NVIDIA H100 Tensor Core GPU vs NVIDIA GB200 Grace Blackwell
NVIDIA H100 Tensor Core GPU vs NVIDIA GB200 Grace Blackwell Superchip
These are two very powerful AI chips (GPUs) used in large AI models, supercomputers, and data centers.
1️⃣ H100 Chip (Hopper Architecture)
• Launch: 2022
• Architecture: Hopper
• Memory: 80 GB HBM3
• Memory Bandwidth: 3.35 TB/s
• Power Consumption: ~700 W
• Use: AI training, large language models, and supercomputing
👉 This chip is still widely used in many AI data centers around the world.
2️⃣ GB200 Chip (Grace Blackwell Superchip)
• Launch: 2024
• Architecture: Blackwell
• Combination: 1 Grace CPU 2 Blackwell GPUs
• AI Performance: Much higher (supports FP4 and FP6 precision)
• Memory: HBM3e high-bandwidth memory
• NVLink: 1.8 TB/s interconnect
• Use: Trillion-parameter AI models and massive AI clusters
👉 This chip is far more powerful than the H100.
A GB200 system can provide about 30× faster AI inference and around 4× faster AI training compared to H100-based systems.
🤖 Where These Chips Are Used
• AI models like ChatGPT
• Self-driving AI systems
• Robotics
• Space research simulations
• Large data centers
Major companies using or building systems with these chips include:
• NVIDIA
• OpenAI
• Google
• Microsoft
• Tesla
• Meta Platforms
These companies build massive AI supercomputers powered by thousands of GPUs.
🚀 How AI Is Trained Using These Chips
Powerful GPUs like the H100 and GB200 perform extremely fast calculations, which makes it possible to train very large AI models.
1️⃣ Data Collection
First, AI is given a huge amount of data, such as:
• Books 📚
• Websites 🌐
• Images and videos 🖼️
• Research papers
The AI learns patterns from this data.
2️⃣ Building a Neural Network
The “brain” of AI is an Artificial Neural Network.
It works in layers similar to neurons in the human brain.
Example structure:
Input Layer → Hidden Layers → Output Layer
3️⃣ Training on GPUs
During training, GPUs like H100 or GB200 perform millions or billions of calculations at the same time.
Main tasks include:
• Matrix multiplication
• Pattern detection
• Error calculation
This learning method is called Deep Learning.
4️⃣ Error Correction (Learning Process)
At first, the AI often gives incorrect answers.
An algorithm called Backpropagation is used to correct these mistakes.
Training cycle:
1. AI produces an answer
2. The system calculates the error
3. Model weights are updated
4. The AI becomes slightly more accurate
This process repeats millions or even billions of times.
5️⃣ Huge GPU Clusters
Training a modern AI model requires:
• Thousands of GPUs
• Multiple data centers
• Massive electricity ⚡
That is why large companies build AI supercomputers.
✅ Simple Example
If you want AI to recognize a cat, you show it millions of cat images.
Gradually, the AI learns the pattern of what a cat looks like and can identify cats in new images. 🐱
