AMD Radeon R7 (Bristol Ridge)

AMD Radeon R7(Bristol Ridge)是AMD移动版Carrizo APU中最快的一款集成显卡。R7目前搭配于最高端处理器型号FX9830P中,核心频率900 MHz,有512个GCN着色单元。它的技术参数相比Carrizo架构的AMD Radeon R7相同,但频率高出至少100MHz。根据不同的散热系统和热设计功率(12-45瓦),它的性能会有不小的区别。它的性能还取决于内存设置(双通道DDR4可提供最佳性能)。
架构和特性
根据AMD的信息,Radeon R7包括基于第三代GCN架构(通常称为GCN 1.2或2.0)的8个核心。因此,它与Tonga架构桌面芯片十分相似,支持DirectX 12(FL 12_0)。此外,它的着色器支持Mantle,OpenGL和OpenCL的调用。它的处理器和显卡核心同时支持HSA 1.0。
相较于Kaveri架构(Kaveri R7与GCN 1.1),它有更高的内存利用率和新的色彩压缩格式,这将可提高5-7%的游戏性能。
改进后的Carrizo/Bristol Ridge架构视频解码器现在支持UVD 6,并可以硬件解码高达4K分辨率的HVEC / H.265视频。此外,VCE(Video Codec Engine)为H.264的转码进行了改进。对Bristol Ridge架构的特性分析信息可以在我们的详尽分析文章中找到。
性能
根据从12瓦到高达45瓦不等的热设计功率设置,它在游戏中的表现会有不小差异。总的来说,由于稍高的频率,它的表现比Carrizo Radeon R7稍高。您仍然可以使用Carrizo R7的基准测试成绩来作为它的性能参考。
功耗
取决于热设计功率配置,这块28纳米制程技术芯片功耗在12-45瓦之间。因此,它可用于轻薄笔记本以及中型设备或一体机中。
