DirectX 11 vs. DirectX 12 oversimplified

DirectX 12 won’t make your PC or XBox One magically faster.

First off, the developer has to write their game so that they’re interacting with the GPU through multiple cores simultaneously. Most games, even today, are still written so that only 1 core is dedicated to interacting with the GPU.

Second, this only benefits you if your game is CPU bound. Most games are. In fact, I’m not sure I’ve ever seen a modern Nvidia card get GPU bound (if anyone can think of an example, please leave it in the comments).

Third, if you’re a XBox One fan, don’t assume this will give the XBO superiority. By the time games come out that use this, you can be assured that Sony will have an answer.

An interesting read

We all know games just get better and better as the developers better utilize their tools.

Can't wait to see what developers will bring us next

GameNameFame4135d ago (Edited 4135d ago )

I am sure dx12 will improve x1, but over simplifying. Dx12 gives what consoles have to PC. Code to metal or close to it.

Even MS themselves said it won't help X1 much. Why are we still desperately to grasp on to this? X1 is a good console on its own right. Just accept its limitations.

"First off, the developer has to write their game so that they’re interacting with the GPU through multiple cores simultaneously"

Yes. Same goes for PC and PS4. There is already middle ware devs use for that. That is not proof that "x1" is designed for DX12. That is just desperate nonsense...

Even MS went out of their way to say this won't do much for x1.
http://xboxonedaily.com/201...

http://www.dualshockers.com...

Even their slides say many dx12 stuff is already on x1 and dx12 is giving what x1 has to PC.....

Bladesfist4135d ago (Edited 4135d ago )

That is actually BS. You can't / shouldn't talk to an API from multiple cores if it is not built to be thread safe. You will have a whole lot of crazy happen and your game will most likely be unstable. In fact it is plain impossible before DX 12. No idea about Open GL or Sony's graphics API though the developer hinted that they would try and catch up to these changes.

"Every time I hear someone say “but X allows you to get close to the hardware” I want to shake them. None of this has to do with getting close to the hardware. It’s all about the cores. Getting “closer” to the hardware is relatively meaningless at this point. It’s almost as bad as those people who think we should be injecting assembly language into our source code. We’re way beyond that."

Kal0psia4134d ago (Edited 4134d ago )

@GameFame

Did you not read the article in where he emphasizes it's not just about coding to the metal, or did you skip the article and went straight to commenting?? All of those Phil Spencre response you post are very specific to questions asked. Will it improve hardware? ...No!

Now that is taken into consideration, Brad Wardell's points has nothing to do with improving hardware. He is not speaking of some hocus pocus technology that will boost hardware specs. That is YOUR adamant behavior going into these articles spreading your rinse and repeat garbage. This has alot to do with developer tools implementations, software that allow developers to do more. And more on a hardware desgined for it. XOne is riding on a gimped API with updated versions to mimmick Dx12, if we're going by the recent SDK leaks.

So what's desperate nonsense here is you wasting your time proving nothing. These are developers developing the game and they're touting for it. It's goign to be innovative at least mostly for PC, or in other word from another developer a "Paradigm Shift" for game development overall. So of course many of the slides state that Dx12 "feauture sets" is already on XOne, but going by the SDK leak, they were demos.

So there is reason subject keeps being brought up, XOne was a custom designed chip. PS4 was a straight forward design with a single pool of memory. Nothing more or less than that.

marlinfan104134d ago

Phil spencer retweeted this article so that's saying something right there

Azzanation4134d ago (Edited 4134d ago )

Games are CPU bound, DX12 is for CPU bound games. Why is it so hard for you to understand. First of all Xbox fans arent claiming anything, PS fans are the ones downplaying it because there beloved system wont be getting a API software update.

If your going to troll do it right.

4134d ago
Volkama4134d ago

@N4gamingm The vast majority of the 5billion transistors on the SoC are the ESRAM. It doesn't mean the XBox One is anywhere close to comparible to a 5billion transistor GPU.

BG115794134d ago

I don't know why are people arguing about this. When DX12 comes out, if the gains are that spectacular it will be very easy to see the difference.
When is DX12 coming out already?

GameNameFame4134d ago (Edited 4134d ago )

You guys are delusional if you don't think there is multi threading on x1 now.

