is it TRUE???
amd's mantle can power dual core cpu's so that it will never bottleneck's HIGH END GPU's???
i just read it in fragit forum........

I would believe it would.

"The design goals of Mantle are to allow games and applications to utilize the CPU and GPU more efficiently, eliminate CPU bottlenecks by reducing API validation overhead and allowing more effective scaling on multiple cores, provide faster draw routines, and allow greater control over the graphics pipeline by eliminating certain aspects of hardware abstraction inherent to the current prevailing graphics APIs"

But this API is pretty much new, and only a few game dev's are using it, so it'll take a while for AMD to do something big, and others to use it. So it'll take a while for mantle to get its self up.

It will help fewer cores/slower CPUs bottleneck High end GPUs *less*, not "never". You can't get rid of a bottleneck caused by slow hardware just by coding on a lower level. You can improve the performance by a significant amount, yes, but you won't completely remove the bottleneck.

Also, it requires the game developer to support it, and since it's AMD proprietary at the moment, expect it to be limited to whatever games AMD can seal the deal with. Thief and BF4 are the only ones I know of at the moment that come with Mantle support.

Won't bottleneck as much, but could still. Depends on the CPU, the game, and the GPU. Just makes it easier.

Well, yes, but to an extent. You need a specific GPU in order for mantle to work. But benchmarks report that an AMD APU, which has very weak CPU cores, ran significantly better with an R9 290X than it would on DX11.1. It should enable users to upgrade to a highend graphics card while still running an old, low end system, and help alleviate some bottlenecking issues. It still won't be perfect, and you would still get better performance with a more powerful CPU, but it makes highend gaming on a lowend CPU very possible. And the technology is quite new, so there is still a LOT of room for future optimization. Here are a few benchmarks:
