AMD's Mantle May Already Be Irrelevant

When AMD (NYSE: AMD  ) first announced its Mantle graphics API, the promise of radically improved performance over Microsoft's (NASDAQ: MSFT  ) DirectX -- the de facto standard in the PC gaming industry -- seemed almost too good to be true. With the first games to support Mantle now available, the API provides large performance gains for certain configurations, but more modest gains otherwise. While Mantle is impressive, it's likely no game changer for AMD.

Source: AMD

The biggest problem with Mantle is that game developers need to add support for the API, a task which adds both cost and time to the development process. Given that Mantle is only supported on AMD GPUs -- not those from rival NVIDIA (NASDAQ: NVDA  ) -- the return on investment for game developers is questionable at best.

Microsoft isn't taking Mantle lying down, with the dominance of DirectX critical to the success of the Windows platform. At the upcoming Game Developers Conference, Microsoft is set to host two presentations that promise to unveil plans to make future versions of DirectX more efficient by reducing overhead, the same feat that AMD has accomplished with Mantle. In addition, a presentation about OpenGL, the other major graphics API, promises to show how the existing implementation can reduce overhead by a factor of 10 or more. With DirectX already widely used by game developers, and OpenGL apparently able to match Mantle's performance gains today, Mantle doesn't seem to have much of a chance of gaining wide acceptance.

A two-horse race
Both DirectX and OpenGL have been around for a long time, and both are very mature graphics APIs. Almost all triple-A PC games use DirectX, and the Xbox One uses a modified version of DirectX that allows for more direct hardware access. OpenGL, on the other hand, is cross-platform, and the embedded version has become the standard on mobile devices. Some high-profile PC games use OpenGL, like the phenomenally successful Minecraft, but DirectX has largely remained the standard in the world of PC gaming.

Where does Mantle fit in? If the performance gains are indeed short-lived, then it doesn't fit in at all. DirectX will take some time to catch up, but OpenGL, at least according to the GDC presentation, is already capable of matching Mantle's performance improvements. And with OpenGL supported by all major graphics hardware vendors and functional on all major platforms, supporting Mantle doesn't make much sense.

What this means for AMD and NVIDIA
Mantle was supposed to provide AMD with a big advantage over NVIDIA's hardware, and while the performance gains are real, they will likely be short-lived. AMD certainly deserves credit for pushing the graphics industry forward, lighting a fire under Microsoft to improve DirectX, but Mantle is extremely unlikely to supplant either DirectX or OpenGL.

This leaves AMD in the same position that it was in before Mantle, spreading itself too thin across multiple businesses and falling behind in all of them. NVIDIA's recently announced GPUs based on the new Maxwell architecture provide massive gains in power efficiency compared to AMD's products, and at the high end of the market, NVIDIA's products offer the best performance per dollar, according to Tom's Hardware.

While Mantle has certainly compelled Microsoft to improve DirectX, I doubt the API will be around five years from now. OpenGL already provides a cross-platform alternative to DirectX while being supported by all graphics vendors, not just AMD, and any performance advantage that Mantle has will be short-lived. If the goal of Mantle was to push the graphics industry forward, then AMD succeeded. But Mantle doesn't give AMD an advantage against NVIDIA, and the latter will likely keep its market-leading position.

    @Timothy Green

    When Mantle is still around 5 years from now will you promise to stop writing?

    Mantle will get better and massively multiplayer game developers are very excited to be able to finally develop epic games.

    DirectX 12 ore whatever will NOT see the light of day for at least a year. And Windows 9 wil probably be the O/S.

    So for MOST of the world you either deal with the innefficiencies of Directx11 or use Mantle.

    DirectX 12 is vaporware. It is nothing but a promise from Microsoft and a dangerous one for Intel as well. The CPU is now the culprit for graphic bottlenecks, Mantle opens that bottleneck and makes better use of the GPU. Intel is ALL about the PRIMACY of the CPU.

    With AMD winning the Console business, one has to assume that any API written either by Sony or Microsoft is very close to Mantle. That also puts Microsoft at a disadvantage XBOX API would also not run on nVidia or Intel GPU's. So they have to dummy down there new version of Direct X and it will as a matter of course perform at a much lower level.

    While Sony and Microsoft have both come out and stated that MAntle suppor twil not be a part of their consoles, neither have they come out and stated that their console API's are proprietaru either. It would stand to reason the API instruction set used by both consoles OEM's belongs to AMD.

    You also don;t really have much of a clue about what drives game development.

    It's ALL about the WOW factor. Mantle gives developers the ability to create games that are staggeringly apic.

    "Build a better mousetrap and the world will beat a path to your door."

    Mantle is a better Mousetrap. If it is not then why is Microsoft announcing software it does not have? They have NEVER pre-announced vapor ware. It also took Intel and nVidia over a year to announce DirectX 11 compatibilty all while AMD was Directx11 compatible.

    Direct 12 will not be available until at least Win8.2 or more likely 9. Given the adoption rate of the software, the eal world impact of directx11 will be miniscule. Since XP and Windows 7 are the two most popular Windows operating system I do not see Microsoft releasing Direct X 12 to run on legacy software. Instead they will use it as a carrot to beat the gaming community over the head to force them to purchase more Microsoft bloat ware.

