"the console reserves up to 3.5GBs (of its 8GBs) of RAM for the operating system, leaving developers 4.5GBs to play with." Though the "benchmark can be "flexible" by up to 1GB, meaning developers can request access to a full 5.5GBs of RAM, but only if the PS4's operating system processes are streamlined enough to accommodate the drop in its allocation."

[QUOTE="CanYouDiglt"]While I am in no way excusing MS for this but you do know many companies are involved with NSA Prism data gathering. One example is facebook was one of the companies and look how much Facebook is intergarated into PS3. There is also companies like Google and Verizon which you probably access.

You Microsoft apologists are insane I dont care about facebook or about any other company who has signed We are talking about Microsoft. What others have done doesnt excuse Microsoft from what Microsoft has been doing and is still doing. That is a fallacy Thats like saying, "who cares if that guy murdered your brother, you see that other guy over there, he is a murderer too so we should let your brothers murderer off the hook etc" NO we arent going to let Microsoft off the hook.... And the fact is Microsoft WAS one of the first to sign up for PRISM. Microsoft IS THE BIGGEST supporter of spying on you. Microsoft is the BIGGEST signee of PRISM F@ck Microsoft.

The PS4 is more powerful, playstation exclusives have always dominated and will continue to... It doesnt even stop there...... The PS4 will have the same entertainmemt features the xbone has except unlike Microsoft, Sony will still KEEP the MAIN focus of the PS4 on GAMES and on gamers (like Sony always has) And all of that with the PS4 will cost you 100$ less Forget the xbone.... Im not going to put up with Microsoft's b.s WHEN there is a better in every way yet cheaper alternative in the PS4 Blog it. Also, at least Microsoft still supports their console unlike Nintendo who abandoned the Wii 2 years before Wii-U. Those lackluster exclusives don't count.

Thank god we can finally put this b.s rumor to rest Sony responded. Digital Foundry was proven WRONG about the distinction between flexible memory. Sony basically destroyed what little credibility Digital Foundry had left. Also, the over all numbers Digital Foundry came out with were also proven wrong as many insiders and PS4 developers have confirmed Digital Foundry was full of it Digital Foundry really does look like a bunch of Microsoft shilling a$$holes now Haha i love it This "ramgate" and the previous "7 second recording" lies have forever tainted Digital Foundry and exposed them for the Microsoft shills they are The ONLY way they could get back into gamers' good graces is if they made very positive PS4 threads every day, every hour, for weeks straight etc
I'm choosing the PS4 over the X1 simply because SCE's resume is far more impressive than Microsoft's in the gaming industry.

Much more impressive in fact Plus Sony has been with gamers from the start and HAS NEVER tried to pull half of the anti consumer policies Microsoft just tried to pull on us. Microsoft only stopped because they were losing pre order sales. People need to remember that. Microsoft flip flops because they chase money. Microsoft tries to extort as much profit as possible at any expense like the typical big shady American corp Microsoft is souless corporate scum... While you can sense Sony is passionate and genuine about games and gamers. Sony has never needed to flip flop because they have always been for the gamers, and because- Sony just wants to put out great products people will love that they(Sony and gamers) can be proud of etc When it comes to gaming, vaules, and buisness ethics etc Sony just destroys Microsoft, the playstation has always been better etc Sony are SAINTS compared to Microsoft. Reality shows that: - Sony has never tried to enforce anti consumer always online, and DRM Microsoft policies.. -Sony doesnt enforce an always on Kinect spy cam -Sony in conjuction with their stellar first parties continues to bring the gaming goods with variety of top notch playstation exclusive after exclusive. - Sony sells a 50% more powerful console for 100$ cheaper. -Sony doesnt put netflix behind a paywall like Microsoft is doing -Sony is close to their developers, and lets them make the great games they want to make etc -Sony not only allows creative freedom among their first parties, they encourage out side the box thinking. Mean while Bungie had to buy themselfes out from Microsoft because Microsoft was FORCING them to only do Halo.Microsoft also KILLED Rare. -Sony actually innovates WITH GAMING specific features - PS4 share features etc. Microsoft's idea of innovation is kinect and pizza hut achievements lol. Basically, ^^^Sony does all THE OPPOSITE of everything Microsoft does and Sony stands for every thing pro gaming and pro consumer that Microsoft is against. Microsoft is always content to do the bare mininum in all regards with cookie cutter games(Gears/Halo) and basic cookie cutter features(party chat being the biggest feature on xbox live LMAO) And i can keep going on and on with MORE examples etc Sony/playstation>>>>>>>>>>>>>>>>>>>>>>>>>Microsoft/xbox F@ck Microsoft for life.

to TC, the audio processors are both very interesting on the PS4 and the XBO. Both are good, but it looks like the XBONE has a significant advantage with the SHAPE audio block.

