first_img Musk: After China masters the technology, its production capacity may exceed the sum of other regions in the world

On October 13, Tesla CEO Elon Musk stated on social media platform X: Once China masters the manufacturing methods for a certain type of product, its ability to scale production often exceeds that of the rest of the world combined. He cited lithium batteries and solar energy as examples, claiming that China has demonstrated this characteristic in these fields. This statement was in response to a discussion about memory manufacturer Changxin Storage.The poster Melvin believes that Changxin is already a competitor that cannot be ignored, but whether new technology can stably achieve large-scale mass production still depends on yield, cost, and reliability. He also noted that memory demand is still growing, and an increase in production capacity does not mean that the market will immediately experience oversupply. Regarding memory, Musk mentioned that about three years ago, memory was still a low-margin commodity, with LPDDR5 and LPDDR6 designed according to common standards, and China seems to be rapidly solving related technical issues.Musk also pointed out that the new generation of high-bandwidth memory architecture is more difficult to tackle. Another challenge is placing a layer of SRAM beneath the logic chip and stacking RAM in three dimensions above it while addressing the heat dissipation issues of the logic chip. Phoenix Technology cited public information stating that on September 7, Changxin Storage announced that LPDDR6 has entered mass production and was first commercially used in the Xiaomi 18 Fold, with a capacity of 16 GB, compliant with JEDEC's LPDDR6 standard. Subsequently, Changxin announced that its fifth-generation DRAM process platform has achieved mass production and launched two LPDDR5X products based on this platform, aimed at smartphones and portable consumer electronics, with a single bare chip capacity increased by 50% compared to the previous generation of similar products.

first_img Doubao adds life payment services, allowing users to initiate payments for water, electricity, and gas

According to the WeChat public account "Du Jia," ByteDance's AI assistant Doubao has added a utility payment feature. Users can initiate payment instructions for water, electricity, gas, and other services through voice or text in the Doubao app, with other life service scenarios also in development. Sources close to Doubao told "Du Jia" that Doubao is gradually building capabilities for handling tasks in life scenarios, including travel services and utility payments."Du Jia" claims to have tested that after issuing commands for paying electricity and water bills in the dialogue box, corresponding service cards pop up and redirect to the utility payment page. The interface is divided into electricity, water, and gas fees, with some regions showing that services are not yet available, while some cities have fully or partially opened them. The relevant framework has been established, and city coverage and service provider integration are still in progress, with actual payments requiring further permission to be granted.Currently, the dialogue only serves to invoke services; steps such as binding account numbers, confirmation, and payment will still be retained, and users will not be charged directly with a single command. Alibaba's Tongyi Qianwen integrated utility payments earlier and can complete payments within the dialogue; Doubao at this stage redirects to handle tasks after invoking the card, and capabilities like food delivery have not yet been launched. The above content comes from "Du Jia" reports and tests, not an official announcement from Doubao.

SemiAnalysis: ByteDance accounts for nearly one-fifth of China's data center capacity

The semiconductor research organization SemiAnalysis released a survey on Chinese data centers, tracking over 1,000 facilities from more than 60 operators. The report estimates that by the end of 2026, China's data center capacity will exceed 24GW, second only to the United States' 56GW. ByteDance accounts for nearly one-fifth of this, making it the largest data center tenant in the country.ByteDance has leased over 4GW of data center capacity, with suppliers including Qinhuai Data, China United Network Communications, and Century Internet. The report states that by early 2026, ByteDance will still contribute about 90% of Qinhuai Data's revenue. ByteDance has also begun to accelerate its self-built data centers, constructing large facilities in Shanxi, Anhui, and Inner Mongolia to reduce reliance on external suppliers.The report also mentions that while Chinese data centers have long been considered to have a high vacancy rate, AI server rooms are still in short supply. This is due to many old server rooms lacking sufficient power supply and cooling capabilities, making it difficult to directly deploy high-power AI servers, while newly built large AI data centers are quickly being rented out. For example, a 100MW data center, excluding IT equipment such as servers, has a construction cost of about $300 million in China and about $1.5 billion in the United States, with Chinese facilities of the same scale typically delivered in about 12 months. Compared to the power supply and approval issues faced by the United States, the more prominent bottleneck for expanding AI data centers in China is the supply of advanced chips.

first_img Samsung Electronics executive: It is expected that HBM will account for nearly 30% of DRAM wafer production capacity next year

