AMD GPU14 Tech Day Event - Sept 25'th

I think people have to start thinking in terms of power consumption first. Because 20% of a CPU core may not be huge (though other algorithms may require more resources) but it's a significant amount of power, which probably dwarfs what TrueAudio requires.

And power saved is power that can be spent on extra performance (via Turbo).

How can we compare when you provide a benchmark at a resolution the ps3 is incapable of ?
plus the situation is not the same today a lot of work has been done to make dx11 leaner

Can you say whether it's going to be a public API/spec or whether it'll only be under NDA for specific folks?

Great, yeah I look forward to hearing the details!

Thanks for the clarification Nick.

 

I agree, also with the TrueAudio part.

Well, apart from Oblivion, the other three descriptors in that benchmark are not met with the PS3: High Quality, 1280x1024 and HDR. Especially the latter let Oblivion performance tank on G70-class hardware.

 

I'm not sure why anyone thinks this is bad for MS or Sony. This won't have any impact on them at all. This is entirely about getting a competitive advantage out of software because there's no way for AMD to get a big enough advantage out of hardware to change their marketshare situation. And that's smart, but let's not act as if this changes any of the market dynamics that exist for consoles or OSes.

For MS, Windows PCs are dominant in the market this would apply to, and not because MS has a lock on gaming related APIs. And no one that really wants a console gaming experience is going to jump ship to PC gaming, which will still have all of it's existing issues despite this. PCs have been stronger than consoles pretty consistently and it hasn't changed the dynamics of that market. This is just more performance.

If SteamOS is successful it'll be successful regardless of what AMD is doing; having access to the same functionality as Windows isn't going to be a competitive advantage for Valve.

 

Isnt Carmack was praise for low level API during all this years ? I think remember this was his main battle ... what the problem ? its not Nvidia or ?

I really well imagine Nvidia presenting Mantle, and seeing Carmack coming in the scene explaining how great it is.

 

In our experience, DX11 deferred contexts give no performance gains at all, the opposite actually, so have completely given up on it which is sad but true.
See my slide #34 here:

Two questions:
For me most interesting question not really clarified is Mantle will come to MacOS, really? that
would put MacOS from now currently OGL 3.2 support (DX10 more or less) (right 4.1 (partial DX11
features) is around the corner) to state of the art.. Dave Baumann can AMD is interested in true
cross-platform support for Mantle i.e. Win,Lin+MAC..

Also other question is about StreamOS:
Do you expect solid StreamOS Intel GPU support (for Intel only StreamBoxes (i.e. without AMD or NV GPUs)) to ignite interest in Intel to have OGL Intel Win binary drivers ported to Linux now Win OGL drivers offer GL 4.2+key parts of GL 4.3 like compute shaders (i.e. full DX11 parity).. in contrast current Intel Linux efforts have Mesa at GL 3.3 this year perhaps and not full 4.0 even in years to come..

 

the R9 280xt or whatever the top line chip is already far and away more powerful than next gen systems and will most likely beat them out to customers. Next year we will see the first 20nm gpus and it will explode the gap.

We should finally get a new bulldozer over the next year and we will get broadwel . So I think by the end of 2014 any advantage a console might have will be gone.

 

I don't get your post, I just pointed out that he said that MSFT and Sony may not be that happy about the hardware vendors and content creators showing some willingness to break away from the constrained (when not closed) environments MSFT and SOny want them to be locked in.

How that anything to do with Nvidia? Or some good relation JC would hae with Nvidia?

 

Thanks for the response! Is this API going to be open? It could be pointless since it must be closely tied to AMD hardware and synergistic w/ AMD tools written for consoles so w/o a tight mapping of commands and functions to hardware level instructions, using mantle could be moot. Looking forward to it though.

 

From TechSpot (and no doubt gazillion other sources)

 

I don't believe it, or rather I'm sure there was a miscommunication/misinterpretation involved. Even if AMD intends to publicly disclose the API/specification, they have made it very clear that it is designed to target GCN... not older AMD architectures, definitely not other hardware vendor's architectures. Besides, if they were really intending to make it portable to other hardware there would be no reason to not propose it to Microsoft/Khronos and try to do it through changes to DX/GL first. To my knowledge, they haven't done anything of the sort.

Feel free to correct me if I'm wrong Dave, but I doubt it.

 

I'm not saying this isn't something that couldn't develop into broader industry support; I'm responding specifically to the claims that someone will be able to take Mantle as it is today (or rather, in December) and support it on non-GCN hardware for the purposes of running BF4's new path or similar. That I seriously doubt.

In terms of affecting future APIs, absolutely these things are always evolving and I hope that's a direction AMD intends to pursue. But the resulting APIs would still be evolutions of DirectX/GL, even if a clean break is needed. In my opinion that's the ideal direction to go here unless it's proven than *any* abstraction/portability makes too large a performance sacrifice. That has yet to be established though.

I guess a lot of this is going to remain fairly unclear until November when more details are given.

 

Thanks for the info.

I really hope Mantle gets the same kind of support. If NVIDIA adopted it, it would be fantastic news for the PC gaming world.

 

No not really.

PS3 came out in late 2006. The RSX GPU was a cut down version of the NV47 / G70. As mentioned it had half the ROPs and memory bus width of the high-end PC versions.

On top of that, Nvidia had already launched the G80 for PCs so PS3 most certainly did not have an almost top of the line GPU at the time it launched.

 

I've always wondered if it is really half, or if the other half was just hooked up to the CPU memory pool.