You think devs been seriously just been using 1 core for real?

@azznation

X1 is gpu bound more. Look at sub 1080p. That's proven.

And w.e minor updates on dx12 always go to ps4. Just look at dx11.

@kalopsia

Loblolly lol. You do realize CPU cores and gpu cores are identical on ps4 and x1. Ps4 just have more cores.

You do know that right? There is no such thing as x1 secret super sauce. You can't be that desperate to delude your self.

Kal0psia4134d ago (Edited 4134d ago )

^^^

Point out clearly where I denied PS4 or XOne and it's cores?! Exactly, creating your own self-deluded arguments.

Nothing is "secret sauce" apparently that is true, because the leak has proven at least most of that secret sauce is true. Of course developers use multiple cores, but NONE as stated in the article is being used "simultaneously", becuase it's still Dx11. Keyword simultaneously.

Nothing hardware wise is specificaly GPU or CPU bound, that's developers choice in game design. You clearly have NO clue what your commenting on. It's kinda funny in how much you are in these technical articles yet completely lack the understanding of any of it. You actually think peopel consider your points over the "DEVELOEPRS"?! ...No! Grasping straws?! Yes you're down to your last straw buddy. You're deulsional. xDDD

GameNameFame4134d ago (Edited 4134d ago )

You do realize you are the one yammering about how x1 is custom when ps4 is off the shelf. When ps4 is the one with hidden secondary CPU, hUMA using unified architecture using gddr5, when x1 opted out for cheaper and weaker alternative that Sony considered and passed on.

Lol. Tell me what secret sauces are confirmed. Loll lol. Please. That it can do multithreaded calcs ? Lololololololoool. That's secret sauce? Seriously? Ps4 and wii U can do it too. Sony devs even discussed implementing it like year ago on infamous.

And yes x1 is GPU bound in many many games. If you ignore devs, it is obvious given past games and seeing where it is lacking.

It is just pathetic you desperately hoping on secret sauce. Especially one MS shot down themselves. Even MS devs own slides only talk about PC when talking about dx12 benefits. Hahaha.

Seriously you thought multi threading meant taking turns? Not simultaneous? Lol so each core takes turns and break and do nothing? Loll lol.

Just goes to show you are desperate enough to believe anything.

Herd is real info from the actual devs who actually programs.not some guy who haven't done it in decade.

Oh N4G, you have really lost your way, haven't you?

HeMan764135d ago

"First off, the developer has to write their game so that they’re interacting with the GPU through multiple cores simultaneously"

This is definitive proof of the XO's hardware structure simply designed for DX12 because recently,the leaked documents displayed us that the the XO has 8 gfx contexts to interacting the CPU with the GPU similtaneously.

" Most games, even today, are still written so that only 1 core is dedicated to interacting with the GPU."

This simply proves why XO games came out with lower res.because the hardware had restrictions due to API.

"Second, this only benefits you if your game is CPU bound. Most games are. In fact, I’m not sure I’ve ever seen a modern Nvidia card get GPU bound"

This proves that the visual quality of XO games will have a big jump.

lifeisgamesok4135d ago (Edited 4135d ago )

"By the time games come out that use this?"

Games that use Directx 12 will be out this holiday season and that's coming straight from Microsoft

And Directx 12 has some stuff that will be good for gaming on Xbox One

Multithreading, Tiled Resources, hardware accelerated encode and decode, the ability to better manage esram, and more

dcbronco4135d ago

Another thing stands out. The idea of using VMs. Xbox One was designed with the cloud and DX12 in mind. They knew what was happening with DX12 within the Xbox team because there is part of the OS team that focuses specifically on Xbox. But the design of the Xbox One OS is like a server and it uses a HyperV. It's made to run VMs. When you put together things from rumors and actual reports, it seems DX12 will make Xbox One games look more realistic since lighting plays a major role in how we see the models. And just as the PS4 has it's GPU hardware advantages, the design advantages of the Ones APU should show once DX12 drops.

There has been so much talk from Microsoft and others about reading and writing on the same bandwidth simultaneously and from multiple sources with little bandwidth hit. And these are out of order chips that read and write to the same memory. I'm not a computer engineer, but I've gained somewhat of an understanding over the years of how this stuff works and I think the Xbox One is going to really show some things starting this year.

