Laptops in Computing: articles, explanations and technology developments with context and verified sources.
TGP determines the real-world performance of mobile GPUs. Learn how it differs from TDP, how it affects a laptop chassis, and how to check the assigned power limit before you buy.
RTX Spark combines a Grace CPU, Blackwell GPU and unified memory in Windows laptops built on Arm architecture. The approach could make local AI workloads that require substantial memory easier to run, but headline specifications alone cannot predict performance, battery life or compatibility on every system.
TDP, processor architecture, and GPU help narrow down consumption, but they do not predict battery life on their own. Which data to compare and which tests to look for before buying.
Compatibility is not determined by the processor name or a single product listing. This guide explains how to review Windows 11 requirements, use Microsoft’s tools, and distinguish operating-system support from the support provided by the laptop manufacturer.
What PCIe 5.0 and NVMe do—and do not—offer in laptops, how to check M.2 compatibility, and what the available documentation actually says about power management and TRIM. Choose based on the specifications of the computer and SSD, not just the generation.
CAMM2 is the new JEDEC standard for notebook memory modules. It arrives in two families — DDR5 CAMM2 and LPDDR/LPCAMM2 — and enables thinner designs, higher frequencies and, in many systems, brings back user‑replaceable RAM without reverting to SO‑DIMM limitations. Here’s what you need to know to choose and upgrade with confidence in 2026.
In 2026, memory affects the bandwidth available to the iGPU and NPU, maximum capacity and upgrade options. We review LPDDR5X and LPDDR6, DDR5 SO-DIMM, CAMM2 and on-package memory, and explain what to check before buying.
Which tasks use CPU, GPU, and NPU; how TOPS, RAM/VRAM, and unified memory matter; and what practical limits quantization and model size impose for running local AI on Windows, macOS, and Linux in 2026.
