Ivy Bridge的整合图形核心第一次为Intel带来了GPU OpenCL并行计算能力，但因为开发包的限制，发布之初只停留在纸面上。今天，Intel放出了新版Media SDK 2012 R2，Ivy Bridge集显终于可以执行OpenCL计算了。

借助新的Intel SDK for OpenCL Applications 2012，开发人员可以在Ivy Bridge CPU处理器、GPU图形核心上同时实现OpenCL，这也是继AMD Fusion APU之后业内第二套可以做到这种异构加速计算的平台。

Ivy Bridge HD Graphics图形核心支持DirectCompute、OpenCL 1.1计算标准。根据此前测试，DirectCompute性能还不错，好的情况下甚至能够超过A8-3870K、Radeon HD 5570。下一代Haswell还将升级支持OpenCL 1.2。

Intel的新开发包还支持蓝光MVC立体视频的编码、解码，视频会议的动态码率控制、抗误码(鲁棒性)、错误检测与报告、耕地延迟更快响应，同时只需要一个简单的API，就能让开发人员在Ivy Bridge处理器使用Quick Sync Video引擎进行硬件加速视频转码。
