The Raspberry Pi Foundation's single board PCs have generated a lot of buzz over the past decade due to the low price and the many features of the product. Three years have passed since the non-profit organization launched the Raspberry Pi 3, which is almost an eternity in the world of technology. Still, the Raspberry Pi 3 still occupies an influential position in the market. Now the Raspberry Pi 4 is ready to take the place of his predecessor. Without further ado, let's take a look at what the latest Raspberry single board computer has to offer.
The Raspberry Pi 4 essentially looks like the Raspberry Pi 3. Since it's all about chips and pieces of metal soldered to a PCB, that's to be expected. The Raspberry Pi 4 is slightly larger than its predecessor, but not by a significant margin.
At the heart of the Raspberry Pi 4 is a Broadcom BCM2711 SoC with four 1.5 GHz ARM Cortex-A72 processor cores. This should offer a significant performance improvement over the Raspberry Pi 3 Model B +, which used four slower, more energy efficient Cortex-A53 cores at 1.4 GHz. The Pi 4 also has a more powerful graphics processor running at 25% faster than its predecessor. The architectural details of Boardcom's patented VideoCore graphics technology are rare and we can not really judge how much performance this represents, but it is likely to be quite significant because of the only faster clock speed.
All versions of the Raspberry Pi 4 will also be equipped with LPDDR4, which is significantly faster than the LPDDR2 used on the outgoing Pi 3 model B +. The cheapest model in the Pi 4 will have 1GB of RAM and will cost $ 35 exactly like its predecessor. Poneying an extra $ 10 will give you 2GB of RAM, and the top 4GB version will sell for $ 55.
With the combination of faster processing hardware, faster RAM and a greater amount of RAM, it appears that the Pi 4 will run circles around its predecessor in virtually no time. Any task. It should also be noted that the Pi 4 will also support Gigabit Ethernet and USB 3.0 ports, features that were missing from Pi 3.
Although the Pi 4 is undoubtedly the fastest product ever launched by the Raspberry Pi Foundation, it is unfortunately also one of the most fashionable. When using the system to watch a YouTube video in 1080p, PCMag recorded a SoC temperature of 72 ° C. The temperature reached 76 degrees Celsius during the JetStream test. Technically, it is prudent to use the Raspberry Pi 4 at these temperatures and the system is designed to throttle the processor if the temperature reaches 80 degrees Celsius to prevent damage to the device. But it is also a bit close for comfort and it would be better to invest in a fan, a heat sink or both to protect themselves from damage related to heat.
All things considered, the Raspberry Pi 4 is a faster solution with a richer feature set, while matching the price of its predecessor to the penny. Not to mention that there are models with more RAM for those who wish to use the system as a HTPC device or streaming media. In fact, I do not see a single negative point to make about it. Just be careful not to burn your Pi with too many energy-hungry applications.
The Raspberry Pi 3, in its various models, began to have temperature problems because it uses a ARM processor this, although it does not require dissipation, during very intensive tasks or overclocking, it was necessary to place at least one passive heatsink on the top of the chip.
Now, these problems seem to remain with the Raspberry Pi 4, which was very hot at launch, forcing the Raspberry Pi Foundation to launch a firmware update that resolves these issues. The plate begins to suffocate thermally when it overcomes the 80 degrees to reduce this temperature, which is reached when a high CPU load is maintained for a long time. To do this, you must reduce the frequency and therefore the performance.
With the firmware, they have managed to reduce the temperature between 3 and 5 degrees under most conditions, but the problems persist depending on the system installed, the loads or the overclocking. This is reported by a multitude of users in the Raspberry Pi forum of society, with more than 250 messages.
Interestingly, in this link, we can see how James, the company's main software engineer, makes fun of people who have temperature problems and calls him "troll", telling him that if the Raspberry Pi 4 looks good , do not use it The user who unveiled the problem already called troll and complained when he reported the initial temperature problems that triggered the firmware that tries to solve them.
This same user was trying to use the card in a box with which he had temperature problems because the heat was accumulating there. Even putting a radiator on the chip could not be solved either. Therefore, he finally put a radiator of 28 x 28 x 20 mm and a fan of 30 x 7 mm on the case to continue to use it. This solved their problems because at rest the plate is at 35 degreesand when the four nuclei are at maximum performance reaches only 45 degrees.
So even if the Raspberry Pi 4 uses a chip 28 nm over 40 nm a 3 B +, it runs more frequently and generates more heat. If you plan to use it and want to reduce its performance, some small radiators will save you a lot of headaches. And if you use a box with holes on top, better.
