Must have missed that. Have a link?
One of the major benefits of going Mantle is the lower CPU usage the GPU would have on it. Typical OpenGL/DX API's require a process that looks like this.The did say they were running on a downclocked 8350 as well as the game being played by two AI players.
Sorry, cant find a direct one, I'll try later.
In the meantime, if you google the following text:
Mantle is not tied to AMD's GCN
There are many links to what was discussed at the AMD Developer Summit by Johan Andersson.
So Mantle doesn't work with Intel CPUs?
You mean Johan's wish list for what he would like to see from Mantle? Notice the "?" on the slide for multi-vendor? If it was a fact why the use of a "?" and not something more appropriate like an exclamation point?
...
No it isnt.For developers, that's the whole point of Mantle. You don't want to alienate your customers because you can't get your game to run acceptably on their hardware. Mantle caters specifically to relatively new hardware, like the 7000 and 200 series cards. Even though the architecture of the 5000/6000 are very similar to the GCN hardware, it isn't supported. Not because it isn't best suited, but marketing.
Erm, thats why I said its why Mantle exists.Uh, that's the reason why Mantle exists.
Is this refuting anything I said?The drivers handles everything going on, which is why Mantle gives all that control over to developers.
What does any of this prove?OpenGL was actually made by SGI for their graphic cards, and then they later opened up the API. Glide, which is exactly just like Mantle, was created by 3DFX and became open source.
I'm not a fan of an increase in the number of APIs if they are not universal.I don't like NVAPI or Mantle. Though to be fair, NVAPI is 5 years old and does support older hardware. You could use OpenGL and throw in some custom extensions. Both Nvidia and ATI have been doing that for years, before DirectX because the thing of the future.
For example, Nvidia has created a number of custom OpenGL extensions that ATI has to use just to be compatible, and vice versa. But Nvidia has created so many more and has gotten developers to use them more often, that it's no wonder why Nvidia is usually higher in performance then ATI was.
It's not like Mantle where you created an entire API, but it does give a decent performance boost without having developers to create whole new code.
GCN versions 1 and 2 are required to run Mantle.
http://en.wikipedia.org/wiki/Mantle_(API)
This why Nvidia will not support it.
They will have to create a arch that will play nice with it. They're in a better position to work on their own version and roll it out faster.
Remember, single card multi-monitor support wasn't available until Kepler, Fermi couldn't support it. Also, they called it Surround instead of Eyefinity.
I doubt Nv will call their version Mantle, they'll make up a different name.
Mantle isn't a driver, the arch is what makes Mantle possible. Try to run Mantle on a 5870 and see where that get you.
No, there was a slide produced during a presentation.
I finally found a copy of it, but I'm burned out researching this today to find the original.
The text is this:
Multi Vendor?
Mantle is designed to be a thin hardware abstraction
- not tied to AMDs GCN
- forward compatible
- extensions for architecture- and platform-specific functionality
Mantle would be a much more efficient graphics API for other vendors as well
- most Mantle functionality can be supported on todays modern GPUs
edit, I meant to say no thats not how it is written.
Note that he states what Mantle is.
The question being asked on the slide is whether it will be used by multiple vendors, not whether it is capable.
Andersson stated from what he saw in the code he doesn't see why other GPU's couldn't run full or parts of Mantle. As of now and for the foreseeable future it is completely locked to GCN. AMD has yet to officially announce they are allowing other GPU devs to have Mantle. It has all been conjecture and maybes.
It still isn't really here yet, until then it is all just hyperbole.

I am truly excited for this. It's been rumored that Mantle will allowed for unparalleled ease in porting games between consoles and PCs (on top of the now mutual use of x86 architectures between PCs and the next-gen consoles). Can't wait.
Yeah I didnt realise we were talking about the same thing, but it wasnt a wish list.Please fully read posts before you comment back. In fact I acknowledged Andersson statement that Mantle may work on non-GCN. As of now it is tied to GCN because of AMD.
I havent said that AMD intends to give other vendors full access to Mantle.I asked you to provide proof AMD intends to give other GPU devs full access to Mantle.
Mmm.... extensions. How do they work?that porting bonus is only as long as PC GPUs use GCN, when AMD moves off GCN that's obsolete
I'd say it's here because Dice and other devs are using it And have announced titles after BF4 going forward. I mean seriously, how dumb of a statement could you make saying it isn't here?
that porting bonus is only as long as PC GPUs use GCN, when AMD moves off GCN that's obsolete
That was the lowest FPS I saw it hit during the video and to be fair he stated that it was running at about 30fps. Watching it I saw it spike from 60 at its highest to 34 at its lowest which I don't feel is something that is that unusual as the high fps spots were pushed in views only having to render one ship and a couple of beams whereas the 34fps areas were rendering the entire battle.
Frankly its a new thing and it will take time to be optimized and implemented correctly, I'm not holding my breath and I don't expect massive gains from it. Right now I get the FPS that I want in the games I play, if I don't get a boost no biggs but if I do it will be a nice bonus.
EDIT:
The "Average Frames" is measured in MS.
You are just crying butt hurt tears because of regret of buying Nvidia. LOL. Take it like man. AMD stock value is also rising. Nvidia is going to lose stock price value. Mark my words. Nvidia = KO'ed
"Unparalleled ease". An eight-day-old account.It's been rumored that Mantle will allowed for unparalleled ease in porting games
all your arguing is fine and dandy, but am i seriously the only one that cares about what game that may be on display?
if you really care about that you would have listened to the presentation. IT is no game, it's just a scenario to test out their engine(though it could at one point develop into a game, it looks like homeworld atm)
actually, i think its going to be starcontrol III or a new Sins of a solar empire as all of the ship artwork came from stardock.

Hmm.

no new hardware, except yes entirely new hardware which is why they need it in future standards including VESA because they can't do it with current hardware. freesync ofc they didn't solve the software side that actually makes it useful for games it's all just pr fluff they threw together in a couple months.oh geez, here comes the master nvidiot PRIME1.
If you actually keep up with thiis stuff, you would know that they arent bringing it to market, because there isnt anything to bring. They are using it as proof on concept to push for the new dp 1.3/eDP/VBI adoption by the OEMs so no new hardware is needed for dynamic refresh.
8M dollars to drive APU sales as a viable mid-end game platform? id say that money well spent.
If they were highly-educated, they probably wouldn't be doing this kind of workYeah, but also "allowed". I think this one's safe.

mantle api is worthless in the same, they'll have to pay developers, which unlike nvidia AMD doesn't do with as much resolve, to use mantle as it's an extra cost as no develop is going to spend money to port a game to mantle for no god dam reason that's extra work that they could use to
improve their directX side of the game for all cards not just a section of AMD cards.
AMD spent $8,000,000 to possibly get better performance in one game long after it was released.
i would love for it to be a new sins, the outdated single threaded engine drives me batty when i cant get more than 20fps zoomed in on my 290 pro.
