高通正式发布了基于Oryon的中央处理器（CPU），用于其下一代骁龙平台。
高通于8月25日表示，其第四代基于Oryon的CPU成为全球首款达到5GHz时钟速度的移动芯片。1GHz代表每秒十亿个周期。Oryon是高通自研的基于Arm的CPU微架构，专为高性能和能效而设计。
高通通过全定制设计实现了这一时钟速度，而非仅依赖半导体代工厂的先进工艺节点。公司自行设计和调优了微架构、实现选择和CPU子系统，从而克服了移动芯片组的功耗和热约束。
该CPU还提供高每周期指令数（IPC），这是衡量处理器在每个时钟周期内可执行工作量的指标。高时钟速度与IPC的结合，旨在为实际工作负载（包括应用启动、网页浏览、高端游戏和内容创作）提供更快的性能。
该架构还适合运行代理式人工智能（AI）。代理式AI执行CPU密集型任务，如使用工具、读写文件和验证规则，这增加了CPU在控制和协调整个系统方面的重要性。

第四代Oryon CPU引入了名为Qualcomm Oryon FlexCache的缓存架构。它在现有缓存层级的基础上，增加了另一层以最大化性能。
缓存将常用数据临时存储在CPU核心附近，使处理器无需访问主内存即可快速检索。现有的Oryon架构在每个CPU核心内放置L1指令缓存，并在核心旁边的CPU复合体中放置L2缓存。
FlexCache是一个共享缓存池，可被具有不同特性的异构核心访问。缓存容量根据工作负载动态分配。在重负载下，高性能Prime核心可以利用大部分FlexCache池。
FlexCache允许大型工作集保留在缓存中，而不是溢出到系统内存。这减少了系统内存访问的频率，并有助于在可用内存受限时维持性能。高通表示，该架构可以改善要求苛刻的工作负载的性能，包括代理式AI、游戏、多任务处理和视频编辑。
“你要求手机做的事情不再是一个单一任务，而是一个贯穿整个CPU的单一计划，”高通高级总监Francisco Cheng表示。他说，5GHz Oryon CPU为这些工作负载设定了节奏，而FlexCache在任务在核心之间移动时保持数据对核心可用。
第四代Oryon CPU在定于9月举行的Snapdragon Summit 2026之前发布。高通瞄准日益细分的旗舰智能手机市场，涵盖基础版、Pro版和Ultra版，以及翻盖和折叠屏手机。

Qualcomm has officially unveiled a new Oryon-based central processing unit (CPU) for its next-generation Snapdragon platform.
Qualcomm said on Aug. 25 that its fourth-generation Oryon-based CPU became the world's first mobile chip to reach a clock speed of 5GHz. One gigahertz represents one billion cycles per second. Oryon is Qualcomm's custom-designed, Arm-based CPU microarchitecture built for high performance and power efficiency.
Qualcomm achieved the clock speed through a fully custom design rather than relying solely on advanced process nodes from semiconductor foundries. The company designed and tuned the microarchitecture, implementation choices and CPU subsystem itself, allowing it to overcome the power and thermal constraints of a mobile chipset.
The CPU also delivers high instructions per cycle (IPC), a measure of how much work a processor can perform during each clock cycle. The combination of high clock speeds and IPC is designed to deliver faster performance in real-world workloads including app launches, web browsing, high-end gaming and content creation.
The architecture is also suited to running agentic artificial intelligence (AI). Agentic AI performs CPU-intensive tasks such as using tools, reading and writing files and validating rules, increasing the importance of the CPU in controlling and coordinating the overall system.

The fourth-generation Oryon CPU introduces a cache architecture called Qualcomm Oryon FlexCache. It builds on the existing cache hierarchy while adding another layer designed to maximize performance.
Cache temporarily stores frequently used data close to CPU cores, allowing the processor to retrieve it quickly without accessing main memory. The existing Oryon architecture places an L1 instruction cache inside each CPU core and an L2 cache in the CPU complex adjacent to the cores.
FlexCache is a shared cache pool that can be accessed by heterogeneous cores with different characteristics. Cache capacity is dynamically allocated depending on the workload. Under heavy workloads, high-performance Prime cores can draw on most of the FlexCache pool.
FlexCache allows large working sets to remain in cache rather than spilling into system memory. This reduces the frequency of system-memory access and helps sustain performance even when available memory is constrained. Qualcomm said the architecture can improve performance in demanding workloads including agentic AI, gaming, multitasking and video editing.
"What you ask your phone to do is no longer a single task but a single plan that runs across the entire CPU," said Francisco Cheng, senior director at Qualcomm. He said the 5GHz Oryon CPU sets the pace for those workloads, while FlexCache keeps data available to the cores as work moves between them.
The fourth-generation Oryon CPU was unveiled ahead of Snapdragon Summit 2026, scheduled for September. Qualcomm is targeting the increasingly segmented flagship smartphone market, spanning base, Pro and Ultra models to flips and foldables.
