I'm gonna buy it regardless on PC just to play around with it. Looks like it will be good fun to play for like 20-30 minute spurts when I'm not playing WoW or LoL

Looks great hope I get into the beta :)

XO looks to have a hUMA like system for shared memory space by GPU/CPU


More HotChips info (from NEOGaf):

XBox One SOC has a CPU, GPU, and 15 special-purpose processors. Total of 47MB of storage on-chip.

Audio offload processor in XBox One SoC are "completely designed by Microsoft" and have "more than a CPU core worth of processing"

https://twitter.com/Daniel_Bowers/st...41578639929...

XBox One CPU has eight "modified" AMD Jaguar x86-64 cores, in two clusters of four cores. Modifiations to memory sharing & bandwidth.

@docLEX

It's customized to be sure, and it is an impressive feat of engineering to slap that much on a die and keep it at/under 100watts.

Has it's own unified/shared memory solution, customized enough where under the same conditions it might perform better than AMD's hUMA.
204 GB/s peak bandwidth with data highways that can transfer bits at a rate of 200GB/s or more across different parts of the SoC
8GBs Flash Memory (probably hybrid HDD function)
47MB of on-die storage (cache)
SHAPE -relates to audio (offloads to one on the CPU cores) I was skeptical about how this would function on the X1


There's still some things that need detailing but ultimately this is shaping up to be a much more thoughtful design than I had initially thought. It does appear that the X1 has what it needs to compete very effectively this generation. The best games for this platform will obviously be 1st party titles, only they will probably utilize all of the features and functions of the One. And there is ALOT for these developers to go through, this is a very heavily customized and very busy SoC doc.

But what really is interesting is that the complexity of the system off-sets the supposed lower profile that so many articles have been claiming for these many months. MS didn't lie, they really did touch every single piece of silicon on this system. No standard off-the-shelf fair. The CPU is completely customized, and MS has thrown in enough hardware optimizations for the GPU to keep devs interested or mystified.........depending on how you look at it. It's pretty difficult to draw comparisons at this point. The PS4 powers it's way through most of it's functions very handily, but the X1 will finesse it's way to similar performance. Even doing some things better than the shader muscled PS4.

However, it's not all sunshine and bunnies. Unlike the 360, some of the X1's best customizations are not used as vehicles for innovation. Some are employed as tools to pick up performance efficiency where it was needed. This is where it gets a little odd for me, because design choices MS made to keep the system low cost and low on power forced them to come up with both creative and highly complicated solutions that in the end produced possibly the LARGEST CHIP ever manufactured. Because the chip is so large, alot can go wrong during fabrication. So MS has tapped out redundancy to ensure that if one part of the fab fails, the entire chip won't be lost. Seriously, where was that SoC team to tell them that if you cut a design corner here, you'll have to build a whole room to make up for that corner later? It's interesting how MS went from early multiple APU designs to one massive SoC that is bound to produce supply problems for them in the early goings. If they can get past this with acceptable supply issues, then get to 22nm as quickly as possible, they'll have a real winner on their hands it terms of cost effect manufacturing.

Don't get me wrong doc, we're going to have fun this generation. Well maybe I shouldn't speak for others, so I AT LEAST intend to have fun. Others may carry their grudges for awhile longer but I imagine they'll get around to gaming at some point. But this isn't likely to be a long lasting generation. I give Sony and Microsoft till 2016 before they start realizing that they didn't do enough. Looking at mobile technology coming in the near future, you have to understand that there will be tablets more powerful than these consoles in 2016-17. MS and Sony won't have a choice but to start thinking about 2018 machines or risk losing marketshare to mobile platforms that cost fractions of what it takes to launch dedicated gaming hardware. Unless it's MS' plan to take this SoC mobile by then. It would certainly explain why they jammed everything on this die.

Still there is ALOT that we don't know about this SoC, MS did not go into details about CPU or the GPU. And I'm talking about clock speeds and FLOPS, I'm talking about filling in the blanks on the GPU's CUs , their dual cache stages and the SIMDs.

This confirms that the hardware spec leaks were basically 100% accurate. The gap between ps4 and xb1 is basically as people had claimed.

Thats a big bandwidth jump (old68MB)109MBmin (old170MB)208MB Peak! and were did the 42MB cache come from? also 8GB of flash! guess thats for game pause/resume and the 30min video recording, game enhancments??

Yup, at least we can finally put that shit to rest.