    MANTLE is available NOW. Nobody is going to wait for empty promises from Microsoft and then have to upgrade their operating system and probably loose their entire installed game portfolio.

    What is errelevant is Direct X 11. It has been rendered obsolete overnight.

    This also shoots holes in Intels plan to give nVidia the boot and go it alone in the graphic space. Intel does not plan on supporting PCIe after 2016. How do I know this? Intle was ordered by the FTC to provide such support until that date. Thsi was in response to Oak Trail NOT having PCIe support.

    Without PCIe nVidia and AMD will not have access to the Intel bus. The ONLY purpose really for PCIe and AGP which is also dead is for discrete graphics cards. Intel expects that it's own IGP will replace most mid-range graphics cards and then they will introduce their own discrete GPU.

    However with the majority of game develoment NOT dependent upon DirectX, this becomes problematic for Intel. Intels plan can not be executed unless Microsoft controls gane development.

    So be careful what you wish for. AMD has been the best friend of the PC consumer by keeping Intel honest and prices low. By crowing about how AMD's latest disruptive technology will be trumped by Microsoft just may not be in the best interest of you or the game enthusiast in general.

    I fail to understand just why the market hates AMD so much maybe it's becasue without AMD we'd all be paying $1000 for a 1 gig single core cpu today.

    Without AMD Intel would not have to innovate and would have a monopoly over the entire industry.

I work with Intel, AMD and NVIDIA and they are all good in their own way, they all have good engineers, but some of the posts on here are so inaccurate that it is embarrassing.

    Mantle is interesting and a throwback to the days or "Metal" and "Glide" (for those of you older enough to remember), but that is not always the right thing to do. Mantle is additional work, not less, so as game developers we have to weigh up what the real return on investment is for, say, an additional six months for a 20 man team and how many copies we sell of a game, over and above what we think we will sell anyway.

    Mantle only works with GCN based products from AMD. Using Steam data as a rough guide, that is maybe 1-2% of the PC installed base of gamers.

    We will keep looking at Mantle and if the installed base increases to a reasonable number (of GCN enabled PC's) then it is something that we may consider implementing.

    Anyway guys, not often that I post on any boards (in fact we are actively encouraged not to), but sometmes, people just have to put the record straight, or at least add real-world input.

    Likely you are not a game developer either.

    Mantle is NOT a throw back to Metal or Glide. And yes it works best with GCN. Why not? AMD has critical mass with the game consoles. The Console API's are all quite likely similar to Mantle and likely were developed by AMD.

    I also did not say that Sony or XBOX API is Mantle they are however similar. But what XBOX and Sony is not is Direct X. The purpose of Mantle is to limit the CPU bottleneck. That was the PURPOSE behind ATI's seduction of AMD and AMD's subsequent acquisition 7 years ago. But if you are a game developer then you kknow all about that.

    DirectX 11 cannot resolve 100,000 AI objects. Just 5000. Directx 11 is obsolete. Unless you right games like Angry Birds or Mario Brothers then Directx is still just fine for you.

    One other thing. Regardless of who I am I will write about what I choose to wite about not what some else says I should or should not write about.

    Engadget just wrote a storey today that repeats exactly what I said earlier about Directx 12 NOT being available for at least a year and if then only probably on Windows 9.

    http://www.engadget.com/2014/03/05/microsoft-teases-directx-...

    "They also say that Microsoft's "close to the metal" lower-level access API is a relatively new project in Redmond, meaning it probably won't muscle in on Mantle's territory until sometime next year. Between that, and the fact that Microsoft has recently taken to limiting Direct X upgrades to Windows upgrades, it's possible that we might not see DirectX 12 in access until we're installing Windows 9."

    A year is a lifetime in Game development. Since Directx 12 is far from release you have 2 choices. Write epic gamaes with Mantle or the same ol same ol medocre games with Directx hoping that you can rewrite it later with Microsofts promises also knowing that the Windows distribution is likely to be pretty poor and the hardware implemetation will be another year away. Pretty uncertain to base your company or your life's work.

    After Microsfot released Directx 11 it took Intel a full year to get Ivy Bridge compatible while AMD had been Direct X 11 compatible from the get go.

    So stop your whining, learn something new and impress us with your game.

    I think you don't really have much of a clue about what drives game development.

    Firstly if you think an average of 10% gains is what is needed to make games "staggeringly apic", you are once again, delusional.

    Furthermore, developing a "staggeringly apic" game for Mantle means that developers are making a game that can only be run on a very small fraction of 18% of the total GPU market. How on earth is that cost effective? They would need to charge well over 100 dollars a game to make their money back.

    If developers make a game that is similar for both Mantle and DirectX, and not "staggeringly apic", it still isn't cost effective. Game developers will not sell more games by making it capable of running Mantle, all of the GCN users are able to play with the DirectX version.

    There is no actual value added for the developers with Mantle. There is cost added however.