It's a good time to be a gamer.

Volkama4134d ago

HyperV + Direct12 = Better lighting?

Please show your workings out.

dcbronco4134d ago

I have no workings out, it's theory based on what I've read about Xbox One and technology in general. As I mentioned before I'm not a programmer or engineer. But it would seem based on what the article said and other things I've read that the design of One lends itself to having multiple VMs running different things. If DX12 allows you to go from on CPU core to using all core to send info to the GPU and that GPU can do VMs you shouldn't have the previous problems with having only one light source and no shadows. I've read that you can run a thousand VMs on one machine. It also seems that you should be able to use the cloud as your main light source on a map whether that source is a light bulb or the sun itself since that is a constant and doesn't need frame by frame updates.

I've read the OS only uses one VM for gaming now, but if DX12 is designed to allow all cores to communicate with the GPU and that communication is read write to the same memory space simultaneously for the CPUs and GPU then the natural evolution is toward fully utilizing those communication pipelines to run more VMs to allow developers to create more things. If one and a third cores currently run 3 VMs, the move to DX12 should allow eight cores to run a lot more. And that should lead to specialized VMs for lighting, physics and other things.

If you know better could you explain it more. I'm personally fascinated with the seeming possibilities of the design of the console. Or Frogboy if you are reading the comments.

KontryBoy7064135d ago (Edited 4135d ago )

I hope games get better performance because right now they run terrible to be "next gen"

ziggurcat4134d ago (Edited 4134d ago )

"This proves that the visual quality of XO games will have a big jump."

not according to phil spencer:

"On the DX12 question, I was asked early on by people if DX12 is gonna dramatically change the graphics capabilities of Xbox One and I said it wouldn’t. I’m not trying to rain on anybody’s parade, but the CPU, GPU and memory that are on Xbox One don’t change when you go to DX12. DX12 makes it easier to do some of the things that Xbox One’s good at, which will be nice and you’ll see improvement in games that use DX12, but people ask me if it’s gonna be dramatic and I think I answered no at the time and I’ll say the same thing."

http://wccftech.com/phil-sp...

and not even according to the article (edit - which you've misquoted to fit your deluded misterx agenda):

"It’s not magic

DirectX 12 won’t make your PC or XBox One magically faster.

First off, the developer has to write their game so that they’re interacting with the GPU through multiple cores simultaneously. Most games, even today, are still written so that only 1 core is dedicated to interacting with the GPU.

DevilOgreFish4135d ago

It isn't making the hardware faster why people are looking to dx12. it's about making use of the hardware, especially for PC gamers. The system requirements are too bloated for some games, barely utilizing one GPU let alone 2 or 3.

"Third, if you’re a XBox One fan, don’t assume this will give the XBO superiority. By the time games come out that use this, you can be assured that Sony will have an answer."

??

Don't quite follow, but anyways it's possible that any game with great optimization and treatment can either compete or tip the scales in some way. Who does not remember RE4's impact back in the day. Eitherway what's good for the game is great for the gamers.

Rimeskeem4135d ago

This is what the article said, not me,

DragonbornZ4135d ago

I find it funny that that is the one thing you felt you had to point out.

headblackman4135d ago

why are you even here? this is xbox news. not ps4 news. no one needs a fake developer in here trying to educate us on something that he has no clue one. another rambler is what you are. stop giving advice that no one needs or wants. go wait for greatness and let the real developers tell us what is and will be for these next gen consoles.

have a seat sir!

Andofaus4134d ago

Microsoft has been building direct X since the mid 90s and are the leaders the world over in software and middleware. On top of that Xbox One is custom designed for dx12 and other features such as tiled resources. Sony has a hell of allot of catching up to do so best of luck with that.

DougLord4135d ago

DX12 will only impact games if developers change the way they have been programming for 30 years. It won't be easy to program to keep 8 cores running at the same speed. On the PL you really don't see the benefit of more then 1 core until you start multitasking.

