借這串問個問題
intel和AMD在CPU內導入顯示核心
而且可以用來加速像轉檔之類的運算
可是要達成這點需要特殊軟體支援嗎?
還是單純用內建的GPU核心做OPENCL或DX11的運算?
|
不用特殊軟體應該也可以
CPU跟GPU在同一顆晶片上
相互之間傳輸資料的時間縮短
性能當然會有所提升
但有針對這點設計的軟體表現應該會更好
我用MediaCoder x64 (free software)轉檔
可以選擇

1. CPU Only
Using regular CPU processing, slower but best quality. If you are encoding in formats other than H.264, please always choose this.

2. nVidia CUDA
If your system has supported nVidia display adapter, you can choose this to utilize CUDA acceleration in H.264 encoding. It's not recommended for use with lower bitrate due to reduced compression quality.

3. Intel Media SDK
If your system is a Intel G45 or later Sandy Bridge platform, you can choose this to utilize accleration provided by Intel Media SDK. This feature is available in MediaCoder 2011 RC3 or later.