    And yes this is true:

    "Obviously if you are going to do DX, then also doing Mantle is additional work. But if you do Mantle first, then you can say doing DX is A LOT more work."

    So lets say that Mantle is 60% easier to code for than DirectX, ignoring all the cost associated with having to learn this new API and finding any psosible bugs with it since it is so new, and that ease of coding is directly proportional to the development cost.

    For the fun of it we will also assume that every AMD GPU is capable of running Mantle.

    By only using Mantle, these developers have cut their TAM BY OVER 80%. For a cost savings of 40%.

    Please use a better argument.

GCN is for all future AMD cards, Steam survey doesn't include selections for all the new AMD cards, so they would probably be classified under other. AMD market share is projected to reach 40% in a few years. Even adoption of CTM D3D will help sell more AMD APUs as it closes the gaming gap with Intel by removing CPU bottlenecks games coming out with DX12.

By the time DX12 comes out, AMD GCN GPUs could be 50% of that STEAM stat. AND the 1-2% is a GUESS, and its likely WRONG still.

    Why don't you shoot for some creativity and find another word.

    Where Mantle romps on Direct X is the 100,000 AI oblects that can be drawn with Mantle.

    The phrase "staggeringly epic" I quoted from the Mantle Video that been on the web for a couple of months.

    For instance the Space simulator genre has just about disappeared as the games want to be more complex; in the words of developers, "epic". With Mantle they can be. With Direct X the developers have maxed out the abilities of the API. DirectX has also managed to keep nVidia and Radeon roughly equal. Mantle disrupts that balance.

    The problem with Direct X is the CPU is a bottleneck. With Mantle the CPU bottleneck is reduced or eliminated and the work is done by the GPU.

    If the CPU load for a game is not high then Mantle will not make that much of a difference. But Mantle really shines when the GPU can carry most of the work load.

    This is NOT want Intel wants to hear.

    Intel does not want to use 3rd party hardware to improve the performance of it's silicon. Which is why Mantle is getting such a hysterical response from Wintel.

    A Mantle upgrade for XBOX is simply new silicon from AMD.

    I think mantle also creates a "console" like environment for devs. something they are used to.

    By basing mantle around GCN, and or if whatever nvidia decides to do, the devs are dealing with sort of a standard architecture, and i think that is more appealing to them, than multiple PC configs with DX. Obviously AMD is in the drivers seat, because they are leveraging/exploiting both platforms. Not to mention the hUMA tech for low-end desktops. This allows low-budget gamers to play AAA titles, while devs can use mantle to squeeze out all the visuals on those low-end rigs. its a win win for AMD right now.

    It seems to me that DX has become more about brute-force, ie. if you want decent frames with all the bells and whistles then you need to upgrade your pc, and the OS too. While Mantle is more about giving developers the tools to push the graphics envelope in a longer hardware cycle. Now the performance is in their hands, and some PC only devs would rather pump out the game, and let the end user worry about how it plays.

    Charlie Dermajian is not often wrong.

    Developing Mantle would be an asset only if AMD could gain a critical mass, if you will, of game developers. That is why the console wins where a necessity almost at any cost, or certainly at reduced margins.

    I can remember when folks rolled their eyes when AMD commented that XBOX would have Avatar-like graphics. Well with Mantle or a low level API they will.

    This also scares the bejeazous out of Intel who is all about maintaining the primacy of the CPU which is becoming the bottleneck for high performance graphics. This was also predicted by ATI in 2006 and is the concept behind how ATI seduced AMD into acquiring them and why AMD pioneered the APU. Mantle also eliminates the mid price point market for discrete graphics cards. The majority of the gaming market is not bleeding edge enthusiasts but rather those folks would would rather pay $80 for an APU from AMD that can compete easily with a Intel/NVidia pairing costing several times that. Intel HD graphics are a non-competitive joke and aren't even a consideration. This is probably the source of the rumour that NVidia may retreat from consumer graphics silicon entirely.

    Hence the end of DirectX; now Intel will not have Microsoft to create the great equalizer called DirectX. And for Microsoft to make XBOX competitive they are going to have to adopt Mantle or suffer the consequences. Hence DirectX12 = Mantle. Why else would AMD already announce support for an API that doesn't exist yet?

    "AMD Demonstrates Full Support for DirectX 12 at Game Developer Conference

    Today, AMD announced support for Microsoft and its revamped graphics application programming interface, DirectX 12, a new "console-like" version of the graphics API that has inspired PC gaming for nearly two decades. During the Microsoft-sponsored panel, DirectX: Evolving Microsoft's Graphics Platform, AMD revealed that it will support DirectX 12 on all AMD Radeon GPUs that feature the Graphics Core Next (GCN) architecture."

    http://bit.ly/1r32OtR

    Clearly DirectX 12 is Mantle that is dummied down to be compatible with NVidia GPU. Of course AMD had fully supported Direct X 11 almost a year before Intel or NVidia.

    The gaming industry is all about the visual experience as well as a great story. A good story that looks bad will not sell.

    The old fighter pilot adage comes to mind here; "he'd rather die looking good than live looking bad."

    The game developers are going to line up behind Mantle as they can not afford not too.
