When do i need hyperthreading

It's the main difference between the Core i5 and i7, and that many games don't use it explains why i5s power some serious gaming rigs. If you've been considering an upgrade but you're not sure if you need Hyper Threading, this video from Techquickie will help.

Strictly speaking, Hyper-Threading is best applied to operations and applications where multiple tasks can be intelligently scheduled so there's no idle time on your processor.

Tasks like video editing, 3D rendering, and heavy multi-tasking are great examples. Similarly, Hyper Threading can help a CPU push light tasks like background applications or browser windows to one processor, while heavy applications like games or full-screen video goes to another.

Today, quad-core CPUs are pretty much the mainstream configuration. It basically means that one CPU core can work on two problems at the same time. Just that it can ensure all its capacity is used by dealing with multiple simpler problems at once.

To your operating system, each real silicon CPU core looks like two, so it feeds each one work as if they were separate. This is another question that can be a little complicated but is actually pretty simple when you break it down. Given that they are close to each other in single-thread, single core performance. Because the quad-core CPU has more physical processing hardware. Now our question really has to do with the software that you want to run.

Simply because none of the processing capacity is being wasted and the component is working near its full potential as much of the time as possible. Traditionally operations such as CPU 3D rendering, video encoding, and photo manipulation will create as many threads as your poor CPU can take.

In other words, many modern professional applications are thread-hungry. This is why Hyperthreading has been restricted to professional-tier CPUs such as the i7 and up. At the time of writing, in , the latest video game engines are starting to become more thread heavy.