Yeah still some stuff to clear up, but the dev's and games will all be talking soon.

http://www.youtube.com/watch?v=5hfYJsQAhl0

It same as before only 53mhz clock speed for gpu nothing else. They just had a tech guy with jargon's and all trying to tell others about bandwidth of XO can compete with gddr5 in games ?

100% accurate? Mmmmm.....no. I don't think so. There's a few things the leakers either got wrong or missed altogether completely. But that shouldn't really surprise anyone, claiming that kind of accuracy so many months from a platform's release is more than a little arrogant. Even for them.

For starters the eSRAM. The expositions of the leakers had one large single 1T or 6T = 1.5 Billion transistors component. Yesterday we found out that wasn't the case. As it turns out the eSRAM is a pool of 4 memory controllers that each do 8MB of data. This is also how Microsoft arrived to the 109GB/s, and it also appears that the 204GB/s is sustainable in real-time gaming circumstances. So real numbers, no creative math there.

The second is of course that the diagrams clearly show that the X1 supports HSA/hUMA as it is using synchronized page tables. No further elaboration is needed after that, the leakers (Extreme, DF) suggested that the X1 didn't have uniformed memory access and they were WRONG. And not only is this issue DONE, it looks like the X1's uniformed path is a great deal more efficient than AMD's hUMA under the same conditions. The question of course arises, if they didn't know that the X1 supported HSA/huma, then why would they naturally assume that it wouldn't? WTF?

Then there are the other things they could never account for because their information was either out of date or poorly extrapolated. But again how could they possibly know about the 8GBs of Flash, the 15 special-purpose processors with their own chip sets, the modified Jaguar cores, or that the esram is 4x256bit not just 256bit etc etc. There's ALOT of things going on in those diagrams that VGleaks and Co didn't have a single solitary clue about and went completely UNREPRESENTED in their leaked specs. In fact those diagrams DON'T LOOK ANYTHING LIKE the VGleaks specs. So what are they going to do now, pretend that they knew about all of that stuff but they chose not to reveal it?





And it's STILL not done, as we're still waiting for the CPU and GPU diagrams which were conveniently left out by Sell and O'Conner yesterday at Hot Chips. And I'm almost certain there will be some more "we didn't see that" moments for those specs as well. But while we're still on these diagrams, a few things stood out for me-

-Host GPU MMU, where everything is both connected and flows through this yet undefined area of the Graphics Core
-Dx11.1+ graphics core with "custom graphics" and compute command processors (a total of 4 to be precise)

Then you add this dude's Linked resume to itNope I'm not claiming a discrete GPU, I wouldn't dare go that far. I'm simply pointing out that an AMD employee who was on the Xbox One project is claiming that he did graphic core design verification on an APU/DGPU. Any further speculation is optional and requires salt. lol! Some folks are making a big deal about the first diagram that has "Main SoC" listed, but that could just mean that the other SoC is located within the Kinect sensor so people definitely need to calm down about that.

I also realize that I spoke too early about this. Microsoft has thrown so much optimization and customization at this SoC that it could take years before developers get around to all of it.

This is just in. According to the latest rumor XO latest hardware details, including gpu will be revealed sometime later before the release .

On the more serious note. It will be interesting to see if esram + ddr3 turns out be good enough than most people think.

Here is a nice tech breakdow.

Please stop posting positive stuph or else we might read trolling comments like "Yup, at least we can finally put that shit to rest" again :D [irony off]

There's so much going on, it'll be fun to see whether it's paranoia, naive thinking or fact - Sept. 29 will reveal everything we don't know yet

Clearly i was wrong. *sigh*

I'm sure after sept 29th we'll still be hearing about speculation and secret sauce *shrugs*

lol

So what's happening on Sept 29th?Agree.

"Insider" again:

Sony has a contract in place with AMD that specified that they would have total control over the hardware public relations aspect. Which runs out on 29 September 2013.. up intill this date Microsoft is not allowed to go public. It is in the license agreement with Intel as well. Sony had a 6 month exclusive hardware agreement basically. First in best served. This has not effected nintendo as they using different cpus.. And this sort of thing happens all the time in the pc cpu and gpu markets.. .. sad but true. :)

Lol this. It is like in order to get some attention you have to make a retard post, a cynical post, or a trolling post. Some one bring some sense to the situation and is mostly ignore :P

I had heard about certain aspects of the NDA lifting later on this year but I didn't know it was anything as strict as this.

Nice :)
