5G smartphones expected to grow by 130% this year năm The pandemic has changed everything, and the needs of users in the smartphone market have also changed. The strong growth of 5G in countries around the globe also leads to a slowdown in demand for 4G devices, and 5G devices will record strong growth and gain a lot of user interest. The smartphone market has returned to growth from last year and continued to grow in the first half of this year, said Ryan Reith, IDC’s vice president of global mobile device tracking. In addition, the price of 5G devices continues to decrease as 5G Android devices will drop 12% year-on-year in 2021, which is a great pressure for Apple devices as its prices are still higher than other devices. others. IDC also expects growth through 2025, with a 5-year compound growth rate of 3.7%. The smartphone market will not be affected by the lack of semiconductors such as automobiles, computers and consumer technology categories. In addition to 5G Smartphones, IDC also reports on the PC market this year. Desktop, laptop and workstation shipments are expected to increase this year despite ongoing semiconductor shortages. IDC’s new forecast in the Worldwide Quarterly Personal Computing Device Tracker says PC shipments are expected to grow 18.1% to 357 million units this year.

Flashing screen. The cause of this error may come from the application, software and display driver conflict with each other. Some are named by Microsoft as Norton Antivirus, iCloud, IDT Audio. So how to find out and fix this problem? Please refer to the following content. 1. Determine the cause of the “tearing” error on the screen of Windows 10 Start Task Manager up. Next, please observe the screen closely to see if the Task Manager blinks continuously or continuously… if so, check the display driver you have installed. On the other hand, if everything but the Task Manager is flashing, the cause lies in the application or software. 2. Fix the “tear” error on the screen of Windows 10 If the problem is determined to be an incompatible application or software, check to see if you are running Norton Antivirus, iCloud, or IDT Audio in the background. These software, applications can cause screen flickering in Windows 10. If not using this software or application, consider recently installed settings. Another type of software that can affect the screen is desktop software like the Live wallpaper program. If yes, disable or uninstall it. If you suspect a certain software or application, try updating it to the latest version. If it still doesn’t work, you need to uninstall it. If you determine the cause is due to the driver, try updating to the latest version to see if the problem is resolved or not. If you don’t know how to update, you can use some third-party applications to help find and install the latest drivers for your system such as Driver Talent, Driver Booster and Driver Genius. If you want to update the driver manually, do the following. Right-click the Start button and select Device Manager. Find the hardware section Display adapters and click the arrow icon. Right-click on the display driver name and select Update Driver. The driver update option dialog box appears, please click Search Automatically . If Windows finds a newer version of the display driver, it will automatically download and install it. In addition, the error of “tearing” on the screen of Windows 10 can also be caused by screen refresh rate of the task you are working on is not compatible with the system so it could be the cause. Therefore, if possible, try changing the screen refresh rate. In addition, the “magnetic field” can also cause the “tear” error. Try moving the computer to another place, away from electronic devices, and check if the screen is still faulty. If it does, it could be caused by a faulty display. You should test by connecting to another monitor. If there is no error when connecting to another monitor, you need to replace the screen. Hopefully the above solutions can help you fix the “tearing” problem on the screen of Windows 10.

Among them, e-commerce and digital payments are booming with an increasing number of users. However, there has not been much breakthrough in the value of digital payments due to consumer confidence and spending considerations amid the crisis. It is estimated that with the expected recovery of the economy after the pandemic, the value of digital payments will increase by 30% to reach $15 billion this year. According to Appota, in 2020, 121 startups have been providing fintech services. The number of digital payment startups accounted for 31%, more than twice that of peer-to-peer lending companies (16%). As of September 2020, Momo reached 20 million users, becoming the most used payment platform in Vietnam. Meanwhile, intermediary payment service provider VNPay has become the second unicorn startup and one of 12 companies in Southeast Asia valued at $1 billion. Obviously, the digital payments market is very potential but also highly competitive. Due to the implementation of social distancing measures, more and more people are staying at home and using mobile apps online. Short-form video application TikTok has reached 16 million downloads in Vietnam, becoming the latest entertainment trend of users. The market segment is expected to be more active in 2021 with the expansion of Instagram and Youtube. Meanwhile, the online games segment also recorded dizzying growth with 40% growth in revenue, new game downloads and releases reaching $205 million in 2021.

