Visual Look Up on Apple Silicon Macs: A Power and Energy Analysis

2025-09-06

This study analyzes the power and energy consumption of a single Visual Look Up (VLU) on Apple silicon Macs using Powermetrics and LogUI. Results show that the CPU performs the vast majority of the work (93%), with the GPU and Neural Engine (ANE) contributing only 4.6% and 2.2% respectively. While the ANE contributes to performance improvements during model execution, its overall energy consumption is low. The conclusion is that VLU, despite its impressive functionality, is not particularly demanding on the hardware.

Disk I/O Beats Memory Caching? A Surprising Benchmark

2025-09-05

Conventional wisdom dictates that memory access is far faster than disk I/O, making memory caching essential. This post challenges that assumption with a clever benchmark: counting the number of tens in a large dataset. Using an older server and optimizing code (loop unrolling and vectorization), along with a custom io_uring engine, the author demonstrates that direct disk reads can outperform memory caching under specific conditions. The key isn't that the disk is faster than memory, but rather that traditional memory access methods (mmap) introduce significant latency. The custom io_uring engine leverages the disk's high bandwidth and pipelining to mask latency. The article emphasizes adapting algorithms and data access to hardware characteristics for maximum performance in modern architectures, and looks ahead to future hardware trends.

Intel Patents 'Software Defined Supercore': A Single-Threaded Performance Boost?

2025-09-01

Intel has patented a technology called 'Software Defined Supercore' (SDC) designed to significantly improve single-threaded performance. SDC fuses multiple physical cores into a virtual 'supercore' by dividing a single thread's instructions and executing them in parallel. Specialized instructions maintain program order, maximizing instructions per clock (IPC) without increasing clock speed or core width. While currently just a patent, if successful, SDC could dramatically enhance single-thread performance in select applications on future Intel CPUs. The technology tackles the limitations of building extremely wide cores by using software and a small hardware module to manage synchronization and data transfer.

USB-C Power Delivery: A Negotiation of Power Modes

2025-09-01

USB-C power delivery isn't a simple pass-through; it's a sophisticated negotiation. The source first broadcasts its supported voltages, current limits, and features (including optional PPS mode, allowing the sink to fine-tune voltage and current). The sink selects a mode and sends a request. The source assesses and decides to accept or reject. Upon acceptance, the source prepares the power and sends a ready signal. The sink also sends acknowledgements. Furthermore, Vendor Defined Messages (VDMs) negotiate data direction and other information; their openness determines whether they're good or bad.
