The so-called 32-bit processor that can only handle 32, which is 4 bytes of data, and a 64-bit processor can handle 64, ie 8 bytes of data. If we total length of 128 bits, respectively, in accordance with Directive 16, 32, 64 units of the Editor: older 16-bit processors such as Intel 80286 CPU requires 8 instructions, 32-bit processor requires four instructions, And as long as two 64-bit processor instructions, obviously, in the case of the same operating frequency, 64-bit processor, processing speed than the 16, 32 faster.
And in addition to computing capabilities, with 32 processors, 64-bit processor windows 7 ultimate key 32 bit is also reflected in the memory of the control system. The address is the specific integer, and a 64-bit processor ALU (Arithmetic logic unit) and registers can handle larger integer, which is the larger address. Traditional 32-bit processor address space up to 4GB, so many need large memory data processing program at this time will become stretched, forming a bottleneck in operating efficiency. While the 64-bit processor can theoretically reach 18 million TB, 1TB equals 1024GB, 1GB equals 1024MB, so the 64-bit processor can solve 32 computing system bottlenecks encountered, fast first-person For those requiring multi-processor scalability, larger addressable memory, video / audio / three-dimensional processing or high accuracy applications, computing, AMD 64 processor provides exceptional performance.
Here's 64-bit technology is relative to the 32 terms, this refers to the number of bits CPU GPRs (General-Purpose Registers, general purpose registers) data width is 64-bit, 64-bit instruction set that is running a 64-bit instruction, means that the processor can run 64bit data once. 64bit processor not now have, and in the high-end RISC (Reduced Instruction Set Computing, reduced instruction set computer) very early 64bit processor, such as SUN embarrassing UltraSparc Ⅲ, IBM embarrassing POWER5, HP embarrassing Alpha, etc. . 64bit computing has two main advantages: You can carry out a wider range of integer arithmetic; can support more memory. Not because of changes in the figures, but simply that the performance of the processor is 32bit 64bit processor performance twice. In fact in thewindows 7 professional keys, 32bit processor performance even stronger, even 64bit processor, but also in the present case under the stronger performance 32bit applications. So to recognize 64bit processors, but not superstitious 64bit.
To achieve a real sense of 64-bit computing, the light has a 64-bit processor is not enough, you have to have a windows 7 pro activation key and 64 job applications, three are indispensable, the lack of any kind of Elements are unable to achieve 64-bit computing. Currently, 64 processors, Intel and AMD processor vendors have released a number of series of 64 kinds of specifications processor; while in the operating system and application software, the current situation is not optimistic. Because really suitable for the personal use of 64-bit operating system is now the only Windows XP X64, and Windows XP X64 itself is just a transitional 64-bit operating system, after the release of Windows Vista will be eliminated, and Windows XP X64 itself not perfect, ease of use is not high, an obvious example is the various hardware device driver is not perfect, and now 64-bit application software is also basically no, indeed hardware manufacturers and software vendors do not want to go for a transitional nature of the operating system to write drivers and application software. So in order to achieve true 64-bit computing, probably have to wait until some time after Windows Vista universal job.
