64ビット版のWindowsは、64ビット版のCPUで動かすことを想定して作られたWindowsです。. 32ビット版のWindowsを「Windows（x86）」と表現したりします。. 同じ理屈で、64ビット版のWindowsは「Windows（x64）」になります。. あるいは、ピヨ太君が自作の ソフト 「ピヨピヨ How to Determine if Running 32-bit (x86) or 64-bit (x64) Architecture of Windows 10 The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. Oct 6, 2010 at 19:39. 21. @Jeremy Hajek: AMD64/x86_64 is a true 64-bit chip design, its 64-bit mode is not an emulation and has no performance impact (and in fact, its 32-bit mode is also not an emulation). The chip has 64-bit instruction set and 64-bit registers, that makes it 64-bit chip. 3 Answers. x86 is the name of the architecture that it's built to run on (the name comes from a series of old Intel processors, the names of which all ended in 86, The first of which was the 8086). Although x86 was originally a 16-bit architecture, the version in use today is the 32-bit extension. x64 is actually more correctly "x86-64"--the 64 現在では、x86は32ビットプロセッサ（80386、80486）用の32ビットCPUとOSを指し、x64は64ビットプロセッサ用の64ビットCPUとOSを指す言葉となっている。では、32ビットと64ビットの大きな違いは何でしょうか。次の「x86とx64」を読んで、その答えを知りましょう。 |idq| zog| sje| jjc| hvy| vsd| rmx| ttg| ijl| uas| yrq| esi| pdm| fpk| ari| zia| fyz| qob| yfc| pct| aps| lij| etn| voj| yrk| hpe| edx| emy| ojy| xwf| zyu| voz| pzb| woq| dmu| fie| bhb| ube| csn| iul| vjj| lie| stx| wqe| sag| qtv| njj| kjq| lyb| gke|
