NVIDIA has officially detailed its new Blackwell B200 GPU and GB200 Superchip architectures, representing the largest generational leap in computational density in the company's history.
### Architecture & Performance The Blackwell GPU packages 208 billion transistors on a custom TSMC 4NP process, connecting two separate dies via a 10 TB/s high-bandwidth link into a single unified processor. For AI workloads, Blackwell introduces the second-generation Transformer Engine supporting FP4 precision, delivering up to 20 Petaflops of AI compute. This architecture yields 4x faster LLM training speeds and 30x faster real-time inference compared to the previous Hopper H100 generation.
### Form Factor, Cost & Availability NVIDIA is offering Blackwell in two primary form factors: individual B200 accelerator boards and the integrated GB200 NVL72 rack-scale system. The NVL72 connects 36 Grace CPUs and 72 Blackwell GPUs in a liquid-cooled cabinet acting as a single giant GPU. Individual B200 boards are priced between $30,000 and $40,000, while full GB200 NVL72 rack installations range from $3 million to $4 million. Production shipments have officially commenced, with massive datacenter deployments expanding through 2026.
### NVIDIA vs. AMD vs. Intel: Architecture Comparison NVIDIA's dominance relies on its proprietary Tensor Cores and CUDA software ecosystem, optimizing execution for neural network architectures. In contrast, AMD's Instinct MI300X offers an open-source ROCm platform and industry-leading memory density (192GB HBM3), making it a highly popular hardware alternative for training open weights. Meanwhile, Intel addresses general-purpose datacenter workflows, utilizing its Xeon CPU architectures coupled with Gaudi 3 accelerators that target cost-effective inferencing at a much lower price-to-performance ratio.
