NVIDIA's GB300 AI servers are set to be unveiled at this year's GTC 2025 conference and will mark the transition towards fully "liquid-cooled" AI clusters.
NVIDIA's Blackwell Ultra GB300 AI Servers Set To Feature Significantly Larger TDPs Than The GB200, With Top-Notch Cooling Performance
Team Green will unveil the next revolution in the AI industry at GTC 2025. This time, the firm is expected to feature its highly-anticipated "Blackwell Ultra" lineup, which is a much more refined version of the existing Blackwell architecture. While details about NVIDIA's upcoming AI products, notably the GB300 lineup, are slim, we now know that the firm is set to "beef up" the cooling mechanism on the AI servers by up to four times compared to the existing GB200 clusters since the performance with Blackwell Ultra will be too "hot to handle."
In a report by Taiwan Economic Daily, it is claimed that the GB300 AI servers are "fully liquid-cooled," removing elements of air-cooled systems. In anticipation of this, the Taiwanese supply chain has seen massive demand for liquid-cooling essentials, given that NVIDIA plans to ramp up the production of Blackwell Ultra soon, since the demand is said to be higher than what we saw with the original Blackwell. It is claimed that heat dissipation figures for the GB300 are much higher than those of its predecessor; hence, optimal cooling is necessary.
Using liquid cooling is expected to massively raise the GB300 AI servers' price. Given that the current GB200 NVL72 servers cost around $3 million, it is imminent that the pricing of the GB300's top configuration will be much higher, and that will ultimately translate into more revenue for NVIDIA. However, given the yield rate issues surrounding Blackwell, it would be interesting to see whether customers would opt for the GB300 in huge numbers. Still, given NVIDIA's dominant presence in the market, it certainly looks imminent.
For a quick rundown on the Blackwell Ultra "B300" series, it is rumored that NVIDIA is planning to go big on power figures this time, as the GB300 AI server is supposed to feature up to 1400W of TDP, which is a massive rise. With the architectural upgrades, we are looking at around 1.4 times higher FP4 performance when compared to the previous generation and higher memory capacity from 192 GB to 288 GB by effectively utilizing 12-Hi stacks of HBM3E technology.
This year's GTC won't only showcase a single lineup, rather NVIDIA has plans to unveil its Vera Rubin lineup as well, giving a rundown on its status, although supply chain launch isn't expected for now.