The Raspberry Pi Foundation launched the Raspberry Pi 3 about three and a half years ago, and the single card computer has proven extremely popular. There have been some variations of the Pi 3, but the time has come for a real successor. The Raspberry Pi 4 offers a more powerful processor, 4K video output and additional connectivity options.
Like the old Raspberry Pi devices, the new Pi 4 is a compact computer with almost everything you need on one board. There are USB ports, video output, processor, RAM and even GPIO expansion pins. However, you do not need to switch to the microSD card for storing and loading the software.
The Raspberry Pi 4 retains the same shape and size as previous versions, but is faster and more efficient. The Pi 4 has a new processor, the Broadcom BCM2711. It has four Arm Cortex A72 cores operating at 1.5 GHz. In comparison, the Raspberry Pi 3 had four Cortex A53 processors. You'll find the two A72 and A53 cores in popular smartphone chips, the A72s serving as high-power processors and the A53s as slower and more efficient. So, this is a big update for the Raspberry Pi.
The faster BCM2711 allows the Raspberry Pi 4 to achieve unthinkable feats with the Pi 3. It can decode 4K videos at 60 fps using HEVC / H.265 graphics, OpenGL ES 3.0 and can even export 4K videos on a monitor. There are two micro-HDMI ports on the Pi 4, but you only get the 60 Hz output on a single monitor. With two, the Raspberry Pi 4 can only 30 Hz. The transition to the HDMI microphone is a little painful. These cables are much less common than the HDMI standard on older versions of the Raspberry Pi.
Some of the previous Pi's incarnations ports also benefit from an upgrade. Two of the four USB 2.0 ports are now USB 3.0 and the micro USB power supply is now USB Type-C. The Ethernet port also supports gigabit speeds.
This version of the Raspberry Pi comes with 1GB, 2GB or 4GB RAM. Each upgrade adds 10 € to the starting price of 25 €. The Raspberry Pi Foundation also produces its own accessories for the first time. It will offer a kit including 4 GB Raspberry Pi 4, a case, an SD card, two HDMI cables, a keyboard and a mouse for $ 105. Just add a monitor or two and you get a fully functional computer. The Raspberry Pi 4 is available for purchase today at several retailers.
NASA's Jet Propulsion Laboratory (JPL) uses some of the most advanced technologies in the world, including Martian rovers and space telescopes. However, it was a relatively simple consumer technology that allowed hackers to enter its network and steal data. According to a report from the Office of the US General Inspector (OIG), someone connected an unauthorized Raspberry Pi JPL, which allows hackers to enter the systems.
The full federal review of JPL systems was created following an incident that occurred in April 2018 when a person at JPL linked the Raspberry Pi to the network there for an unknown purpose. This small computer had an unfiltered connection to the Internet, acting as a beacon for hackers. It was apparently simple for unknown assailants to enter systems connected to the same network as the Raspberry Pi.
While inside the JPL network, hackers allegedly stole about 500 MB of manned flight data. If they were only a few jokers on the Internet, these data would not be very useful. If, however, they represented an adversarial country, the data could be extremely useful. This would be pretty serious, but the BIG review has deepened and revealed other issues related to how JPL manages its networks.
After ransacking the JPL computers, the attackers found a deeper route into the JPL network. They were able to access sensitive systems like the Deep Space Network, a set of radio antennas that NASA uses to communicate with distant spacecraft. The security breach was so serious that Johnson Space Center officials decided to disconnect from the JPL network to protect projects such as the Orion crewed multi-purpose vehicle and the International Space Station. Johnson remained disconnected from the JPL until November 2018, but some connections are still restricted.
The Office of the Inspector General stresses the shared nature of its network. A properly segmented network would have prevented attackers from setting up in other systems and threatening air operations. The system used by JPL to track network hardware is apparently incomplete and poorly maintained. Network administrators even admitted that they did not regularly check the list of new devices.
NASA and JPL are committed to resolving the issues outlined in the report, and the BIG will be back on track to make sure this happens. We can not take risks with major projects like the Artemis program.
Kano PC, a company apparently dedicated to building inexpensive computer blocks to familiarize children with hardware and coding, has teamed up with Microsoft to offer a Windows 10 laptop to assemble that kids can assemble themselves.
Historically, building a PC was a difficult undertaking. At the time when I was a kid, finding a village blacksmith who owned the proper molds to mold the PCB to mold a motherboard was challenging. Once you have enough copper wire from the Ogre pit, you need to shred a good Mountain Performance depth clock and sacrifice it to pass to the three gods of peripheral support: IRQ, DMA and I / O range .
