  Mantle is a good thing. Without it DirectX 12 wouldn't even be trying to address these issues. What we have seen thus far is that Mantle really helps slower CPU systems. It basically makes an AMD CPU and GPU combo competitive.

  I used to think DirectX 12 would kill Mantle and hurt AMD but then I realized what a genius move Mantle really was. If Mantle catches on that's great AMD sells more graphics cards AND CPUs, if DirectX 12 kills Mantle by also eliminating the CPU bottle neck that's great too because AMD processors just became a viable alternative for hardcore gamers.

  And DX is 2y from now.
  
  That is a lot of time for making sure Game Devs know Your capabilities. Like Your ways, and curse competition when it lack X or Y feature ;)

  dying to see some HSA goodness in gaming scene, using iGPUs to take load off from dGPU etc etc

  I'd love to see APU + dGPU, and use the iGPU for extra compute on top of the CPU cores (physics, AI, etc), and the dGPU for graphics.

  if Mantle adoption grows, for AMD will be a big win, for both CPU and GPU
  if the DX12 brings the same improvement of Mantle, for AMD (cpu) will be a very big win also, because the more powerfull cpu like intel i7 series will be worthless and the AMD APU will be the best choices for gaming (light to medium and why not, some probably also hardcore with some future iteration of AMD APU)

  OpenGL does the same stuff as they showed already. DX12 may not do it for a while (late 2015?) but OpenGL does it already and has for a few years. So devs, write for AMD's small subset of their own cards (only GCN) or just use OpenGL which runs on everything easily portable to everywhere. I really thought AMD would have dropped this by now and started spending more of this money on DRIVERS for all their current cards! You know, to avoid a phase4 soon etc or more driver phases for the next chips... :(

  Watch the vid at bottom AMD ;) One of your people was involved in this show, so why keep pushing proprietary for something that is already working on all cards TODAY? Proprietary crap works when you get there first and are special (doing something others can't, thus a NEED for your tech, like Cuda, it was their only choice back then, so it got entrenched). It doesn't work when there is an established product already out that does everything your proprietary stuff does cheaper. This would make more sense if OpenGL didn't exist, and only options were Mantle or DX12 which is ages away (thus Mantle would have a chance to get entrenched). SteamOS will be pushing OpenGL, and same for Android etc if a game needs a high number of draw calls etc.

  OpenGL is not the same thing as Mantle. Mantle is a low level API that operates through a much thinner driver layer and allows the devs direct control over GPU functions.

  OGL does not multithread the GPU. It reduces CPU overhead a shitload.
  And now that NV made those extensions for OGL AMD can use those techniques in Mantle.

• diogodx - Friday, May 2, 2014 - link

  More fanboys spreading FUD. The OpenGL CPU overhead redutcion extention was created by AMD.
  
  The extension "ARB_multi_draw_indirect" that Nvidia show in their market was created by Graham Selles from AMD.
