10 alternative pc operating systems you can install

10 alternative pc operating systems you can install

No list of alternative PC operating systems could be complete without Linux. Its the alternative PC operating system. Linux comes in many different flavors, known as Linux distributions. Ubuntu and Mint are some of the most popular. If you want to install a non-Windows operating system on your PC and actually use it, you should probably pick Linux.

Linux is a Unix-like operating system, and there are other open-source operating systems like FreeBSD out there. FreeBSD uses a different kernel, but it uses much of the same software youd find on a typical Linux distributions. The experience of using FreeBSD on a desktop PC will be pretty similar.

Chrome OS isnt really a general-purpose PC operating system instead, its designed to be preinstalled on specialized laptops, known as Chromebooks. However, there are ways to install Chrome OS on your own PC.

Valves SteamOS is currently in beta. Technically, Steam OS is just a Linux distribution and includes much of the standard Linux software. However, SteamOS is being positioned as a new PC gaming operating system. The old Linux desktop is there underneath, but the computer boots to a Steam interface designed for living rooms.

In 2015, youll be able to buy PCs that come with SteamOS preinstalled, known as Steam Machines. Valve will support you installing SteamOS on any PC you like its just not anywhere near complete yet.

Android also uses the Linux kernel, but practically everything else on Android is very different from typical Linux distributions. Originally designed for smartphones, you can now get Android laptops and even desktops. Its no surprised that a variety of projects exist to run Android on traditional PCs Intel even develops their own port of Android to PC hardware. Its not an ideal operating system for your PC it still doesnt allow you to use multiple apps at the same time but you could install it if you really wanted to.

Apples Mac OS X is preinstalled on Macs, but Macs are now just another type of PC with the same standard hardware inside. The only thing stopping you from installing Mac OS X on a typical PC is Apples license agreement and the way they limit their software.Mac OS X can run just fine on typical PCs if you can get around these restrictions.

BeOS was a lightweight PC operating system ported to the Intel x86 platform in 1998, but it wasnt able to stand up to Microsofts Windows. Be Inc. eventually sued Microsoft, accusing them of pressuring Hitachi and Compaq to not release BeOS hardware. Microsoft settled out of court, paying $23.5 million to Be Inc. without admitting any guilt. Be Inc. was eventually acquired by Palm Inc.

OS/2 was an operating system originally created by Microsoft and IBM. IBM continued development after Microsoft left it and OS/2 competed with MS-DOS and the original versions of Windows. Microsoft eventually won, but there are still old ATMs, PCs, and other systems using OS/2. IBM once marketed this operating system as OS/2 Warp, so you may know it by that name.

IBM no longer develops OS/2, but a company named Serenity Systems has the rights to continue distributing it. They call their operating system eComStation. Its based on IBMs OS/2 and adds additional applications, drivers, and other enhancements.

ReactOS is a free, open-source reimplementation of the Windows NT architecture. In other words, its an attempt to reimplement Windows as an open-source operating system thats compatible with all Windows applications and drivers. ReactOS shares some code with the Wine project, which allows you to run Windows applications on Linux or Mac OS X. Its not based on Linux it wants to be an open-source operating system built just like Windows NT. (Modern consumer versions of Windows have been built on Windows NT since Windows XP.)

Syllable is an open-source operating system forked from AtheOS, which was originally intended to be an AmigaOS clone. Its a lightweight operating system in the tradition of the Amiga and BeOS, but built using many parts from the GNU project and Linux. Like some of the other smaller operating systems here, it has only a handful of developers.

Unlike many of the other hobbyist operating systems here, SkyOS is proprietary and not open-source. You originally had to pay for access so you could use development versions of SkyOS on your own PC. Development on SkyOS ended in 2009, but the last beta version was made available as a free download in 2013.

So in 2013, the startup turned the inexpensive Raspberry Pi into an award-winning kid-friendly computer by adding a simple picture-book instruction manual and Lego-like blocks of code so kids could teach themselves. They've sold over 100,000 so far.

