Software compatibility is hitting or miss
The Raspberry Pi line of unmarried-board computers has been enormously popular, cheers to its super affordable price, meaty size and maker-friendly design. The latest version, the Raspberry Pi 4 Model B ($55 equally tested), is the most powerful yet, getting a major increment in processing power, enhanced video output and peripheral connectivity, while maintaining the same low toll and tiny size offered on past models.
The new Pi iv gets exciting features, like USB 3.0 ports, ability over USB Type-C and Ethernet, and video output that volition handle 2 4K monitors at a time. Plus, you still go all the unique connectivity and expansion of the Pi's GPIO pins and compatibility with past add together-ons and accessories. But all those changes do come with some new inconveniences. Because of the tweaks made to the Pi 4, the software used on older models is not direct uniform, and the updated port selection means that older case designs won't work with the new model.
One affair remains true about the latest Raspberry Pi, all the same. Information technology's notwithstanding the best mini PC for tinkering, and with the improvements to the Pi iv, it's proven itself to be one of the best computers menstruum if you're looking to get a lot done with a trivial.
Editor's Note: (Mar 26, 2021) Since our initial review in 2019 the Raspberry Pi iv Model B has continued to improve, with issues fixes and even a new version built inside a keyboard, the Raspberry Pi 400 . Our initial rating and recommendation remain unchanged from when it originally published in October of 2019.
Raspberry Pi 4 Model B cost and configurations
The Raspberry Pi iv Model B is the first of the fourth generation of Raspberry Pi computers. The latest model brings with it a more powerful Broadcom BCM2711B0 quad-core ARM processor and the 4K-capable Broadcom VideoCore VI video processor, along with the move to faster USB 3.0 ports and USB Type-C for power.
It'due south available in iii variations, which differ but in the amount of LPDDR4 SDRAM installed on the board. The base model comes with 1GB of retentivity and sells for $35, maintaining the same low toll the Pi has ever had. A 2GB model doubles the memory for a price of $45, while the top model – and the model we reviewed – bumps the RAM to 4GB, for $55.
Merely the Raspberry Pi family is much larger than the Pi 4. Previous generations of the Pi are also available, including the Raspberry Pi 3 B+ we reviewed in 2018 and the Raspberry Pi ii Model B nosotros looked at in 2016. For applications where you may not demand the extra processing power of the Pi 4, these are still superb options, delivering cheap unmarried-board systems that can exist programmed, connected to the web and used for everything from dwelling house automation to sophisticated robotics.
It's also worth looking at the naming conventions used to distinguish the various versions of the Raspberry Pi. The number – Pi 4, Pi 3, Pi ii, etc. – denotes which generation it is and volition include improvements to both processing power and the layout of the board. The model designations (A, B and B+) indicate the specific design. The Model B is the standard, general-use single-board organisation, while the Model B+ boasts an iterative improvement in capabilities (the B+ models usually come between full generation changes). The Model A has a more compact design that ditches almost of the bulky Ethernet and full-size USB ports constitute on the Model B and has a smaller footprint, but information technology still offers the same processor and capabilities.
And for something even smaller and less expensive, at that place'due south the Pi Cipher ($ten.00) and the Pi Zero Westward ($15.00). At roughly a third the size of the standard Raspberry Pi, it offers some (but not all) of the same functionality and is available with and without wireless connectivity – the "Westward" in Pi Zero W indicates the model comes with Wi-Fi and Bluetooth.
Raspberry Pi four Model B design
Famous in function for its small size, the Raspberry Pi line of inexpensive computers is famously no bigger than a deck of cards, and the Raspberry Pi 4 Model B measures simply 3.4 10 2.2 x 0.4 inches. That puts it in the aforementioned iii.4 ten 2.2 footprint offered on older models of the Raspberry Pi, simply it's actually slimmer past almost a quarter inch. And it's virtually identical in weight, weighing in at 46 grams (1.62 ounces) – just a gram heavier than previous generations, similar the Raspberry Pi three B+ (45 grams, or 1.58 ounces).
The bodily design of the Raspberry Pi is pretty unique, both in terms of what it has to offer as well as what it doesn't. The small computer comes as a bare excursion board, without any sort of housing, or any of the niceties that you might get with a traditional mini PC, such as a cooling fan or even a power button. The Pi 4 is as bare bones equally it gets.
