making it ideal for enterprises and research institutions working on AI, large-scale data centres, and scientific simulations. Hopper’s Transformer Engine is key for accelerating tensor operations, essential for deep learning tasks. 

Beyond performance, Hopper also introduced Confidential Computing capabilities, which offer enhanced data security, allowing enterprises to protect sensitive information while performing complex computations.  

About NVIDIA Blackwell 

NVIDIA Blackwell was released in 2024 and named after David Harold Blackwell, a renowned statistician and mathematician whose work in probability theory and dynamic programming has had a lasting impact on computational sciences. Blackwell’s contributions to the field of mathematical statistics align with the architecture’s focus on generative AI, LLMs, and data-centric workloads. 

The NVIDIA GB200 GPU from the Blackwell series boasts 208 billion transistors and HBM3e memory, offering a massive leap in performance compared to the Hopper series. With up to 20 petaflops of AI performance, Blackwell is designed to handle the most demanding computational tasks, such as training large AI models, running complex simulations, and accelerating generative AI applications. 

One of Blackwell's standout features is its dedicated decompression engine, which speeds up data processing by up to 800 GB/s—making it 6x faster than Hopper when dealing with large datasets. Blackwell also enhances Confidential Computing, ensuring a secure and efficient environment for sensitive AI workloads, while introducing breakthroughs in quantum simulations and scientific research, making it the next frontier in AI and HPC computing.