According to a report by the Financial Associated Press citing local media on September 29, Samsung Electronics Executive Vice President Kim Taewoo stated that HBM is expected to account for nearly 30% of the total wafer capacity of DRAM manufacturers next year, up from the current ratio of about 20%. He mentioned that HBM competes with traditional DRAM for the same batch of wafer capacity, and increasing HBM output may squeeze the supply of traditional DRAM.TrendForce previously predicted that by the end of 2027, the HBM wafer input from the three major global HBM suppliers will account for about 30% of the total DRAM wafer input, but in terms of storage capacity, it will only contribute about 13% of the total DRAM supply. Additionally, according to media reports on September 20, Samsung began mass production and shipment of HBM4 in February this year and provided 12-layer HBM4E samples to customers including NVIDIA in May; the industry expects Samsung's monthly wafer input for HBM to increase from about 180,000 wafers this year to about 250,000 wafers next year.On the same day, TrendForce stated that the demand for AI servers continues, and HBM and general DRAM will still share limited advanced process capacity. The storage supply will remain tight in 2027, and the price expectations for HBM in 2027 have been raised, with an expected year-on-year increase of 121% in the mixed average selling price. Due to limited supply and rising system costs, 8-layer HBM is expected to become a priority evaluation option for several manufacturers in 2027, with its price per Gb expected to be about 10% to 20% higher than that of 12-layer products.

first_img Major manufacturers increase orders, TSMC's 2-nanometer monthly production capacity is expected to reach 120,000 wafers by the end of the year

According to the Economic Daily, major companies such as Apple, NVIDIA, AMD, Qualcomm, and MediaTek are racing towards AI and high-performance computing, recently increasing their orders for TSMC's 2-nanometer family capacity by 10% to 20%. As a result, TSMC is accelerating the expansion of its 2-nanometer family, with progress exceeding expectations. TSMC has consistently refrained from commenting on customer information and market rumors.The market originally estimated that TSMC's monthly capacity for the 2-nanometer family would be around 90,000 to 100,000 wafers by the end of this year, with expectations for continued double-digit growth to reach 110,000 to 140,000 wafers by 2027. Industry sources indicate that due to strong customer demand, the monthly capacity is expected to surge to 120,000 wafers by the end of this year, achieving the originally set 2027 target ahead of schedule. Sources say that in response to the demands from Apple and non-Apple customers, the speed and scale of new capacity for the 2-nanometer family are setting new records, far exceeding the ramp-up speed of the 3-nanometer family in its first year.TSMC's Senior Vice President and Co-COO, Wei Chen-Hao, stated at this year's North America Technology Forum that in response to strong demand from AI and other sectors, there will be five 2-nanometer fabs ramping up simultaneously for the first time this year, including two in Hsinchu and three in Kaohsiung; the wafer output in the first year of 2-nanometer will increase by 45% compared to the first year of 3-nanometer in 2023; the compound annual growth rate of 2-nanometer capacity from 2026 to 2028 will reach 70%. TSMC's 3-nanometer capacity in the Southern Taiwan Science Park is expected to reach nearly 180,000 wafers per month in the fourth quarter of this year, and three new 3-nanometer fabs are being established in Taiwan, Arizona in the United States, and Japan. The second fab in the United States is planned to begin mass production in the second half of 2027.

first_img Solana block speed increased by 17%, transaction capacity remains unchanged

On Friday, Solana shortened the target slot time from 300 milliseconds to 250 milliseconds, increasing the network clock speed by nearly 17%. A slot is a short window designated for validators to add blocks. After the adjustment, Solana aims to produce about 4 blocks per second, up from about 3.3 blocks previously, allowing wallets, exchanges, and trading applications to obtain a more real-time network status.Validators will still lead for 4 consecutive slots, so each leader's control window has been reduced from 1.2 seconds to 1 second, and the transaction ordering rights will be handed over to the next validator earlier. For applications such as oracle-driven markets and automated market makers, stale prices or hundreds of milliseconds of uncertainty can affect trade execution, and a faster clock is expected to reduce failed transactions and price deviations. However, the speed increase did not result in a 17% increase in original capacity; according to SIMD-0525, the allowed computation and data volume per slot has decreased by the same proportion, and the overall processing limit of the network remains basically unchanged.This adjustment is the third phase of Solana's gradual reduction from 400 milliseconds to 350 and then to 300 milliseconds. Since the epoch is still fixed at 432,000 slots, its expected duration has decreased from about 36 hours to about 30 hours, leaving less time for offline signing and delayed approvals. There is currently no timeline for the proposed further reduction to 200 milliseconds to go live on the mainnet, and the network will advance only if the block skip rate remains acceptable at the 250 milliseconds stage.
