Cerebras doubled the existing wafer's clock instead of a new chip
Instead of building a new chip, Cerebras has introduced the CS-4 Nexus system, which doubles the performance of its existing WSE-3 wafer by running it at 2.8 gigahertz rather than 1.4 gigahertz. The rack combines three power shelves with three compute backpacks, delivering three times the compute of previous machines while using 50 per cent fewer components. The wafer input-output module now includes six Ethernet ports for direct wafer-to-wafer connections. Cerebras claims early access is open to selected customers, with general availability planned for later in the third quarter.[1]
Ambiq starts shipping two low-power chip families
For smaller devices, Ambiq has begun selling the Apollo330 Plus and Apollo510 Lite chip families through its own store and authorised distributors. Both families build on Arm Cortex-M55 cores running at up to 250 megahertz, featuring Helium vector extensions for signal processing and on-device inference. The target devices include battery-powered wearables, hearables, augmented-reality headsets, and digital health monitors. Security is handled by the company's secureSPOT 3.0 architecture with Arm TrustZone, though no specific customer designs were named at launch.[2]
A phone on the car's data bus coached the driver within a second
Hardware integration reached the track as Formula E and Google Cloud wired a Pixel 10 Pro directly to the CAN bus of a GEN4 car. The smartphone ran a Gemma model locally while talking to Gemini in the cloud, feeding time loss, traction, and balance data into the driver's earpiece within about a second. The demonstration took place during a hillclimb event, showing how analysis can be moved closer to the driver, though a full season of use would be required to evaluate its durability.[3]
