Understand every spec before you buy
Gaming PC Glossary
Learn what every gaming PC term actually means and how it affects your FPS, temps, and in-game experience. We explain specs and technologies in simple language, so you can choose the right build with confidence.
Featured topics
DLSS
AI upscaling that boosts FPS by rendering at lower resolution while keeping sharp visuals.
Ray Tracing
Lighting technology that simulates realistic reflections and shadows for more immersive graphics.
Bottleneck
A weak component that holds back the rest of your system and limits overall FPS performance.
DDR5
New‑generation system RAM with higher speeds and bandwidth for modern CPUs and games.
NVMe SSD
High‑speed storage that drastically cuts game load times compared to SATA SSDs and HDDs.
VRAM
Dedicated video memory on your GPU that stores textures and assets needed to render frames.
FPS
Frames per second — the main metric that shows how smooth and responsive your gameplay feels.
Input Lag
Delay between your mouse/keyboard actions and what you see on screen during gameplay.

Frequently Asked Questions
This glossary is a collection of short, plain‑language explanations for the most important PC hardware and gaming terms.
Instead of dry textbook definitions, every entry focuses on what the term means in real games and how it affects your experience (FPS, visuals, latency, noise, and thermals).
Each term explains not only “what it is”, but also “how it works” and “why it matters when you’re buying or upgrading a PC”.
You’ll see how things like CPU, GPU, RAM, VRAM, SSDs, and cooling interact — so you can understand bottlenecks, match components correctly, and avoid paying for specs you won’t actually use.
We write each page so a complete beginner can follow it, but still include enough detail for enthusiasts comparing specs.
If you’re new to hardware, start with basics like CPU, GPU, RAM, FPS and refresh rate; if you’re more experienced, dive into DLSS, Ray Tracing, 3D V‑Cache, PCIe 5.0 and other advanced topics.
No. The core ideas behind PC hardware and gaming technologies are the same regardless of the brand.
The difference is that we explain everything through real use cases — competitive FPS, high‑refresh gaming, 4K, streaming, and future upgrades — so you can map the theory directly to your next build.
A regular dictionary usually stops at “what it is”. Here, every term also covers how it works, what trade‑offs it has, and when it actually matters for gaming.
The goal is that after reading a term, you know whether you should change your config (and what exactly to change) to get more FPS, lower temps, lower noise, or smoother input.
If a word or abbreviation isn’t in the glossary yet, you can still use related terms to understand the basics — for example, by reading about different types of memory, storage, or cooling.
You can also contact Hypercyber support or suggest a term you’d like us to add, and we’ll include it in a future update of the glossary.
