Gigabyte R1C7 K0A AS1 At Computex 2026 8x Node Sled
While we are out building fun clusters, Gigabyte is doing something really interesting. It has a 40-node cluster with 320 cores 1.28TB of memory, 80x SSDs, and 40 (integrated) GPUs in a single 1U chassis. We encountered Gigabyte’s hardware on display at Computex 2026, and it is quite neat.

The Here are the quick specs of the cluster. There are 40 Intel Core Ultra 7 258V (Lunar Lake) nodes, each with 32GB of LPDDR5X memory and two M.2 slots.
Gigabyte R1C7 K0A AS1 At Computex 2026 Specs<br>To understand the server, Gigabyte took almost GPU-looking cartridges and installed five of them in the server with three in front and two in the second row.
Gigabyte R1C7 K0A AS1 At Computex 2026 5x 8 Node Sleds And Power<br>Taking one of these cartridges out, you can see that there are eight nodes.
Gigabyte R1C7 K0A AS1 At Computex 2026 8x Node Sled<br>The nodes all come on a small board with relatively few connections to the overall system. Under one heatsink we have the Lunar Lake CPU. Under the other, we have two PCIe Gen5 x2 M.2 slots.
Gigabyte R1C7 K0A AS1 At Computex 2026 Intel Core Ultra 7 Processor 258V Node<br>Moving to the back of the system, this is where things are really neat. There is not a lot of information on this one, but it looks like each cartridge is getting two MCIO 8i connectors. Again, this is all speculation at this point since this is not in the specs shown. The big heatsink is at the rear is likely how all of this is consolidated to two QSFP28 ports at the rear.
Gigabyte R1C7 K0A AS1 At Computex 2026 Rear Connectivity<br>Inside, there is a chassis management controller, so there is a rear management port. We also get two 3.2kW Titanium rated power supplies. Most interesting, however, are the two QSFP28 ports.
Gigabyte R1C7 K0A AS1 At Computex 2026 Rear IO<br>Nobody we talked to knew how this was connected internally. If you look at the cartridge connectors, they do not have a huge number of pins for power and data. If those are MCIO connections, then with 16 lanes per cartridge, that is x2 per node. Alternatively, they could be carrying Ethernet, which would make this system really easy, since the chip under the big heatsink at the rear of the chassis would then be an Ethernet switch, and the topology would be extremely easy to manage.
Final Words
Overall, this is a neat system. It is also one that we could certainly see in the future. This is using Lunar Lake, so Patrick’s take on this:
"Companies have used Intel iGPU nodes in clusters for years, like the old Intel Visual Compute Accelerator, which was popular with a certain Indian Broadcaster, from what I remember. Intel Quick Sync transcoding is super easy to integrate, and you also get x86 cores for your pipeline. Alternatively, these designs have been used for physical desktop nodes in the data center and cloud."
Gigabyte’s R1C7-K0A-AS1 is not yet released, so hopefully we get to see more of it in the future. One fun and...