The list of ports on the Pi 4 as well serves as a rundown of the few concrete features offered on the pocket-size computer, with four USB ports (two USB 3.0 and ii USB two.0), a pair of micro HDMI ii.0 ports and a USB Blazon-C power jack. A 3.five-millimeter jack serves as an analog audio/video-out port; and Gigabit Ethernet – with full throughput, which wasn't offered on past models of the Pi – gives you wired networking and fifty-fifty ability, thank you to Power over Ethernet support. For wireless networking, the Pi boasts both 802.11ac Wi-Fi and Bluetooth five.0.
But in add-on to these familiar ports and connections, the Pi 4 too delivers enormous flexibility. Less common ports include both Photographic camera Serial Interface (CSI), Display Serial Interface (DSI) and a microSD bill of fare slot that lets y'all add storage to the Pi, which comes with no onboard storage of its own.
But the crowning feature of the Pi, in whatever iteration, is the 40-pivot GPIO header. This bristling row of input/output pins provides direct access for connecting external devices. For the DIY tech enthusiast or maker, the Pi 4 is the best version withal of the fan favorite.
Raspberry Pi four Model B accessories
In addition to the Pi 4, we besides picked up some accessories. Some were merely overnice to have, like a example, while others are essential for using the Pi 4 in well-nigh situations.
First, we acquired a SanDisk Ultra 32GB memory card. While many brands and capacities of microSD card will work, you volition demand something, since the card is used for onboard storage and is used for installing the Pi 4'due south operating system.
For power, nosotros got the Raspberry Pi iv official 15-watt ability supply. This ability cable sells for $9.99 and connects over USB Type-C, merely different many tertiary-party USB-C chargers you might exist tempted to try using, such every bit a spare phone charger, this 1 is guaranteed to provide enough power to permit yous fully utilise the Pi 4.
And with the Pi 4 switching to micro HDMI connectors for video output, we too picked upwards a micro-to-standard HDMI cable ($8.99). While this volition work with any HDMI-connected monitor or display (including TVs), the cable too supports the 4K video output offered by the new Pi four. While these specific cables aren't the only selection, the connections used on the Pi iv practise mean that you lot'll demand some sort of adapter if you want to use any HDMI cables that yous already ain.
Other desktop basics, such as a wired mouse, wired keyboard and HDMI-connected monitor are also needed to use the RasPi iv equally a desktop. Nosotros had these things on paw already, just even older used models volition piece of work just fine.

Though it's not as essential for utilise as a ability cable or video connection, we also decided to dress up the Pi four in a instance. For this nosotros used the Pimoroni Pibow 4 Ninja, a user-assembled case made upwards of five layers of custom-cut acrylic. The case is like shooting fish in a barrel to put together, looks swell and has handy laser-etched labels for ports. It likewise has a cutout for adding a heat sink or cooling fan, and it leaves all 40 GPIO pins and other ports accessible for all of your tinkering needs.
Raspberry Pi 4 Model B setup
When you kickoff pull the Raspberry Pi four out of the box, it's nothing more than a excursion board, with plenty of potential, simply none of the ready-to-go capability of a regular PC or laptop. The operating system doesn't come preinstalled – you lot'll take to do that yourself – and any peripherals, like a keyboard, mouse or monitor, will need to be acquired separately.
But even with your peripherals in place, yous'll still need to install the software yourself. To start, you'll need to go your microSD carte du jour and download Raspbian Buster, the operating system adult by the Raspberry Pi Foundation specifically for the Pi 4 (though it volition besides work with past models). Equally the latest version of the Raspberry Pi-themed Linux variant, Raspbian Buster is updated to work with the new Pi 4, supporting the board's updated capabilities and features.
You can download Raspbian directly from the Raspberry Pi Foundation. Download the official image of the Buster operating system and re-create information technology over to your microSD card. (Here are instructions, if needed.)
One time the Raspbian Buster image is on the microSD carte du jour, you can insert it into the menu slot on the Pi 4 and (if everything was installed correctly) power upward the Pi, which will automatically boot into the freshly installed OS.

While these instructions will get y'all up and running, Raspbian Buster isn't the only option available for running your Raspberry Pi. Several Linux-based operating systems are freely available for the RasPi, though information technology may not exist as like shooting fish in a barrel to determine the compatibility of these systems with the Pi 4.
Finally, the popular game emulator RetroPie still doesn't have a Pi 4-uniform version. Since the development and maintenance of RetroPie is a volunteer effort, the filibuster is understandable. There are a couple of unofficial builds that may or may not work on the Pi 4, but an official release volition exist out eventually. (Nosotros'll update this portion of the review once it'south out.)
