What is the difference between a Core two core and a quad core processor, and how to distinguish it

At present, the core CPU type is divided into E series, Q series, T series, X series, P series, L series, U series, S series (the first letter of the model) E series is the dual-core CPU of ordinary desktop machines, with a power of about 65W Q series is a quad-core CPU, and the power will be 100W-150W T series is an ordinary notebook CPU, the power is 35W or 31W X series is Core 2 dual-core Extreme Edition, the power of the X series CPU of the notebook is 45W, and the CPU power of the X series of the desktop machine is about 100W The P series is the low-voltage CPU of the Centrino 5, the power is 25W The L series is the low-voltage CPU of the Centrino 4, the power of the 17W U series is the ultra-low voltage CPU of the Centrino 4, the power of the S series is a small package series, the power of the SL is 12W, the notebook of the SP is not yet on the market, and the power is unknown The front of some CPUs is QX, and the current QX series CPUs are all desktops, with a power of about 125W, and there will be a QQX9300 notebook CPU in the future, with a power of 45W

Upstairs is right, the i-series is that the i3 i5 is dual-core, and the i7 is quad-core.

Look at the model, the dual-core is the one that starts with e, such as E8400, and the 4-core is the one that starts with Q, such as Q8400

Correct the 2nd floor. The notebook i5 i3 is a dual-core i7 quad-core.

The i5 for desktop is 4-core i7 and 4 6 have.

A CPU is a processor, and quad-core refers to a processor based on a single semiconductor that has four processor cores with the same function. In other words, four physical processor cores are consolidated into a single core.

For CPUs, the main indicators that affect its performance are the main frequency, the number of bits of the CPU, and the cache instruction set of the CPU. The higher the number of bits of the CPU, the faster the CPU will perform calculations.

It is faster for a quad-core CPU to open four programs than a dual-core CPU to open four programs, and multi-core has a greater advantage in large data calculations (such as multi-threaded floating-point calculations used in tests).

The CPU is a processor and the answer is yes.

Quad cores are four processors, and that's a misconception.

Quad-core is a processor with four processing cores, dual-core is like a motorcycle two-stroke, quad-core is four-stroke.

The quality of the processor, first of all, we have to rely on whether the core architecture is advanced or not. The core architecture is advanced, and its performance is also relatively advantageous.

After that, it depends on the production process, such as 65nm old products and 45nm new products CPU have positioning, low-end, mid-range and high-end. The corresponding positioning is obvious in the performance of new and old products.

In the end, we pay attention to frequency and caching, and buy new electronic products instead of old ones

CPU is the meaning of processor.

Quad-core refers to having four physical cores in one processor.

The higher the frequency of a processor, the better the architecture, the more advanced the process, and the better the processor.

If it is a CPU with the same architecture, the higher the frequency, the better. Now the performance of the general quad-core is stronger than that of the dual-core. But it also has to be divided into platforms, and some of AMD's physical quad-cores can't do as much as Intel's dual-core quad-thread.

But generally from the ** can also roughly know their gap. If you want to choose AMD for cost performance, choose Intel for money.

The CPU is a processor, and the quad core is a processor with 4 cores inside. Good or bad depends on the computing speed, ability and heat.

(1) Check the computer processor.

Examples of common approaches to the number of cores:

1) View via Task Manager:

As shown in the following figure, open the "Task Manager":

As shown in the figure below, on the task manager, click "Performance" - "CPU" in turn, and you can see the number behind "Core" in the lower right part, this number is "Number of Cores", and then down, the number behind "Logical Processor" is "Number of Threads", for example, the CPU in the following figure is four cores and eight threads.

2) Third-party software "CPU-Z" view:

As shown in the figure below, in the CPU-Z software interface, you can directly see the "number of cores" and "number of threads", for example, the CPU in the following figure is four cores and eight threads

You tell me what CPU you are, and I'll be able to tell you if it's dual-core or quad-core.

If you don't know what CPU you are, please right-click on "My Computer", select "Properties", and tell me the CPU message displayed, or go to the Internet to check this information yourself.

All i3 CPUs are not dual-core, they have hyper-threading technology, and the system thinks that he is only quad-core, but in fact it is still dual-core.

The i3 is dual-core four-threaded, Intel's hyper-threading technology, two cores, each core can be used as two cores.

Equivalent to quadruple core This answer is correct, the JS of the computer city always says quad core, in fact, it is fooling.
