At CES in January this year, AMD demonstrated AMD Ryzen 7000 series processors running “Halo: Infinite”. At the same time, AMD CEO Su Zifeng confirmed that the Ryzen 7000 can achieve full-core 5.0GHz and use the new AMD Socket AM5 socket.
According to netizens, AMD Ryzen 7000 series processors are based on the 5nm Zen4 architecture and are scheduled to be launched in the second half of 2022. The new AMD Socket AM5 socket test samples are also in production planning. According to reports, the Ryzen 7000 desktop processor code-named Raphael will be equipped with RDNA2 core display, support DDR5 memory and PCIe 5.0. Before that, AMD also had a Ryzen 75800X 3D with 3D cache on the market.
Today, Apple pushed the iOS/iPadOS 15.3.1 update to iPhone and iPad users. From the official description, the new version clearly informs that it is only to fix vulnerabilities to improve security, and to fix problems that may cause the braille display to stop responding.
According to Apple’s official website security content page, this iOS version fixes a Safari webpage vulnerability, which is “WebKit”. Since processing maliciously crafted web content may lead to arbitrary code execution, this vulnerability has been actively exploited and is likely to be shared publicly, affecting the security of users using the product.
At the same time, the macOS Apple computer system is also affected by this vulnerability, so this time the launch of the macOS 12.2.1 system will also fix this problem simultaneously. Recently, the mobile operating systems of Apple products have been continuously introduced. Many bugs have been fixed to improve security and many new functions have been introduced. It is worth mentioning that Apple has previously pushed the iOS 15.4 beta version to developers, which supports the use of Face ID while wearing a mask. Nowadays, wearing masks has become a part of people’s daily life, and this function can be said to be quite practical. It is reported that when the user chooses to use this function, the system will ask to enter the face ID again, mainly to record the features around the user’s eyes.
Thanks to the cooperation with AMD in mobile GPU, Samsung’s Exynos 2200 flagship chip has received high attention in the industry. However, according to data shared by @TechAltar on Twitter, the Samsung Exynos 2200 has only a 5% increase in CPU speed and a 17% increase in GPU speed compared to the Exynos 2100.
Samsung’s Exynos 2200 flagship chip, GPU is Xclipse 920 based on AMDRDNA2, which is said to support advanced variable refresh rate, ray tracing, etc. Although the NPU performance is doubled, it will not bring better performance. Samsung has not disclosed the energy efficiency/heating index of mobile devices, and in the case of high load usage, the Exynos 2200 chip will be forced to reduce frequency due to overheating, performance Performance will get worse. Previous OpenCL test results showed that the Exynos 2200 easily beat the Snapdragon 8 Gen1, but in the GFXBench test, the Snapdragon 8 Gen1 GPU outperformed the Exynos 2200.
At the previous Samsung Galaxy S22 mobile phone conference, Samsung demonstrated a new feature about Windows 11: the ability to quickly open 3 recent apps on Android devices.
The implementation of this function is based on the newly added “recent applications” in the YourPhone application, which allows users to open the Andriod program on Windows 11, and integrates with the taskbar of the YourPhone application, making it more convenient to open the three recent applications. However, in order to use the YourPhone app, you need to meet the following requirements: A Samsung device running Android 9.0 or higher with a connection to Windows 11. Both devices should be connected to the same Wi-Fi network. YourPhone app v1.21092.145.0 or later. Older versions of YourPhone app do not support recent apps. Connect to Windows 11 version 1.21083.49.0 or higher.
Mobile phone manufacturers have done a very good job in building third-party Android systems, but there are still many die-hard fans who have a soft spot for native Android systems. If you are one of them, you must be familiar with the latest Android 13. On February 11, Google officially released the first Android 13 developer preview. According to the official introduction, this version of the system continues to “make a fuss” around privacy and security. Here are five major upgrade points for you:
First, the system adds a photo selector. Under this function, the application can only access the allowed pictures, not the entire gallery;Then, users can now choose a single color from the theme to adaptively generate style icons;Secondly, the system adds the permission of the adjacent WiFi device, allowing the application to sniff the surrounding WiFi hotspots, but the actual location of the user will not be exposed;Again, the system displays text 200% faster, with almost no sacrifice in rendering performance;Finally, with the boom of folding screen mobile phones, Google specially optimized the folding screen UI for the new system. In the large screen mode, it supports 6 resident applications at the bottom of the main interface.
According to the official introduction, Android 13 will provide developer preview updates from February and beta updates in April. Android 13 Beta 4 will be launched in July, and it is expected that we will see the official version push in October. In terms of adapting models, it is natural that Google’s “pro-son” is the priority. It is reported that Google Pixel 6, Pixel 6 Pro, Pixel 5a 5G, Pixel 5, Pixel 4a 5G, Pixel 4a, Pixel 4 XL and Pixel 4 models can be upgraded to the developer preview. If you have the above equipment, you may wish to try it after updating.
