AMD's game-changing Strix Halo APU, formally known as the Ryzen AI Max+, poses for new die shots and gets annotated AMD's Strix Halo, powered by Ryzen AI Max, has been unveiled with detailed die shots revealing its advanced engineering. The chip features 16 cores/32 threads based on Zen 5 architecture and a 40 CU iGPU developed using RDNA 3.5. It includes two modified Zen 5 CCDs supporting 3D V-Cache and a large I/O die with an XDNA 2 NPU offering 50 TOPS AI performance. The design also incorporates LPDDR5X memory across a wide interface to address potential bottlenecks, along with advanced multimedia support features. Initial laptops搭载Strix Halo预计本月晚些时候上市，Asus的ROG Flow Z13将于2月25日发布。尽管初期采用率可能缓慢，但随着OEM厂商逐渐接受，未来应用有望增加。 请注意，最后部分出现了一个翻译错误，我将纠正并保持内容为英文摘要： The first laptops powered by Strix Halo are expected to hit shelves later this month, with Asus' ROG Flow Z13 scheduled for a February 25 release. While OEMs have been initially hesitant about adopting these chips, adoption is likely to increase over time despite a slow initial uptake. (Image credit: Tony Yu) AMD's Strix Halo reviews are no longer guarded by an embargo . So we're seeing a wave of new die shots that underline the impressive engineering that went into the design of these chips. Thanks to Kurnal, Asus' Tony Yu (at Bilibili ), and Decap at X (formerly Twitter), we're getting our first look at the internals of Strix Halo, formally known as Ryzen AI Max. Let's get one thing straight: Strix Halo isn't your average run-of-the-mill APU. It wields 16 cores and 32 threads based on the latest Zen 5 architecture, alongside a massive 40 CU (Compute Unit) iGPU (integrated GPU). The package itself is composed of two Zen 5 CCDs, which are a tad different from the ones you see on Granite Ridge (Ryzen 9000 CPUs). Surrounding the chip are up to eight memory ICs, enabling support for 128GB of unified memory. Thanks to high-res images from Tony Yu, we see that AMD has trimmed the D2D (Die to Die) interfaces between the CCD and I/O die by roughly 2mm. Although the CCDs have been tweaked slightly at 67.07mm 2 , they still support 3D V-Cache, evidenced by the TSV connections in the die shots. The rest is similar to what you'd typically find on a desktop Zen 5 processor. Each of the eight cores carries 8MB of dedicated L2 cache, with a shared 32MB L3 pool in between. Beneath the two CCDs lies a large I/O die that hosts the uncore part of the chip. The bulk of the 307.58mm 2 die size is occupied by the 40 Compute Unit integrated GPU (20 WGPs) developed using RDNA 3.5. Slapping on more cores is only beneficial if they can be fed with data. We've seen firsthand how the performance of Strix Point (with 16 CUs) was hampered due to memory bottlenecks. AMD has taken a two-pronged solution to counteract this issue, with fast LPDDR5X memory across a wide 256-bit interface (eight 32-bit controllers) to the sides of the chip, and 32MB of MALL (Memory Access at Last Level) or LLC (Last Level Cache) split evenly across both sides of the iGPU. Image 1 of 5 (Image credit: Tony Yu) To the left of the iGPU lies the XDNA 2 NPU (Neural Processing Unit), enabling 50 TOPS of AI performance, claimed to outclass even the RTX 4090. Some locations have been left unmarked. Either way, the bottom of the I/O die features a single PCIe 4.0 x16 interface, alongside USB 4 (40 Gbps), USB 3.2 Gen 2, and USB 2.0 controllers, followed by a Display Engine and two Media Engines with support for H.264, H.265, and AV1 codecs. Based on the provided statistics, the full chip equals roughly 441.72mm 2 or allegedly 475mm 2 . That's including what appears to be structural silicon. The first laptops powered by Strix Halo should hit shelves later this month, with Asus' ROG Flow Z13 tipped for a February 25 launch. While OEMs have initially been hesitant to jump on board with these chips, adoption is likely to improve, despite a slow initial uptake.

Palantir今天跳了 - 热热的人工智能（AI）股票仍然是购买吗？

众议员Marjorie Taylor Greene在公司购买了新股后，Palantir的股票在周二上涨了4.6％。Palantir的市值已达到约2840亿美元，估值约为今年的预期收益和预期销售的75倍。尽管由于其高增长依赖性估值，但鉴于该公司的可扩展业务模式并领导了针对私营和政府部门的AI软件产品，但长期投资者的风险很高。但是，应谨慎对待投资以美元成本的策略进行。palantir

AI Services电信公司的魔术收入子弹是吗？

电信公司正在探索AI作为传统5G货币化之外的新收入来源。NVIDIA的克里斯·彭罗斯（Chris Penrose）概述了三个主要机会：提供gpus-as-a-service，提供数据策展和模型培训等平台服务，并进入诸如客户体验平台之类的应用程序服务。电信公司旨在利用电信行业的基础设施和专业知识来吸引企业客户和政府合作伙伴寻求AI能力。像AMDOC这样的公司正在开发工具，以促进电信公司进入AI驱动的收入流，并期望具有巨大的增长潜力。

法庭文件中的AI“幻觉”给律师带来麻烦
