Comments on: AMD Defends Against Claims That Mantle Is Only A Temporary Solution Before DirectX 12 Launches

I’m rooting for mantle to take off and steal some titles from games that would otherwise use DX12. It’s an open standard, mostly ready, and cross-platform. I’m usually using a linux box and I’d love to see the number of games with good native-level performance on linux increase. Even if a game uses mantle but only offers Windows support the linux gamers will win because it’d only be a matter of time before WINE could leverage native linux Mantle libraries and only do translation on the non 3D program calls. Khronos has promised OGL NG “soon” but who knows how long soon is in Khronos estimation time. And Nvidia users can also benefit from Mantle if Nvidia just comes around and provides the driver support; if the standard catches on they’d almost certainly be forced to.

“You don’t throw your screwdriver away because you currently need a wrench,”

Horrible analogy. If Mantle is a screwdriver then DX is a multitool.

You have two keys, the first one that is good at opening a certain brand
of lock, and the second that can open every brand of lock in the
market.

I would throw away that first key.

If DX12 is a Windows 10 only feature. and Mantle is an AMD only feature, i don’t see real progress coming to the PC platforms any time yet. Still Mantle obligated Microsoft to release DX12 and that’s only a good thing.

When DirectX12 launches it will still be second rate compared to OpenGL. Mantle has a chance to catch OpenGL with version 2 but DX12 does not it can’t as OpenGL is a hardware feature in it’s self with no driver overhead what so ever. Mantle can become like that but DirectX will always need at least some driver overhead.

OpenGL has support for upto 140,000 draw calls with proper optimization nearly 1.5 times as many as Mantle right now & has had this ability for along time. Mantle 2 will equal this while DX12 sits back at roughly 90,000 max if it’s like mantle 1.

I’d still use mantle and OGL/N regardless of how far DX goes. Why? Because they’re both open-standard APIs.

Yes, Mantle can potentially come to linux, but that would be well after the official release.

“Nobody but certain governments have ever seen the windows source code. ”

My mistake, I thought you were referring to the DirectX source code. In that case you do have a point here.

“Yea we do know direct x does more than mantle. Mantle is for CPU optimization. Direct x handles CPU, GPU, apu, I/O, and interface.”

Mantle is for CPU, GPU, and APU/SoC optimization as well, but it’s mainly optimized for AMD’s GCN hardware (though it can easily be optimized by any company for any hardware)

I maintain, we don’t yet know if DirectX12 can do more than mantle.

In reply to d0x360. OpenGL is still better, way better.

If by partner you mean Microsoft is saying this is what we are doing then yes.

Yea we do know direct x does more than mantle. Mantle is for CPU optimization. Direct x handles CPU, GPU, apu, I/O, and interface.

Yes AMD and Microsoft worked together on the Xbox and no they dont directly compete with each other but direct x is an apk toolset for making games. It works exactly the same regardless of GPU, CPU or apu manufacturer or spec. That’s why its widely used. It doesn’t care what the hardware is all it does is facilitate the communication between the kernal and the hardware with a standard set of secure instructions.

Mantle and dx12 have overall different goals it just so happens that one of the many goals of DX is shared with mantle.
