what do cores and threads do in a processor?

Cores increase the amount of work accomplished at a time, whereas threads improve throughput, computational speed-up. Cores is an actual hardware component whereas thread is a virtual component that manages the tasks. Cores use content switching while threads use multiple CPUs for operating numerous processes.

If your threads run on physical cores at the same time then they are parallel, otherwise they are just time-sharing or concurrent. Originally threading originated as an substitute for “forking” multiple child process from the parent process in order to share work load and complete the task concurrently.

Most of the modern games are well optimized to run on any number of cores. Specially if you are talking about pc games. But as most of the intel processors just come with two cores and hyper threading thus most game developers actually put emphasis on single core hyper threaded performance optimization.

The core count is the physical number of cores on the CPU die itself, whereas the thread count is the number of individual application threads which can be executing simultaneously on the CPU itself. Without any additional or special hardware, this is equal to the core count.

Multi threading improves performance by allowing multiple CPUs to work on a problem at the same time; but it only helps if two things are true: as long as the CPU speed is the limiting factor (as opposed to memory, disk, or network bandwidth) AND so long as multithreading doesn't introduce so much additional work (aka ...

Logical cores are the number of Physical cores times the number of threads that can run on each cores. This is known as HyperThreading. If I have a computer that has a 4-core processor, runs two threads per core, then I have a 8 logical processors. You can see your computers core capabilities by running lscpu command.

CUDA Cores are parallel processors, just like your CPU might be a dual- or quad-core device, nVidia GPUs host several hundred or thousand cores. The cores are responsible for processing all the data that is fed into and out of the GPU, performing game graphics calculations that are resolved visually to the end-user.

Dual-core processors arrived on the scene in 2005, and made a huge impact on computers and laptops. Having a multi-core processor means that computers are able to multitask much better, allowing you to run numerous applications and perform intensive tasks all at the same time.

A CPU, or Central Processing Unit, is what is typically referred to as a processor. ... A CPU (central processing unit) contains (1-many) cores. Each core can execute (1-many) threads depending on hyper-threading technology - it does the actual computation sort to speak.

Both Core i5 and Core i7 processors use Turbo Boost, with Core i7 processors generally achieving higher clock speeds. ... Hyper-Threading technology is used to increase performance on multithreaded tasks, letting each core address two processing threads at the same time instead of just one.

Do cores and threads matter for streaming at all? Higher clock speed per core = better game performance for CPU intensive games. Higher core count = better game performance for games designed and optimized for multi-core/multi-threaded systems.

In very basic terms... Do cores and threads matter for streaming at all? Higher clock speed per core = better game performance for CPU intensive games. Higher core count = better game performance for games designed and optimized for multi-core/multi-threaded systems.

Control unit and CPU. During the execution of a program, the control unit fetches one instruction at a time from the main memory and then executes it. ... CPU performs all types of data processing operations. It stores data, intermediate results, and instructions (program).

Today, CPUs have been two and 18 cores, each of which can work on a different task. 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.

A CPU's per core peformance is better in games, but in multi-threaded applications such as rendering then more cores will suit you better.

It means that the CPU has 2 physical cores but can process 4 threads simultaneously through hyper threading or Simultaneous multithreading (SMT). In reality, one physical core can only truly run one thread at a time, but using hyper threading, the CPU exploits the idle stages in the pipeline to process another thread.

A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
