Spidre, we are disagreeing here because you don't think that they already have it up and running while it is my contention that they in fact do. APU13 is already in full effect and the December BF4 Mantle update is not that far away; do you think they would make a presentation about Mantle tomorrow and say, "Oh, we didn't actually test Mantle using a gaming setup. However, according to our math, Mantle provides up to X% improvement... buuuuuuut, we didn't test it to find out. P.S. Please believe in us. Mantle will rock your socks"?

Or later this month ...

http://www.hardwareluxx.com/index.p...ield-4-mantle-update-expected-this-month.html

In the Twitter conversation, the question was asked at what point the public can expect the first benchmarks of the new Mantle API. In response, Andersson announced:
Johan Andersson, technical director, DICE:
likely slightly before we ship it in November, when all of our work and optimizations are done.

"Eidos-Montreal are behind many big name games titles including Thief, due in February 2014, and the AMD Gaming Evolved title Deus Ex: Human Revolution. David Anfossi, studio head at Eidos-Montréal said “Mantle lets you use AMD Radeon GPUs the way they are meant to be used, unlocking many new opportunities and increased CPU and GPU performance.” Anfossi concluded that “Mantle is one of the most important changes to PC graphics in many years.”

Wonder what JHH is thinking watching this develop.

Kaveri would logically be the Mantle performance demon able to take full advantage of the PS4's HSA/hUMA/APU optimizations. I expect at least a 50% performance gain in Mantle vs. non-Mantle mode.

Next up I would guess is GCN 2.0 GPUs + FX CPUs.

Bring up the rear GCN 1.0 GPUs and Phenom CPUs.

xfire scaling with mantle?

Like some people have posted, I'd imagine that CrossFire scales better with Mantle because the bottleneck tends to shift to the CPU when you have that much GPU power. Mantle is supposed to alleviate CPU bottlenecks and allow the full power of the GPU to be used, which in theory should push the bottleneck back to the GPUs, thus helping with scaling as you are now utilizing your GPUs more effectively.

I haven't posted a lot, but I would like to take a guess aswell: 30%.
But like others have posted, it'll depend on the used hardware, so there will be variations in performance.

I'm also very curious about the new effects which could be accomplished through Mantle, not just the extra speed. The extra speed gained through mantle should be related to these new effects, the extra Mantle performance will be needed for the effects I guess.
In some way like PhysX adding effects, but without the performance hit because of the extra performance gained through Mantle.

Updated:

Assuming we will get results in the form of a bar chart across various games, we have the following estimates guesstimates for what Johan specifically will show us as the average improvement using whatever bench and settings he has:

0 - 4.99%: 0
5 - 9.99%: 0
10 - 14.99%: 0
15 - 19.99%: 0
20 - 24.99%: 3
25 - 29.99%: 0
30 - 34.99%: 3
35 - 39.99%: 1
40 - 44.99%: 0
45 - 49.99%: 0
50 - 54.99%: 2

It's going to be difficult to get apples to apples comparisons, as while Mantle could certainly be used to increase raw frame-rate, especially in cpu limited situations, many devs will take advantage of the ability to increase draw calls on Mantle in order to improve visuals instead of fps.

Remember they have to create a game that runs on DX11 so it has to be able to reach a certain minimum performance - it's not like they will start attempting 20K draw calls on the DX11 path just so we can get an apples to apples comparison with Mantle. If they did there would be cases where Mantle was up to 10x faster, but they aren't going to do that.

Tbh, I'd be very happy if they could get hit 60 FPS minimums across a wide range of scenarios and then put the rest of the performance benefit towards visuals. Enforcing a FPS cap at that point would essentially give us buttery smooth visuals in line with the same degree of smoothness consoles generally provide.

Here's my guestimation.

Ehhh... I'll take that as a 23.4%.

A week ago there were still so many people dissing Mantle, saying it won't be widespread and only used by DICE because AMD paid them $$..

Then Activision announced Mantle support... Crytek said the same... then Square Enix said they are going to use Mantle in their engine.. a few more devs announce, and finally, Unreal Engine is getting Mantle.

Looks to me like EXACTLY what some of us have said a long time ago. It's simply devs catering to the masses, and the console generation belongs to AMD for the next 8 years or so, they ARE THE MASSES. Developers need to chase after every bit of performance they can get, to squeeze out great looking games because the competition is so intense to make your game stand out amongst the crowd. Not using a low level API that targets essentially the SAME hardware across multiple platform is insanity .

yeah, I think we can lay to rest the objection that nobody is going to use it. Even a PC only game like Star Citizen is going to use it. It shows that Devs do care about performance and quality.

Agreed, it's essentially the bandwagon effect. Once a critical mass of developers adopt Mantle, the developers who don't end up using it begin losing out. On that note, it seems that critical mass has been reached already.

Yep like I mentioned here they are all falling in now, it's only a matter of time. - http://forums.anandtech.com/showpost.php?p=35536428&postcount=1125

I thought about it a bit more and in some cases Mantle actually makes it easier because there is much less faffing about trying to limit draw calls for performance. Even lazy coders can benefit from it.

It won't make things easier in that regard, as they still have to do that for their DX code path.

We may see a lot of people take a crack at it for a round, but afterwards, we'll see how it actually benefits, or hurts games, and the 2nd round of engine/games will be more telling on how good it actually is. I doubt the first round of games will go as smooth as they'd hope. It never does.

Wow Hyping this API with non sense.Here people hyping this API so much do they even now that fact if people want Mantle fully performance gain than u must API and AMD GPU combination .All most all anandtech member have intel cpu and i not seeing that they are shifting to APU very soon even if it gives 20% boost.

Uhh, what does having an Intel CPU matter? Also you keep pulling nonsense market share numbers out of thin air as if that was all it was going to take to prevent adoption, yet all the time more and more devs are signing on to Mantle. Something isn't adding up.

Still u dont get though.U are hyping so much which is not even out yet.In there Slide show they state clearly it will be APU and GCN combination to gain Mantle full performance not intel and AMD combination but of course u will gain some performance through mantle because of having AMD gpu.

If u have some knowledge than go there forums and read what they clearly state.
U are hyping so much which u even dont now what is which called non sense.People like u were saying Xbox will use mantle but they proved u wrong and u also said Dx will die soon but Mantle is using Dx and than again u proved to be wrong so dont make any prediction of any thing which u dont now.

This is low level coding for GCN. It has nothing to do with what CPU you have.

Mantle only benefits users with GCN-based graphics. It should be impartial to your choice of CPU. As a matter of fact, I suspect Intel CPUs might be able to take advantage of Mantle more so than AMD CPUs because Intel CPUs have higher single-core performance, so in theory you can extract more CPU performance through the low-overhead API while its AMD brethren starts to run out of steam sooner...

let see though.They will explain what is it soon enough .

So you're basically saying you don't have a clue, wait for their explanations.. but all this time, you and your ilk have been here bashing Mantle endlessly.

That about right?

It needs to be said again and again because CLEARLY, some of you don't get it: We have no evidence to support the case that Mantle will fail. In fact, we have plenty of evidence against that notion, with so many developers going with it and major game engines incorporating it.

Link where I said xbox will use Mantle. Mantle is not using Dx. Where are you getting this stuff from? Do yourself and everybody else a favour and stop reading it.

This my troll post . Lets hope mantle give at 10% increase or more and mop the floor with nvidia . Also vice versa with nvidia. I like to see competition and I loathe when one company always has the top spot. Lets get it AMD the under dog.