Raspberry Pi 4 Model B software
Using Raspbian Buster on the Pi four gives you a standard desktop environment, admitting a bones, Linux-based one. Included in the initial installation parcel is a suite of programs that gives you basic web browsing and productivity tools, as well as a collection of educational apps that teach coding and provide tools for adapting the Pi to your own custom projects.
This includes handy productivity tools similar LibreOffice and Chromium, which give you open up-source alternatives to the Microsoft Part suite – including a word processor, spreadsheet program, presentations, drawing, database manager and an equation editor for math and science – and Google's Chrome web browser.

Raspbian as well comes loaded with software for education, giving you gratuitous tools for learning programming languages like Python, Scratch and Java. There are tools for making and playing games in Python, another called Sonic Pi that lets you make music, and there's even a version of Minecraft.
Raspberry Pi 4 Model B functioning
The Pi iv is outfitted with a 1.v-GHz, quad-cadre Broadcom BCM2711B0 (Cortex A-72) processor and comes with up to 4GB of LPDDR4 SDRAM in the top configuration – the model we reviewed.
Firing up the Pi four, I was struck by 2 thoughts. First, I was amazed to encounter the Pi iv back up 4K output, at any frame rate. Earlier Pi models are mostly limited to 1080p, so the movement to 4K is a major jump.
Second, I was struck past how shine and responsive the Pi four was, especially compared with the Pi 3 B+ we reviewed last year. Equally I opened documents and test files, everything just worked, and the laggy performance I accepted as the inevitable reality of an cheap single-lath computer like the Pi three B+ by and large disappeared on the Pi 4. This continued as I browsed online with multiple tabs open up, and I was able to scan with eight to 10 tabs open without any noticeable lag.
I was amazed to run into the Pi 4 support 4K output, at whatever frame rate.
These first impressions were borne out in testing, as the Pi 4 put upwardly results that were substantially better than the model we reviewed last year. While it'southward nonetheless no speed demon compared with other mini PCs, it's definitely the first fourth dimension I've used the Pi and considered using it equally a desktop beyond my initial testing. That this level of performance is bachelor on such a tiny, inexpensive device is seriously impressive.
Everything is faster, starting with kicking times. The Pi four went from a cold start to a usable desktop in just 23 seconds. That's a huge comeback over the older Pi three B+, which booted in 36 seconds; the before Pi ii Model B was even slower, at 45 seconds.
While most of the tests we use on Windows-based mini PCs aren't available on the Linux-based Pi, nosotros were able to compare a number of web-based performance benchmarks.
For full general functioning, nosotros use the JetStream 1.one browser operation test. In this criterion, the Pi 4 scored 42.65 points. Past comparison, the Pi iii B+ scored but 16.vii points in the same examination. That'southward a huge comeback for single-board systems. However, comparison this with more than mainstream systems, like the Azulle Access3 (our favorite Windows stick PC) or the Acer Chromebox CXI3 puts this improvement into context. The Azulle Access3, which boasts an Intel Gemini Lake N4100 processor, scored 101.21 points in the aforementioned test. The Acer Chromebox did even better, notching a score of 168.22 points, cheers to its Intel Core i5 processor.
Graphics performance was similarly improved, only but impressive in a relative sense. Using WebGL Aquarium – a WebGL demo that lets you select gear up numbers of digital fish – the Pi 4 managed to render 50 fish at 3 frames per second (fps). Compared with the Pi 3 B+, which struggled with a single fish, that'south a huge improvement. But compared with the Acer Chromebox CXI3, which handled as many as 10,000 fish at 28 fps, the Pi 4'due south graphics back up is all the same pretty paltry.
However, loading upwardly websites on the Pi 4's Chromium browser wasn't much quicker than it'southward been on other Raspberry Pi models we've seen before. Loading up the Tom's Guide homepage took a quick 2 seconds. The older Pi 3 B+ did the aforementioned in 11 seconds.
YouTube, on the other paw, opened in 11.7 seconds, which was actually a slight drop from both the Pi 3 B+ (x seconds) and even the Pi 2 B (also 10 seconds).
Oddly enough, opening a lightweight site like Stack Exchange, which is mostly text, wasn't much faster; it took iii seconds – merely a 2d faster than the Pi 3 B+ (4 seconds) — which was, in turn, only slightly faster than the Pi two B (5 seconds).

