ASRock Rack is a subsidiary of ASRock that deals with servers, workstations, and other data-center hardware, and comes with the enormous brand trust not just of ASRock, but also the firm hand of parent company and OEM giant Pegatron. At the 2024 Mobile World Congress, ASRock Rack introduced several new server innovations relevant to the AI Edge, and 5G cellular carrier industries. A star attraction here is the new ASRock Rack MECAI-GH200, claimed to be the world's smallest server powered by the NVIDIA GH200 Grace Hopper Superchip.

The ASRock Rack MECAI-GH200 executes one of NVIDIA's original design goals behind the Grace Hopper Superchip—AI deployments in an edge environment. The GH200 module combines an NVIDIA Grace CPU with a Hopper AI GPU, and a performance-optimized NVLink interconnect between them. The CPU features 72 Arm Neoverse V2 cores, and 480 GB of LPDDR5X memory; while the Hopper GPU has 132 SM with 528 Tensor cores, and 96 GB of HBM3 memory across a 6144-bit memory interface. Given that the newer HBM3e version of the GH200 won't come out before Q2-2024, this has to be the version with HBM3. What makes the MECAI-GH200 the world's smallest server with the GH200 has to be its compact 2U form-factor—competing solutions tend to be 3U or larger.ASRock Rack is also showing off its latest barebones servers and motherboards for Intel, AMD, and Ampere processors. The SIENAD8UD-2L2Q server motherboard is designed for small business server roles, and supports AMD EPYC 8004 "Sienna" processors. MEC2U-SIENA is a 2U barebones server built around this. Also showcased are the 4U18N-AM5/2T (4U workstation/server based on Socket AM5 for Ryzen and Ryzen PRO), 1U10E-ALTRA/1L2T (1U based on the Ampere Altra), the ALTRAD8UD-1L2T server motherboard, GENOAD12M3-2Q 2P AMD EPYC 9004 "Genoa" server motherboard, SPC741D8-2L2T (LGA4677 server motherboard for 4th- and 5th Gen Xeon Scalable "Sapphire Rapids" and "Emerald Rapids,") and SP2C741D16-2T, a 2P LGA4677 server motherboard for "Sapphire Rapids" and "Emerald Rapids."