Now, the company's moving beyond the Raspberry Pi with three new computers. They let kids (or adults) build a camera, LED display, or speaker they can program with the same blocks of code -- each with its own dials, buttons, sensors, and integrated rechargeable battery so you can take them on the go.

Each has its own "Kano Brain" with a 1.2GHz ARM processor on a custom board, instead of a Raspberry Pi. Each Kano creates its own Wi-Fi network so you can log into a web portal to build and tweak your code, and share creations with other Kano users around the world.

What can you do with a programmable camera, screen, or speaker that you couldn't do with a normal one? Klein had a bunch of ideas to start. With some simple code, he turned the ring of LEDs around the camera kit into a countdown timer, and the LEDs into a music visualizer by programming them to light up in response to sound.

Each of the kits comes with an extra sensor, too, like an infrared laser tripwire for the Camera Kit, so you can have it take a picture when someone passes by. The Speaker Kit comes with a gesture sensor, and the screen (Pixel Kit) with a low-tech tilt sensor (you can see the metal ball bearing inside).

Kano's Kickstarter campaign starts today, and you can take your pick of the three kits for $100 (about 77 or AU$130) during the campaign. (As always, there's a chance that Kickstarter projects won't succeed.)

AMD's Ryzen 3000 and Athlon processors (including the unlocked $49 Athlon 3000G) have shaken up the low-cost landscape and made a splash on our CPU Benchmarks Hierarchy, but crushing shortages of chips has gripped the industry, which impacts the low end of the market in a particularly painful way. So even though quad-core models with gaming-capable integrated graphics have an MSRP for a mere $100, and the Athlon lineup now dips below 50 bucks (although it's not always easy to find the 200GE at the moment), supply is short. Intel's response to AMD's challenge has brought Hyper-threading to its low-end Pentium processors and two additional cores to the Core i3 line, which greatly improves performance for its budget chips even though they're still limited in terms of their graphics.

AMD hasn't released its Ryzen 5000 chips for the low-end yet; the series bottoms out at the Ryzen 5 family. We expect that Ryzen 3 models will come in due course, shaking up our low-end rankings. Intel also has its Rocket Lake processors incoming next month, but these chips will use the refreshed Comet Lake architecture for the Core i3 and below chips, so they probably won't have much impact on our rankings.

The 200-series AMD chips are surprisingly capable at gaming even without a dedicated card.For more details about how the 200GE stacks up against Intel's comparable budget chip, see our feature AMD Athlon 200GE vs. Intel Pentium Gold G5400: Cheap CPU Showdown.

For those looking for something with a bit more gaming prowess without having to resort to a dedicated graphics card, AMD's Ryzen 5 3400G is tough to beat. While the Ryzen 4000 APUs are faster, they're not readily available and cost a lot more. The 3400G is a solid option but doesn't offer a big performance boost over previous-generation chips like the Ryzen 5 2400G.

If your budget is a bit more flexible and you're looking to pair your processor with dedicated graphics for gaming, AMD's Ryzen 3 3300X is great if you can find it at retail around the MSRP of $120, and Intel's new Core i5-10600KF is impressive at about twice that amount. But like so many other PC components, both of these processors are hard to find in stock at reasonable prices. Hopefully availability will improve over time, but it probably won't happen until later in 2021, at which time we'll have new processors.

For even more information, check out our CPU Buyers Guide, where we discuss how much you should spend for what youre looking to do, and when cores matter more than high clock speeds. If you can expand your budget and buy a mainstream or high-end processor, check out our lists ofBest CPUs for Gamingand Best CPUs for Workstations.Below, you'll see our favorite budget picks.

The Ryzen 3 3300X unlocks a new level of performance for budget gamers with four cores and eight threads that can push low- to mid-range graphics cards to their fullest. This new processor wields the Zen 2 architecture paired with the 7nm process to push performance to new heights while enabling new features for low-end processors, like access to the speedy PCIe 4.0 interface. The 3300X's four cores tick at a 3.8 GHz clock rate and boost to 4.3 GHz, providing snappy performance in lightly threaded applications, like games.

