AMD 8000G系列处理器细节曝光：PCIe通道数减半
近日，有消息称AMD 8000G系列处理器在PCIe通道方面存在差异。据悉，该系列处理器使用两种不同类型的微架构，部分型号使用Phoenix 1,只有Zen 4核心；还有部分使用Phoenix 2,采用Zen 4+Zen 4C架构。然而，根据技嘉B650E Aorus Elite X AX Ice主板规格说明，Phoenix 1和Phoenix 2之间还存在差别。
据了解，Phoenix 2芯片支持的PCIe通道比Phoenix 1少。通过M.2插槽连接NVMe SSD仅支持2个PCIe 4.0通道，连接1块GPU仅支持4个PCIe 4.0通道。而Phoenix 1连接GPU支持8个PCIe 4.0通道，并支持全PCIe 4.0 x4接口的固态硬盘。
对于这一差异，IT之家提醒用户注意。以Ryzen 5 8500G和Ryzen 3 8300G为例，使用Phoenix 2芯片的Ryzen 8000G处理器时，较少的专用GPU通道可能会降低图形性能。而基于Phoenix 1的处理器，如Ryzen 5 8600G和Ryzen 7 8700G等，可以避免图形性能可能下降的问题。
目前，关于AMD 8000G系列处理器的具体发布时间和价格尚未公布。但从已经披露的信息来看，这款处理器在性能和功能上应该会有不错的表现。对于追求高性能的用户来说，这款处理器无疑是一个值得关注的选择。

AMD 8000G Series Processor Details Revealed: Reduced PCIe Channel Count
Recently, it was reported that there are differences in PCIe channel configuration for the AMD 8000G series processors. It is said that this series of processors uses two different types of microarchitectures, with some models using Phoenix 1 and only Zen 4 cores; while others use Phoenix 2 and adopt the Zen 4+Zen 4C architecture. However, according to the specifications of the Gigabyte B650E Aorus Elite X AX Ice motherboard, there are also differences between Phoenix 1 and Phoenix 2.
It is understood that the PCIe channels supported by the Phoenix 2 chip are fewer than those of Phoenix 1. The M.2 slot connected to NVMe SSDs supports only 2 PCIe 4.0 channels, while connecting a GPU only supports 4 PCIe 4.0 channels. On the other hand, Phoenix 1 connects the GPU to support 8 PCIe 4.0 channels and supports full PCIe 4.0 x4 interface for solid-state drives.
ITHome reminds users to pay attention to this difference. For example, when using the Ryzen 8000G processor with Phoenix 2 chip on the Ryzen 5 8500G and Ryzen 3 8300G, less dedicated GPU channels may reduce graphics performance. Meanwhile, processors based on Phoenix 1, such as the Ryzen 5 8600G and Ryzen 7 8700G, can avoid potential issues with decreased graphics performance.
At present, the specific release time and price of the AMD 8000G series processors have not been announced. However, based on the information already disclosed, this processor should perform well in terms of performance and functionality. For users who pursue high performance, this processor is definitely a worthy choice to consider.
