Amazon Web Services has transitioned its latest custom ARM-based server processor to production, launching the first EC2 instances powered by the Graviton5 chip. The new instances promise a substantial performance boost over the prior generation, potentially offering a more compelling proposition for cost-conscious cloud workloads.
Benchmark results from Phoronix reveal that Graviton5 achieves a 30% geometric mean performance improvement over Graviton4, tested across a wide array of workloads. This indicates a broad generational advancement rather than niche optimizations.
The technical specifications highlight the drivers behind this gain. Graviton5 is built on the Arm Neoverse-V3 core architecture, evolving from the Neoverse-V2 cores in Graviton4. AWS has increased the maximum core count per chip to 192 and raised the base clock speed to 3.3GHz, up from 2.8GHz in the previous generation, directly enhancing single-threaded and general compute capabilities.
The first instances to incorporate Graviton5 are the M9g and M9gd general-purpose models, which have now reached general availability. The "d" in M9gd signifies instances with local NVMe storage, providing options for workloads requiring low-latency, high-throughput disk access.
This release follows AWS's initial announcement of the Graviton5 chip in December 2023. The general availability of these instances gives cloud architects and developers a more powerful ARM-based option for running diverse applications, from web servers to data processing and microservices.
Adopting newer, more efficient CPU architectures is a key strategy for cloud providers aiming to improve price-performance ratios. By designing its own silicon, AWS can tailor performance, power efficiency, and feature sets to its cloud environment's specific needs. For organizations on AWS, evaluating migration to instance types like the M9g series becomes a practical step toward potentially reducing cloud spending for equivalent or enhanced performance. The continued investment in ARM technology also reinforces its growing dominance in the server market, challenging traditional x86 offerings.
亞馬遜網絡服務已將其最新的定制ARM架構伺服器處理器投入量產，推出首款搭載Graviton5芯片的EC2實例。這款新實例承諾較前代產品實現顯著性能提升，有望為注重成本效益的雲端工作負載提供更具吸引力的方案。
Phoronix的基準測試結果顯示，Graviton5在廣泛的工作負載測試中，幾何平均性能較Graviton4提升30%。這代表其進步是全面性的世代提升，而非僅限於特定優化。
技術規格揭示了此性能提升的驅動因素。Graviton5基於Arm Neoverse-V3核心架構構建，演進自Graviton4的Neoverse-V2核心。AWS將單芯片最大核心數增至192個，並將基礎時脈頻率從上一代的2.8GHz提升至3.3GHz，直接增強了單線程及通用運算能力。
首批採用Graviton5的實例為M9g及M9gd通用型實例，目前已正式發佈。M9gd型號中的「d」代表配備本地NVMe儲存的實例，為需要低延遲、高吞吐量磁碟存取的工作負載提供選擇。
此次發佈緊隨AWS於2023年12月首次公布Graviton5芯片之後。這些實例的正式推出，為雲端架構師及開發人員提供了更強大的ARM架構選項，以運行從網絡伺服器、數據處理到微服務的各類應用。
採用更新、更高效的CPU架構，是雲端服務商提升性價比的關鍵策略。透過自主設計芯片，AWS能針對其雲端環境的特定需求，在性能、能效及功能套件方面進行客觀定制。對於使用AWS的機構而言，評估遷移至M9g系列實例，成為實現同等或更佳性能同時降低雲端開支的可行途徑。持續投入ARM技術的發展，亦鞏固了其在伺服器市場日益主導的地位，對傳統x86方案構成挑戰。
