How many years a graphics card physically lasts, how long it stays fast enough for games, which parts wear out first, and how to extend its life.

Learn how to check for a CPU or GPU bottleneck using GPU usage, a resolution test and PresentMon, why bottleneck calculators mislead, and 8 ways to fix it.

How to see what graphics card you have: Task Manager, Device Manager, dxdiag, System Information, macOS About This Mac and Linux lspci. 7 quick methods.

CPU vs GPU: a CPU has a few powerful cores for general tasks, a GPU has thousands of smaller cores for parallel work like graphics and AI. Full comparison.

Integrated vs discrete graphics: integrated GPUs share system RAM inside the CPU, discrete graphics cards have their own VRAM and far more power. Compare performance, cost and use.

Shared GPU memory is system RAM Windows lets the GPU use when VRAM runs out, usually up to half of your RAM. Learn how it works and whether you can change it.

NPU vs GPU: an NPU is a low-power AI accelerator for on-device tasks, a GPU is a powerful parallel processor for graphics and heavy AI. Compare TOPS, power and uses.

GPU performance chart for 2026: RTX 50, Radeon RX 9000 and Intel Arc cards ranked by tier, with VRAM, power, MSRP and current street price. Updated October 2026.

Streaming uses both CPU and GPU. See which one does more work in OBS, how NVENC and AMF encoders cut CPU load, and what hardware you need to stream smoothly.

Most GPU fans blow air down into the heatsink, not out of the card. Learn how open-air and blower coolers move air, and how to set up case airflow for lower temps.
