Tech giants form a new alliance to push Matter's new standard for smart home connectivity

 A new alliance formed by large technology companies such as Apple, Amazon, and Google has just announced a connection standard called "Matter", which aims to improve the security and interoperability of smart home devices. MacRumors pointed out that Matter was originally called "Project CHIP", which is an IP-based dedicated protocol for building and connecting IoT ecosystems. Thanks to the royalty-free policy, it can encourage various IoT device manufacturers to work together safely and ensure the reliability of projects built on this standard.

For consumers who have deployed a large number of IoT devices at home, the new world led by Matter will allow them to fully enjoy the benefits of smart door locks, thermostats, smart speakers and other devices.

In addition to easily adding new devices that support the Matter mark to the home network, related companies can also rely on a unified network to keep the company's business running smoothly.

It is worth mentioning that Matter can also ensure that smart home devices are compatible with smart home/voice services such as Amazon Alexa, Apple HomeKit, Google Assistant, and Samsung SmartThings.

The first implementation of the Matter specification has been able to run on existing network technologies (such as Ethernet, Wi-Fi, Thread, and Bluetooth Low Energy).

AMD’s overall CPU market share declined last quarter, But server processors ushered in the biggest increase in 2006

 Although Intel has been launching new processors since the first quarter of this year, AMD's Zen 3 architecture series processors are still very capable and can be said to have their own advantages in performance. However, the impact of the shortage of the global semiconductor industry chain is obviously greater than that of Intel. AMD’s desktop processor market share in the first quarter of this year remained the same as last quarter, and the notebook processor’s market share fell by 1%. But in the server field, AMD has set the biggest increase since 2006.

Mercury Research released a report on the CPU market share in 2021. AMD processor price trends this quarter were exceptionally strong, as shipments of low-end products decreased, shipments of high-end products increased, and shipments of server processors also increased. Increase, the average selling price of AMD processors in the quarter has increased substantially. This is caused by shortages in the supply chain. AMD has prioritized the production of its high-end desktop processors and server processors due to limited production capacity, and shipments are the second highest in history, an increase of 41% year-on-year.

Of course, compared with Intel, which has its own fab, AMD is more affected by the shortage. The desktop processor has terminated its decline in the previous quarter, and its market share remained at 19.3% this quarter, which was the same as the previous quarter. Intel’s Rocket Lake processor does have a significant improvement in IPC. Compared with the previous Comet Lake, it is indeed a greater threat to AMD. The number of high-end cores is still at a disadvantage, but AMD’s own Ryzen 5000 is still in the low-end. The series APU has not yet been supplied to the market in large quantities, and the impact here is estimated to be reflected in the next quarter.

In the mobile market, because AMD prioritizes the higher-priced Ryzen 7/5 and other models, although shipments and revenue are record-breaking, this does not prevent AMD’s mobile market share from falling, because Intel supplies Relatively complete, even low-end Celeron processor shipments are increasing, so AMD's market share dropped from 19% in the previous quarter to 18%, which has been falling for two consecutive quarters.

AMD’s EPYC Milan and Intel’s Ice Lake-SP were officially released last quarter, but server processors usually have a lot of shipments to customers before they are released. After all, server vendors need time to test and debug. . It is obvious that AMD EPYC Milan has succeeded. Its market share has risen from 7.1% in the previous quarter to 8.9%, an increase of 3.8 percentage points compared with the same period last year. In contrast, Intel’s data center revenue plummeted in the first quarter of this year, down 20% year-on-year, and shipments down 13%. Although Intel said customers were digesting inventory, the inventory was clearly AMD’s.

On the whole, AMD lost 1 percentage point in the entire x86 CPU market share last quarter, dropping to 20.7%. The supply chain shortage has a considerable impact on AMD, forcing them to prioritize the shipment of high-end chips. Can ensure profit. On Intel's side, they used their own capacity advantages to expand their share, but this was mainly won by the low-end market, at the expense of profits.