Google Chrome 90 on macOS and Linux does not appear to be affected. Photo: MINH HOANG A Google product expert seems to have identified the problem. “It seems that this issue is related to the User Data folder of the computer, so using Google Chrome (beta) should solve the problem.” However, if you just want to use the stable version of Google Chrome, you can follow these steps to prevent problems. First, close the browser and press the Windows + E key combination to open File Explorer, then paste the %LOCALAPPDATA%GoogleChromeUser Data link in the address bar and press Enter. Next, delete the Local State file, then reopen the Google Chrome browser. If the problem is still not fixed, the user can simply go back to %LOCALAPPDATA%GoogleChromeUser Data, copy everything here to another place, such as the Desktop. Then, rename the User Data folder to any name (different from the old name) and reopen the Google Chrome browser. Currently Google has confirmed the issue, and it will probably be fixed in the near future through a new update.

AMD recorded 8.9% growth in the first quarter of 2021, the highest in 15 years In 2020 and into the first quarter of 2021, AMD has focused on high-end desktop CPUs and EPYC chips for servers. The first quarter of the year recorded a record increase of 41% over the same period last year, which is the highest number for the CPU market in 25 years. AMD’s biggest growth most recently came in 2006, when the chipmaker saw its server CPU market share increase from about 5-7% to about 22% in just 18 months with the 64-bit Opteron processor. bits. Then, Intel overtook AMD to let Intel regain its leadership in technology and hold it for 10 years. AMD has launched EPYC Milan and it is used for data centers and supercomputers. Consistent growth in the first quarter will propel AMD further in its goal of becoming a leader in the server CPU segment. The choice of EPYC chip has proven that AMD’s direction is appropriate in recent times. One question is what the growth of ARM architecture means for ARM and Intel in the near future, while Nvidia, Microsoft and others are gradually moving to produce ARM-based CPUs. As for Intel, most recently launched Rocket Lake processors and they compete directly with AMD Ryzen 5000. However, Intel’s chips are more commonly found in retail stores at very affordable prices. competition while AMD’s chips are still rare on store shelves. AMD still has a strong portfolio of next-gen EPYC CPUs such as the 4th Gen EPYC Genoa chips that are expected to be announced next year and will feature the all-new Zen 4 core architecture and a host of other features to addresses Intel Sapphire Rapids & Granite Rapids Xeon CPUs.

The security hole exists for more than 3 years, but Intel has not been able to fix it. Photo: CIO Indeed, 3 years have passed, and there is still no end to the vulnerability. Meanwhile, experts from the University of Virginia and the University of California, San Diego, have discovered a new attack method that bypasses all current Specter protections built into the chip. This attack method has the potential to put almost any system – desktops, laptops, cloud servers and smartphones – once again at risk. Revealing Specter ushered in a wave of more powerful attacks, allowing malicious code to directly read passwords, encryption keys, and other valuable information from the computer’s kernel memory. Although chip manufacturers such as Intel, ARM and AMD already know this and combine defenses to reduce the threat from vulnerabilities, the methods have not yielded the desired effect. A Specter attack is capable of tricking the processor into executing instructions along a wrong path, the researchers say. Even though the processor recovers and completes its task correctly, hackers can still access confidential data while the processor goes in the wrong direction. The new attack method exploits what is called a micro-operator buffer (called micro-ops), an on-chip component that breaks machine instructions into simpler instructions and speeds up computation, like a secondary channel to reveal confidential information. Micro-op cache is built into Intel processors, manufactured since 2011. According to researchers at the University of Virginia, Intel’s defense proposal against Specter (called LFENCE) is to place sensitive code in a waiting area until security checks are done and only then the code Only sensitive is allowed to execute. However, research has shown how attackers can steal information through micro-op caching and use it as a secret channel. Although exploiting the Specter vulnerability is very difficult, the researchers say that with computers with a lot of sensitive data, hackers do not mind the difficulty. To protect the system from the new attack, the researchers propose to clear the micro-ops cache. This is a technical solution that comes at the expense of performance benefits. According to the researchers, micro-op caching has some dangerous effects. First, it ignores all caching reduction techniques such as side channels. Second, attacks in this zone go undetected like an existing attack or malware. Third, because the micro-op cache is at the front of the path, prior to execution, Intel’s Specter protections or recommendations to limit cache updates are still compromised. public.

