Teardown: AMD Radeon HD 7970 graphics card

January 31, 2025 By Martin Rowe 3 Comments

Identifying the components reveals clues as to how a graphics card works, assuming you can read the identifying marks and find documentation. Wandering through an electronics swapfest, I found someone selling a graphics card and wondered what was inside. I bought it for $20, opened the case, and looked up the architecture and components. Released […]

PCIe switch routes automotive data traffic

January 24, 2025 By Martin Rowe Leave a Comment

The Switchtec family of PCI switches from Microchip move data around a vehicle’s “data center.” With vehicles becoming more software-centric, their computing power relies on a central processor that manages other processors, often on a single board. PCI Express (PCIe) becomes the bus that transports all that vehicle data. The PCI100x Switchtec PCIe switches from […]

Future connected car

IEEE 802.3cg defines these two Ethernet flavors, which deliver data and power over a single pair of wires. In 2019, IEEE published 802.3cg, which added clauses 146 and 147 to its Ethernet 802.3 standard, which created 10Base-T1S (short reach) and 10Base-T1L (long reach). These two Ethernet flavors can serve vehicles and industry, respectively, where few […]