If your prayers (and your questionable driver code) were accepted, a new one would be added to your delicate stack of magic and circuits. Otherwise, run the FranticRepair function, making an all-night effort to restore the family computer in the state it was in before Your parents went to sleep the night before.

Very well JamieIt was not really remove that bad. But building laptops has always been really difficult. This type of simplified construction kit will not give you a high-end system, but a way to introduce children to the idea of building their own own system to carry around the house and inevitably break, it's a good idea.
The technical specifications on the Kano PC include:
The device will work under Windows 10 S – the locked variant that should not be a problem with a device like this – and comes with some Kano-specific included applications, such as How Computers Work, Create Artworks Art, Kano App, Paint 3D, Kano Projects and, not to touch, Microsoft teams. (Seriously, this is a feature of the software listed).
In kits, however, the idea of building a small laptop as a child's system is appealing. The $ 299 Kano PC will only be available in October, but if it is up to its appeal, it may be a day off for a child interested enough to start learning how to build them.
It is unclear whether this version of Windows 10 S can be converted back into a real version of the operating system as are other computers running 10 S. If that is the case, it should be act of an excellent little computer for the first hands. Variants based on Linux and RBP are also available (and Kano builds different kits designed for these spaces), so that users have options depending on which operating system you prefer. Of course, there would be nothing s & # 39; stopping Someone is trying to load Linux into this case (and I'm sure someone will try), but the value-added software included by Kano is probably supposed to be a reason to stay with the Microsoft loadout. .
Since the announcement of the Atari VCS, questions have arisen about the recipient of this system. The original Atari is long dead, the games in question are widely available on many platforms, and games like Pong, Adventure and Combat, as worthy as they are in terms of history of the video game, have not withstood the long-time popularity of Super Mario Bros. or even Sonic the Hedgehog.
To his credit, Atari's VCS project has long understood that it would not be able to market its hardware as a pure retro box as Nintendo, Sony and Sega currently do. Instead, the company tries to emphasize the openness and flexibility of its system. Atari VCS will use the Ryzen 1606G. This is a Zen version with two cores / four-wire, clocked at 2.6 GHz and capable of increasing up to 3.5 GHz. It is associated with a Vega 3 processor core (192 shader cores, 1.2 GHz). This is not a big hitter, as far as processors or GPUs are concerned. It has a custom Linux operating system (not yet much knowledge about its capabilities in this area) but supports Windows 10. FreeSync, however, is not supported.
Reading the recent reports, it's hard to see how this product actually finds a market. Ars Technica note "The example provided by Atari of a" modern "game running on the system was a Linux version of Borderlands 2, a 2012 title that was frankly debuting at a rather unstable pace in the demonstration of our sequel to 39; hotel ". This is no wonder, considering its running on a 2C / 4T embedded processor with 192 GPU cores and DDR4-2400 RAM. It might be possible to use a streaming service like Stadia or xCloud on Atari VCS, but why would you buy one specifically for these services?
Atari would like to point out that the VCS is open to DIY like other consoles, and it's true: you can swap RAM and SSD, install other operating systems, and even develop games on the VCS. submit them to Atari's own store. These are very good ideas, and the idea of being the "Raspberry Pi" of the show even has some appeal – but has not she tried to put something very similar on the market? According to VCS executives, the problem was that they were locked in the Android ecosystem and posed a whole host of problems that were condemning the console. It's an interesting catch.
THG has information on product references. The 400 Onyx will have 4GB of RAM but it will miss an internal M.2 drive (all versions of the VCS have USB 3 ports to connect external drives). The 800 Onyx base has an internal M.2 drive, while the 800 Onyx All In will actually include joysticks and an SSD (unspecified size). Controllers are extra, unless you buy the high-end retail package.
Oh, and everything will happen in the spring of 2020.
I've been pretty tough with the Atari VCS over the years. I must congratulate the company for proposing a semi-unique product: it contains elements of the console space, with additional flexibility. But at the end of the day, the so-called "Raspberry Pi" of the show has a really critical problem – that's 10 times the price of the RBP of origin. Between a VCS and a PlayStation Pro, you'll certainly get better with the Sony system. Or a switch. Or an Xbox.
It was probably really hard to resurrect a system and a brand like these, but it seems that something is still missing from this package. The nostalgia of the Atari brand is not going to lead to a wave of homebrew coders who are trying to write software for a badly undernourished embedded chip. I will not say that it's bad, but it's very difficult to understand who would want this product and why.
