刚刚监管中心披露最新规定:本月官方发布研究成果通报,探索18和19款MacBook Pro在美国市场的表现与差异

随着科技的发展，笔记本电脑已经成为人们生活中不可或缺的一部分。苹果公司的MacBook Pro系列凭借其出色的性能和优雅的设计，一直深受消费者的喜爱。在美国市场，18款和19款MacBook Pro的表现尤为突出。本文将为您详细解析这两款笔记本电脑在美国市场的表现及它们之间的差异。 首先，让我们来了解一下18款MacBook Pro。这款笔记本电脑于2017年发布，搭载了第八代Intel Core处理器，配备Retina显示屏，支持Touch Bar技术。在美国市场，18款MacBook Pro凭借其出色的性能和轻薄的设计赢得了消费者的青睐。当时，许多专业人士和学生都将其作为日常工作的首选设备。 随着时间的推移，苹果公司于2018年发布了19款MacBook Pro。这款笔记本电脑在外观上与18款保持一致，但在硬件配置上有了显著提升。19款MacBook Pro搭载了更强大的第八代Intel Core处理器和AMD Radeon Pro显卡，同时支持Touch Bar和Touch ID技术。此外，19款MacBook Pro还首次引入了4TB SSD存储选项，使得存储空间更加丰富。 在美国市场，19款MacBook Pro的表现同样出色。由于硬件配置的提升，这款笔记本电脑在处理大型文件和运行复杂软件时更加流畅。同时，19款MacBook Pro的键盘也进行了改进，减少了故障率，提高了用户体验。 尽管19款MacBook Pro在硬件配置上有所提升，但两款笔记本电脑在性能上的差异并非绝对。以下是一些具体的表现和差异： 1. 处理器：19款MacBook Pro搭载的第八代Intel Core处理器在性能上比18款有所提升，但实际使用中的差异并不明显。对于大多数用户来说，18款和19款MacBook Pro在处理器性能上的表现已经足够满足日常需求。 2. 显卡：19款MacBook Pro搭载的AMD Radeon Pro显卡在图形处理能力上有所提升，尤其是在运行专业图形软件时，19款MacBook Pro的表现更加出色。 3. 存储：19款MacBook Pro支持高达4TB的SSD存储选项，而18款MacBook Pro的存储空间最大为2TB。对于需要大量存储空间的专业用户来说，19款MacBook Pro是一个更好的选择。 4. 键盘：19款MacBook Pro的键盘进行了改进，故障率更低，用户体验更佳。 5. 价格：由于硬件配置的提升，19款MacBook Pro的价格相比18款有所上涨。对于预算有限的消费者来说，18款MacBook Pro可能更具性价比。 综上所述，18款和19款MacBook Pro在美国市场的表现都非常出色。两款笔记本电脑在性能、外观和用户体验方面各有千秋。对于消费者来说，选择哪款MacBook Pro主要取决于个人需求和预算。如果您对硬件配置要求较高，且预算充足，19款MacBook Pro无疑是更好的选择。而对于预算有限或对硬件配置要求不高的用户，18款MacBook Pro也是一个不错的选择。

TMTPOST --   Chinese telecommunications giant Huawei unveiled a sweeping expansion of its artificial intelligence computing ambitions on Thursday, announcing new supercomputing systems powered by its in-house Ascend chips. The move signals escalating competition with U.S. chipmaker Nvidia, the global leader in AI processors.AI-generated imageAt its annual Huawei Connect conference in Shanghai, the company introduced the forthcoming "Atlas 950 SuperCluster," which it said will begin rolling out as early as next year. The announcement underscores Huawei ’ s determination to challenge U.S. dominance in advanced AI hardware despite Washington ’ s tightening export controls on semiconductors."The competition has undeniably arrived and is gaining momentum," an Nvidia spokesperson said. "Customers will choose the best technology stack for running the world ’ s most popular commercial applications and open-source models."U.S. restrictions have cut China off from the most advanced chips needed to train large-scale AI models, forcing Chinese firms to rely on domestically developed processors or stockpiles of older foreign components. Huawei, long targeted by U.S. sanctions, has turned to large-scale clustering of its less powerful but increasingly refined Ascend processors. By combining vast numbers of these chips in interconnected networks, the company aims to match or surpass the performance of systems built on Nvidia ’ s hardware.Huawei said it plans to release three new versions of its Ascend chips through 2028, pledging to double computing power with each iteration. At the base level, its new Atlas 950 supernode will connect 8,192 Ascend chips. A full Atlas 950 SuperCluster would integrate more than 500,000 chips.A future upgrade, the Atlas 960 system slated for 2027, is projected to support nearly 15,500 chips per node and scale to more than 1 million Ascend processors across a full supercluster. Huawei claimed these would represent the world ’ s most powerful AI systems by raw computing power.Huawei did not shy away from comparisons with its American rival. Eric Xu, the company ’ s vice chairman and rotating chairman, said the Atlas 950 supernode would deliver 6.7 times more computing power than Nvidia ’ s upcoming NVL144 system. He went further, predicting Huawei would "be ahead on all fronts" compared with Nvidia ’ s 2027 offering — and claimed the Atlas 950 SuperCluster would even exceed the computing capacity of Elon Musk ’ s xAI Colossus project.While independent verification of Huawei ’ s claims is limited, industry experts said the company ’ s ambition is clear."Huawei ’ s announcement on its computing breakthrough is well timed with recent increasing emphasis by the Chinese government on self-reliance on China ’ s own chip technologies," said George Chen, partner and co-chair of the digital practice at The Asia Group. While noting that Huawei might be overstating its technical edge, he added, "the ambition to be a world AI leader cannot be underestimated."Research from SemiAnalysis earlier this year found that Huawei ’ s CloudMatrix system outperformed Nvidia ’ s equivalent despite each Ascend processor offering only about one-third the power of an Nvidia chip. The advantage came from scale: Huawei deployed roughly five times as many chips in its clusters."Computing power has and will continue to be the key for AI," Xu emphasized during his keynote speech in Shanghai.Huawei ’ s new announcements build on earlier efforts. Two years ago, it introduced the Atlas 900 SuperCluster, which it still markets with "thousands" of Ascend chips. On Thursday, the company said it had already deployed more than 300 Atlas 900 A3 supernodes to over 20 clients across telecoms, manufacturing, and other sectors.This momentum reflects a broader push within China to substitute foreign technology with homegrown alternatives. Beijing has increasingly pressed domestic firms to use local suppliers and invest in national semiconductor capabilities. Huawei ’ s breakthroughs are likely to be touted as proof of progress in these efforts.Huawei ’ s offensive comes as Nvidia faces growing headwinds in China, once one of its most important markets. Earlier this week, China extended an antitrust probe into the U.S. company over alleged monopolistic practices. On Wednesday, Nvidia ’ s shares fell more than 2% after the Financial Times reported that Beijing had ordered Chinese tech giants to halt testing and purchases of the RTX Pro 6000D, one of Nvidia ’ s new AI-focused chips.Nvidia Chief Executive Jensen Huang expressed frustration over the developments. "I am disappointed to hear this news," he told reporters, while reiterating that Huawei represents a "formidable" competitor.The geopolitical context adds another layer of complexity. The U.S. and China concluded trade talks in Spain this week that reportedly included discussions over the fate of TikTok, the video app owned by Beijing-based ByteDance. But technology co
