AMD: PlayStation 4 supports hUMA, Xbox One does not

You are kidding yourself if you think plenty of PS4 and XB1 games won't take advantage of prebaked lighting this gen. Just because you have more power this time around doesn't mean that there is no longer a need or a desire to fake certain things. If it makes the game look better devs will fake things where necessary.

Panties in a bunch much? You sound like you speak for MSFT.

This is huge, game changing huge. I'm going to assume MS had to take this feature out to make room for the eSRAM on the die. Meanwhile, Sony took the higher latency hit of the of using GDDR5 but are making it up via tools such as this. A great article on how Sony overcame bottlenecks on the PS4 can be found here;

It's been proven hundreds of times that GDDR5 latency is not higher.
 
It's pretty early days yet, but looking at the XB1 games so far I think the console will be fine.

You're kidding me, right? I'm referring to both consoles. Just because you have more power this time around in both consoles doesn't mean that any and all technical challenges that might ever arise are instantly solved by that extra power. There will still be plenty of situations this generation where developers will find it more effective to fake something rather than do it for real, and this will be true on both the PS4 and XB1.

AMD states that PS4 doesn't even support hUMA. So what the hell is this thread all about.

I literally LoL'd at this comment...

You've just gone off on a tirade about someone attributing something to an AMD employee that wasn't actually said...

And then you turn around and COMEPLETELY misquote the AMD email and say that the email says the PS4 doesn't have hUMA...oh man...

Didn't they said this before the X1 was revealed? So - of course the PS4 would be the most powerful console at that time because the X1 wasn't announced.

Both APU's would have LONG been designed and delivered at that point...and I thought the article was written today which stated that?
 
I'm pretty sure AMD knows what they are talking about. However, it will probably take a little while before devs are going to make good use of it. Similar to GPGPU like Cerny already explained. Over time the gap should get wider, but you won't see it that much in launch titles.

That being said, there is probably some truth to the rumour that multiplats run better on PS4. It's popping up way too much recently to just be all bullshit.

Everyone should pick their console based on games and features and not worry about these little differences in graphics.

So now Level 1 AMD support guys have access to heavily NDA protected documents about PS4 tech ... it makes sense to me ... and of course they can answer any question about that tech

Interesting, considering Forza 5 and Ryse look better graphically than any PS4 game.

Except they don't. Ryse has pretty bad texturing and detail compared to Killzone Shadowfall and Forza, do you really think it looks better than DriveClub?
http://ca.ign.com/videos/2013/08/20/forza-gameplay-cruising-in-a-ferrari-gamescom-2013

One is less detail at 60fps and the other is more detail (much larger 3D environments) at 30, hard to judge. Not too mention that Forza 5 prebakes it's lighting while Driveclube does not and uses accurate reflections.

Wait, Forza 5 has prebaked lighting? Really? Why are we even talk about it then? It's clearly up-resed last gen tech used there. Not worth the discussion. Let's see what they can do in Forza 6.
 
Even more excited than I was yesterday.

Thank you, Based Cerny.

According to the OP, AMD (the people making the GPU for both consoles) says this isn't a "little difference."

I actually fail to see why Xbox One doesn't support what AMD's calling hUMA too. hUMA is just UMA with cache coherency meaning that all the devices go to the RAM pool via the same cache buffer. May it be that the move engines bypass APU's cache in some way?
Also I don't think that this will give PS4 as much an advantage as AMD's trying to make it sound. They're using this case to market their APUs but the truth is that even NUMA PCs aren't that behind UMA consoles in practice. Difference between UMA and hUMA will be even less noticeable.

Ahhh hahaha.

Anyway, I'm really trying to keep the hype down. The graphical gap between the PS4 and X1 on paper is looking tremendous. Everyone knows that Sony will excel in hardware far above the software-focused Microsoft, but did Sony really go THIS balls-to-the-wall this gen? I felt Sony had to be come out with all guns ablazin' this time around, but...really this much?

I'm just having a hard time seeing how Microsoft could let this happen. In this world of leaks and such, how can they undershoot Sony so badly? I just don't get it.

I don't think anything looks as good as Second Son right now, but still...should I allow myself to give into this hype?

...nah, I'm going to just wait and see and let myself be impressed. And hope.

You could pin it down to MS focus on creating a media box.

it's a snowball effect of > huge memory footprint to accommodate several operating systems> 8gb ddr3 solution> Esram to compensate for the low bandwidth of ddr3> little space on the die to accommodate a beefier GPU

on the other hand, Sony focus on creating a gaming machine first and foremost paid dividends.

I think it's because the CPU has no access to ESRAM so it's not really unified.

