How Do You Know if You Have 32 or 64 Bit Windows 10

There are a lot of ways to count, only when it comes to computers in that location is only binary: 0 and 1. Each ane is a considered a "fleck." That means for ane-fleck computing, you get two possible values; 2-scrap ways four values; so at three bits you double that to eight (2 to the tertiary power, aka 2 cubed).

Keep going exponentially and you eventually become 32-chip (2 to the 32nd ability) worth iv,294,967,296; 64-flake (or two to the 64th power) is worth eighteen,446,744,073,709,551,616 values. That's 18.four quintillion and change.

That's a lot of bits, and the numbers show just how much more than powerful a fleck that supports higher-flake calculating tin can be. Information technology's a lot more than double.

That'southward because every few years, the chips inside the computers (even smartphones) and the software running on those chips make leaps forward in supporting a new number. For case:

• The Intel 8080 chip in the 1970s supported 8-scrap calculating.
• In 1992, Windows iii.1 was the first 16-bit desktop version of Windows.
• AMD shipped the first 64-fleck desktop chip in 2003.
• Apple made Mac Os 10 Snow Leopard entirely 64-flake in 2009.
• The first smartphone with a 64-bit fleck (Apple A7) was the iPhone 5s in 2014.

Information technology's pretty obvious: 64-chip, sometimes styled as x64, is capable of doing more than 32-fleck. You might know 32-bit as x86, a term that originally referred to any Os with the educational activity set up to piece of work on Intel chips like the 8086 through 80486.

These days, yous are most likely already running 64-bit fries with 64-chip operating systems, which in turn run 64-bit apps (for mobile) or programs (on the desktop, to settle on some nomenclature). But not always. Windows 7, 8, 8.1, and 10 all came in 32-fleck or 64-bit versions, for case.

How do you even tell which one yous accept?

Place a 64-Bit OS

If yous are running Windows on a computer less than 10 years old, your chip is almost guaranteed to exist 64-chip, but y'all may have installed a 32-bit version of the Os. It's easy enough to check.

In Windows 10, go to Settings > System > About or type About in the Windows x search box. Under the Device specifications heading, yous'll see it at System type: "64-bit operating organisation, x64-based processor" means you lot're covered.

Mac users don't accept to worry about this, as MacOS has been 64-chip only for a long time. In fact, equally of the latest version (ten.xiv Catalina) 32-scrap applications on a Mac aren't fifty-fifty technically supported, but nosotros accept a guide for running 32-Chip apps in MacOS Catalina. If y'all must.

Why 32-Bit at All?

Why would you install a 32-bit OS on a PC? The big reason is because you have a 32-flake processor, which requires a 32-bit Os.

Having such a CPU today is unlikely. Intel started making 32-scrap processors in the 80386 range manner back in 1985; it was selling 64-chip processors by 2001. If you lot've bought a PC since the Pentium D chip came out in 2005, it'southward unlikely you'd have only a 32-chip instruction set inside.

More probable, you lot have an former system with an operating arrangement yous installed that only came as 32-bit. Subsequent upgrades, if any, may not accept jumped your install up to 64-flake. That may be fine—not all of the earliest 64-bit processors had all the features in place. Yous can decide if your PC is really ready for full 64-fleck by using software similar 64bit Checker. It works on all versions of Windows going dorsum to Windows 95.

Installing a 32-bit OS on a 64-bit-architecture system tin can piece of work, but it's not optimal. A 32-bit Bone, for instance, has more limitations—the standout existence it can only actually use 4GB of RAM. Installing more than RAM on a system with a 32-fleck OS doesn't have much touch on performance. However, upgrade that arrangement with excess RAM to the 64-bit version of Windows, and y'all'll discover a difference.

This should spell it out in the starkest way: the officially supported maximum RAM on Windows ten is two terabytes (or 128GB on Windows x Abode).

The theoretical limit of RAM at 64-scrap: 16 exabytes. That's equal to 1 million terabytes or i billion gigabytes. But we're a long way from having hardware that could ever support that. (Either mode, it makes buying a new laptop with 16GB of RAM seem unimpressive, doesn't it?)

64-bit computing features many other improvements, though in ways that may not exist noticeable to the naked eye. Wider information paths, larger integer sizes, viii-octet memory addresses. Information technology's all stuff for the computer scientists to take advantage of, to make your computing all the more powerful.

Programs in 64-Bits

You may also find that some programs you download for your desktop operating system come in 32- and 64-bit versions. Firefox is a proficient example, where the options are "Windows 32-flake" and "Windows 64-fleck" (also as "Linux" or "Linux 64-bit"—the macOS version is 64-bit only).

Why do that? Because 32-chip OSes are notwithstanding out there for some. Those systems demand 32-bit software—they typically can't even install a 64-bit program, and certainly won't run them. Still, a 64-bit OS can support a 32-scrap program—Windows in particular has congenital in an emulation subsystem for that, called Windows32 on Windows64, or WoW64.

Look in your C: drive former—you lot'll see two Programme Folders: one for 64-bit programs, another called Programme Folders (x86) just for 32-flake applications. You'll be kind of astounded how much 32-bit lawmaking is still out there.

On the Mac, you're less likely to find much 32-scrap-ness, which is why Apple is banning 32-scrap apps under Catalina, or at least trying. Merely you can check your apps. On the Apple tree menu, select Nearly this Mac, click System Report, and highlight all the applications listed under Software. Each will take a "64-bit (Intel)" entry reading Yes or No. Most are going to be Yes. If you have an important program that says No, avert Catalina for at present or read our workarounds.

A Scrap About Mobile 64-Bit

As noted above, Apple'southward A7 chip was the first 64-bit processor to go into a mobile phone (the iPhone 5s). In 2015, Apple mandated that all iOS software had to go 64. As of June 2016, opening a 32-bit app in the latest versions of iOS caused a "non optimized" alarm: "using it may affect overall system functioning."

If you've got an iPhone 5s or higher with iOS x or higher, you can't utilise those older 32-bit apps that haven't had an update. That'due south the "best" thing about Apple'due south closed system—it tin force that to happen.

On Android phones, information technology can be a little trickier to uncover details unless yous're well-versed on what chip is inside. If you're non running Android 5.0 Lollipop or newer, y'all're notwithstanding 32-bit. I app that will tell you lot is AnTuTu Criterion; load it, click the Info button, and expect for the Android line. It'll tell you the Android version and if it's 32- or 64-bit.

For iOS and Android, this isn't near opening upward the OS to using more RAM. In fact, going x64 isn't a guarantee of better performance. Going 64-bit has other benefits—things like fetching even more data per wheel (and faster), better encryption, and overall moving to new 64-bit chips with improved features, similar power efficiency.

Ultimately, the 64-bit revolution is already here. And you don't need to know anything virtually x64 to be part of it.
