Today we are taking a look at a network-focused industrial mini-PC from Qotom, the Q51551UT. The small box goes big on networking, with 10 Ethernet ports that support data rates as high as 10Gbps The post Qotom Q51551UT 4x 10GbE and 6x 2.5GbE Mini PC Review appeared first on ServeTheHome.
Chip Scaling Moves Beyond The Transistor
SEMICON West 2026: Advanced packaging, photonics, test, and AI are increasingly intertwined; very different conversations ahead. The post Chip Scaling Moves Beyond The Transistor appeared first on Semiconductor Engineering.
Green Light: Carbon-Aware Design of Photonic Transformer Accelerators at the Edge
Migrating transformer inference to the edge requires sustainability considerations that encompass both operation and manufacturing, rather than operational energy alone. Silicon photonics enables high-bandwidth, low-energy matrix multiplication; however, existing microring-resonator-based Dot Product Unit (DPU)…
Agentic AI for Heterogeneous System Design Across Chip, Scale-Up, and Scale-Out Domains
The design space of modern AI/HPC systems has expanded rapidly across compute architectures, including GPUs, dataflow processors, and RISC-V accelerators; memory tech- nologies, including HBM, GDDR, and SRAM; and interconnects such as NVLink, UALink, Infinity Fabric, InfiniBand, Slingshot, and Ultra Ethernet. No…
Faster is Better // The Silicon Notebook E4
I walk the show floor at TSMC's Open Innovation Platform (OIP) event in the Bay Area. It's a one-day conference where TSMC puts its partners front and centre. We stop by Cadence, Samsung, SK hynix, Synopsys and GUC to see what's next for HBM thermals, co-packaged optics, UCIe 2.0 and AI-assisted chip design. If you've…
The GenAI Boom Accelerates And Transforms Ethernet Switching
The Next Memory Frontier // The Silicon Notebook E3
We're at the final day of the AI Infrastructure Summit, and the booths come down around me as I walk. You get Dnotita's vector database ASIC back from the fab, SK Hynix mocking up high bandwidth flash, Marvell showing photonics, and a 30 watt box running 120 billion parameters for 2,100 dollars. Ruby Goodall, who runs…
