MacOS Monterey is the latest version of MacOS and will be available on MacBook, iMac, and Mac Mini soon. Recently, Apple has just confirmed that MacOS Monterey will support Adaptive Sync on external displays. This feature allows a lot of new Macs to support variable screen refresh rates, somewhat satisfying gamers. Macs that will receive Adaptive Sync support include versions running the M1 chip, as well as some new Intel-powered Macs to be announced later. Of course, the monitor must also support Adaptive Sync, a feature of the VESA DisplayPort 1.2a standard as the technology is also used by both Nvidia’s G-Sync and AMD’s FreeSync. The displays on the iMac and MacBook are fixed-ratio displays, so neither of them support this feature. Apple claims that enabling the feature will be very easy to do. After connecting a compatible Adaptive Sync display to a Mac, all the user has to do is select the refresh rate in System Preferences > Displays. Adaptive Sync is a technology that eliminates screen tearing, stuttering, and input lag. It synchronizes the screen refresh rate with the frames per second (fps) provided by the graphics card. The result is a smoother gaming experience as the display adapts to what’s happening in the game. Although, Mac computers are often not the first choice when it comes to gaming computers, they are often preferred by content creators. But who knows, the addition of Adaptive Sync suggests that Apple may be looking to expand its reach to a whole new set of customers. The arrival of Adaptive Sync support could suggest that Apple plans to bring higher refresh rate displays to Macs in the future. MacOS Monterey is currently in beta and is open to developers only. Apple plans to open public beta testing in July, allowing some users to start using Adaptive Sync soon. If everything goes according to schedule, MacOS Monterey will be released on all compatible devices in the fall.

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.

To deal with AMD, the 11th generation Intel H-series mobile processors are manufactured on the 10nm process, support up to 8 cores and 16 threads, support video memory direct connection technology and PCIe 4.0 technology with “5GHz high frequency”. Power consumption of Intel’s H45 processor is divided into 2 levels, OEM manufacturers can choose 35W or 45W version depending on needs. All systems are equipped with 32cu Xe cores as standard and the operating frequency is 1450MHz. The H45 product sequence and general specifications are as follows: i9-11980HK: 8 cores 16 threads, 2.6GHz base frequency, 2 cores / 4 cores / all-core boost frequency 5GHz / 4.9GHz / 4.5GHz, 24MB L3 cache; i9-11900H: 8 cores 16 threads, base frequency 2.5GHz, 2 cores / 4 cores / all cores Boost frequency 4.9GHz / 4.8GHz / 4.4GHz, 24MB L3 cache; i7-11800H: 8 cores 16 threads, base frequency 2.3GHz, 2 cores / 4 cores / full core Boost frequency 4.6GHz / 4.5GHz / 4.2GHz, 24MB L3 cache; i5-11400H: 6 cores 12 threads, base frequency 2.7GHz, 2 cores / 4 cores / all core Boost frequency 4.5GHz / 4.3GHz / 4.1GHz, 12MB L3 cache; i5-11260H: 6 cores 12 threads, base frequency 2.6GHz, 2 cores / 4 cores / all cores Boost frequency 4.4GHz / 4.2GHz / 4GHz, 12MB L3 cache. The H45 series processors have 20 PCIe 4.0 channels, integrated Thunderbolt 4 technology, and support for the Intel Killer Wi-Fi 6E wireless network card. It also has dual eDP outputs to optimize power consumption. The former direct connect technology of processor video memory is also present on the H45 series, allowing the processor to access all data in the onboard video memory at once. In addition, the memory frequency support of the H45 processor reaches 3200MHz. The most advanced version, 11980HK is a version that can be overclocked freely. You can customize how often it works using the Intel XTU software. Intel says the H45 series processors support the latest third-party discrete graphics, supporting either FHD 360Hz displays or 4K 120Hz displays. The single-core performance of the new generation of Tiger Lake-H processors can be up to 19% higher than the performance of Comet Lake-H. This is the most powerful processor for laptops. When compared to AMD, Intel claims that the gaming performance of laptops equipped with the new H45 is 20% higher on average than AMD when all systems “maximize performance”. Ingel says there are already more than 80 high-performance laptops that will use the H45 series processors. Intel also shipped 1 million H45 series processors to OEMs during the launch. Most laptops equipped with the H45 series will be revealed soon. According to Zaeke

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.
