Introduction
Just a week after the launch of two Ryzen 9000 series desktop processors based on the Zen 5 architecture with single CCD configurations, two higher-end Ryzen 9 models with dual CCDs quickly followed. Among them, the flagship Ryzen 9 9950X retains the original naming convention and continues to feature a full 16-core setup.
Product Specifications
As part of the Zen 5 architecture, the Ryzen 9 9950X also utilizes a chiplet design, comprising two complete CCDs, each with 8 cores, manufactured using TSMC’s 4nm FinFET process. Each CCD has 16MB of L3 cache, totaling 32MB, and supports PCIe 5.0, offering 28 PCIe lanes and 4 USB 3.2 Gen 2 10Gbps expansion ports. The integrated RDNA 2 architecture provides a graphics core with a base frequency of 2200MHz and 2 compute units, delivering basic graphics processing capabilities.
Compared to the previous generation Ryzen 9 7950X, the base clock frequency of the Ryzen 9 9950X has been reduced to 4.30GHz, while the maximum boost frequency remains at 5.70GHz. The TDP is still rated at 170W, but unlike the Ryzen 9 7950X and the 170W preset in AMD Eco Mode, the default PPT power limit for the Ryzen 9 9950X has been increased to 200W, providing a higher performance threshold than the previous limit of 230W.
Performance Evaluation
In single-threaded performance, the Ryzen 9 9950X scores around 2000 points in Cinebench R23, while its multi-threaded score reaches 25000 points, approximately 1.7 times that of the Ryzen 7 9700X. This processor excels in productivity applications that rely on multi-threading, matching or even exceeding the performance of the 14th Gen Core i7 and i9, which have a significant number of E cores.
In gaming, the Ryzen 9 9950X performs similarly to the Ryzen 7 9700X and competes well with rivals in most scenarios. At 1080p and 1440p resolutions, it maintains stable frame rates, providing a smooth gaming experience.
Thermal and Power Management
Regarding heat and temperature control, the Ryzen 9 9950X features an improved design that optimizes the default parameters for its 170W TDP. In standard configurations, it effectively balances performance output and thermal management, reducing power consumption compared to previous generations. Testing shows that under heavy load, the processor maintains temperatures around 85°C, performing well with standard cooling solutions. This enhancement simplifies the selection of cooling and power supply units for users and significantly boosts confidence in long-term stability, making the performance upgrade for desktop CPUs more practical and achievable.
介绍
在搭载了单 CCD 配置的两款基于 Zen 5 架构的 Ryzen 9000 系列台式机处理器上市的一周后，定位更高且搭载了两颗 CCD 配置的两款 Ryzen 9 迅速跟进。其中，顶配款 Ryzen 9 9950X 沿用了原有的命名规则，并依旧搭配了完整的 16 核心配置。
产品规格
作为 Zen 5 架构的成员，Ryzen 9 9950X 同样采用了芯片组设计，搭载了两颗完整的 8 核心 CCD，由 TSMC 4nm FinFET 工艺制造。每颗 CCD 拥有 16MB 的 L3 缓存，合计 32MB，同时支持 PCIe 5.0，提供 28 条 PCIe 通道和 4 个 USB 3.2 Gen 2 10Gbps 扩展接口。内置的 RDNA 2 架构核显，标称频率为 2200MHz，具备 2 个计算单元，提供基础的图形处理能力。
与上一代的 Ryzen 9 7950X 相比，Ryzen 9 9950X 的标称基准频率调低至 4.30GHz，而标称最大频率保持在 5.70GHz。标称 TDP 功耗仍为 170W，但与 Ryzen 9 7950X 及 AMD Eco Mode 预设的 170W 档位不同，Ryzen 9 9950X 的默认 PPT 功耗限制提高至 200W，较前代的 230W 限制提供了更高的性能释放空间。
性能评测
在单线程性能方面，Ryzen 9 9950X 在 Cinebench R23 中的得分达到了 2000 分，而在多线程性能方面，得分则高达 25000 分，约为 Ryzen 7 9700X 的 1.7 倍。该处理器在偏重多线程性能的生产力应用中表现出色，可以与拥有大量 E 核的第 14 代 Core i7 和 i9 相媲美。
在游戏性能方面，Ryzen 9 9950X 的表现与 Ryzen 7 9700X 相当，并在大多数场景下与竞争对手的表现相似，尤其在 1080p 和 1440p 分辨率下，帧率保持稳定，提供流畅的游戏体验。
发热与温度控制
在发热与温度控制方面，Ryzen 9 9950X 采用了改进的设计，优化了与 TDP 170W 的默认参数规则。在默认档位下，有效平衡了性能释放与温度控制，相比前代降低了功耗。测试显示，在高负载情况下，处理器的温度保持在 85°C 左右，使用标准散热器时表现良好。这一改进让用户在选择散热器和电源时更加轻松，也大大提升了使用体验和对产品长期稳定性的信心，使得台式机 CPU 的性能升级变得更加合理和可行。