So does the PS4 have support for some type of heterogeneous unified memory? Maybe. And the Xbox One? Maybe.

[QUOTE="super600"][QUOTE="voicereason"] Yeah, just beacuse i dont worship all things Microsoft the way you do lol I like you but i would bet anything that im more of a real gamer then you will ever be and I always speak the truth. The playsation is better, thats why i prefer it. Sony has BEEN supporting gamers and HAS NEVER flip flopped like Microsoft Thats why i will always support Sony over Microsoft etc The fact is the xbone is a joke in ever single way in comparison to the PS4. If you are a REAL gamer why wouuld you NOT care about all of the vast advanatges the PS4 has over the xbone Yeah, Microsoft has shills on forums trying to downplay all of those advantages or trying to tell you to ignore them. That WILL NEVER work. This isnt the 1950's. We can easily look up the info. We can spot Microsoft b.s PR talk better then ever now too. Its because we are gamers that we must STAND UP for gaming and support Sony who is the only one FOR GAMING, while we must fight Microsoft off etcvoicereason
Sony cares little about you. If they cared about you they would not force you to pay to play games online. Sony only cares about getting your money like 99% of corporations.
So tired of this ridiculous nonsensical deflection type "argument" from xbots Of course all companies care about profit... But there are some like Sony who you can still trust to be fair and put out great products that you want (50% more powerful 100$ cheaper PS4) While Microsoft wants to extort as much profit from consumers as much as humanly possible and at any expense As per the xbone being 50% weaker, 100$ more expensive, and coming with a mandatory spy cam IS unacceptable on all fronts. SNIP On GCN CU compute power, X1 has about 71 percent of PS4 or PS4 has about 40 percent additional CU power over X1. On triangle rate, PS4 has about 94 percent of X1 or X1 has about 6 percent additional tranagle rate over PS4..[QUOTE="R3FURBISHED"][QUOTE="BoxingandGaming"]OP you should add that the PS4 supports hUMA while the xbone does not, BoxingandGaming

