There’s no mention of operating system support, but the company’s NUC Ultra 100 BOX/ NUCS Ultra 100 BOX Series based on the NUC Ultra 100 motherboards support Windows 10/11, and I don’t see why Linux would not be supported in due time.

Performance-wise there’s a 10% to 23% CPU performance improvement (Cinebench R23 multi-core) over previous generation Raptor Lake NUCs based on Intel Core i5-1340P and Core i7-1360P processors. But as noted in our article about ADLINK cExpress-MTL COM Express Type 6 Compact Meteor Lake module, the main advantage is the much faster internal GPU yielding 76% to 115% improvement in the 3DMark Time Spy benchmark. The new Intel AI Boost NPU will also enable new applications in “AI PC” and deliver 20 times the performance per watt.

ASRock did not provide availability and pricing for the NUC Ultra 100 Meteor Lake-H motherboards and related NUC BOX series. More details may be found on the product pages for the motherboards and mini PCs with the latter including the NUC BOX-155H and NUC BOX-125H models. There are also NUCS BOX-155H and NUCS BOX-125H with a different motherboard equipped with a single 2.5GbE port, no SATA port, and fewer USB ports.
