The AMD Mantle Thread

Son, I am disappoint.

While the averages for that Kaveri test case have changed by "only" 14%, the frametime graph looks fantastic! It's ridiculously flat now, better than any of the others. That's a console level of consistency.

+1 So many people concerned about maximum frames. Look at the consistency! Much more important.

Hawaii (R9-290/R9-290X), Bonaire (R7-260) and Kaveri are all GCN 1.1 and support TrueAudio so the feature set is different. I imagine DICE did not make BF4 Mantle dependent on TrueAudio as that would be stupid. But since GCN 1.0 in the form of R9-270/R9-280 are still a major part of Radeon sales, getting support for them must be a priority. And the initial beta release has CF problems but they are obviously working on that too since they mention IB-E + 2x 290X results.

In fact, getting high-end CPU plus CF working would a major showcase features especially in forums where high-end results (money-no-object) rigs do get blown out of all proportions to their actual marketshare. If the can show that an IB-E plus 3-4 290X makes an monster BF4 rig I'm sure it would receive major coverage in forums. There's a reason Nvidia are so keen to have the performance crown even if their highest SKU only sells in modest quantities.

I would imagine that AMD's driver team is very busy ATM. The Eyefinity framepacing fix for GCN 1.0 did just get released with this driver - just hope that GCN 1.0 Mantle support doesn't take that long.

Congrats father. Enjoy your low min fps then, when i frag on with consistently good performance. S m ooth nes s in dx.

Mantle is a new low-level graphics API that we’ve been working very closely with AMD on over the last 2 years and it is a major change & improvement to how we are able to program & use modern GPUs in order to get the most out of them.

So, about the two month time frame for Mantle support. As far as I can see it, the performance increase for GPU limited scenarios is disappointing, and many GPUs aren't supported. Who's to blame for that? Does it take two months of development for Mantle on a per GPU basis? Two month development for crossfire? Or is this AMD's driver team?

Sorry, I can't see how anyone is going to spin a 2-10% gain for GPU limited scenarios as being what everyone expected. SKYMTL at hardwarecanucks mentions that the expected gain for someone with a high end CPU, who will obviously be GPU limited, is 0-5% while using Mantle on a 290/290X. That, to me, isn't what AMD relayed in their marketing presentations for the 290 / 290X.

 

[ShintaiDK]

There is essentially no GPU benefit at all. Its CPU only as expected. It was all about the API, nothing else.

And it leaves the question about the lacking parts in AMDs DX driver. FX chips already perform better with nVidia cards than AMD for the same reason.

You run a Gigabyte GTX 780 (Stock) w/ XSPC Full Cover Water block.

Would anything have impressed you?
I don't think you are part of the target audience.

 

[el etro]

Who here expected more 200 fps on a 4960x with 2x290x??

Why mantle is a disappointment?

 

[Genx87]

Is this GCN 1.1 vs 1.0 a result of being closer to the metal? Meaning when GCN 1.2 or 2.0 comes out they will need to add support for a 3rd GCN arch? If this is the case where does the implentation need to occur? Driver level or game engine level?

AMD's marketing for Mantle tied in with the 290 and 290X cards and nobody is using that mess with a freakin' i3, celeron or Pentium. Nobody buys a 500-700$ GPU to pair with a 50-80$ CPU. Please.

The target audience wasn't expected to be cheap bargain bin CPUs. Nobody expected that. Everyone did expect huge gains with their high end PCs with 290 and 290X cards. And that isn't happening apparently.

Johan Andersson @repi 3 Std.

@BitCoinBoy no it is an important case and 7970 will be supported in the AMD drivers. it is supported in the drivers we have

Dice already has working gcn 1.0 drivers. cant be that long until release.

Can you show me a post where you stated that you expected any huge gains?

That's fine, I'll enjoy my negligible 50% boost when my dual 290s and stock 4770k

 

[HurleyBird]

Performance gains range from low to extraordinary, depending on configuration. What's more impressive is how consistent the frame rate is. Look at the green line (GPU) on the multiplayer test case. It's basically a straight line! Somehow, the GPU frame time increased more than the CPU frame time in the multiplayer case, and with Mantle the scenario is incredibly CPU bound.

 

[Unoid]

Some of these comments that are negative make me scratch my head. Too many ego's justifying their nvidia purchase.

6 core intel + crossfire 290x's went from 79 fps to 121fps and you're complaining?
Looks like Mantle is a success, even if it is 5-10% it would have been successful. I use 680's in SLI and cna't benefit, but I don't mind pointing out an obvious benefit when I see one, take note some of you.

wow, reminds me of hitlary clinton or some other liberal ignoring facts and complaining about some other issue altogether.

But people do pair older CPUs with better cards or even go SLi/CF. The amount of life breathed into older Q2Q, X6, 1st gen i7 and current AMD CPUs is massive. Someone that ran out of GPU upgrades is able to upgrade again.

I'd wait for Mantle reviews but the 58% performance increase with a 3970k + 2x 290X combo is quite something.

 

[B-Riz]

So the greater installed base of 7950 / 7970 is shafted vs the lesser installed base 290 / 290x users because the 290 / 290x gets drivers first???

Might buy an nVidia flavor...

But buy an nvidia card then you definitely will get mantle

Plz if u dont know anything than dont brother to post .AMD said that R9 290X will huge amount of performance gain over titan and same was said by Roy@AMD.So dont go there and u will get more disappointments like others.

 

[spinejam]

No "fanboy" here, just excited to see this finally arrive. For all of us who've been around the block - you know, now that AMD has shown it's hand, Nvidia will pull somthing out of their arse to steal some thunder. It's all good though --- keeps advancing the tech to benefit us all.

Especially because it would be bottlenecked.
If a $100 CPU is all I require to have a $500 GPU achieve its potential, why wouldn't I pair them?

Did you not read Dices post? It really sounds like you ignored it.

Getting a 58% boost when using a i7-3970X with SLI 290X's is not a big enough jump for you?

And not sure who you mean when you say "everybody". AMD has been saying since early on that this is a CPU related performance boost. The slower your CPU is, the bigger the boost. Unless you have multiple GPU's, then even the highest end CPU's get a boost.

 

[parvadomus]

So, 2,4% more performance in gpu-limited situations.

What a game changer.

And what did you expect? If the GPU is fully maxed at a given time, an API wouldnt magically add more compute power. Or you expected it to emulate more shaders and GPU resources or something? I expect it to remove CPU bound minimums, and that is a win.
In the end your poor trolling attempts only reflects your almost zero computer knowledge. :whiste:

Thank you, this is the exact situation im in... people seem to think along the lines of building a new PC but not everyone is in the same boat

i have an older i7 920 and went out and got a 290x to play BF4, i didn't feel like building a whole new PC for one game and i bet im not alone
