Nvidia GB300 Blackwell Ultra for AI at GTC, Will Be Fully Liquid-Cooled
NVIDIA will launch the GB300 'Blackwell Ultra' AI servers at GTC 2025, featuring fully liquid-cooled systems to manage a TDP of 1400W. This new architecture boasts improved memory capacity and 1.4x floating point performance over previous models, though the premium design may affect pricing and customer purchasing behavior.
Key points
- GB300 servers feature integral liquid cooling, eliminating air-cooled components.
- The TDP of 1400W necessitates advanced cooling solutions, marking a significant increase from previous servers.
- Memory capacity jumps from 192 GB to 288 GB due to HBM3E technology with 12-Hi stacks.
- Increased server costs may impact customers' purchasing decisions and NVIDIA's revenue.
- High demand for liquid cooling components is reflected in the Taiwanese supply chain.
- Existing GB200 NVL72 servers cost around $3 million; GB300's top configurations may exceed this price.
Why it matters
- The move to liquid cooling aligns with the broader trend in the tech industry for sustainable designs and performance optimization.
- As of 2025, major tech companies are increasingly adopting liquid cooling solutions to handle higher power densities in computing.
- NVIDIA's development reflects a competitive landscape in AI computing, driven by the need for enhanced performance, efficiency, and thermal management.
The introduction of the GB300 'Blackwell Ultra' at GTC 2025 positions NVIDIA at the forefront of AI server technology, exemplifying a significant shift toward advanced cooling solutions while responding to market demands for higher performance and efficiency.
