When CPUs first started coming out, and for many years after, they could only execute one set of instructions at a time. After awhile, interfaces were built to support having multiple CPUs running at the same time to increase the horsepower of a machine. These CPUs had distinct packaging still, but now the computer as a whole could execute a set of instructions per CPU.
CPU manufacturers started placing multiple CPUs in one distinct package and also included the interface for the CPUs to talk within this package. So even though you had one product, it could execute multiple instructions at one time. Core is a marketing term to let people know the number of independent sets of instructions that a single CPU package can execute.
What else can I help you with?
Multiply by 2 for dual core?
That can either mean a dual-socket machine with dual-core CPUs (two CPUs with two cores each) or a quad-core CPU (one CPU with four cores).
What are the different types of CPUS?
Too many to even begin to list here, forget describing the architectures.
How do operating systems handle Multi-core CPUs?
They are treated exactly like two separate CPUs. Any operating system that can use multiple CPUs can also use a processor with multiple internal cores, with no changes needed to the code.
In a coumpter what is known as the core?
The central processing unit (CPU). In the past, CPUs used to only have 1 core, but with the multiple cores in computers now, it is like having multiple CPUs.
What is Lower power processor?
The one with the lower mhz or ghz. Depending on the number of cores (newer cpus) this can vary.
What is AMD x2?
AMDs 'dual core' CPUs, those that contain 2 CPU cores, as opposed to the 1 CPU core found in earlier AMD (and intel, VIA, cyrix etc) CPUs. Dual core CPUs have much better multitasking performance than traditional single core CPUs.
Does the AMD Phenom II X4 955 have 4 cores?
Yes, the AMD Phenom II X4 955 is a quad core processor meaning that this processor has four cores or CPUs.
What is a Intel core?
Nowadays the CPU's could have more than one core - they may have 2, 4 cores. Of course there still are CPUs with one core and they are called single core processors.
What is a single core Intel?
Nowadays the CPU's could have more than one core - they may have 2, 4 cores. Of course there still are CPUs with one core and they are called single core processors.
What is the concept of processor affinity?
In a multicore or multi-CPU system, processor affinity refers to what cores or CPUs a given process can run on. The application can be forced to prefer some cores or processors over others.
What is the name of thememory cache that is shared by cores in a multi core processor?
Most modern (post-2000) CPUs used shared multi-level caches. The level of sharing a specific cache can vary by the design of the processor. For example, many CPUs will share Level 1, Level 2, and Level 3 caches between all cores. In others (particularly those with many cores), Level 1 and possibly Level 2 caches may be shared only between a certain subset of cores. For example, in certain 16-core CPUs, the design breaks it into 8 sets of 2 cores - each pair shares a L1 cache (8 L1 caches total), with 2 pairs sharing a L2 cache (4 L2 caches total), and all cores sharing a single L3 cache.
Why you use core word with recent microprocessor?
Cores are basically the amount of CPUs packed into one CPU. So say, the dual-core (2 core) CPUs have the power of 2 cpu's packed into one unit. Originally, they just had the single-core CPUs, but recently, they've created the dual-core, tri-core, quad-core, and six-core CPUs. Hope this helps! SeanHolshouser