Nevertheless, unlike past versions of the Pi, the newer Pi four was able to actually run more than i or two tabs at once. I was even able to work in a Google Md to work on the first draft of this review while likewise researching specifications in another window and watching a related YouTube tutorial in a third. That level of (absolutely basic) multitasking wasn't really possible on older models.
One other event worth noting about the Pi 4 is that information technology runs hot — much hotter than its predecessor, the Raspberry Pi three B+. While the Pi iii B+ would get warm when under load (up to 142 degrees Fahrenheit), the Pi 4 gets much hotter — upward to 168 degrees Fahrenheit in our testing. That heat makes it imperative that you outfit your Pi with a example, so every bit to avert burned fingers or even adventitious fires. But it likewise will have an impact on operation, since the system will throttle performance when it runs too hot.
And for optimal performance, y'all would practise well to outfit your own Pi 4 with heat sinks for the CPU and GPU, or perhaps a fan (available on many Pi four cases), or both.
Raspberry Pi 4 Model B projects, expansions and kits
Between its small size, superlow toll and ultraflexible form factor, the Pi iv is the virtually powerful version of the all-time tinkering PC on the market. But what tin can you actually exercise with it?
As a member of the Raspberry Pi family, the Pi 4 has an ecosystem of accessories available for it, also every bit a rich community of enthusiasts and makers who have used the Pi for all sorts of projects and are oft willing to offer assistance and respond questions through the many Pi-centric forums and communities online.

That ecosystem includes all sorts of add together-ons for the Pi that connect through the many ports and GPIO pins. Called hats, bonnets and shields, depending upon the specific design and connectivity of the add-on, these expansions make the Pi four (and other models of the Pi) immensely more flexible than your boilerplate PC. Well-nigh of the hats that have worked with previous Raspberry Pi models will still work on the Pi 4, since it uses a nearly identical GPIO pin layout.
Between its minor size, superlow price and ultraflexible form gene, the Pi 4 is the nearly powerful version of the all-time tinkering PC on the market.
These add together-ons range from the elementary to the extremely technical. Y'all can get microphone extension boards, perfect for building your own Amazon Repeat or Google Home. You can add display boards, for making the Pi 4 a handheld computing device – options include multicolored eastward-ink displays, touch screens and more. Motor boards and servo hats are not bad for building remote-control vehicles and robots, speaker bonnets let yous curl your ain streaming music player, and yous can fifty-fifty get a pair of small displays that are made to permit you add blithe eyes to a costume.
And, if you want something that'due south a picayune less intense, but still lets y'all scratch that itch for DIY tech, there are plenty of kits that let you lot get together and experiment, while still holding your hand every bit needed. In that location are basic kits for getting started with the Pi 4, which bundle the Pi 4 with accessories like cables, a case and even a preloaded microSD card. By versions of the Pi accept besides had gaming kits offered, similar a DIY retro console, complete with game controllers, or a build-it-yourself arcade-fashion fightstick kit, to assist you get the real retro gaming feel at home. There aren't many gaming kits out for the Pi 4 just yet, merely that will likely modify once gaming back up improves for the newest fellow member of the RasPi family.
Raspberry Pi four Model B: Verdict
The Raspberry Pi concept has already proven itself a winner, with millions of the single-board computers sold and used in everything from gaming to dwelling automation and robots. But the latest release, the Raspberry Pi 4 Model B, takes the already astonishing Pi concept to new heights, with processing ability that lets you use the inexpensive fiddling reckoner equally a basic desktop, and features like 4K video output that were unthinkable only a year or 2 back.
The Pi 4 isn't perfect. Information technology runs hot and still has limitations that even the most bones stick PC won't be slowed past. Fifty-fifty some of the software that'south readily available for other Pi systems isn't fully baked for the Pi 4, like RetroPie. All of this is on top of the fact that the Raspberry Pi platform asks a lot of its users, and it has a pretty steep learning curve. If user-friendly capability is what you desire, you may be ameliorate served by something similar the Azulle Access3, which gives you a total Windows PC for a couple hundred bucks.
But if yous've ever wanted to make your ain smart mirror (or weather station, or internet radio, or game arcade cabinet, or … y'all become the idea), there's nothing out in that location that matches the Pi's unique mix of accessibility, supporting community, accompaniment ecosystem and outright affordability. And the Raspberry Pi 4 delivers all of that with better features and more ability than its predecessors, all for the aforementioned low price.
The Raspberry Pi 4 Model B is the best estimator out in that location for tinkering and creating, hands down.