Intel is pushing partners to sell Intel Evo laptops using Tiger Lake chips. In 2020, Intel launched the 11th generation Intel Core mobile processors collectively known as Tiger Lake. This new chip is introduced with outstanding performance, real-world battery life of 9 hours or more using FHD screen, fast charging and stable response. The Intel Evo concept is a standard set for all high-end laptops equipped with this new line of Intel chips. Continuing from 2020, this year Intel has a plan to develop and boost sales for the Intel Evo brand. Intel’s partners will also be part of the plan, and Intel wants to give them promotional tools to sell more devices. Reply CRN Steve Long, Intel’s global vice president of computer sales, said that this year will be the year of investing in customers’ businesses. In addition to investments in Intel partners and products or programs, but also in market access. The tools Intel says will be the most advanced tools that give partners access to schools or educational institutions. These are the places that will need a lot of laptop devices to organize teaching for students. According to statistics, with 1.6 billion students in the world, only 5 out of 100 students have laptops to use. Alder Lake will be Intel’s next generation of chips to appear next year. The business segment also has room for growth in laptop sales as the need to work remotely from home is increasing and becoming a trend for many companies. As for the next generation of Intel chips, at the end of Q2, the Intel Lake H45 laptop will be released. For desktops, Intel will also introduce the first 10 nanometer technology Alder Lake processors. Demand for a laptop or Chromebook is growing, especially in the second half of 2021 and into 2022, as well as in the following years. Intel is expanding its policy to reach customers in different segments and deliver high quality products.

Illustration. Although this impressive growth rate is partly due to the already bleak first-quarter sales of 2020, there is no denying the positive signal of the technology market in recent months. With 82.7 million units delivered to consumers, this is the highest sales volume in the first quarter of the year since 2012. The main driver of growth in the personal computer market has been on the back of small businesses rebounding after a tough pandemic year, with the emphasis on laptops. According to records, sales of this model reached 67.8 million units in the first quarter of 2021, up to 79% over the same period last year. For its part, the desktop computer business also prospered after a bleak year, but has yet to come out of the decline. A total of 14.8 million desktops were sold in the first three months of 2021, down 5% from the same period in 2020. The strong market recovery in the first quarter of 2021 indirectly helped five manufacturers Export leader (accounting for 78% of total market volume) achieved double-digit growth. Specifically, Lenovo – the market leader with 25% market share – sold 20.4 million units in the last quarter, up 61% over the same period in 2020. For its part, HP – thanks to a boom in sales. Chromebook line (cheap computers using Google operating system) – “came in second” in the first quarter of the year with 19.2 million units sold (up 64% over the same period in 2020). In third place is Dell, with modest growth compared to the two competitors, only 23% (equivalent to 12.9 million units sold). This contributes to the US computer company’s market share continued to decline, currently only 15.7% – much lower than the 19.6% recorded after the first quarter of 2020. The other two names in the top five selling PC makers were Apple and Acer, with 6.6 million and 5.7 million units sold, respectively. However, these are the brands with the best growth in the first quarter of 2021 compared to the same period last year, respectively 105.2% and 82.1%. Forecasts about the market outlook for the whole year 2021, the analysts are optimistic in the context that businesses and organizations start to regain investment in technology infrastructure. However, the supply shortage will still slow the growth of the computer market, leaving many opportunities wasted. In that context, experts urged governments to soon increase investment to support the production of semiconductor components, in order to soon remove these bottlenecks.

By 2021, the total number of personal computers (laptops and desktops), tablets and smartphones will reach 6.2 billion units globally, according to the latest forecast from research firm Gartner. .

