What are CPU cores? The number of Cores on a CPU of course…
When the processor was first developed, it only had one processor core. Every task the computer performed was handled on this single processor core. But as technology developed, computer manufacturers brought us multi-core processors.
Number of nuclei identified:
2 dual cores
4 Quad-Core cores
6 Hexa-Core cores
8 Octa-Core cores
What is the highest number of cores currently?…
Ryzen will launch its Threadryper 3990X in 2020 with 64 cores!
So how does it work?
To make things simple:
– Each Core is seen by the computer as its own processing unit.
– At first, manufacturers tried to install multiple processors on a single motherboard, but it was expensive, not to mention the latency problem.
– The CPU is capable of distributing the work on an individual Core:
– Core 1: Photoshop
– Core 2: Premiere Pro
– Core 3: Google Chrome
– Core 4: Spotify
But what happens if you have more programs open than cores?
Is your computer going to explode? No, it won't explode.
When you load a program (Photoshop), a “process” is created. This process is assigned its own:
– Memory (RAM) and identification information (i.e. a serial number).
– The system will assign this process to a Core. If there are no cores available, the core will be virtually split into one of the core threads.
– I talk more about Threads in another video.
– If there are no cores or threads available, the process waits for its line in the queue until it is called to action.
So more cores, faster computer, right?
Not necessarily. There are several reasons why core count alone is not enough to create a faster processor. Here are some things to consider when choosing a processor:
– MHz
– Son
– Instructions per cycle (IPC)
– Watts
All this and much more to come…
