Arm推出Cortex-X925 CPU和Immortalis G925 GPU，瞄准2024年旗舰设备

Arm 修改了 Cortex-X CPU 设计的命名约定，以强调其声称的更快的 CPU 设计。

Arm has announced its latest flagship CPU and GPU designs, the Cortex-X925 and Immortalis G925, respectively. These new designs are set to power the next generation of high-end mobile devices, promising significant performance and efficiency improvements over their predecessors.

Arm 宣布了其最新的旗舰 CPU 和 GPU 设计，分别是 Cortex-X925 和 Immortalis G925。这些新设计将为下一代高端移动设备提供动力，有望比前代设备显着提高性能和效率。

The Cortex-X925 is Arm's most powerful CPU design to date, offering a 36 per cent increase in single-core performance compared to the X4 (as measured by Geekbench). It also features a 41 per cent improvement in AI workload performance time to token, with up to 3MB of private L2 cache.

Cortex-X925 是 Arm 迄今为止最强大的 CPU 设计，与 X4 相比，单核性能提高了 36%（根据 Geekbench 测量）。它还具有高达 3MB 的私有 L2 缓存，将 AI 工作负载性能标记时间缩短了 41%。

This new CPU design will be paired with the next generation of Cortex-A microarchitectures, the Cortex-A725, which Arm claims offers a 35 per cent improvement in performance efficiency over the previous generation's A720 and a 15 per cent increase in power efficiency for the Cortex-A520.

这种新的 CPU 设计将与下一代 Cortex-A 微架构 Cortex-A725 搭配使用，Arm 声称与上一代 A720 相比，性能效率提高了 35%，电源效率提高了 15%。皮质-A520。

Arm is also touting its Immortalis G925 GPU as its "most performant and efficient GPU" to date. It is claimed to be 37 per cent faster on graphic applications than the previous generation G720, with a 52 per cent boost in ray-tracing performance with complex objects and a 34 per cent improvement in AI and ML workloads — all while consuming 30 per cent less power.

Arm 还宣称其 Immortalis G925 GPU 是迄今为止“性能最高、效率最高的 GPU”。据称，它在图形应用程序上比上一代 G720 快了 37%，复杂对象的光线追踪性能提高了 52%，AI 和 ML 工作负载提高了 34%，同时消耗了 30%功率较小。

The company will also provide "optimised layouts" of its new CPU and GPU designs, which it claims will simplify the process for device manufacturers to incorporate into its system on chip (SoC) layouts. Arm suggests that this new physical implementation solution will expedite the market launch of devices, potentially leading to broader adoption of devices featuring the Arm Cortex-X925 or Immortalis G925 compared to those with its previous generation designs.

该公司还将为其新的 CPU 和 GPU 设计提供“优化布局”，声称这将简化设备制造商将其纳入其片上系统 (SoC) 布局的流程。 Arm 表示，这种新的物理实现解决方案将加快设备的市场推出，与上一代设计相比，可能会导致采用 Arm Cortex-X925 或 Immortalis G925 的设备得到更广泛的采用。

Game developers will see Lumen ray tracing on Unreal Engine now supporting Immortalis. Whether this will sufficiently motivate more game developers to integrate ray tracing into their mobile games or how well those games would perform remains to be seen.

游戏开发者将看到虚幻引擎上的流明光线追踪现在支持 Immortalis。这是否足以激励更多游戏开发商将光线追踪集成到他们的手机游戏中，或者这些游戏的表现如何，还有待观察。

MediaTek Senior Vice President JC Hsu, Corporate Senior Vice President at MediaTek, was quoted in Arm's press release as saying: "MediaTek is dedicated to supporting the latest Armv9 Cortex-X925 CPU and Immortalis-G925 GPU Client solution in our next-generation flagship chipset, Dimensity 9400, later this year."

Arm 新闻稿援引联发科高级副总裁 JC Hsu 的话说：“联发科致力于在我们的下一代旗舰芯片组中支持最新的 Armv9 Cortex-X925 CPU 和 Immortalis-G925 GPU 客户端解决方案，天玑 9400，今年晚些时候。”

This suggests that we may see new Vivo or Oppo models by the end of 2024.

这表明我们可能会在 2024 年底看到新的 Vivo 或 Oppo 机型。

Not many phones use Arm's Cortex and Immortalis designs in tandem. MediaTek's Dimensity 9200 chip, which powered the Vivo X90, X90 Pro, and Oppo Find X6, was the first to employ Arm's premier hardware-based ray-tracing GPU design, the Immortalis G715, alongside the Cortex-X4. However, it is more usual to see the Cortex paired with a different GPU design in a mobile chip, such as Samsung's Exynos 2400, found in Samsung's Galaxy S24 and S24 Plus.

同时使用 Arm Cortex 和 Immortalis 设计的手机并不多。联发科技的天玑 9200 芯片为 Vivo X90、X90 Pro 和 Oppo Find X6 提供支持，是第一个采用 Arm 一流的基于硬件的光线追踪 GPU 设计 Immortalis G715 以及 Cortex-X4 的芯片。然而，更常见的是在移动芯片中看到 Cortex 与不同的 GPU 设计搭配使用，例如三星 Galaxy S24 和 S24 Plus 中使用的三星 Exynos 2400。
