AMD的Robert Hallock在推特上面分享了一些關於Mantle的新話題
Mantle將可以讓多顯卡變成一個大GPU，可用的記憶體總量上可以疊加



Mantle is the first graphics API to transcend this behavior and allow that much-needed explicit control. For example, you could do split-frame rendering with each GPU ad its respective framebuffer handling 1/2 of the screen. In this way, the GPUs have extremely minimal information, allowing both GPUs to effectively behave as a single large/faster GPU with a correspondingly large pool of memory.

Ultimately the point is that gamers believe that two 4GB cards can’t possibly give you the 8GB of useful memory. That may have been true for the last 25 years of PC gaming, but thats not true with Mantle and its not true with the low overhead APIs that follow in Mantle’s footsteps. – @Thracks (Robert Hallock, AMD)

大致上就是透過split-frame rendering技術，可以讓兩張顯卡各自負責render一半的畫面
