Both leading foundries allowed customers to claim they were using a 4nm process when, in fact, they were using 5nm technology. This situation renders node names meaningless. Featured in our July 22 Microprocessor Report we are making this available, in full, for a limited time.

Overly cautious about rising development costs and risk, vendors aren’t refreshing their lower-cost processors, hurting themselves and customers. They must consider business cases other than merely chasing the biggest customers.

A research team led by Enlightra’s founders demonstrated a new method of photonic AI inference that is smaller than earlier photonics implementations. Using photonics also provides opportunities for resource sharing that aren’t available with electronics.

Our die-photo analysis reveals that the Dimensity 9000 features the smallest Cortex-X2 design, but Apple’s Avalanche CPU still leads in performance and power efficiency.

New ConnX 110 and 120 DSP cores upgrade the company’s BBE DSPs and are compatible with the higher-performance ConnX B10 and B20. They target wireless communications, radar, and lidar.

NXP is unifying its microcontroller offering with the new MCX family. Although this doesn’t indicate the end of the older families, it will be the focus for new designs that need modern features.

Both leading foundries allowed customers to claim they were using a 4nm process when, in fact, they were using 5nm technology. This situation renders node names meaningless.

RISC-V International, the governing body of the open-standard instruction set, recently approved four new specifications that address multiplication, bootloaders, and debugging, reducing the gap with Arm.

Imagination Technologies has unveiled its first Catapult family member. Based on the RISC-V architecture, the CPU core targets real-time applications, putting Cortex-R52 in its sights.

In the latest round of MLPerf Training results, Graphcore’s Bow offers a modest improvement and Habana’s Gaudi2 triples performance over its predecessor, vaulting past Nvidia’s A100 on one benchmark.

New Intel Atom processors have 4 to 24 CPUs and target enterprise networking and SMB storage. They extend the Snow Ridge product line and largely replace the Denverton family.

AlphaICs is sampling a test version of its Gluon edge-inference accelerator chip. Given moderate performance, the company plans changes to improve the production version, with an architectural overhaul planned for the second generation.
