Arm推出Cortex-X925 CPU和Immortalis G925 GPU，瞄準2024旗艦設備

Arm 修改了 Cortex-X CPU 設計的命名約定，以強調其聲稱的更快的 CPU 設計。

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 宣布了最新的旗艦 CPU 和 GPU 設計，分別是 Cortex-X925 和 Immortalis G925。這些新設計將為下一代高階行動裝置提供動力，並有望比前代設備顯著提高性能和效率。

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 迄今為止最強大的 CPU 設計，與 X4 相比，單核心效能提高了 36%（根據 Geekbench 測量）。它還具有高達 3MB 的私人 L2 緩存，將 AI 工作負載效能標記時間縮短了 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.

這種新的 CPU 設計將與下一代 Cortex-A 微架構 Cortex-A725 搭配使用，Arm 聲稱與上一代 A720 相比，性能效率提高了 35%，電源效率提高了 15%。

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 也宣稱其 Immortalis G925 GPU 是迄今為止「性能最高、效率最高的 GPU」。據稱，它在圖形應用程式上比上一代 G720 快了 37%，複雜物件的光線追蹤效能提高了 52%，AI 和 ML 工作負載提高了 34%，同時消耗了 30%功率較小。

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.

該公司還將為其新的 CPU 和 GPU 設計提供“優化佈局”，聲稱這將簡化設備製造商將其納入其係統單晶片 (SoC) 佈局的流程。 Arm 表示，這種新的實體實現解決方案將加快設備的市場推出，與上一代設計相比，可能會導致採用 Arm Cortex-X925 或 Immortalis G925 的設備得到更廣泛的採用。

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.

遊戲開發者將看到虛幻引擎上的流明光線追蹤現在支援 Immortalis。這是否足以激勵更多遊戲開發商將光線追蹤整合到他們的手機遊戲中，或者這些遊戲的表現如何，還有待觀察。

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 新聞稿引述聯發科高級副總裁 JC Hsu 的話說：「聯發科致力於在我們的下一代旗艦晶片組中支援最新的 Armv9 Cortex-X925 CPU 和 Immortalis-G925 GPU 用戶端解決方案，天璣9400，今年晚些時候。

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

這表明我們可能會在 2024 年底看到新的 Vivo 或 Oppo 機型。

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.

同時使用 Arm Cortex 和 Immortalis 設計的手機並不多。聯發科技的天璣 9200 晶片為 Vivo X90、X90 Pro 和 Oppo Find X6 提供支持，是第一個採用 Arm 一流的基於硬體的光線追蹤 GPU 設計 Immortalis G715 以及 Cortex-X4 的晶片。然而，更常見的是在行動晶片中看到 Cortex 與不同的 GPU 設計搭配使用，例如三星 Galaxy S24 和 S24 Plus 中使用的三星 Exynos 2400。