Airbus: C919 will become a strong competitor of A320neo

 Civil Aviation Resource Network, May 8, 2021: Airbus CEO Guillaume Faury stated at the Atlantic Council EU-U.S. Future Forum on May 6 that at the end of 2020-2030, COMAC C919 will become A strong competitor of Airbus A320neo. He believes that C919 has the ability to gradually transform the single-aisle passenger aircraft market into a three-pronged situation of Boeing, Airbus and COMAC.

　　 For a long time, the commercial aircraft manufacturing industry has been monopolized by Airbus and Boeing. However, Faury believes that COMAC has made rapid progress in recent years and this situation will change. "It will start slowly. At the beginning, it may only involve Chinese airlines, but we believe that it will gradually become a good participant. At the end of this decade, in terms of a single-channel market, we may change from a duopoly. To become a three-legged camp."

　　 So far, C919 has received more than 800 orders, almost all from Chinese airlines and leasing companies. Although China's domestic aviation market is vast, this alone is not enough to make the C919 successful. Faury believes that C919 will start strongly in China, and then it will go global. "We believe that C919 will start in China, because Chinese airlines are state-owned enterprises, so it is easier to do so. It takes a lot of time to prove the maturity of the product to make it reliable, credible and economically viable. But we believe that, In the field of single-aisle aircraft, COMAC will gain a certain market share by the end of this decade."

　　 Interestingly, Ryanair expressed strong interest in the early development of C919. In 2011, Ryanair and COMAC signed a memorandum of understanding at the Paris Air Show. The CEO of Ryanair reiterated its commitment to the C919 project last year, saying that the competition between COMAC and Airbus and Boeing will benefit the development of the aviation industry.

　　 China has always been an important market for Airbus. Last year, about 20% of Airbus's aircraft were delivered to Chinese customers. Faury said that the Chinese market will "gradually introduce domestic products", which will weaken Airbus's interests in the region.

Samsung will launch Exynos SoC with AMD GPU in the second half of the year. Applicable to both laptops and mobile phones

 Samsung will launch Exynos SoC equipped with AMD GPU in the second half of the year, which can be applied to both laptops and mobile phones

There was news in the first two months that Samsung was preparing to launch a new Exynos SoC, including a CPU based on the ARM architecture and a GPU based on AMD graphics technology. Samsung will carry out targeted customization. The first product to be carried is likely to be a thin and light notebook computer. Its positioning is similar to the SC8280 being tested by Qualcomm, which is the successor of the 8cx Gen 2 SoC.

According to the "Korea Economic Daily" report, Samsung will launch this SoC in the second half of the year, possibly as early as June, and will be manufactured using a 5nm process. According to sources, this product will have very good computing power, and it will also bring excellent battery efficiency to the device, not only for laptops, but also for smart phones.

According to this statement, it is estimated that the first batch of platforms will eventually be mounted. Although Samsung’s speech at the Exynos 2100 conference at the beginning of the year made people focus on Samsung’s flagship smartphones, the subsequent news pointed to thin and light laptops, which vacillated between the two.

It is understood that this situation occurs, to a certain extent, because Samsung hopes that this product will be positioned similar to Apple's A14 Bionic, and will adjust the original Exynos SoC development plan. If you want to achieve certain performance indicators, it may affect heat dissipation and power consumption. Samsung needs to consider how to balance performance and power consumption to adapt to different platform carriers. I believe that it will work hard for this in the next few months.

Many people are very interested in Samsung's Exynos SoC using AMD's custom GPU. They want to know the performance, specifications and technology of its GPU, and hope that Samsung can let everyone see its true colors as soon as possible.

Which Sony, Canon, Nikon focus is better?

 I remember that when I bought the Sony A7R2 a few years ago, many people said that Sony's focus was not good. At that time, N, C had not produced full-frame mirrorless. Now in the mirrorless era, how do you feel that the Nikon focus is the weakest? Has Sony improved so much in recent years? Is it much better than Nikon Canon? I have been considering whether to buy Nikon or Sony the next one. The focus is mainly on focusing. If the image quality is not evaluated, it should not be much worse. If the R5 is not a rotating screen, it is estimated that Canon may be considered, but this rotating screen feels that the reliability is lowered. It was only done in low-end machines before, so Canon is not considered for the time being.