We have seen a similar move from AMD with Mantle. In instances where the GPU is considerably stronger then the CPU, you can get a 30% boost. But we need to realize that a 30% difference is barely noticeable. I have a gaming PC that was the nutz 4 years ago (dual 5870s). I wouldn't even consider upgrading until I can get 3x more Tflops. PS4 has 1.8 TFLOPs to Xone's 1.3. And you CANT TELL the difference. Add 30% and you close the gap a bit, but you aren't going to see much change.

1nsomniac4135d ago (Edited 4135d ago )

Have you watched or read any literature or the conferences about DX12?

That is exactly what it does, in a sense automatically arrange & spread the workload across every available core & within the API is simple developer access to manipulate this also so they can jumble the workload around themselves to make it even more optimised.

I'm not sure if you've made a typo (although you typed it 3 times) or you just don't understand but a real 30% boost is massive & very, very noticeable!

It won't make much difference to the XBone as the console API already works pretty similar to that anyway, as we've heard from Microsoft themselves but it will make a big difference to PC. As even in this day & age the majority of games still don't properly use multithreading or multiple cores.

DoubleM704134d ago

1nsomniac Yeah that's thing none of these Tech heads have not even looked at the conference. The power point presentation was all about the XBOX1 and Direct3D and how the XBox1 one benefits with it's 8 cores. It getting the same boost. Cutting the workload down on the CPU and making Huge Benefits.

Volkama4134d ago

DirectX 12 doesn't do all that for the developer automatically. It will take additional work from devs to utilise it properly. That is why Microsoft are also continuing to develop DirectX 11.3, so that some of the new features are made available with in the easier API.

Big name engines like Unreal 4 will probably handle a lot of that work 'automatically' though, so it's not like every little studio that wants to take advantage of the tech will need to learn how to micromanage threads and memory allocation.

Not looking good. Hopefully Asha Sharma is able to turn Phil’s disaster around.

dveio11d ago

To me it's still quite remarkable how they can cash-in 5.3bn in revenue in a single quarter, since their hardware is basically dead.

Jingsing11d ago

The stock mark is what makes Microsoft remarkable, They have convinced every institutional and retail investor to just keep piling money into them. Like many big tech giants they are just a big growing pyramid scheme. As long as people keep dropping money into ETF's that cover the market Microsoft will always be liquid. At the same time it is completely stifling innovation and competition. People need to start being more discreet in how they invest their money as it's killing the system.

Tanktopmaster9211d ago

Once they re-evaluate exclusive all will be fine….

S2Killinit11d ago

Riiiiight because people will just flock back to them for one or two games per year.

Jingsing11d ago

15+ years of bad performance is what they call irreparable in business. It is time for them to sell off the assets and get out of entertainment.

Tanktopmaster9211d ago

These declines are on the back of extra revenue received from releasing games like Forza horizon 5 on PlayStation. So I’m being sarcastic here when I said they should go back to exclusives. Killing off a revenue stream from Ps5 sales will only make things worse

Xbox boss: Memory crisis could impact next-gen hardware pricing

Xbox boss Asha Sharma has discussed how component shortages will impact the company's plans for Project Helix.

gamedeveloper.com
Eonjay13d ago

When does this end? Its killing everyone. Consoles and PC. And for what? AI? The benefits of AI are completely outweighed by the negatives. And the government should have never allowed one company to buy up all the RAM.

Lexreborn214d ago

This kind of proves this is an after thought product, most products like this are in r&d 5 years before they start mass producing. So they typically have the cost of components and things worked out long before assembly starts.

This is an assumption still, but I wouldn’t be surprised if project helix is similar to Scalebound,perfect dark and sod3. They had an idea but no actual execution other than concept stage. Being impacted by the ram shortage likely would also put this device 3-4 years out.

I’m not even sure MS has that endurance with Xbox yet

Fishy Fingers14d ago (Edited 14d ago )

I mean.... what?

We're at a point that Samsung wont even provide their own phone department ram because they can sell it at higher prices to 3rd parties (AI). Its more profitable to sell the ram than make their own devices with it.

You think because R&D starts 5 years ago the 3rd party component manufacturers will honour that price? They'll sell it to whomever is paying the most today, not some gentlemens agreement they made years ago. AI farms will buy more volume at higher prices than any console manufacturer will. It'll be the same for Playstation.

