The AMD Mantle Thread

[Enigmoid]

Not at all. BF4 is by far the most CPU hungry game I have ever played (Talking multi-player here, 64 man servers). Like I mentioned above, my CPU sits at 95% utilization (average, it hits 100% at times). Even a 4.5Ghz 2500K will sit at 80-90% CPU.

Thats why mantle has less of an effect on faster CPU's.

The question was primarily rhetorical but I stated it to show the BS AMD is trying to pull. (The CPU usage is irrelevant, I was asking about fps @ ultra).

FX 4300 @ 3.8 = 56 fps.

A10-7850k + DX = 38 fps, a10-7850k + mantle = 55 fps.

CPU wise FX 4300 ~ a10-7850k

Something doesn't look right.

If by # of objects, you mean like explosion fragments and what not, or other trivial stuff, yeah. That would be like PhysX stuff. If you mean more units on an RTS game, that would change the game, and simply wouldn't work.

I did say base physics btw. If you think the baseline physics will be changeable, that would prevent multiplayer. If you mean like flowing capes, that would be what I meant by PhysX like sparkle.

I don't see Swarm demo like objects in a real game, as those things can't simply be removed and be the same game.

Yes I was talking like # of trees, decals, or amount of random objects. Things that improve immersiveness, but have nothing to do with core gameplay mechanics. In single player they can do whatever they want though.

Isn't that 45% using directx 11.1 in Windows 8.1?

No, that 45% is using Mantle in Windows 8.1 not DirectX / OpenGL.

What about the guys using Win 7 which has been
Shown to show less performance than Win 8.
I'm hoping to get better performance in Win 7 with Mantle.

I am also hoping the Mantle performance enhancements are the same across Vista, Windows 7, Windows 8 and Windows 8.1.

Obviously you can only get DirectX 11.2 on Windows 8.1 but Mantle should work across all modern Windows OS.

In that respect, yeah, Mantle could add that sort of thing, and I wouldn't be a bit surprised.

According to this Australian, Mantle hits tomorrow.

Big news for AMD users - Mantle will be released tomorrow, along with the BF4 patch. Just as I go on holidays..

AMD claims it'll bring a 13% overall improvement to users running BF4 Ultra settings at 1080p. Not quite the huge leap we were expecting.

The bad news is Mantle can cause stuttering and stability issues in BF4 for CrossFire users. Also only seems to benefit R9 290 series atm.

Got the announcement via an email from AMD.

 

[Venomous]

So 38 fps for kaveri a10-7850k on ultra? Does that seem really low to anyone?

Keep on mind, were a minority building ultra performance pc's. A lot of people simply goto a store a buy pre built pc's with a ballpark cost, not an actual performance value. Later on the owner decides to add a 3d card to the mix because his gaming experience sucks , but has no idea that he most likely bottlenecked his system. I think mantle fixes these issues...

FX 4300 @ 3.8 = 56 fps.

A10-7850k + DX = 38 fps, a10-7850k + mantle = 55 fps.

CPU wise FX 4300 ~ a10-7850k

Something doesn't look right.

Interestingly, on another of their benchmarks, the I7-3970 matched with the Titan only gets 66 FPS. That's much lower than the I7/Titan combo in your example(119)

He says he got an email from AMD, but also says a number of negatives.
I wonder how that works? AMD sent him an email announcement, and
"oh by the way", it has this problem, and doesn't really work on most GCN cards, and the performance improvement is only 12%.
But who am I to doubt him?

 

[Paul98]

I will believe nothing about mantle and BF4 til I see results for myself.

 

[desprado]

I think if mantle dont release this month than we should close this hype until mantle get released.

 

[DiogoDX]

13% is a OK boost (not great) for high end systems in a game that was just patched. For future games I hope to see some stuff like better effects and physics build with mantle in mind.

Exactly. If the benefit isn't huge in BF4 with a high end system, I don't care really. They can make new games with intense CPU needs that will only be viable when using Mantle. Sounds good right? Too bad I don't think it will actually happen. I am totally skeptical at this point.

Only reason I can think of for the discrepancy is the higher numbers are from singler player, and the lower numbers AMD showed are from multiplayer.

For instance I get a solid 60fps through the whole campaign, no issues. But on 64 player servers I drop into the 30's. Not because of GPU usage, but because of CPU usage.

Is mantle supposed to do anything in way of effects advances or image quality in games? The gpu performance bump is one thing, but graphical fidelity is another.

Performance and image quality are equivalent. When you increase performance, that allows for higher image quality.

If I remember correctly, they mentioned in oxide interviews that because of Mantle they were able to add more effects because they weren't as performance punishing as before or limited.

Not sure if BF4 will get any noticeable graphicial fidelity boost. Have they mentioned it?

PCper posted a Catalyst 14.1 overview, including some mantle performance numbers with BF4 which were provided for them by AMD.

May cause stutering with crossfire? I have cpu spikes aka makes the game stutter already even if I use a single GPU or dual 290x, it makes no difference. Maybe the Mantle and BF4 patch will fix BF4 for me? I can only hope.

 

[Midwayman]

Plenty of games got physX support. Mantle could be free performance to throw at stuff like that.

For the Oxide demo

CPU-limited scenario: 319% (1080p) and 281% (1600p) performance improvement in the “RTS” test on Extreme settings with the AMD A10-7700K and an AMD Radeon R9 290X.
GPU-limited scenario: 5.1% (1080p) and 16.7% (1600p) performance improvement in the “RTS” test on Extreme settings with the Core i7-4960X and an AMD Radeon R7 260X
Average uplift for 1080p: 115.65% (Average of 290X and 260X data on the i7-4960X, A10-7700K, FX 8350 and i5-4670K)
Average uplift for 1600p: 75.19% (Average of 290X and 260X data on the i7-4960X, A10-7700K, FX 8350 and i5-4670K)

Slower cpus are going to love this.

[DamnedLife]

WOW get ready!

 

[Arkadrel]

Battlefield 4:

For people with insanely strong CPUs and really weak GPUs = ~2% perf. gain.
(ei: Core i7-4960X + Radeon R7 260X)

For people wiht insanely strong GPUs and really weak CPUs = ~41% perf. gain.
(ei: AMD A10-7700K with an AMD Radeon R9 290X)

From: http://techgage.com

AMD stresses that it’ll be a true beta, and that performance will no doubt be enhanced over time, as well as launch bugs (such as the inability to take advantage of Mantle in a multi-GPU setup) prevalent.

Lol doesnt work with Crossfire yet huh? <.< oh well, atleast their still working on this.

This will mostly help people with weak CPUs, ei Phenom II users ect, or older Intel CPUs.
I actually think their are alot of people that ll probably see 20%+ increase from useing Mantle.
