NVIDIA B100 and NVIDIA B200 are both high-end enterprise AI GPUs. B100 is easier to deploy and still very powerful. B200 is built for data centers that want maximum performance at scale. Both require dedicated AI servers and cannot be used as simple GPU upgrades.


Architecture - NVIDIA Blackwell B100 vs B200


Both GPUs are built on the Blackwell architecture from NVIDIA.


What Blackwell brings:

  • Much higher AI throughput than Hopper

  • Native support for FP4, FP8, FP16, BF16

  • Better multi-GPU scaling with NVLink

  • Optimized for very large models


NVIDIA B100 and NVIDIA B200 share the same architecture. The difference is scale and power, not features.

What this means in practice:

  • NVIDIA B100 already outperforms NVIDIA H100/H200 by a large margin

  • NVIDIA B200 is tuned for maximum throughput, especially in large clusters


If your workload scales across many GPUs, NVIDIA B200 pulls ahead faster.

Real-world impact:

  • NVIDIA B100 fits more data centers without infrastructure changes

  • NVIDIA B200 often requires:

    • Liquid cooling

    • High-capacity PDUs

    • Modern AI-ready racks


If power or cooling is limited, NVIDIA B100 is usually the safer choice.



Form Factor & Compatibility - NVIDIA Blackwell B100 vs B200


This is where many people get confused.


Not PCIe GPUs

  • NVIDIA B100 and NVIDIA B200 are SXM GPUs

  • They do not go into standard PCIe GPU servers


Required platform

  • SXM GPU sockets

  • NVLink + NVSwitch

  • HGX or DGX-class systems


You cannot upgrade an existing GPU server to B100/B200. These GPUs require purpose-built AI servers.



How Many GPUs Fit in One Server - NVIDIA Blackwell B100 vs B200

Server type

GPU count

Typical enterprise AI node

8 GPUs

Rack-scale systems

64–72+ GPUs

Most deployments use:

  • 8× NVIDIA B100 or 8× NVIDIA B200 per server

  • All GPUs fully connected with NVLink


This allows the server to behave like one large accelerator, not eight separate GPUs.



Common Server Platforms Used - NVIDIA Blackwell B100 vs B200


NVIDIA B100 and NVIDIA B200 are mainly used in HGX-based and DGX-class AI servers, such as:


NVIDIA platforms

  • DGX B200 (8-GPU system)

  • Rack-scale NVLink systems (72-GPU class)


OEM enterprise AI servers

  • Supermicro HGX Blackwell servers

  • Lenovo ThinkSystem AI platforms

  • Dell PowerEdge AI (XE series)

  • ASUS and Gigabyte AI servers


Common traits of these systems:

  • 4U–10U chassis

  • Liquid cooling

  • Dual high-core CPUs

  • InfiniBand or high-speed Ethernet



Typical Use Cases - NVIDIA Blackwell B100 vs B200


NVIDIA B100 – Best fit when:

  • Power and cooling are limited

  • You want Blackwell performance without extreme density

  • You are building a balanced AI cluster

  • Cost efficiency per rack matters


NVIDIA B200 – Best fit when:

  • Maximum performance is the goal

  • You train very large models

  • You run inference at massive scale

  • Your data center is built for AI (power + cooling)
