AMD Mantle update...

[blindbox]

I'm more looking forward to the starswarm demo. Great news that Mantle is confirmed January, but there's no point if I can't test it as I don't have BF4.

The february info is fake, they delayed it until may

I'm pretty sure he can produce bull on that level without inspiration or external help.

He forgot to mention 2015... may 2015.

today or tomorrow most likely

10% improvement according to AMD. on the above link. When all the top-end cards are a few percent away from each other, this matters a lot.

So R9 290 = GTX 780 Ti for BF4.

StarSwarm demo in 10~12 hours, yesssss!

EDIT: Nooo AMD why did you do this... no support for GCN 1.0 cards yet (get google translate, I don't speak french either). http://www.hardware.fr/news/13551/am...h-bf4-10h.html

Sounds like we are only hours away from the Drivers. Now we need Dice to release the Mantle patch for BF4.

Well, Battlefield is doing an update right now. Maybe they are rolling out the patch now with the update. Will see if I can find some release notes. 1.23Gb patch

Mantle patch has been released

http://battlelog.battlefield.com/bf4/news/

The new game update for Battlefield 4 brings the Mantle renderer that DICE has developed in conjunction with AMD. With this first release of Mantle, you can expect performance increases in the game if you have the hardware to support it. In this blog post, the Technical Director for Frostbite details this exciting new step for the Battlefield series.

Hi,

My name is Johan Andersson and I’m one of the Technical Directors in the Frostbite team and I have something very exciting to share with all Battlefield players: the latest Battlefield 4 update on PC includes the long-awaited new renderer in Frostbite that is using AMD’s Mantle.

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.

Battlefield 4 on PC is already quite heavily optimized using DirectX 11 and DirectX 11.1, but with Mantle we are able to go even further: we’ve significantly reduced CPU cost in our rendering, efficiently parallelized it over multiple CPU cores and reduced overhead in many areas.

The biggest performance gains can be seen when the game is bottlenecked by the CPU which can be quite common even on high-end machines and this was main goal to improve on with Mantle. We’ve also been able to streamline and optimize some of the GPU workload. The end result is that game performance is improved in virtually all scenarios in Battlefield 4 on both Windows 7 and Windows 8 when running with Mantle!

This update is the first release of our new Mantle renderer, and we will continue to provide more tuning for different types of configurations in future updates. Still, we are really happy with the performance improvements that we are seeing with this update and we believe you will be as well.

[MaddMuppet]

Up to 58% with a high end 6 core Intel and 2x290x's. Wow, pretty sweet.

Now come on AMD, release the 14.1 drivers, pretty please.

Performance tests

To compare performance with Mantle vs DX11 we in Frostbite have done a couple of benchmarks with Battlefield 4 on 3 different configurations & test scenes:

Test case 1: Low-end single-player
CPU/GPU: AMD A10-7850K (‘Kaveri’ APU), 4 cores @ 3.7 GHz
Settings: 720p MEDIUM settings.
OS: Windows 7 64-bit
Level: Singapore “Beach”
This area is heavy on the CPU as it is quite a lot of action going on, but the game is primarily GPU-bound both on DX and with Mantle but thanks to GPU optimizations with Mantle we get a good performance improvement.
Result: 26.6 ms/f -> 23.3 ms/f = 14% faster

Test case 2: Standard 64-player multiplayer
CPU: AMD FX-8350, 8 cores @ 4 GHz
GPU: AMD Radeon 7970 3 GB (AMD will add support for the AMD Radeon™ HD 7970 in a later stage of Mantle’s release schedule, learn more)
Settings: 1080p ULTRA 1x MSAA
OS: Windows 8 64-bit
Level: Siege of Shanghai
Level was tested with 64 “pseudo players” that we have for our own internal testing that simulates heavy game workload that we have in multiplayer in order to get more deterministic results compared to full real multiplayer. 64 players on the large Battlefield levels is really demanding of the CPU so this test case is primarily CPU-bound.
Result: 18.87 ms/f -> 15.08 ms/f = 25.1% faster

