Ask someone to help you interpret the parameters of CPUZ

Now CPUs support both 32-bit and 64-bit operations, Intel's CPU, if there is EM64T in the instruction set, it means that it supports 64-bit operations, AMD's CPU, if the instruction set ** has x86-64, it means that it supports 64-bit operations, and 32-bit is supported by default.

The instruction set EM64T is Intel's 64-bit CPU technology, so your CPU is 64-bit.

The landlord may also want to ask whether it is suitable to install a 64-bit system, if the landlord's memory is greater than 3G It is recommended to install, otherwise please press the installation of 64-bit, and the graphics card bar friend will answer for you.

CPU-Z Processor Bits:

Open Cup-Z, under the Processor tab, you need to look at the number of bits of the CPU through the instruction set, but in this regard, Intel and AMD are different, although their technology is roughly the same:

1. The following figure shows the example of Intel processor.

2. The AMD processor is shown in the figure below.

Intel's EM64T technology, the official full name of EM64T technology is Extended Memory 64 Tenchnology

The Chinese explanation is to expand the 64bit memory technology. The current 32-bit Pentium 4 CPU is based on the IA-32 instruction set, EM64T is actually based on this instruction set to expand, we named it this method of achieving 64 bits is actually similar to AMD's x86-64 technology, all of which are compatible with 32-bit and 64-bit operations through 64-bit extended instructions. Another difference is that Intel's EM64T technology sets the activation procedure for IA-32 and IA-32E modes, which means that EM64T needs to meet certain conditions before it can be activated.

CPU-Z is an authoritative tool for identifying processor and related system information, which can accurately detect hardware information such as CPU, motherboard, memory, graphics card, and SPD. So how do you check the computer parameters when using CPU-Z? Let's take a look at the specific tutorial on how to use the answer.

1. CPUZ is openedSevenpage, the first page,Processor, this screen will display various information about the processor, such as:Name, Codename, Slot, Stepper, but most of these are not used, and the general information on this page isVoltage and frequencyIt is worth noting that the right click on this interface will open a submenu, which will display all the cpuThe frequency of the core

2. Switch to"Motherboard".tab, you can see which ones are usedInformation such as the model number and chip of the motherboard.

3. InMemorytab, you can see the memoryType, size, frequencyand other information.

spdIt is a memory chip on the memory, which stores the ID card of the memorySPD pageIt's to show this ID card.

5. InGraphics cardtab, the graphics card's will be displayedMake, model, and presentSaveand other information.

Only the frequency of your computer's CPU. The unit is Hz. The higher the frequency, the faster the computer can theoretically process the data.

That is, the frequency of the CPU, in Hz.

CPU frequency is the clock frequency of the CPU, which is simply the frequency at which the CPU operates (the number of synchronization pulses that occur in 1 second).

The frequency of the CPU determines the running speed of the computer, and with the development of the computer, the main frequency has developed from the past MHz to the current GHz (1GHz = 10 3MHz = 10 6khz = 10 9Hz).

In the same series of microprocessors, the higher the frequency, the faster the computer, but for different types of processors, it can only be used as a reference.

The computing speed of the CPU also depends on the performance indicators of all aspects of the CPU pipeline. Since the main frequency does not directly represent the computing speed, in some cases, it is likely that the actual computing speed of the CPU with a higher frequency will be lower.

The clock speed is only one aspect of CPU performance, not the overall performance of the CPU.
