Terms used on this page (8)
- Nits
- A unit of screen brightness (candela per square metre). Typical, HDR and outdoor peak figures are measured under different conditions.
- Refresh rate (Hz)
- How many times per second the display can redraw the image.
- mAh and Wh
- Battery capacity. mAh is charge; Wh also accounts for voltage, so it is the more comparable energy figure across device types.
- Wi-Fi 6E / Wi-Fi 7
- Wi-Fi 6E adds the 6 GHz band to Wi-Fi 6; Wi-Fi 7 (802.11be) adds wider channels and multi-link operation. Real speeds depend on the router and network.
- NPU and TOPS
- The NPU is the chip's AI accelerator; TOPS is the manufacturer's quoted peak throughput and is not directly comparable across chip makers.
- OLED
- A display whose pixels emit their own light, so black areas can be fully dark; LCDs use a separate backlight.
- LPDDR and UFS
- LPDDR is a mobile memory (RAM) standard and UFS a flash storage standard; higher version numbers are newer generations.
- Thunderbolt / USB4
- USB-C connection standards for high-speed data, external displays and charging.