Test case 3: High-end single-player with multiple GPUs
CPU: Intel Core i7-3970x Extreme, 12 logical cores @ 3.5 GHz
GPU: 2x AMD Radeon R9 290x 4 GB
Settings: 1080p ULTRA 4x MSAA
OS: Windows 8 64-bit
Level: South China Sea “Broken Flight Deck”
This single-player scene is heavy on both the CPU and GPU with lots of action going on. Test was done on the highest end Intel CPU on Windows 8, which is the fastest option before Mantle thanks to DirectX 11.1. Still this CPU is not fast enough to keep the 2 290x GPUs fed at 1080p on Ultra settings so we get a significant CPU performance bottleneck which results in major performance improvement when enabling Mantle.
Result: 13.24 ms/f -> = 8.38 ms/f = 58% faster

I find this first test kinda funny.

It shows that the majority of the people out there won't reap any noteworthy benefits from mantel at all. You need a high end gaming rig to actually see the real benefits.

Anyway gona wait for some more in depth reviews from unbaised sites. Call me paranoid, but I dont take this numbers from an engine engineer without a grain of salt.

[kuroikenshi]

on battlefield, and right now... yes
later all GNC tech will benefit from it a lot more so long we stop complaining and let the devs do their work.

Perfs looks good.




bad news for gcn 1.0

And very bad news for nvidia

Wat?
15-25% on low-mid en rigs isnt "noteworthy" ? Cmon dude, dont be a hater.

Real benefits on high end gaming rigs? Glad I'm on xtremesystems then

from 38 to 43 is nothing worth mentioning, thats exactly what you get in low end situations. percentages always seem "nice" absolute numbers are not. This numbers are also SP only (who buys BF for SP anyway?)
Wouldn't be surprised when you get even larger percentages in MP, but that means nothing when you have avrg fps of 32 in MP and get a 20% performance increase to 37fps.

Thats why i hate all this marketing stuff... oh look we have 300% incrase on our low end product (increase from 3 fps to 9 fps which isn't mentioned).

If you look at all the powerpoint slides from the past, amd created the hype and implyed you will gain most benefits from there APUs and low end gaming... now with first nubmers it turns out not to be true, if anything its teh exact opposite and if you want best performance you have to pay for it.

[thematrixhazune]

Still doesn't deny the fact that is free improvement no matter if its 1% or 300%.

??? I thought the slides said CPU-bound things would get the most improvement. Generally when I think CPU-bound I think high-end GPU(s)...

AMD is clarifying that the patch supports all GCN cards but not all optimizations are there for GCN 1.0

I dont get exactly what youre saying, however changes like 23 to 27FPS CAN be REALLY noticable.It can be the difference between jerk now and then and no jerk at all.
I dont play MP games at all, so dont be so close minded about that, however most important thing is, its not about BF4, its about all future mantle powered titles!
And those slides about APU`s and AMD cpus in general are true, you just have to have settings that are CPU bound, and thats not hard with AMD CPU`s :P .
I REALLY dont get ANY negativity towards this, thats FREE PERFORMANCE OUT OF OPTIMIZATION, thing long forgotten in PC world, and it will be something to consider when buying a new GPU AND CPU.
One pretty important scenario to consider is , IF mantle somewhat takes off, AMD CPUS are still going to be "on the table" when putting a new gaming PC, whenever money is gonna be tight that is of course.Without that its hard to recommend AMD CPU, but a cheap ass Kaveri derivative with its GPU turned OFF and a decent GPU to go along with it in mantle enabled games are going to be alright,and thats a scenario that will probably get almost the highest boost, alongside powerful crossfired machines.Thats a WIN-OK-WIN ,for free.

On a side note, i have a Mediocre gaming CPU, so its not that hard with 290X or something along these lines to be somewhat CPU bound, with mantle around, next time i buy GPU its gonna be harder for the green side to convince me and people like me to buy theirs instead of the red ones.
