The CPU is the most complex, most expensive SOC (chip) on the phone, which is also the location of the brain in the cell phone, and is the decisive hardware for the performance of the mobile phone. The development of smartphones to today, the major mobile phone CPU manufacturers from the spring and autumn warring States gradually to the current four-country separation of the Times (Qualcomm, MTK, Samsung, a
Physical CPU: The physical CPU is relative to the virtual CPU concept, refers to the actual existence of the processor, is that we can see, the touch of the CPU, is inserted in the motherboard above.Physical Core: The number of physical cores that are included in the CPU, su
Among the CPUs currently produced by Intel, Pentium 4 and celon are PC oriented, while Xeon, XeonMP, and Itanium are for workstations and servers. Among them, Itanium is a 64-bit CPU that is completely different from other CPUs. It is not designed for use in existing Windows applications. Although other processors differ in the highest operating frequency, FSB (Front-End bus frequency), and cache capacity, the internal design is basically the same, wh
IPC (Instruction per clock):Number of commands executed by the CPU per clock cycle In fact, the frequency and IPC really affect the CPU performance. Accurate CPU performance judgment criteria should be:CPU performance = IPC (number of commands executed by the CPU per clock cycle) x frequency (MHz clock speed)This form

the difference between CPU bulk and boxed From the technical point of view, the bulk and boxed CPU is not the essence of the difference, at least in terms of quality and performance does not exist problems, more impossible to have a fake CPU (no manufacturers can counterfeit such high-tech products), of course, do not rule out profiteers after grinding to low fr
The most intuitive benefit of binding processes/threads to CPUs is to increase the hit rate of the CPU cache, thereby reducing memory access loss and increasing the speed of the program. I think that under the NUMA architecture, this operation has a significant impact on the speed of the system, and in the SMP architecture the promotion may be relatively small. This is mainly because both the cache, bus, the allocation of these resources are different

From the software point of view of the CPU, it seems that the CPU is a series of instruction symbols. Therefore, we design a CPU, first of all to consider which instructions should be designed. The instruction system of the computer needs to be planned according to the requirement of the task, there will be arithmetic operation instruction, logic operation instru
High CPU usage is a frequent problem for netizens, CPU usage is actually the CPU resources that you run the program, which means that your machine runs a lot of programs at this time. Long-term use will make the CPU for a long time in the hot state will affect the impact of the CPU

Do you want to know the performance of your CPU?Do you think the testing software is too troublesome?Do you think it would be great to have free testing software? Now, you can download my own test_cpu program to test your CPU performance ~Simply run the test_cpu.exe program in double-click mode. Wait for 30 seconds to 2 minutes (depending on the performance of the machine) and you will see the result ~ This

Today, a problem arises: what is a 32-bit CPU, a 32-bit OS, and a 32-bit program? Why can 32-bit CPU only support 4 GB memory? This problem occurs. Today, I ran SSIS and found that the memory was not enough. I checked the memory and found that 4 GB memory only showed more than 3 GB memory. I want to add memory. But I have heard that 32-bit computers can only support 4 GB memory at most. Why? I don't know.
