What do you mean by x64 and x86 of WIN7? WIN7 X86 stands for WIN7 32-bit operating system.

WIN7 X64 stands for WIN7 64-bit operating system.

General CPU support, more than 4G memory, it is recommended to install 64-bit WIN7 system.

What do X86 and X64 in Win7 _ 7600 _ x86-x64 _ Ultimate _ CN _ 2in1_ dvd.iso mean? X86 is a 32-bit system with X86 framework, and X64 is a 64-bit system. Your CPU can be installed, but it will be stuck. If you insist on installing, X86 version is suitable for you.

What do win7 X64 and X86 mean? X64 indicates that the CPU is a 64-bit version. X86 means that the CPU is a 32-bit version. If your CPU is 64-bit. You can install 64-bit or 32-bit, and vice versa.

What does x86 x64 mean? X86 or 80x86 is a general term for microprocessor architecture first developed and manufactured by Intel. The names of the early processors in this series are all expressed by numbers and end with "86", including Intel 8086, 80 186, 80286, 80386 and 80486, so its architecture is called "x86". Because numbers cannot be used as registered trademarks, both Intel and its competitors use registrable names in the new generation of processors, such as Pentium. At present, Intel calls x86-32 IA-32, which means "Intel architecture, 32-bit".

In computer architecture, 64-bit integers, memory addresses or other data units mean that they can be as wide as 64 bits (8 bytes). In addition, the architecture of 64-bit CPU and ALU is based on the size of registers, memory buses or data buses. Since1960s, 64-bit CPU has existed in supercomputers. As early as1990s, there were workstations and servers based on RISC. In 2003, it was introduced into the mainstream of personal computer field in the form of x86-64 and 64-bit PowerPC processor architecture (previously 32-bit).

What do x86 and X64 mean? X86 refers to a 32-bit system.

X64 refers to a 64-bit system.

What do x64 and x86 mean? X64 stands for 64 bits (generally referring to the number of bits in a computer system).

X86 refers to 32 bits.

Hope to adopt

X86 is the standard abbreviation for Intel processor-based systems. X is processor independent. It is a simple wildcard definition for all *86 systems. It is the serial number of Intel General Computer Series, and also identifies the instruction set of General Computer. Because the CPU numbers of intel in the early days were all 8086 and 80286, and the whole series of CPUs were instruction compatible, X86 was used to identify the instruction set used. Today, Pentium, P2, P4 and Celeron series all support X86.

64-bit computing has two main advantages: it can perform a wider range of integer operations; Can support more memory. We can't simply think that the performance of 64-bit processor is twice that of 32-bit processor because of the change of numbers. In fact, under 32-bit applications, the performance of 32-bit processors will be stronger. Even a 64-bit processor is effective in the current 32-bit application. So we should realize the advantages of 64-bit processors, but we should not be superstitious about 64-bit processors.

The only 64-bit operating system that is really suitable for personal use is Windows XP X64, which is only a transitional 64-bit operating system and will be eliminated after the release of Windows Vista, and Windows XP X64 itself is not perfect and easy to use. An obvious example is that the drivers of various hardware devices are very imperfect, and there is basically no 64-bit application software at present. Indeed, hardware vendors and software vendors are reluctant to write drivers and application software for a transitional operating system. So if you want to realize real 64-bit computing, I'm afraid it will take some time for Windows Vista to become popular.

AMD64 bit technology

The bit technology of AMD64 is based on the original 32-bit X86 instruction set, and the X86-64 extended 64-bit X86 instruction set is added, which makes this chip compatible with the original 32-bit X86 software in hardware, and also supports X86-64 extended 64-bit computing, making this chip a real 64-bit X86 chip. This is a true 64-bit standard, and X86-64 has 64-bit addressing capability.

Several sets of CPU registers added to X86-64 will provide faster execution efficiency. Register is the place where CPU creates and stores CPU operation results and other operation results. The standard 32-bit x86 architecture includes eight general-purpose registers (GPR). AMD added eight groups (R8-R9) to X86-64, and the number of registers increased to 16. The default bit of X86-64 register is 64 bits. Eight groups of 128-bit XMM registers (also called SSE registers, XMM8-XMM 15) are added, which will provide more space for SIMD operation. These 128-bit registers will provide 128-bit double precision processing for 3D modeling in vector and scalar calculation modes. By providing more registers, CPU produced according to X86-64 standard can process data more effectively and transmit more information in one clock cycle.

At present, AMD's CPU supporting 64-bit technology includes Athlon 64 series, Athlon FX series and Snapdragon series. Intel's CPU supporting 64-bit technology includes Xeon series with Nokona kernel, Pentium 4 6 series with Prescott 2M kernel and P4 EE series with Prescott 2M kernel.

What do win2003 x64 and x86 mean? X86 is a 32-bit system and x64 is a 64-bit system.

What do win 10 X64 and x86 mean? X64 indicates that the system is a 64-bit architecture and can execute 64-bit and 32-bit programs.

X86 means that the system has a 32-bit architecture and can only execute 32-bit programs.
