Late Friday afternoon, I obtained an thrilling SMS notification—my assessment pattern of the brand new Raspberry Pi 400 had arrived. I discovered of the brand new Pi mannequin final week whereas interviewing Raspberry Pi founder Eben Upton and Canonical desktop engineering director Martin Wimpress about Ubuntu 20.10’s newly improved desktop help for the Pi {hardware} household.

Briefly, the Pi 400 is a barely quicker model of the 4GiB Pi 4 which ships preassembled in a small, wedge-shaped chassis with built-in keyboard. The brand new mannequin immediately targets desktop alternative use and could be bought solo for $70 or as a full equipment (as seen above) for $100.

The brand new kind issue—which has apparently been within the works ever because the introduction of the official Raspberry Pi keyboard—addresses and enthusiastically helps the Pi 4’s rising use case as a alternative or various for the standard desktop PC. Upton informed Ars that the Pi 400 is about 20 p.c quicker than the Pi 4; it has largely the identical elements beneath the hood however on a in another way laid-out board, and its BCM2711 CPU is clocked a contact larger than the BCM2711 within the Pi 4.

Unboxed and plugged in, the Pi 400 is purposeful however not significantly beautiful. On the plus facet, the built-in keyboard means one fewer cable to cope with. Sadly, the remaining cables are unusually more likely to snarl and look a bit feral. They’re each stiffer and shorter than I would want in an excellent world, making it difficult-to-impossible to finish up with a setup that does not appear like a rat’s nest. The purple cable for the mouse clashes fairly violently with the off-white cables for USB-C energy and micro-HDMI out, which does not assist any.

That mentioned, it is necessary to keep in mind that your complete equipment retails for $100. Throughout the limits of the Pi 400’s very beneficiant worth, it is probably not honest to complain too laborious about a couple of aesthetic gaffes right here and there! Customers with a couple of further {dollars} to spend would possibly wish to think about changing the Pi 400’s mouse with one thing a bit extra purposeful, although… and a full-sized keyboard may not be a foul thought when you’re at it.

The built-in keyboard is purposeful however a strong 4 inches narrower than a regular keyboard. I am not typically delicate to variations in keyboard structure because of an extended profession involving Different Individuals’s Computer systems in massive numbers, however I used to be plagued with fixed mistyping issues your complete time I examined the Pi 400.

It is also price noting that, whereas the Pi 400 helps twin shows, it does so with micro-HDMI ports, not full-sized ones—and it ships with a single cable. You will want an additional cable if you wish to use your Pi 400 with twin shows—and because it ships with a micro-HDMI to HDMI cable, not an adapter, issues will get sophisticated if you wish to use it with, e.g., moveable LED shows which have off-sized ports themselves.

Lastly, there is no 3.5mm audio jack on the Pi—in case you’ve obtained it hooked to a tv or a monitor with audio system, it may possibly ship audio over HDMI; in any other case you may want a supported USB audio system. I examined with a cheap USB gaming headset, which labored nice.

Impressions—Raspberry Pi OS

I started testing the Pi 400 utilizing its native Raspberry Pi OS Linux distribution—which is mainly Debian with XFCE4 and plenty of middleware optimizing it for the Pi. Sadly, there’s virtually nothing in the way in which of normal benchmarking utilities which run on ARM Linux—all I may discover was the Phoronix Take a look at Suite, which might have required extra time to run than I needed to take a look at the system in complete. So for probably the most half, I’ll discuss my subjective expertise, slightly than laborious numbers.

The excellent news in regards to the Pi 400 is that it does make a reputable desktop PC, within the sense that, sure, you may completely use it with out issues breaking. With that mentioned, you are unlikely to overlook that you just’re utilizing a really cheap ARM system. Very similar to the Pinebook Professional, the Pi 400 displays heavy latency when opening functions that is maybe attainable to reside with however not possible to not discover.

Additionally just like the Pinebook Professional, as soon as the functions are literally open, they often run easily sufficient—though we did discover the Pinebook Professional’s hex-core 2.0GHz large / 1.5GHz little CPU noticeably punchier than the Pi 400’s straight 1.8GHz quad-core. The most important downside I had was with high-resolution, high-frames-per-second YouTube movies.

I solely examined the Pi 400 with a 1080p monitor, so I can not converse to its chops with 4K movies—however it’s completely not able to dealing with the Costa Rica in 4K 60 fps HDR video with out seen body drop, even at 720p. The key situation right here seems to be the 60 fps price, not the 720p decision. I additionally examined Netflix’s Our Planet—Forests on YouTube at 1080p, and that video performed again flawlessly.

Inspecting CPU utilization throughout playback of the 60 fps Costa Rica video, we are able to see the little 1.8GHz Broadcom quad-core CPU struggling—it is at its limits, with CPU utilization for all cores at greater than 90 p.c. Though the BCM2711 helps {hardware} offload of video decoding—with out which, this video could be taking part in in seconds per body, slightly than simply dropping frames a bit—the {hardware} offload can solely accomplish that a lot, and the CPU is being requested to tackle greater than it may possibly deal with in software program.

This impact is much more seen when getting into or leaving full-screen playback. On a regular desktop PC, that operation takes maybe 100-150ms. On the Pi 400, it continuously takes as a lot as three or 4 full seconds, throughout which the video itself tends to maintain taking part in, however the surrounding controls and framework solely partially render / cease rendering whereas the shift finishes happening.

Getting audio out of the Pi 400 was a little bit of a problem; it defaulted to trying to ship audio over HDMI, and Raspberry Pi OS’s audio management dialog is not one of the best. Even after altering the output system to USB Audio (my gaming headset), YouTube wasn’t producing audio—and there is no “take a look at” button I may discover in Pi OS, just like the one in Ubuntu’s audio management dialog. Closing and re-opening the browser completely after altering the output system resolved the problem, and audio performed from the headset nice afterward.

All of those quibbles apart, I once more should make observe of the sheer inexpensiveness of the Pi 400—it is solely $70 for the system itself, or $100 for a equipment which features a mouse, SD card, micro-HDMI to HDMI cable, USB-C energy provide, and 247-page full-color information packed chock stuffed with suggestions and initiatives.

At $100 or much less for a purposeful, dependable, well-packaged and built-in desktop computing system, I am not going to get mad about YouTube wanting humorous and hanging for a couple of seconds when it shifts forwards and backwards from full-screen. Sure, Walmart’s $350 Gateway laptop computer is significantly extra highly effective, and features a display, battery, and significantly better keyboard… however that $350 would purchase 5 Raspberry Pi 400s.
