Blackwell GPU

Introduction

Nvidia created Blackwell, a graphics processing unit (GPU) microarchitecture that succeeded the Hopper and Ada Lovelace microarchitecture.

The Blackwell architecture, named after statistician and mathematician David Blackwell, was leaked in 2022, with the B40 and B100 accelerators verified in October 2023, according to an official Nvidia roadmap displayed during an investor conference. On March 18, 2024, Nvidia made the official announcement at their GTC 2024 keynote.

Key Features of NVIDIA Blackwell

NVDIA Blackwell which is a GPU microarchitecture that succeeded the Hopper and Ada Lovelace microarchitecture has some features such as Dual-Die Design in which Blackwell GPUs use two reticle-limited dies coupled by a 10 TB/s NVLink-based connection to serve as a single GPU with 208 billion transistors , Advanced Memory Support where the architecture supports HBM3e memory for data center GPUs and GDDR7 for consumer GPUs, allowing for up to 30TB of rapid memory , It enhances AI Performance as Blackwell introduces fifth-generation Tensor Cores and new low-precision data formats like as MXFP4 and MXFP6, allowing for up to 1.4 exaflops of AI performance.

Product Lineup

Nvidia created Blackwell, a graphics processing unit (GPU) has some products being lined up such as Data Center GPUs where the B100 and B200 accelerators are optimized for AI and HPC workloads.  The HGX B200 server board links eight B200 GPUs, but the GB200 NVL72 system integrates 72 GPUs and 36 Grace CPUs in a single rack to provide exascale computing capabilities similarly it also has Workstation GPUs where the RTX Pro series includes devices such as the RTX Pro 6000, which has 96GB of GDDR7 memory, 24,064 CUDA cores, and a 600W power requirement.  This series is aimed at professionals in design, development, and data science industries ; another product which is being lined up is Consumer GPUs where the GeForce RTX 50 series, which includes products such as the RTX 5090 and RTX 5080, introduces Blackwell architecture to gaming and consumer applications, delivering significant performance gains over prior generations. ​

Availability

The RTX Pro series is planned to be available through distribution partners beginning in April, followed by greater availability from manufacturers like as Dell, HP, and Lenovo in May.  Consumer GPUs from the RTX 50 series are expected to arrive later this year. ​

Benefits and Limitations

When a coin is tossed there are always two sides heads and tails ; similarly, this technology also has some benefits and limitations.

Some of the benefits are massive AI performance as it Delivers up to 20 PFLOPS (FP4) per GPU, ideal for training and deploying large AI models , dual-die design as it increases scalability and reduces communication latency , energy efficiency as it uses new technologies to lower total power usage and it has advanced memory which Supports HBM3e for high-speed data processing.

Now let’s take a look at some limitations; Blackwell GPU is having high cost (premium pricing) which limits access to large organizations. There is a specific power demands which requires significant infrastructure for heat and power and its having a complex integration which needs updated systems and skilled teams for deployment.

Business Usefulness:

Blackwell GPU is going to be very useful for the business because it will help in accelerating AI innovation which would speed up model development and deployment cycles. It would help improve operational efficiency which would handle larger datasets faster with fewer systems. In case of businesses it would also help supporting advanced R&D which would be Ideal for biotech, finance, automotive, and other data-heavy sectors.

A Versatile Product Lineup for Every Segment

Availability Timeline

 NVIDIA has laid out a clear roadmap for the rollout of Blackwell-powered products:

1.    The RTX Pro series is set to be available through distribution partners beginning in April 2024.

2.    Major OEMs like Dell, HP, and Lenovo will begin offering Blackwell-powered systems by May 2024.

3.    GeForce RTX 50 series consumer GPUs are expected to launch later in 2024, likely targeting a Q3 or Q4 release window, aligning with the holiday season and major tech events.

Key Innovations and Features

• Dual-Die Design: A New Standard in GPU Engineering
• One of the most groundbreaking changes in Blackwell is its dual-die design. Traditional GPUs are typically built as a single silicon chip. However, Blackwell utilizes two reticle-limited dies—the largest size that can be manufactured using current lithography tools—connected using a 10 TB/s NVLink-based interconnect. This enables the two dies to operate seamlessly as one massive GPU, containing an astonishing 208 billion transistors.
• This design dramatically improves performance and scalability, allowing for more cores, memory bandwidth, and processing power—all in a single GPU package.
• Advanced Memory Support for Maximum Throughput
• Blackwell introduces support for cutting-edge memory technologies, tailored to both enterprise and consumer needs:
• HBM3e (High Bandwidth Memory): Used in data center GPUs, HBM3e delivers incredibly fast data transfer speeds and supports up to 30 terabytes of memory, making it ideal for complex AI training, simulation, and large-scale data analysis.
• GDDR7 Memory: Designed for consumer GPUs, GDDR7 provides faster speeds and lower latency, enabling smooth gaming, high-resolution rendering, and creative applications.
• This advancement ensures that Blackwell GPUs can handle data-intensive tasks with ease and speed.
• Enhanced AI Performance with Tensor Cores and New Formats
• Blackwell GPUs are equipped with fifth-generation Tensor Cores, specially optimized for AI workloads. These cores now support new low-precision data formats, including MXFP4 and MXFP6, which allow for highly efficient AI training and inference at reduced power costs without sacrificing accuracy.
• These enhancements enable Blackwell GPUs to deliver up to 1.4 exaflops of AI performance—bringing supercomputer-level processing to a single system. This leap is especially valuable for AI researchers, developers of large language models, and organizations building generative AI platforms.

Conclusion: A New Era Begins with Blackwell

NVIDIA Blackwell marks a bold leap forward in GPU architecture, bringing new levels of computing power, AI performance, and graphical capability to the world. Its unique dual-die design, advanced memory options, and cutting-edge AI cores make it one of the most versatile and powerful architectures ever created.

Whether you’re running large-scale simulations in a data center, designing the next big game, editing 8K video, or developing AI applications—Blackwell is designed to accelerate your journey.

The future of computing is here, and it’s powered by Blackwell.