According to the report, the number of laptops and tablets in use by 2021 will increase by 125 million units compared to 2020. By 2022, the number of these devices globally will reach 6.4 billion units, an increase 3.2% compared to 2021. Gartner believes that the number of laptops and tablets will increase by 8.8% and 11.7% by 2021, respectively. will decrease from 522 million units in 2020 to 470 million units by 2022.

Although the number of smartphones will decrease by 2.6% by 2020, it will increase by 1% by 2021. Ranjit Atwal, Gartner Senior Research Director, said: “The pandemic has permanently changed the way the device is used. employee and consumer Family education has shifted to digital education, interactive games to cloud computing… The variety and number of devices will continue to increase ”.

Gartner also predicts a 32% increase in PCs in Q1 2021, to 69.9 million units over the same period last year. This is the fastest growth rate in 21 years. During a pandemic, people need computers to work from home or study online. Shipments in Q1 this year remained the highest since 2015 of 71.7 million units.

Lenovo is still the largest PC maker in the world, with 25.1% market share, up from 23.3% a year ago. HP and Dell ranked second and third with market shares of 21.4% and 16.5%, respectively. Apple, Acer and Asus ranked fourth through sixth.

According to Gizchina

There are many products that need to be charged when traveling or going out, so several charging heads will occupy a lot of backpack space. Even if it is used on a table, the bulky charging head is extremely unfriendly to the socket design. Obviously there are two socket positions, but often after one is plugged in, the other cannot be plugged in properly. I believe that many friends will have some adverse reactions to the picture below.

In response to the strong demand for small-size and high-power charging heads, GaN charging head technology emerged as the times require. Gallium nitride is an inorganic substance with the chemical formula GaN, a compound of nitrogen and gallium, and a direct bandgap semiconductor. For charging equipment, the biggest advantage is that while the charging equipment can maintain high power output, the volume of the equipment is further reduced.

The protagonist to be introduced today is the Aohi Magcube 30W fast charge charging head made using a new generation of gallium nitride GaN+ technology. Aohi may not be familiar to everyone, but in fact it is a smart brand under the listed company Aohai Technology, and Aohi Technology is the core manufacturer of original chargers for many domestic and foreign mobile phone brands such as Huawei, Xiaomi, OPPO, and vivo. Under such a strong R&D background, the products it launches are naturally worth looking forward to.

The product packaging is in a cool black design style, with a square flat outer box with the appearance of the charging head printed on it, and the overall packaging also highlights the characteristics of compactness.

It can be clearly seen from the specific output data on the back that this charging head can support a variety of output powers, including: 5V/3A, 9V/2.22A, 9V/2.77A, 15V/2A, 20V/1.5A or 3.3- 11V/3A, yes, the peak value can even output 33W high power in an instant. The focus is to support fast charging protocols for many devices, including Apple 2.4A, Samsung 5V/2A, Samsung AFC, QC2.0, QC3.0, QC4.0+, DCP, FCP, SCP, PD 2.0 and PD 3.0 protocols . Among them, the relatively rare 15V/2A, 20V/1.5A high-voltage charging in the mini charging head can have better charging power when charging large devices such as notebooks or tablets.

But of course, high-power fast charging such as Huawei, Xiaomi, OPPO, and vivo are basically proprietary protocols, and naturally they can only shake hands with the general PD or QC protocols.

The packaging inside the box is also very simple, just a charging head, manual and warranty card.

The volume control of the Aohi 30W fast charging head is indeed very good. The specific size is actually not much different from Apple’s previous “Five Fortune and One An” charging head, but the output power is properly 30W.

If compared with the 30W charging head of the MacBook Air and the 20W charging head of the iPhone, the gap is even more obvious.

In addition to excellent volume control, its own workmanship is also quite solid, and you can feel the feel of the thick and solid material when you pick it up. The shell has also reached a fire rating of 94V0. There is also a metal CNC cutting outer ring on the Type-C interface, which is not easy to deform after long-term plugging and unplugging. There are also finely carved patterns on the shell and even a charging status indicator. The workmanship design is indeed a lot of work.

The charging status indicator also corresponds to the three charging states (three-color LED lights). In the low current mode, it is a green light, the normal mode is a blue light, and the fast charge mode is an orange breathing light, which is very intuitive .

