hot_img Changxin Storage's DDR5 yield has exceeded 90%, with varying attitudes among PC manufacturers: Dell has banned it, HP has restricted it to China, while Asus and Acer have already adopted it

According to reports from Fast Technology, Changxin Memory's 17nm DDR5 chip yield has surpassed 90%, which is only about 2 percentage points lower than Samsung's same-generation products at 92% to 93%, marking a technical indicator that has entered the global first tier. Several major PC manufacturers have completed certification for Changxin DRAM chips around mid-year and have begun to incorporate them in small batches into certain laptops.The strategies adopted by different brands show significant differences: Dell has completely banned the use of Changxin chips; HP restricts their use to the mainland China market; Acer and ASUS have incorporated them into models aimed at the mainland China and emerging markets. Currently, the impact of Changxin products on the overall market prices of the three major memory giants remains limited, mainly because Samsung, SK Hynix, and Micron are currently more inclined to supply LPDDR5, while Changxin's current strategic focus is on expanding DDR5 shipments. Executives from PC companies have stated that the three major manufacturers hold over 90% of the global DRAM market share, and large-scale adoption must be approached with high caution. Currently, the number and usage of models using Changxin chips are quite limited.

hot_img Intel's EMIB-T advanced packaging faces yield challenges, with the first mass production target in 2027 only at 50%

According to Taiwanese media reports, Intel's next-generation advanced packaging technology EMIB-T is facing severe yield challenges. ABF substrate supplier Unimicron stated during its earnings call on July 29 that the technology is "not yet mature," and the yield target for three EMIB-T substrate suppliers (Unimicron, Ibiden, and Shinkawa) during the initial mass production phase at the end of 2027 is only 50%.EMIB-T is Intel's advanced packaging solution that competes with TSMC's CoWoS-L, differing in that it embeds the silicon bridge directly into the substrate rather than using a silicon interposer, making substrate suppliers a key factor in determining success or failure. Google's ninth-generation TPU has confirmed that it will adopt EMIB-T packaging when it goes into mass production in 2028, with MediaTek responsible for chip co-design. If the chip successfully goes into mass production, its shipment volume is expected to challenge NVIDIA. Unimicron stated that the customer (Intel) has provided a profit guarantee mechanism, ensuring that suppliers can remain profitable even if yields are poor, and that profit margins will exceed the company's average level after achieving the 50% yield target. Currently, there is still considerable uncertainty about whether EMIB-T can achieve its mass production target by the end of 2027.

Coinbase releases Q2 Solana validator node operation report: 41.63 million SOL staked, with yield and stability exceeding network average

Coinbase released its Solana validator node operation report for the second quarter of 2026, stating that its operated Solana validator nodes outperform the network average in terms of yield, stability, and infrastructure distribution.Data shows that Coinbase currently stakes approximately 41.63 million SOL through 23 validator nodes, accounting for 9.72% of the total staked amount on Solana, with nodes distributed across 7 countries, including the United States, the United Kingdom, Germany, Japan, Singapore, and others.Key operational data is as follows: Staking scale: 41.63 million SOL, accounting for 9.72% of the total staked amount; staking yield: Q2 2026 APY is 6.52%, higher than the network average of 6.38%, leading by 14 basis points; block skip rate: 0.035%, lower than the network average of 0.136%, about one-fourth of the network average.Coinbase stated that its validator nodes adopt a multi-client architecture, currently running 4 clients including Harmonic, Jito, JitoBAM, and Firedancer. All solutions have been reviewed by the Solana Foundation, and aggressive MEV time strategies that may affect user experience are not used.In terms of infrastructure, Coinbase has deployed its validator nodes on two independent bare-metal service providers and configured off-site backups for each node to reduce single points of failure risk. At the same time, the company stated that it has migrated the entire validator node cluster to the DoubleZero network, achieving approximately 99.9% session availability.Coinbase also revealed that it is preparing for the Alpenglow consensus upgrade expected to be advanced by Solana later in 2026, including running community test nodes, developing new consensus health monitoring tools, and completing related voting account upgrade verification.

Changxin's long position funding fee is expected to yield an annualized return of 2130%, with whales able to net a profit of 740,000 USD in a single day

According to monitoring by Hyperinsight, the current hourly funding rate for Changxin has dropped to -0.2430%. A negative rate means that shorts pay longs; based on the current rate, the simple annualized return is approximately 2129%.Calculating with a position of $10,000, shorts need to pay about $24.3 per hour, while longs receive an equivalent income; if the rate is maintained for 24 hours, the corresponding funding fee is about $583.3.The largest long position starting with 0x9a8 is the main beneficiary of this round of negative rates. Records show that since the morning of July 15, it has completed 183 funding fee settlements for CXMT, with a cumulative net income of about $991,400, achieving a return rate of about 45.9% on the initial capital.This whale currently holds a leveraged long position of 1,633,200 CXMT at 5 times, with a position value of about $12,742,000 and an average entry price of $6.6156. CXMT is currently priced at $7.80, with an unrealized profit of about $1,938,000 (89.7%), and the liquidation price is only $0.507.Based on the current position and a static rate of -0.2430%, this whale can earn about $31,000 in funding fees in the next hour; if maintained for 24 hours, this corresponds to about $743,000.This whale currently still has 7 buy orders not labeled as "only reducing positions" between $6.01 and $6.41, planning to continue buying 98,000 CXMT, with a nominal amount of about $609,000, and has not chosen to cash out the existing long position.