AMD includes a bundled Wraith Spire cooler with the processor. Still, you might consider budgeting in a better low-end cooler to unlock the full performance, particularly if you are overclocking. Speaking of which, the Ryzen 3 3300X can overclock to the highest all-core frequencies we've seen with a Ryzen 3000-series processor, making it a great chip for enthusiasts. Unlike AMD's other current-gen Ryzen 3 processors, you'll need to pair this processor with a discrete GPU, but the low price point leaves extra room in the budget for a more capable graphics card.

You can stick with the value theme and drop this capable chip into existing X470 of B450 motherboards, but you'll lose access to the PCIe 4.0 interface in exchange for a lower price point. Better yet, AMD will have its new B550 motherboards on offer in June 2020. These new motherboards support the PCIe 4.0 interface but provide lower entry-level pricing that's a better fit for this class of processor.

When money is tight, being able to game without a graphics card can lead to serious savings. And with RAM prices continuing to soar, those working with small budgets need to tighten the strings anywhere they can.

That makes the four-core, four-thread Ryzen 3 2200G particularly appealing for budget gaming builders and upgraders. The $99 chip delivers solid 720p performance thanks to its Vega on-chip graphics, decent CPU muscle for mainstream tasks, and can be dropped into an existing inexpensive 300-series motherboard (after a requisite BIOS update), to form the basis of a surprisingly capable low-cost PC. Its also unlocked, so with proper cooling you can tune the graphics or the CPU to best suit your needs.

AMD's Athlon 240GE serves as the flagship of the company's budget lineup, but it still packs a convincing punch for low-end gaming systems. The integrated Radeon Vega 3 graphics facilitate playable frame rates at lower resolutions and quality settings, but the 3.5 GHz base clock is the only differentiating feature between the Athlon 240GE and its counterparts. Due to the unofficial support for overclocking, that means you can tune the Athlon 200GE to the same top performance as the more expensive chips, but at a $20 price savings.

If overclocking isn't in your plans, the Athlon 240GE is the best budget chip in its price band. Intel's competing Pentium lineup lacks the graphical horsepower to be serious contenders for the extreme low-end of the budget gaming market, but they are attractive if gaming isn't your primary goal. That is, of course, if you can find them.

AMDs sub-$60 Zen-based Athlon is a good all-around value, thanks to its four computing threads and Vega 3 graphics that are capable of light gaming at lower resolutions and settings. Lightly threaded performance isnt great, but when youre spending this little on a CPU, you should expect compromises somewhere. And while it isnt officially supported by AMD, if you have a compatible motherboard, this chip can be overclocked to eke out some extra CPU performance.

If your build budget can swing it, the $100 Ryzen 3 2200G is a much better chip with more cores and beefier graphics. But if you can only spend $60 or less on your CPU and you arent adding a dedicated graphics card, the Athlon 200GE is tough to beat. Intels competing Pentiums, the Gold G5400 and G4560, deliver better CPU performance. But they have higher MSRPs, and production shortages have made them hard to find unless youre willing to spend close to $100 or more, making them incomparable in terms of budget CPUs.

You won't find many game titles that will play well at the popular 1920X1080 resolution on the sub-$80 chips, but there are a few.As we can see, AMD's $100 Ryzen 3 2200G is the undisputed king of the hill for 1080p gaming on integrated graphics, but the Athlon chips also push out playable frame rates in a few titles (if you're willing to tolerate lower graphics quality settings).

Switching over to 1280x720 finds the Athlon processors providing up to 50 FPS at stock settings and experiencing a decent performance boost from overclocking. Remember, all of the Athlon chips will benefit equally from overclocking, meaning the Athlon 200GE and 220GE will achieve the same level of performance as the overclocked Athlon 240GE. That's an amazing value for these low-cost chips. It should go without saying, but the Ryzen 3 2200G's Radeon Vega 8 graphics engine blows through the 1280x720 tests with ease.

