NVIDIA RTX Blackwell: A Giant Graphics Card for Tasks of the Future

Recent leaks have revealed information about NVIDIA's new RTX Blackwell series professional graphics card, which features 96GB of GDDR7 memory and a 512-bit bus. This is a significant increase in memory capacity compared to previous professional models that offered up to 48 GB.

Impressive Memory Capacity and Speed

The main highlight of the news is, of course, 96 GB of GDDR7 memory. For comparison, current-generation flagship cards like the RTX 4090 feature 24GB of GDDR6X; quadrupling the memory capacity is a huge leap!

GDDR7 is expected to deliver significantly higher throughput than GDDR6X, which is critical for handling high-resolution textures, complex game scenes, and AI and rendering workloads.

512-bit Bus: the Road to Maximum Bandwidth

GDDR7 is used together with a 512-bit memory bus. The memory bus determines the “width” of the data channel between the GPU and memory. A wider bus allows more data to be transferred per cycle, which directly affects memory bandwidth.

The 512-bit bus, combined with GDDR7, should provide the staggering bandwidth needed to unlock the potential of the Blackwell architecture and handle the most demanding tasks.

Other Features

The workstation card is likely to use the PG153 board, which has never been used in any graphics card before. It is also likely to feature the GB202 GPU, Blackwell's only desktop chip with a 512-bit bus.
