Since the launch of the Samsung S22 Ultra, the crown of the new generation of Android phones has fallen on this flagship product. But to the great disappointment of Android users, despite the blessing of the new Snapdragon 8 processor, in terms of running points alone, there is still a big gap from the A15.

Tested by well-known IT magazines, the Galaxy S22 Ultra, powered by the new Snapdragon 8 processor, scored 1232 in single-core and 3433 in multi-core, while the corresponding iPhone 13 Pro Max single-core and dual-core are 1735 and 4647 respectively. In the multi-core part, Apple is at least 35% faster.
In the GeekbenchML (machine learning) test session, the iPhone 13 Pro Max equipped with A15Bionic achieved 948 points, while the corresponding Samsung achieved only 448 points.
Of course, for mobile devices, it is not objective enough to judge the performance of a mobile phone simply by running points. What’s more, Samsung’s advantages in screen, camera, operating system, etc. cannot be reflected simply by running points.

According to media reports, the United States is now turning to Russia after years of restricting China, but the reasons are very different. It is reported that since many raw materials for domestic semiconductor production in the United States come from Russia and Ukraine, including elements such as neon gas and palladium, 35% of the palladium in the supply of palladium comes from Russia. More than 90% of palladium comes from Ukraine. The US is urging relevant companies to find alternative sources of purchases as soon as possible to reduce imports from relevant countries.

Peter Harrell, a member of the White House National Security Council, and his staff have been in contact with people related to U.S. chip companies in recent days, but they have refused to disclose relevant details, only saying that the U.S. government is ready for Russia to “invade” Ukraine. “Part of that is working with companies to ensure they are prepared for a supply chain disruption should Russia take action to disrupt supply chains,” the senior official said. “We understand that other sources of these critical products are available and are ready to work with us. (U.S.) companies working together to help them secure and diversify supply.”
It can be seen that the United States is very concerned about the tense relations between Russia and Ukraine, and has the attitude of adding fuel to the fire. The U.S. government has also threatened to impose sweeping export controls on Russia if Russia “invades” Ukraine. Some U.S. politicians have also taken the lead in drafting sanctions against Russia, and the proposed sanctions include Russian President Vladimir Putin.
However, the Russian side has always said that the so-called “invasion” is “baseless” and stressed that the United States and other Western countries have been creating tensions. Ukrainian President Volodymyr Zelensky also expressed his strong dissatisfaction with this. It is very unwise to spread rumors about the relationship between Russia and Ukraine. Russian Presidential Press Secretary Dmitry Peskov said in January that considering that Russia will inevitably respond appropriately to U.S. sanctions, proposing new U.S. sanctions against Russia can be tantamount to proposing to sever ties.

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.