Intel's Pentium lineup, and even the Core i3-8100 for that matter, struggle tremendously under the weight of these titles. Gaming at 1920x1080 is a painful experience: You won't find many games that are playable on Pentium processors at that resolution. Switching over to the 1280x720 resolution brings the Core i3-8100 and Pentium G5600 into acceptable territory, but those chips still can't match the Athlon's performance, not to mention the crazy good savings. Intel's Pentium G5400 is particularly disappointing, though, due to its pared-down UHD Graphics 610 engine. We wouldn't recommend this processor for gaming on integrated graphics.

But it's hard to recommend Pentium processors at all right now. Intel is struggling with a shortage of 14nm production capacity, so these chips are extremely hard to find, and when you do find them, they are subject to severe price gouging.

We focus primarily on integrated graphics gaming performance for ultra-budget chips, but these processors are also a great pairing with low-end discrete graphics cards. Below, we've tested the chips paired with an Nvidia GeForce GTX 2080 at the 1920x1080 resolution to remove any GPU limitations from our tests below. We tested with an Nvidia GeForce 1080 FE graphics card to remove graphics-imposed bottlenecks, but the difference between the processors will shrink with the cheaper graphics cards that are commonly found in budget builds. Provided the performance deltas are small, you can select less expensive models and enjoy nearly the same gaming experience with graphics cards on the lower-end of the GPU benchmarks hierarchy.

Intels Coffee Lake Pentium models come with slight frequency improvements, a 3W increase in the TDP rating, and 4MB of L3 cache. These slight adjustments deliver a surprising boost to performance compared to the previous-gen Kaby Lake models. The Coffee Lake Pentium Gold G5600 even beats out the Kaby Lake Core i3-7100 in most of our gaming benchmarks, highlighting the impressive performance gains Intel made within a single generation.

The G5600 grapples with the Ryzen 3 2200G. The Ryzen 3 2200G is relatively simple to overclock with single-click options in the BIOS, and the bundled cooler provides enough headroom for all but the most extreme overclocking efforts. At stock settings, the 2200G trails the Intel Pentium Gold 5600, but the advantage of AMDs unlocked multipliers is clear: At $99, the tuned Ryzen 3 2200Gs performance nearly matches the $117 Core i3-8100.

The Ryzen 3 2200G also comes with powerful integrated graphics that provide surprisingly strong gaming performance at lower resolutions and quality settings. Thats a feat the Core i3-8100 simply cannot match. If youre seeking the absolute best gaming performance (when paired with a dedicated card) regardless of price, the Core i3-8100 fits the bill. If you want the most bang for your buck or plan on gaming on integrated graphics, the Ryzen 3 2200G is the clear value winner.

The Core i3-8100s solid mixture of frequency and IPC throughput delivered to our expectations. The agile processor took the lead in several of our lightly-threaded applications, like the Adobe Cloud suite, but it is also surprisingly powerful in threaded workloads. The Intel Core i3-8100 also offers superior performance in applications that use AVX instructions, like HandBrake, which is a great addition to its impressively well-balanced repertoire. Much like we observed in our gaming tests, the Core i3-8100 offers the best overall performance.

The Ryzen 3 2200G continues to impress with its lower price point and competitive performance, not to mention the integrated Vega graphics, making it the obvious choice for budget builders who are willing to spend a little extra time on tuning.

The Pentium lineup excels in most applications, but the Athlon processors also offer an impressive level of performance. It's also noteworthy that Intel's Pentium processors don't accelerate AVX instructions, a staple in many types of rendering applications, while the Athlon processors fully support the densely-packed instructions. Intel's chips lead in lightly-threaded applications, like web browsers, but the competing AMD chips also offer more than suitable performance in those workloads.
