For instance, a quad-core processor may support a clock speed of 3. So, if you have a single-threaded program, the dual-core processor is indeed more efficient. When multiple cores work concurrently on instructions, at a lower rate than the single-core, they achieve an immeasurable processing rate.
Multi-core processors produce high-performance computing HPC. HPC will take complex computations and break them into smaller pieces. Using software, each piece of the computation can then be solved by multiple CPU cores. Think of it as taking a supercomputer and breaking it down into smaller, more manageable building blocks that can then be used to solve complex scientific problems.
HPC can therefore enable users to manage difficult tasks at relatively lower energy, which is a significant factor in devices like laptops, mobile phones or laptop, which run on batteries. This kind of energy saving — and ultimately cost saving — is one way in which your business could benefit. If your business deals with virtualisation, databases and the cloud then multi-core processors could also be for you. Most computer graphic rendering software, for instance, needs a rendering engine to show what occurs in an animation.
A type of artificial intelligence manages characters, simulations and events in a virtual environment. Using a single core, all of events these must work by alternating between each process. Multi-core processing is essential to get these instructions to work without jitter or extremely long process times.
This is not only the case with virtualisation. If you work with video, video encoding programs will see substantial benefits because single-frame rendering can go into individual cores and then merge into a stream via the multi-core process. For database management, scientific analysis or anything that requires processing huge volumes of data at high speeds, HPC, enabled by multi-core processing, is also essential.
Most computers only have a single CPU. Before hyper-threading and multi-core CPUs came around, people attempted to add additional processing power to computers by adding additional CPUs. This requires a motherboard with multiple CPU sockets.
Even a high-powered gaming desktop with multiple graphics cards will generally only have a single CPU. The more CPUs or cores a computer has, the more things it can do at once, helping improve performance on most tasks. Intel CPUs also feature hyper-threading, which is kind of a bonus.

A core can work on one task, while another core works a different task, so the more cores a CPU has, the more efficient it is.
You should shoot for at least four cores in your machine if you can afford it. Some apps take better advantage of multiple threads than others. Lightly-threaded apps, like games, don't benefit from a lot of cores, while most video editing and animation programs can run much faster with extra threads. And the numbers you see in an Intel Core or otherwise processor is not a direct correlation to how many cores the CPU has.
