Gigabyte XLS4-SX2-LAS1 New 8x NVIDIA RTX Pro 6000 Blackwell Liquid-Cooled
In the booth, we saw a really neat server. This is the Gigabyte XLS4-SX2-LAS1 designed for the new, liquid-cooled NVIDIA RTX Pro 6000 Blackwell edition GPUs.
On the front, there are eight E1.S SSDs.
On the bottom, you will see eight of the NVIDIA RTX Pro 6000 Blackwell GPUs. The network ports below them are from the NVIDIA ConnectX-8 PCIe switch board so those are 8x 400Gbps connections powered by four NVIDIA ConnectX-8 NIC chips on the underside.
Looking at the side of the server, you can see it is still a large box, but also that the front is mostly dedicated to storage with the CPUs at the back.
In this case, the two Intel Xeon CPUs are also liquid-cooled.
Like many new generations of systems, the memory is liquid-cooled as well.
Here is a quikc looks at the front slots.
Because components like the SSDs are not liquid-cooled in this design, there are still fans. Three years ago, we would have called this a liquid-cooled system. Now, perhaps it is a hybrid system since air is still being used to cool many of the components.
The top portion actually flips up, and underneath, there is a new setup with an internal liquid-cooling manifold and a locking mechanism.
The new setup is really slick. At GTC 2026, it was fairly clear that these were new products, and there is still a bit of development work that needs to happen, but this is a neat direction. One reason is that it is very different from the more traditional air-cooled versions.

Gigabyte also had its more traditional NVIDIA RTX Pro 6000 Blackwell air-cooled platfrom on display.
Instead of E1.S, we get U.2 storage on the front of this one along with many fans.
In the rear, you can see the difference. Here are the eight NVIDIA RTX Pro 6000 Blackwell Server Edition GPUs with their double-width heatsinks and power cables. In the distance, you can see the new liquid cooled-version where the GPUs are single-width and the GPUs plug directly into the liquid-cooling and power.
We have looked at a number of these air-cooled PCIe GPU systems previously, and the new liquid-cooled version looks really neat.
On the air-cooled GPU side, there was another option as well.
NVIDIA RTX Pro 4500 Blackwell
The NVIDIA RTX Pro 4500 Blackwell is a 32GB card designed for lower-cost servers.
We got to look at the new PCIe card in Gigabyte’s booth.
The front and back are relatively plain. If you are wondering what that bracket is at the end, that is a retention bracket to ensure the cards stay in their PCIe slots.
You can see the air cooler and the power connector.
Something very interesting is that this card did not have DisplayPort outputs like the RTX Pro 6000 Blackwell Server edition.
The advantage is that this is a single-slot GPU.
Next, let us get to Gigabyte’s NVIDIA GB300 AI Station.
