The compute capability of a device is represented by a version number, also sometimes called its “SM version”. This version number identifies the features supported by the GPU hardware and is used by applications at runtime to determine which hardware features and/or instructions are available on the present GPU.
设备的计算能力由版本号表示，有时也称为其“SM 版本”。此版本号标识 GPU 硬件支持的功能，并由应用程序在运行时用于确定当前 GPU 上可用的硬件功能和/或指令。

The compute capability comprises a major revision number X and a minor revision number Y and is denoted by X.Y.
计算功能包括一个主要修订号 X 和一个次要修订号 Y，用 X.Y 表示。

Devices with the same major revision number are of the same core architecture. The major revision number is 9 for devices based on the NVIDIA Hopper GPU architecture, 8 for devices based on the NVIDIA Ampere GPU architecture, 7 for devices based on the Volta architecture, 6 for devices based on the Pascal architecture, 5 for devices based on the Maxwell architecture, and 3 for devices based on the Kepler architecture.
具有相同主要修订号的设备具有相同的内核体系结构。对于基于 NVIDIA Hopper GPU 架构的设备，主要修订号为 9，对于基于 NVIDIA Ampere GPU 架构的设备，8 对于基于 Volta 架构的设备，7 对于基于 Volta 架构的设备，6 对于基于 Pascal 架构的设备，5 对于基于 Maxwell 架构的设备，以及 3 对于基于 Kepler 架构的设备。

The minor revision number corresponds to an incremental improvement to the core architecture, possibly including new features.
次要修订号对应于对核心架构的增量改进，可能包括新功能。

Turing is the architecture for devices of compute capability 7.5, and is an incremental update based on the Volta architecture.
Turing 是计算能力为 7.5 的设备架构，是基于 Volta 架构的增量更新。

CUDA-Enabled GPUs lists of all CUDA-enabled devices along with their compute capability. Compute Capabilities gives the technical specifications of each compute capability.
启用 CUDA 的 GPU 列出所有支持 CUDA 的设备及其计算能力。 计算能力 提供了每种计算能力的技术规格。

The compute capability version of a particular GPU should not be confused with the CUDA version (for example, CUDA 7.5, CUDA 8, CUDA 9), which is the version of the CUDA software platform. The CUDA platform is used by application developers to create applications that run on many generations of GPU architectures, including future GPU architectures yet to be invented. While new versions of the CUDA platform often add native support for a new GPU architecture by supporting the compute capability version of that architecture, new versions of the CUDA platform typically also include software features that are independent of hardware generation.

不应将特定 GPU 的计算能力版本与 CUDA 版本（例如 CUDA 7.5、CUDA 8、CUDA 9）混淆，后者是 CUDA 软件平台的版本。应用程序开发人员使用 CUDA 平台创建在多代 GPU 架构上运行的应用程序，包括尚未发明的未来 GPU 架构。虽然 CUDA 平台的新版本通常会通过支持该架构的计算能力版本来添加对新 GPU 架构的原生支持，但 CUDA 平台的新版本通常还包括独立于硬件代系的软件功能。

The Tesla and Fermi architectures are no longer supported starting with CUDA 7.0 and CUDA 9.0, respectively.
从 CUDA 7.0 和 CUDA 9.0 开始，不再支持 Tesla 和 Fermi 架构。
