NVIDIA GTC 2025 Part 3: Exhibit Hall - Hardware and Robotics
This is Part 3 of a 3-part series covering GTC 2025:
- Part 1: Keynote and Main Announcements
- Part 2: Deep Dive into CUDA
- Part 3: Exhibit Hall - Hardware and Robotics (this post)
Exhibit Hall

In this final post, i explore the exhibit hall where many innovations from NVIDIA and its partners were on display. The exhibit hall was a lot of fun! Here are some of the most interesting exhibitors and equipment I managed to take a picture of.
Server Racks and Infrastructure
Liquid-cooled racks consuming 150KW+ were on display — air cooling is no longer viable at these power levels.
GB300 Hardware
The NVIDIA GB300 Grace Blackwell Ultra Superchip features four NVIDIA Blackwell Ultra GPUs, two NVIDIA Grace CPUs, and four NVIDIA ConnectX-8 SuperNICs. The compute trays and NVLink switch trays are the building blocks of the GB300 NVL72 rack-scale solution.
Cooling Solutions

Water has 1000X more cooling capacity than air, is 25X better at transferring heat, and requires 10X less energy to move heat — making liquid cooling essential for modern AI infrastructure.
Robotics
Humanoid robots, exoskeleton demonstrations, and autonomous robots were on display throughout the exhibit hall, showcasing the physical AI capabilities powered by NVIDIA’s Isaac platform.
Conclusion
Overall the conference was a lot of fun, with many interesting sessions and opportunities to meet experts and practitioners in the field. The sessions were well presented with energetic and clearly-expert presenters who were passionate about their topics.
Finally, doris.ai had a digital screen next to the conference store to help people digitally try clothes on, and I couldn’t resist trying Jensen’s signature black leather jacket:

This concludes the 3-part series on GTC 2025. Check out Part 1 and Part 2 if you missed them.