In 15 minutes no less, if I'm reading the thread right?

Hey XBox support was on the ball on Minecraft exclusivity so I'm sure AMD support is on the ball here.

Posters early in the thread: When AMD says things you listen
Posters now: That response doesn't mean anything!

Why are so many people trying to swim upstream on this?

Some of the posters in here could get a morning show on FOX news with the amount of 'questioning' and spinning they are doing in this thread.

Don't mind them. They're just in denial & can't handle the truth. It's hilarious, though.

Better? No. As good as? Yes

So far, I don't think there is any stand out launch title nor is there any game which clearly looks better than the rest; although KZSF has impressed me the most so far. Ryse is up there though.
 
Can someone please tell me why everyone is saying third party titles will be equal?

The belief that if you wish hard enough, you can make anything come true.

It's the same thing driving people to say that AMD, the people who designed these damn chips, doesn't know what they're talking about.

I think driving games should be banned from screenshot comparisons because there is never any actual gameplay. It's just supersampled photomode which looks nothing like the game.

Second son is top teir for me. It looks smooth as fuck with great visuals. And that is coming from sucker punch a dev that are not really tech gods.

There is a post in this thread that Microsoft should somehow punish AMD for saying this. How are they going to do that? Not give them a cut of that Surface action?
 
Just out of interest, what do you feel are the best looking launch titles?

Killzone SF is one of them, obviously, but there are games that I find more visually appealing. Maybe it's cause I have more interest in the other games, and that's biasing my opinion, but that's how I see it.

Ryse looks unbelievable based on the SP footage I've seen. I think Ryse's SP is the most next gen looking thing I've seen from a pure graphical standpoint.

Forza 5 looks pretty damn amazing on top of the fact it's running at a native 1080p at 60fps.

Killer Instinct is yet another that looks incredible. I love the game's look, especially a big fan of all those particle effects. I've seen people say "Oh, it's just a fighter, it should look amazing," but I remember seeing a straight up 1080p gameplay video on youtube, and was blown away by how incredible the game looks. It really is a looker. It doesn't matter if it's a fighter, it still looks insane.

And this one only occurred to me yesterday, but the waverace section in Kinect Sports Rivals looks pretty damn unbelievable. I'm not exactly putting it above Killzone and all the rest, though. I just thought it deserved mention as legitimately one of the better looking graphical showcases on the two consoles at launch.

Dead Rising 3 is another game I think looks pretty damn awesome, too. It's only issue is the framerate, but it's got a lot going on I think it's a very good looking game. Great lighting, solid textures, very packed and busy environments, lots of zombies on screen, open world, no loading times etc. But of course all of this becomes far less impressive if they can't fix the framerate.

And although I may not buy it, I gotta give a nod to NFS. That game looks pretty damn amazing for a launch game.
 
Did you watch the MP trailer? It looks a lot better than the E3 footage. I think it's easily the best looking launch game now with Forza right behind it.

I actually haven't. I'll check it out right now and tell you what I think. Btw, if you happen to have a good link for it, let me get that, because sometimes these videos get posted in so many other places, and the quality is just bizarre compared to what it really looks like.

Okay, just watched it on the official playstation youtube page, and I gotta say, definitely one of the better looking launch games. I was a bit surprised (more than a bit actually) at how good it looked in MP. It looks really damn good. That said, I don't know if its my lack of interest in the game, but I'm not all that excited by what I see, but I can at least look at it and acknowledge that it's undoubtedly a very strong visual presentation that the game has going on, one of the strongest on display of any next gen game so far. I'm not too big a fan of Killzone's visual style, though, but it does look amazing.

Thats what I'm saying. All these indie games do nothing for me while XB1 has AAA titles across the board. This isn't the psone days when it could only push 150k polygons compared to N64 300K with texture shading and anti-aliasing. The visual difference in Real Games is going to be small.

Have you seen Kilzone Shadow Fall...? ; )

I disagree strongly with this one. DR3 looks like a last gen game AND has FPS issues

Based on some bad screenshots it does, but if you really watch this game in action without a crappy video feed, it seriously does look incredible. It only enhances my impression of it when you see all that the game has going on. If the framerate is fixed without serious compromises to the visuals of the game, I think it's a very impressive achievement. I'm not seeing a last gen game at all.

It's doing way too much for that classification.

Can GAF make it a policy not to be able to do graphics comparisons with obvious bull shots? Or can we just call for a ban to bull shots entirely please?

Edit: and looking at the recent postings, I certainly wish devs were more forthcoming of what they're demoing on high end pcs rather than real hardware.
