gem5是一款面向通用处理器(主要是cpu,也有部分的gpu支持)的体系结构模拟器,与vcs,verilator这类cycle-accurate的RTL仿真不同,gem5的建模是基于Python/C++,Python做配置,C++做底层实现,是一种事件驱动的非周期精确的仿真,速度更快,非常有利于在芯片规格定义阶段快速评估芯片的性能, @天外飞仙 大佬这里已经有比较完善...

如今异构计算(Heterogeneous Compute,HC)已经部署在消费类移动设备中,与传统架构相比可以将矩阵工作负载的性能提高50倍。同时,这也将性价比和功耗节省提高了150倍以上。企业HC可能会使用与消费HC相同的技术。因此,异构计算的改进将大幅提升实时矩阵工作负载的价值,尤其是那些AI推理工作负载的子集。
使用Compute Benchmark测试系统的游戏,图像处理或视频编辑潜力。通过支持OpenCL,CUDA和Metal API来测试GPU的功能。新功能是对Vulkan的支持,Vulkan是下一代跨平台图形和计算API。3、跨平台 比较苹果和橘子。或苹果和三星。它专为跨平台比较而设计,可让您比较不同设备,操作系统和处理器架构的系统性能。
