3.5-inch SBC features Comet Lake-S
Apr 9, 2021 — by Eric Brown 1,524 viewsAaeon’s 3.5-inch Linux-ready “GENE-CML5” SBC supplies an up to octa-core 10th Gen Core CPU plus up to 64GB DDR4, 2x SATA, 2x GbE, 2x USB 3.2 Gen2, DP, VGA, M.2 M-key, and PCIe x4.
Aaeon has posted a preliminary product page for what appears to be the first 3.5-inch SBC built around Intel’s 10th Gen Comet Lake-S. In fact, this is one of the first Comet Lake SBCs of any kind, following a few early entries like Portwell’s WADE-8212 Mini-ITX board.

We often spend a lot of time searching for story ideas that do not otherwise show up in announcements, tips, or filters. Yet, we easily found the GENE-CML5 hiding in plain site on our advertising column. We pride ourselves in our strict separation between edit and advertising at LinuxGizmos, but we should probably spend a little more time checking out those colorful little boxes on the side of the page.
Intel’s Comet Lake-S, which is related to more power-efficient, 15W TDP Comet Lake-U CPUs, falls between 8th and 9th Gen Coffee Lake-S and the new 11th Gen Rocket Lake-S, which is likely the last of the fully 14nm-fabricated Intel Core platforms. Comet Lake-S offers incremental improvements to power efficiency, thermal packaging, cache, and performance, including overclocking enhancements. It is the first Core platform to offer hyperthreading on all the parts.

Aaeon is not supporting the 10-core models, but it offers five 35W TDP selections: an octa-core Core i7-10700TE (2.0GHz/4.4GHz), a hexa-core i5-10500TE (2.3GHz/3.7GHz), and a quad-core i3-10100TE (2.3GHz/3.6GHz). There are also two dual-core options: the 3.2GHz Pentium Gold G6400TE and the 3.0GHz Celeron G5900TE. Linux and Windows are mentioned in passing in the manual.

The GENE-CML5, which is not to be confused with the CML5 gene, follows earlier Aaeon 3.5-inchers such as its Whiskey Lake based GENE-WHU6. The SBC ships with up to 64GB DDR4 and offers dual GbE ports. Storage is available via dual SATA III interfaces and the M.2 M-key slot. There is also a PCIe x4 header.