You are so clueless. Of course AMD is going to try and deny it. Microsoft is a partner too. AMD gave your typical PR response so as not to upset any one etc Thats ALL that is. Read this: Article from Germany's biggest and very reputable IT news site, found by gaf member Junior WICKED: http://m.heise.de/newsticker/meldung/Gamescom-Playstation-4-bietet-Unified-Memory-Xbox-One-nicht-1939716.html?from-classic=1 Translation: [Quote=" "]Although both upcoming game consoles Xbox One and PlayStation 4 are based on AMD hardware, only PlayStation 4 incorporates hUMA [Heterogeneous Uniform Memory Access] for supporting a shared memory space.This was explained by AMD's Senior Product Marketing Manager Marc Diana to c't [big German IT magazine] at gamescom.This should put the 3D-performance of PlayStation 4 much farther ahead of Xbox One than many have expected so far. AMD sees hUMA as a key element for drastic performance improvements in combined processors. AMD's upcoming Kaveri desktop processors support hUMA as well.Behind the scenes, c't could hear from developers that the 3D-performance of PlayStation 4 is very far ahead of Xbox One. Back in April, AMD manager Phil Rogers explained to c't that hUMA improves 3D-performance in particular. "Game developers have been eager to use very large textures for years. Until now they had to resort to tricks in order to package parts of larger textures into smaller textures. That is because today a texture has to be located in a special place of physical memory before the GPU can process it. With hUMA, applications can work with textures much more efficiently". AMD will give more details on hUMA at its upcoming developer conference in November.
In quick summation: http://m.neogaf.com/showpost.php?p=77491025&postcount=84 Update 1: hUMA: Heterogeneous Uniform Memory Access (Yes, people already made tons of "sense of hUMA" jokes)http://arstechnica.com/information-technology/2013/04/amds-heterogeneous-uniform-memory-access-coming-this-year-in-kaveri/ [Quote=" "]Even with the integration of GPUs and CPUs into the same chip, GPGPU is quite awkward for software developers. The CPU and GPU have their own pools of memory. Physically, these might use the same chips on the motherboard (as most integrated GPUs carve off a portion of system memory for their own purposes). From a software perspective, however, these are completely separate. This means that whenever a CPU program wants to do some computation on the GPU, it has to copy all the data from the CPU's memory into the GPU's memory. When the GPU computation is finished, all the data has to be copied back. This need to copy back and forth wastes time and makes it difficult to mix and match code that runs on the CPU and code that runs on the GPU. The need to copy data also means that the GPU can't use the same data structures that the CPU is using. While the exact terminology varies from programming language to programming language, CPU data structures make extensive use of pointers: essentially, memory addresses that refer (or, indeed, point) to other pieces of data. These structures can't simply be copied into GPU memory, because CPU pointers refer to locations in CPU memory. Since GPU memory is separate, these locations would be all wrong when copied. hUMA is the way AMD proposes to solve this problem. With hUMA, the CPU and GPU share a single memory space. The GPU can directly access CPU memory addresses, allowing it to both read and write data that the CPU is also reading and writing. hUMA is a cache coherent system, meaning that the CPU and GPU will always see a consistent view of data in memory. If one processor makes a change then the other processor will see that changed data, even if the old value was being cached.As well as being useful for GPGPU programming, this may also find use in the GPU's traditional domain:graphics. Normally, 3D programs have to use lots of relatively small textures to apply textures to their 3D models. When the GPU has access to demand paging, it becomes practical to use single large textureslarger than will even fit into the GPU's memoryloading the portions of the texture on an as-needed basis. id Software devised a similar technique using existing hardware for Enemy Territory: Quake Wars and called it MegaTexture. With hUMA, developers will get MegaTexture-like functionality built-in.Update 2: Well explained: [Quote="WICKED"]On a classical system you have a RAM pool and a VRAM pool that are physically speperated. Copying data from one pool to the other creates latency. The GPU is very good ad hiding latency. What it needs most is high bandwidth. The CPU on the other hand is extremely sensitive to latency. The CPU needs extremely low latency to work efficiently. Copying data from the RAM (CPU) to the VRAM (GPU) creates latency, but that's okay for the GPU. Copying data from RAM (CPU) to VRAM (GPU) and back to the RAM (CPU) creates even more latency. It's too much for the CPU. The copying alone takes longer than the computation wich makes this roundtrip highly ineffective. Xbox360 and older APUs have a unified RAM. This means that the RAM is no longer physically seperated, but even though it's the same RAM chips, the system still distincts between memory partition for the differenct processors. You still need to copy the data between CPU partition and GPU partition, but this will be much more efficient than copying it between physically seperated pools. But it's still too much latency for a CPU, GPU, CPU roundtrip. PS4 will have hUMA wich means that you no longer need a distinction between CPU partition and GPU partition. Both processors can use the same pieces of data at the same time. You don't need to copy stuff and this allows for completely new algorithms that utilize CPU and GPU at the same time. This is interesting since a GPU is very strong, but extremely dumb. A CPU is extremely smart, but very weak. Since you can utilize both processors at the same time for a single task you have a system that is extremely smart and extremely strong at the same time. It will allow for an extreme boost for many, many algorithms and parts of algorithms. On top of that it will allow for completely new classes of algorithms. This is a game changer.Update 3: Further evidence: Sony joined the HSA (Heterogeneous System Architecture) Foundation originally co-founded by AMD while Microsoft has not:http://hsafoundation.com/ Update 4: The main summary so far: [Quote="ElTorro"]To summarize the evidence so far: we have an article from a respected source, echoing Senior Product Marketing Manager Marc Diana in saying that PS4 implements their hUMA architecture while the XB1 does not. This is followed by the deduction that PS4 will have a significant performance boost over XB1 because of that. It remains unclear what the AMD representative said verbatim. We can only say that c't is as reputable as it gets in the space of German IT publications; that does not make them infallible, of course. In addition, Sony is part of the HSA consortium while Microsoft is not. Of course, we don't know the political implications of such a membership which may play a significant role along purely technological reasons. Technology-wise, we can say with certainty that PS4 indeed is a hUMA architecture. Everything we have heard since the release from official sources, especially PS4's Onion/Garlic memory bus layout and the volatile tag on cache lines, confirms that. In addition, Sony has actually advertised this fact quite aggressively, beginning with the Havok GPGPU demo at the PS4 reveal. We don't know much what the Xbox One does beyond what the leaked documents tell us. And those are ambiguous and not very detailed. At first, it sounds unexpected for it to not support hUMA. Microsoft certainly has implemented a more custom memory system than Sony to manage its DDR3/ESRAM layout, including its DMEs. There is no clear indication about which features of a hUMA architecture might be lacking. Maybe not all memory clients and pools are cache-coherent system wide. The GPU does seem to have to flush its caches when it synchronizes with other clients. However, the article on vgleaks is neither very detailed nor clear, nor do we know if its author recited the original sources correctly. So the relationship between a hUMA feature set and the XB1 is unclear. Politics-wise, AMD certainly wants to push hUMA since it is part of its own upcoming end-customer products. This would be reason alone to champion the PS4 independent of what the XB1 does, since AMD won't profit from what Microsoft has done with its memory subsystem. Apart from that, developers at gamescom seem to acknowledge anonymously that the PS4 has a clear 3D-performance advantage over the Xbox One which is certainly a result of many factors, not least because of its beefier GPU and its straight-forward, high-bandwidth GDDR5 setup.Update 5: [QUOTE="benny_a"]Got a response from the author of the heise.de article. Edit: Article is accurate as it is presented. http://en.m.wikipedia.org/wiki/C%27t on the magazine that did the interview: [Quote=" "]c't Magazin für Computertechnik (magazine for computer technology) is a German computer magazine, published by the Heinz Heise publishing house. Originally a special section of the electronics magazine elrad, the magazine has been published monthly since December 1983 and biweekly since October 1997. [] The magazine is the second most popular German language computer magazine with a sold circulation of about 315,000 (as of March 2011; printed circulation: 419,000). With 241,000 subscriptions it is the computer magazine with the most subscribers in Europe.Update 6: The Verge reported back in June on all topics AMD and seems to have included the XB1, although we haven't, again, a direct quote.
That might sound suspiciously vague, but we spoke to AMD and it's actually true. The AMD chips inside the PlayStation 4 and Xbox One take advantage of something called Heterogeneous Unified Memory Access (HUMA), which allows both the CPU and GPU to share the same memory pool instead of having to copy data from one before the other can use it. Diana likened it to driving to the corner store to pick up some milk, instead of driving from San Francisco to Los Angeles. It's one of AMD's proposed Heterogeneous System Architecture (HSA) techniques to make the many discrete processors in a system work in tandem to more efficiently share loads.http://mobile.theverge.com/2013/6/21/4452488/amd-sparks-x86-transition-for-next-gen-game-consoles Update 7:Apparently, AMD's spokesperson was not supposed to say what he said, so AMD dismissed having said anything http://www.nowgamer.com/news/2052820/ps4_vs_xbox_one_amd_retracts_performance_comparison.html
During a recent Gamescom 2013 interview, an AMD spokesperson made inaccurate statements regarding the details of our semi-custom APU architectures. AMD will not comment on the Microsoft Xbox One and Sony PS4 memory architectures and will not speak for Microsoft, Sony or other AMD customers.AMD PR[Quote="WICKED"]Update from the Heise author: He had a phone call with AMD and he says that they left open whether Marc Diana's statements are true or untrue. He also says that AMD made pretty clear that they're not allowed to talk about PS4 or Xbox One "AMD ließ auch während eines Telefongespräches offen, ob die Behauptungen von Marc Diana der Wahrheit entsprechen oder nicht. Besonderen Wert legte das Unternehmen vor allem auf die Aussage, dass die Firma keine Aussagen zu den Produkten seiner Kunden treffen darf also auch nicht zu Sonys Playstation 4 oder Microsofts Xbox One." http://www.heise.de/newsticker/meldung/Gamescom-Playstation-4-bietet-Unified-Memory-Xbox-One-nicht-1939716.html