Lexreborn213d ago

Contractual agreements are not the same as “gentlemen” agreements. If you think that they work with their distributors a month before production then their entire business model is trash. They work with companies like nvidia constantly for building the graphics cards they need. They work with companies that build motherboards years in advance. This is what proper business planning does.

They are not buying components on a whim like a consumer. So again, considering the ram isn’t a singular module and is integrated into the motherboard I highly doubt they wouldn’t have a final schematic that they are supposed to be building around.

If they are delaying production another 3 years then it’s obvious again this is an after though project and is just trying to be responsive to their bad execution they had the last 14 years.

It also isn’t far fetched to use their failure to produce first party titles the last 7 years including the highly anticipated games I mentioned all being cancelled. That they would continue to you know… lie

Sitdown14d ago

You don't really know how this works huh?

Profchaos14d ago (Edited 14d ago )

Helix is going to be stupidly expensive

Instead of leaning into smarter upscaling techniques they're brute forcing hardware that will cost them dearly and it remains to be seen if it's genuinely going to provide a meaningful differential

I know in the oc.doace people like to brag about not using frame gen or dlss to get to high on a game but for the majority of players they happily use those technologies without a second thought

That's going to be ps6 vs Helix

Eonjay13d ago

Yeah with FSR 5 they should be able to offer a much cheaper version of Helix.

Eonjay13d ago

While this does seem to be the case, I am encouraged by the statement from Microsoft about wanting to provide affordable options. If this means a Series S style Helix, at least there will be something affordable being offered.

XBManiac13d ago

Series S is what has killed Xbox Series so... Will they dare?

blacktiger14d ago

It's called systematic inflationary. Yes we get it Microsoft, keep raising in the name ofall kinds of stuffs

pwnmaster300014d ago

Honestly if there was thing I learned from this generation is that new consoles arnt day one anymore.
I can wait 1-3 years.

DarXyde14d ago

Another important lesson from this generation: while Nintendo showed us that prices don't necessarily need to ever drop, we've now learned that waiting 1-3 years does carry some risk that prices increase. This generation is just bizarre in all the wrong ways.

LucasRuinedChildhood14d ago (Edited 14d ago )

The factors are largely external. Covid and Russia-Ukraine war causing inflation led to the first price increase in 2022.

Then we get Trump's tariffs increasing hardware prices, AI boom causing a RAM crisis, war on Iran causing a worldwide fuel crisis which impacts the cost of everything.

Gaming doesn't exist in a vacuum. The last few years have been a shitshow and lot of it was definitely avoidable.

DarXyde13d ago

LucasRuinedChildhood,

For sure. No disagreement on the external factors doing a lot of this. Where I have to gently push back however is on two fronts:

1. The pandemic definitely caused some issues: asynchronous development was a big issue and really complicated timelines and affected game quality. At the same time, when it comes to price hikes, it's really difficult to know what was genuine necessity and what was taking consumers for a ride. The pandemic brought about "stag-flation" which was increasing prices and stagnant wages, which was a problem caused by supply chain constraints. There was also "Greed-flation", where companies that were slightly affected or had no issues took advantage of the situation and squeezed everyone citing supply chain issues when there were none.

2. It's definitely true that the tariffs, AI boom, and RAM crisis were all things enabled by tech broligarchs throwing money at this caricature of a world leader, one of them being Satya Nadella. I don't think Sony and Nintendo have contributed much to this problem if at all, but Microsoft's Nadella I feel was instrumental in causing every one of those issues. Microsoft as a company contributed to both candidates (though they gave Harris 4x as much if I recall), but Nadella was all in on letting AI run wild. He paid for unregulated AI, and got a war that's not a war (even though Trump called it that at least five times on television) that screwed up helium access. So for me, I feel that one of the players in the gaming industry is a key architect of these issues, and for that reason I struggle a bit to think of it as "external".

A good start would be to release games to go with the console. My Xbox Series X has gathered dust virtually from launch. My advice would be to ditch a next console and release games on PC, PlayStation and Switch. Another idea would be a hybrid console based on Xbox Series X tech and go the same route as Nintendo. Another idea would be to pull out of gaming altogether. Plenty of options there.

Reaper22_12d ago

Why would they pull out? They have the momentum. Sony has been getting nothing but bad news lately.
