Hyper-Threading Explained: Logical vs Physical CPU Cores
Ever wondered why your 4-core CPU shows 8 threads in Task Manager? 🤔
In this video, we break down Intel's Hyper-Threading Technology (also known as Simultaneous Multithreading or SMT). We explain the crucial difference between Physical Cores and Logical Cores and how your computer uses 'downtime' to get more work done.
We use simple analogies, like a chef in a kitchen 👨🍳, to explain how a single processor can juggle multiple tasks without actually doubling the hardware. We also cover the realistic performance gains you can expect—spoiler: it's not actually double the speed! 🚀
If you are building a PC or just want to understand how computers work at a deeper level, this guide is for you.
