Gaming Laptop Glossary
The terms that actually change which laptop you should buy — explained in plain English, with what to look for in a 2026 RTX 50-series machine.
- Advanced OptimusNVIDIA's automatic, no-reboot MUX that switches between the iGPU and discrete GPU on the fly.
- Arrow Lake-HXIntel's Core Ultra 200HX-series, the high-performance mobile CPUs powering many 2025-2026 flagship gaming laptops.
- Coil WhineA high-pitched electrical noise from a laptop's power components, most noticeable at very high frame rates.
- DLSS 4NVIDIA's AI upscaling suite for RTX 50-series laptops, adding Multi Frame Generation and a transformer-based image model.
- Dynamic BoostNVIDIA tech that shifts spare power between the CPU and GPU in real time to add extra GPU wattage when gaming.
- G-SYNCNVIDIA's variable refresh rate tech that syncs the display to the GPU to eliminate screen tearing and stutter.
- GPU TGPThe wattage a laptop feeds its GPU; higher TGP usually means more performance from the same GPU model.
- IPSA common LCD panel type offering wide viewing angles and accurate color, but weaker contrast than OLED or Mini LED.
- Liquid MetalA gallium-based thermal compound that conducts heat far better than paste, lowering CPU and GPU temperatures.
- Mini LEDAn LCD backlight made of thousands of tiny LEDs in local-dimming zones for very high brightness and deep blacks.
- Multi Frame GenerationA DLSS 4 feature exclusive to RTX 50-series GPUs that inserts up to three AI-generated frames between rendered frames.
- MUX SwitchA hardware switch that routes the discrete GPU straight to the display, bypassing the iGPU to boost gaming frame rates.
- OLEDA self-lit display tech with perfect blacks and per-pixel contrast, prized for image quality on premium gaming laptops.
- OLED vs Mini LEDHow to choose between OLED's perfect blacks and per-pixel contrast and Mini LED's higher brightness and no burn-in.
- Panther LakeIntel's Core Ultra 300 mobile CPUs built on the 18A process, launched at CES 2026 with big efficiency and battery gains.
- RTX 5080 vs RTX 5090The laptop RTX 5090 adds 24GB VRAM and ~37% more cores than the 5080, but shared power limits narrow the real gaming gap.
- Soldered vs SO-DIMM RAMWhether a laptop's memory is fixed to the board (soldered) or installed in upgradeable SO-DIMM slots.
- Thunderbolt 5Intel's latest port standard: 80 Gbps two-way (up to 120 Gbps for displays) plus up to 240W charging over USB-C.
- Vapor ChamberA flat sealed cooling chamber that spreads GPU and CPU heat over a wide area for better sustained performance.
- Wi-Fi 7The latest Wi-Fi standard (802.11be), adding wider channels and Multi-Link Operation for faster, lower-latency wireless.
