Qt Canvas Painter: Accelerated performance using paths

Qt Canvas Painter giới thiệu QCanvasPath và nhóm path nhằm tối ưu hiệu suất render 2D, tiết kiệm ~60% bộ nhớ nhờ định dạng SoA thân thiện cache, hỗ trợ tái sử dụng giữa các frame và tương thích API với QCanvasPainter. Nhóm path cho phép GPU lưu trữ đỉnh (vertex) tĩnh, giúp xử lý biến đổi, màu sắc hay gradient mà không cần cập nhật buffer, đồng thời chứng minh khả năng render tiến triển 60fps trên thiết bị nhúng với tải CPU/GPU thấp hơn. Tính năng này sẽ trở thành module chính thức trong Qt 6.12.

Lập trình viên muốn tối ưu hiệu suất rendering 2D trên Qt nên đọc bài này để khám phá cách sử dụng QCanvasPath và path groups để giảm chi phí CPU/GPU, giảm bộ nhớ và cải thiện trải nghiệm 60FPS trên thiết bị embedded.

AMD Contributes ONNX Runtime Backend To FFmpeg DNN Filter

An AMD engineer has contributed an ONNX Runtime backend to FFmpeg's DNN (Deep Neural Network) processing filter. The addition enables inferencing across multiple GPU and NPU platforms, including NVIDIA CUDA, Windows DirectML for all major GPU vendors, and AMD Ryzen AI NPU support via the ONNX Runtime VitisAI execution provider. This marks AMD's effort to make the Ryzen AI NPU useful within FFmpeg workflows.

What's New in WebGPU (Chrome 149-150)

Chrome 149-150 bổ sung hai tính năng WebGPU quan trọng: Immediates (push constants/root constants) cho phép truyền dữ liệu nhỏ, thay đổi thường xuyên trực tiếp vào shader qua WGSL <immediate> và API setImmediates(), tối ưu hiệu suất bằng cách bỏ qua tạo buffer GPU. Đồng thời, quy tắc validation chặt chẽ hơn với transient attachments, yêu cầu viewFormats rỗng khi tạo texture tạm thời và hạn chế thay đổi usage flags trong createView().

Lập trình viên nên đọc bài này để cập nhật cách tối ưu hóa hiệu suất rendering bằng Immediates trong WebGPU, giúp giảm chi phí CPU-GPU và xử lý dữ liệu thay đổi thường xuyên trên mỗi vẽ hình, đồng thời nắm rõ các quy tắc mới về transient attachments để tránh lỗi và bảo đảm tính ổn định trong ứng dụng.

Sail raises $80M to make AI agents cheaper to run

Sail Research has raised $80M in combined seed and Series A funding at a $450M valuation to reduce the cost of running long-horizon AI agents. Founded by ex-Apple and ex-NVIDIA engineers, the company claims its inference engine delivers up to 10x lower cost per token than rivals by optimizing for throughput rather than latency. Sail also offers 'Sailboxes,' sandboxed environments that only charge for active agent compute time. The startup topped the BrowseComp-Plus benchmark at 90.72% accuracy and already has paying customers. The round was led by Sequoia and Kleiner Perkins, with notable angels from Anthropic, OpenAI, and Alphabet.

Nvidia accidentally made the RTX 50 series feel like a beta test for the RTX 60 series

The RTX 50 series launched with headline features like Multi Frame Generation, Ray Reconstruction, and Neural Texture Compression that were either unfinished or lacked broad software adoption. Months after launch, major fixes and updates are still arriving, and the most compelling exclusive features primarily benefit 4K gaming — a niche most PC gamers don't occupy. RTX 40-series owners already receive the biggest DLSS 4.5 image quality improvements, leaving the 50 series in an awkward middle ground. The author argues the generation feels like a transitional stepping stone, with the upcoming RTX 60 series (Rubin) positioned to be the hardware that fully realizes Nvidia's long-term rendering ambitions.

The Download: Europe’s heat wave hits the grid, and IBM’s chip targets Moore’s Law

MIT Technology Review's daily briefing covers several major stories: IBM has unveiled a prototype chip with ~100 billion transistors on a fingernail-sized area, doubling transistor density from 2021 and potentially extending Moore's Law by building transistors upward rather than shrinking them. Europe is experiencing a record heat wave straining power grids, with some plants offline during historically planned maintenance windows. Anthropic has accused Alibaba of illicitly extracting Claude's capabilities via model distillation, calling it the largest known distillation attack. OpenAI and Broadcom revealed their first jointly designed AI chip called Jalapeño. Additional items cover the EU joining a US pact against Chinese AI, data center-driven inflation in memory chips, and companies struggling to control AI token spending costs.

IBM claims major chip breakthrough

IBM has announced the world's first sub-1nm chip technology, dubbed the 0.7nm (7-angstrom) node. The breakthrough uses a new transistor design called 'nanostack,' which stacks transistors in three dimensions rather than laying them flat. The result is nearly 100 billion transistors on a fingernail-sized chip — roughly twice the density of IBM's 2nm chip from 2021 — delivering up to 50% higher performance or 70% greater energy efficiency. IBM says commercial production could begin within five years, though no manufacturing partner has been announced yet. The news comes as chipmakers race to meet the growing compute demands of AI workloads, with Intel also recently advancing its 1.8nm 18A process.
