There are only a few major events in the hardware industry in June every year. After all, Apple WWDC supports the appearance. At the same time, many manufacturers’ new products and new product previews will be released at this mid-year node. In addition to Apple, the brands involved include Microsoft , Intel , Xiaomi , Lenovo and so on. In addition to new products, there are also some tips worth learning. For example, a few lines of code Zen processor performance increased by 40%.
01 Domestic chip manufacturers’ new chip technology bypasses EUV lithography machines
There is no doubt that the biggest obstacle facing domestic chip manufacturers today is EUV lithography machines. However, EUV lithography machines are a way to develop advanced chips, but they are not the only solution.
For domestic manufacturers, in the current development of 3D NAND flash memory, they have found opportunities to catch up with technology because they do not need EUV machines. In the field of DRAM memory chips, although the answers found by Samsung, Micron, SK Hynix are EUV, Xinmeng from Zhejiang Haining has developed a new solution to bypass EUV lithography.
Xinmeng Technology CEO Hong Feng announced the launch of the 3D 4F2 DRAM architecture based on HITOC technology. He pointed out that the biggest feature of the new architecture 3D 4F2 DRAM chip developed based on HITOC technology is that it does not require an EUV lithography machine or multiple pattern exposure SAQP (Self-Aligned Quadruple Patterning) steps, which can significantly reduce costs. More importantly, it avoids equipment being stuck by foreign manufacturers.
The so-called HITOC, the abbreviation of Heterogeneous Integration Technology on Chip, is to use advanced wafer pair of wafer and die to wafer hybrid bonding manufacturing process to align different types of wafers or die up and down. , to achieve true three-dimensional heterogeneous single-chip integration.
02 Engineer's few lines of code increased the performance of Zen processors by 40%
This month, AMD engineers submitted a few lines of code to solve the kernel scheduling problem, which can increase the performance of AMD's Zen processors by more than 40%. However, intel's Xeon Qiang also benefited, and the improvement was even higher.
Judging from the explanation provided by Linux, the kernel scheduling before Linux has problems with the NUMA nodes of multi-socket processors. During allocation, it is easy to concentrate some CPU tasks, but some CPUs will be idle, resulting in insufficient utilization.
Some code he submitted fixed this problem. It can check whether the number of CPUs allowed in the local organization is less than the number of running tasks to avoid CPU accumulation. Judging from actual testing, these lines of code have a huge effect. The memory benchmark performance in the Stream task has been improved by 36-44%.
03 Win11 22H2 official version ISO is free to download
This month, Microsoft pushed 22H2 (Build 22621) to Insider members of the Release Preview channel. Unless there are major errors, it will soon reach the official version channel, which is the ordinary version. Non-member users.
For genuine users, the security update support for the first official version of Win11 (Build 22000) is only until October 2023. Therefore, if there is no special reason, it is recommended to iterate to 22H2 as soon as possible after the Update is turned on.
However, Microsoft emphasized that the 22H2 update needs to meet the minimum hardware requirements of Win11, otherwise it cannot be upgraded. This means that older computers that previously used PE or tools to bypass TPM 2.0 and CPU limitations may have to use clean installation again.
It is generally believed that the official version of 22H2 will be released in September or October. Unfortunately, there is no news or action about Win10 22H2 so far. Microsoft really doesn’t care at all.
04 Intel 13th generation CPU series exposed
Intel’s 13th generation CPU currently has new news. The new architecture has been upgraded from 8 performance cores + 8 performance cores to 8 performance cores + 16 performance cores, for a total of 24 cores and 32 threads. It will also be equipped with an LGA1700 platform motherboard, which means that the 13th and 12th generations of pins are basically compatible, and can support both DDR4 and DDR5 memory.
html The 113th generation Core has now been revealed to have an additional module. The SSD interface has a new AI M.2 module, which is probably to further enhance the AI acceleration capabilities of the 13th generation Core.
Judging from the current performance situation, the 13th generation Core flagship i9-13900K GeeKBench 5 single-core score can exceed 2300 points, and the i9-12900K is basically around 2000 points.
05 Domestic operating system released: mobile phones and computer applications are compatible with
Recently Deepin officially announced that the domestic operating system deepin 20.6 version is officially online. The new version has upgraded the Stable kernel to 5.15.34, providing a better user experience and more practical applications. . The new version of the operating system

In addition, the system has also optimized the file manager, calendar, installer and other functions, and fixed some bugs. If you are interested, you can go to Deepin Technology official website to download the system and experience .
06 Xiaomi releases 2-in-1 notebook
This month, Xiaomi released a 2-in-1 notebook Xiaomi Book S 12.4 overseas. The price of tablet + keyboard cover is 799 euros (approximately RMB 5616.97).
It is understood that Xiaomi Book S 12.4 is equipped with Qualcomm Snapdragon 8cx Gen2 processor, 8+256G storage space, supports micro SD card slot expansion to 512GB, has a USB-C interface and a 3.5 audio interface; uses a 12.4-inch IPS LCD panel, 2560 x 1600 resolution, 100% DCI-P3 color gamut, supports touch.
Xiaomi Book S 12.4 has a built-in 38.08 Wh/4,920 mAh battery and supports 65W fast charging. In addition, it also carries the Windows 11 version based on ARM.
07 RTX3080 top independent graphics card actually only costs 2800
Tom's Hareware recently calculated the price trend of graphics cards in the US market. There are not only new cards, but also second-hand cards. New card prices come from retail market statistics. From June 1st to June 15th, the average price reduction for half a month was 2%. Among them, RTX 3070Ti and RTX 3070 both dropped by 7%. The newly released RTX3080 12GB increased by 9% due to shortage. He is also the only one who bucked the trend. The second-hand price of
comes from eBay. It has dropped by as much as 10% on average in half a month. RTX 3070 and RX 6950 XT are both as high as about 20%. However, RX 6750 XT and RX 6400 are much more expensive.
Interestingly, similar to China, there are also many "mining owners" in the United States who are selling mining cards and in packages. For example, someone sells six RTX 3080s for US$2,500, which averages out to only 2,800 yuan per unit.
Although it is so cheap, do you dare to take over in front of the screen?
08 Windows 10 big update is coming
Although for Microsoft, the main goal now is to increase the number of Windows 11 users, they also need to maintain Windows 10. A recent optional update for Windows 10 confirmed the upcoming 22H2 feature update.
It’s worth noting that force-enabling Windows 10 22H2 won’t get you any new features. In fact, Windows 10 22H2 may not bring any consumer-facing capabilities at all. Microsoft will most likely release it as a small enablement package, like several previous "feature updates."
For the average consumer, it makes no sense to enable the next update before Microsoft officially releases it. This just confirms that Microsoft still cares about Windows 10, even though all the good stuff is now exclusive to Windows 11.
For Microsoft, Windows 10 will continue to be supported until 2025, which means users can expect more "feature updates" to arrive in the coming years.
09 Microsoft admits that Win11 has a "bizarre" Bug
This month, Microsoft reported that the KB5014697 cumulative update it released will cause problems with Wi-Fi hotspots, causing the system to automatically disconnect from the network when the device is connected to Wi-Fi.
Currently, this bug has affected systems from Win7 to Win11, and the only way to bypass this vulnerability is to turn off the Wi-Fi hotspot and use other methods to connect to the network.
It is worth mentioning that in addition to the clients from Win7 to Win11 being affected by the bug, Windows server systems are also affected, which may affect servers using Microsoft systems.
As of now, Microsoft has not yet provided an update patch for this problem.
