GPU的性能提升受各方面因素的影响,如:工艺、微架构设计、EDA工具、编译器等。本文仅从微架构方面分析GPU性能提升的背后发生了什么。
GPU可以粗略分为两大类:桌面/服务器端GPU和移动/嵌入式端GPU。前者的微架构设计更侧重于性能,后者更侧重于功耗和面积。前者的代表GPU厂商有NVDIA、AMD、Intel等,后者有ARM、Imagination、Qualcomm等。后文将分别介绍。
本文将通过纵向和横向对比的方式来剖析各大GPU厂商的主要微架构的变化,以及这样的变化所带来的性能提升有哪些。举例说明:所谓纵向是分析ARM的Bifrost一代和二代的改变、Bifrost三代和Valhall的改变;所谓横向是分析ARM的Bifrost和Imagination的Furian的性能差距及其原因。