[QUOTE="R3FURBISHED"][QUOTE="BoxingandGaming"] Its insane how you believed that false rumor from DF about PS4's ram allocation Yet this piece of info which has been PROVEN as fact you want to just dismiss If it hasnt been clear before you certianly made it clear now that you're nothing more than a hypocritical delusional xbot The PS4 uses hUMA and THAT IS A FACT. It gives the PS4 an even bigger edge in graphics. Another FACT Next time do the research before speaking. I will make it easy for you. Read this http://www.gamespot.com/forums/topic/29441181/3d-performance-of-ps4-much-farther-ahead-of-xbox-1-than-some-have-expected-?msg_id=341384489#341384489BoxingandGaming
I hate humoring alt/troll accounts - http://www.pcper.com/news/General-Tech/Sony-PlayStation-4-PS4-will-NOT-utilize-AMD-hUMA-Kabini-based-SoC
UPDATE: AMD contacted me again to make another comment. Essentially, they said that the correction statement to the original statement claiming hUMA was part PS4 was "inaccurrate" but that this correction does NOT mean the opposite claim is true. Even when pressed for a more specific and debate-ending comment, AMD wouldn't give us any more information.
So does the PS4 have support for some type of heterogeneous unified memory? Maybe. And the Xbox One? Maybe. At this point, I'd stop listening to anything AMD has to say on the subject as they are likely to recant it shortly thereafter. Many readers have emailed me with their thoughts and I personally feel that its more likely the original statement from AMD (that the PS4 will have the edge with a hUMA design) will turn out to be the truth in the long run...
You are so clueless. Of course AMD is going to try and deny it. Microsoft is a partner too. AMD gave your typical PR response so as not to upset any one etc Thats ALL that is.This is the last time I will reply to one of your posts:
There is nothing to report on this matter. AMD will not give a definitive answer, nor will Microsoft or Sony. Therefore, you have no point. When I first made this thread back in June it was meant as a resource for facts supported by reputable sources, preferably the creators themselves.
You can throw out all the cookie cut posts you want, but until you actually have a direct source saying one way or the other...you have nothing.