In fact, for most users, even if they know how many charging protocols it supports, it’s not as convincing as to test it on a real device directly, so the next step is to go directly to the test link (in order to trigger the fast charge normally, the remaining power of the following devices is 45 % Or less).

Test Samsung Galaxy S21 Ultra, successfully trigger Samsung’s 9V fast charge, the peak charging power is about 25W.

Recently, the newly launched OnePlus 9 Pro, because its Warp fast charge is a private charge pump protocol, so here is to trigger the PD charging, and it also has a power of about 18W.

The 65W fast charge of OPPO Find X3 Pro is also a private protocol, but it can also activate PD fast charge normally, and the peak power is about 17W.

Xiaomi Mi 11 Ultra successfully triggers PPS fast charge, and the charging power at this time is also about 25W.

And Xiaomi Mi 11 also supports triggering PPS fast charge. All Xiaomi Mi 11 series with this charging head can see the indication of fast charging in the charging interface.

Charging the Huawei Mate 40 Pro can normally trigger the PD charging power of about 12W.

The Meizu 18 Pro, which is more friendly to PD charging, successfully triggered a fast charging power of about 26W.

In some mobile power supplies that support PD fast charging, it can even support peak fast charging of about 21W, and the time to “return blood” to the mobile power can be effectively reduced.

Charging the iPhone 12 can trigger a fast charging power of up to 20W when the screen is turned on under low power. It can also meet the needs of fast charging while playing and charging, and the effect is very good.

The vivo mobile phones are not good for PD and QC high-power compatibility, and insist on their own private protocol, so the power of PD charging is still not high, which is mainly related to the mobile phone.

It can be seen that the Aohi Magcube 30W charging head has excellent PD or QC fast charging compatibility for most mobile phones. What about the charging support of tablets, laptops or handhelds?

When paired with iPad Pro, you can see that it can trigger the 15V high-voltage mode, basically running full 30W fast charge, and the effect is good.

On the MacBook Air, a large voltage of 15V is also triggered, which can reach a fast charge of about 30W. In such a comparison, the volume of Apple’s official 30W fast charging head is even larger.

Perform a charging test on Nintendo Switch, which can also reach about 16W, successfully triggering fast charging.

For some small devices, such as Bluetooth headsets, it also normally triggers the low current mode, which can effectively protect the battery of the small device.

After actual testing of various devices above, you should have a very intuitive understanding of the PD fast charge compatibility of Aohi Magcube 30W. In order to facilitate the collection of models, most of the above tests only choose newer devices. This does not mean that compatibility with older devices is not good. As long as the device in your hand can support fast charging such as 18W PD or PPS, then this charging head can provide a good fast charging experience.

In fact, the benefits of this ultra-mini GaN charging head are not only fast charging compatibility, but more importantly, it can effectively save desktop space.

Even if it is extremely extreme with the Aohi charging head plugged into the power strip, there is still space between the charging heads, and it will not encroach on the position of other charging plugs. This is also conducive to the heat dissipation of the charging head itself, and it is not necessary. Endure the random charging head on the desktop.

For example, in the company office scenario, the demand for fast charging of the device’s private protocol is not too great, and PD fast charging can be used by plugging it in. Except for some devices that do not support high-power PD, the others have already met the fast charging experience of about 18-30W, and the charging speed will naturally not feel slow.

Even if you need to bring a few more charging heads to go out, this small-sized GaN 30W charging head is also very friendly to backpacks and shoulders. It is compatible with most devices and ordinary 3A data lines, and the user’s use cost is relatively reduced.

Of course, this charging head is only 30W at the highest. The charging speed and power are definitely not as exaggerated as the 65W and 120W of some private agreements, and it is difficult to meet the high load demand of PD 65W and 100W notebooks. But in terms of its portability and the need to replenish power during idle time, this should be a product currently on the market that has the best experience in terms of charging power, support protocol and volume.

What’s more, it is really the only Aohi that can achieve 30W fast charging of GaN in this volume.

Aohi Magcube 30W has also launched a public test campaign on the tail public test platform. Those interested in the tail can actively participate in one, and users who have not won the lot can also jump to its official website to follow on our public test page. The latest price developments.
