What we know: the stated goal of Metal is exactly the same as the goal of Mantle; reducing CPU overhead.
Hypothesis 1: Metal aims to replicate that for iOS, while Mantle can be used in the Mac Pro (which uses ATI cards)
Hypothesis 2: Metal could wrap around Mantle on OSX and some other similar interface on iOS where Mantle is not available, for a unified Apple interface without having to write their own ATI drivers
- TazeTSchnitzel 12y agoDon't Apple already write their own graphics drivers on OS X?
- sliverstorm 12y agoSorry, I was unintentionally vague, I meant without having to write their own version of Mantle. The other upside being if Metal wraps around Mantle, they can still expose Mantle to software that targets Mantle.
- TazeTSchnitzel 12y agoAh, I see. That would make sense, though if they're trying to reduce overhead, it might not be the best idea.
- wmf 12y agoI suspect Apple wants to hedge their bets between ATI and Nvidia and thus will not support Mantle (or CUDA, which exists on OS X but appears to receive no love from Apple).
