Textures are just arrays of data. GPGPU is used to update arrays of data on the GPU. You'd swizzle them for optimal cache coherency for the access pattern you'd use on each processor.

I'm sorry, I didn't know you're being forced to see this thread.
Every GPU mem controller I'm the past 10 or so years will do texture swizzling for free the glorified DMA units Microsoft renamed dont do anything special really.
Also what does swizzling have to do with cache coherency I could see it having to do with better cache hit rate based off pretty much transposing the texture, but I fail to see the relevancy to cache coherency.

Bringing up the fact that an author made a similar article with anonymous sources that was FUD isn't Ad Hominem. It's questioning his credibility which is right to do. Ignoring that he made FUD articles in the past is being ignorant. I know the XBone is weaker, but when there are much different words from different developers and most of it is coming from "My friend said". I'm finding it hard to believe if we're playing telephone constantly and this article is starting to re-enforce that were just playing one long game of telephone and the final answer of the power difference will be "Purple Monkey Dishwasher".
Swizzling the textures into tiles brings the rows above and below into spacial coherency. Having the rows in cache lines means you get cache coherency. It's a different type of coherency to the type hUMA provides. Another overloaded term.
You can also have temporal cache coherency.
Are you talking about vector element swizzling? That's a different type of swizzling.

But that coherency isnt a problem for the GPU as its backed by a shared l2 cache so everything is coherent in l2 regardless of orientation.
They will swizzle a whole bunch of things including textures, here's a hint, GCN cards usually have 2 DMA controllers the XBONE has how many DME's that can swizzle ? It should tell you what they are.
This is going to keep going.
I expect Microsoft to start resorting to direct parody ads like what they are doing with Windows Mobile - http://www.youtube.com/watch?v=20LgureMuWo
It's their style.

Pretty sure all of this is gonna be irrelevant later on in the console cycle... none of this sound any different from the heat sony faced when the PS3 was being launched. Anyways, i dont mind paying the $100 extra for it. Its more my speed.
Those same devs also said the upclocking in the Xbone CPU "is not significant" and "does not change things that much."
And we don't know about the PS4's audio chip, so it's literally impossible to say that the Xbone's is better. It may be, but we don't know. And even if it were, big deal. It's an audio chip. Not exactly big bragging rights.
I'm not talking about hUMA style coherence. I'm talking about spatial coherence.

I'm also not talking about swizzle operators, I'm talking about tiling.

They all do tiling too. It's nothing new nor special.
The fact is that MS is trying to flog something for £430 that isn't worth £430. Maybe if it were 50% faster than PS4 that would be a more sensible price.
I can't speak for Kojima, but Carmack has also flat out admitted he hasn't had his hands on the hardware or done any kind of testing on them. So his opinion on this is meaningless. .
This is going to keep going.

If it becomes common practice for PS4 games to be held back graphically just because of the Xbone, I'm going to be pissed. The implication that devs/pubs might do it just to keep MS happy is really disturbing.
Hang on what was that bad taste thing? You're not telling me that's an official MS ad are you?
@crecenteb: The iPhone parody commercial that Microsoft made and then pulled. http://www.youtube.com/watch?v=20LgureMuWo
Terrible, awful advertisement. It wasn't even remotely funny.How fucking disgusting. Even if you hate Apple, it's sick to use a stand-in for their dead founder in a shitty parody.
Yep it is. Official video got pulled after hours of negative feedback.Hang on what was that bad taste thing? You're not telling me that's an official MS ad are you?

Ad Hominem is attacking the person rather than the point he made. Even if every other word a person has ever spoken in the past has been a complete lie, it doesn't mean the next thing out of his mouth will be a lie. Attack his points, not him. Prove him wrong. Show me devs who have actually worked on the two consoles who refute what the devs he quotes have said. Otherwise, it's grasping at straws.

So a GPU on the market at the moment can memcpy between two locations and tile the output?
Why would yo want to tile the output?
If people are that bothered that the console they are buying is less powerful then an another why not buy the other one instead? Problem solved, no?
Dude, the numbers are right there in front of you. I don't know what's so hard to believe. Of course Kojima isn't going to say there's a big difference when he just had MGSV at the Microsoft conference.
The numbers. Look into them. They represent a 40% to 50% advantage in GPU power for the PS4 so it really isn't surprising when anonymous devs confirm that. And that doesn't even account for the customizations Sony made to give it an even further advantage. We know the details of each system. There is no secret sauce/wizard jizz in the Xbox One design that closes the gap in any meaningful way. But by all means feel free to prove us wrong if you know something. I can assure you that if the performance gap were false, MS would tell us why in detail. But nope, lol we made directx.
IMHO if you are buying a console solely based on power your reasoning is very flawed.
Well it's a good the PS4 is the most powerful console and the cheapest

Why is everyone forgetting the cloud when comparing the consoles? MS doesn't have 300.000 servers for nothing.
Who cares about the price? If you must have only ONE console, if you are not choosing because of the game line up then your priorities are off. IMO of course.
The only reason I am getting both consoles is because they both have game series that I like that I can not get on pc.
How fucking disgusting. Even if you hate Apple, it's sick to use a stand-in for their dead founder in a shitty parody.
All MS servers are first and foremost there to service their enterpise users. Xbox division [when is not loosing money] is earning ~2% of total profits for MS. They are insignificant, and if Xbox division ever threatened Windows, Office or Enterprise business, MS would destroy it [or sell it] in a instance.
And off course, cloud cannot help rendering in the games. It can run secondary apps that can manage MP servers, leaderboards, stats, and some secondary AI states. Nothing on your screen will look "better" because of the cloud.
Oh, wow. Microsoft's PR really is the worst, isn't it?
Keep spreading the FUD and try reading the article again. He said he hadn't done benchmarking on them.
He clearly has got both dev kits and said he can't go into specifics due to NDA
To dismiss his opinion is idiotic.
To be fair to them, it's supposed to be Tim Cook and Jony Ive.
It's just lame.
This is going to keep going.

The magic word "IMO". Thank God there are other opinions which are not yours.
