C/C++语言方面也增加了新特性，包括新建/删除、虚拟功能和Inline PTX等等。

Thrust C++模板化算法与数据结构，强大的开源C++并行算法和数据结构，类似C++ STL标准模板库；可在编译时自动选择最快的代码路径，在多核心CPU与GPU之间分配工作，编译速度加快5-10倍。

GPU加速图形处理：全新的NVIDIA Performance Primitives NPP函数库，图像处理加速10-36倍。

层纹理：适合以标准尺寸、格式处理多重纹理，性能更快，而且不会出现采样残影。

旧版的GPUDirect 1.0侧重于改进网络间通信，2.0版则侧重于改进节点内通信效率，支持P2P内存访问、传输和同步，代码更少，编程效率更高。
