System to boast 50GB Blu-Ray disc drive, more.

Video game leaks website VGLeaks has posted what it claims are specs for Microsoft’s next-generation Xbox, codenamed Durango.

First, the “system block diagram”:

Next, what’s “inside the box”:


  • x64 Architecture.
  • 8 CPU cores running at 1.6 gigahertz (GHz).
  • Each CPU thread has its own 32 KB L1 instruction cache and 32 KB L1 data cache.
  • Each module of four CPU cores has a 2 MB L2 cache resulting in a total of 4 MB of L2 cache.
  • Each core has one fully independent hardware thread with no shared execution resources.
  • Each hardware thread can issue two instructions per clock.


  • Custom D3D11.1 class 800-MHz graphics processor.
  • 12 shader cores providing a total of 768 threads.
  • Each thread can perform one scalar multiplication and addition operation (MADD) per clock cycle.
  • At peak performance, the GPU can effectively issue 1.2 trillion floating-point operations per second.

High-fidelity Natural User Interface (NUI) sensor is always present.

Storage and Memory

  • 8 gigabyte (GB) of RAM DDR3 (68 GB/s).
  • 32 MB of fast embedded SRAM (ESRAM) (102 GB/s).
  • From the GPU’s perspective the bandwidths of system memory and ESRAM are parallel providing combined peak bandwidth of 170 GB/sec.
  • Hard-drive is always present.
  • 50 GB 6x Blu-ray Disc drive.


  • Gigabit Ethernet.
  • Wi-Fi and Wi-Fi Direct.

Hardware Accelerators

  • Move engines.
  • Image, video, and audio codecs.
  • Kinect multi-channel echo cancellation (MEC) hardware.
  • Cryptography engines for encryption and decryption, and hashing.

These specs seem to comply with previous rumors of the Next Xbox having 8 gigabytes of RAM, with 3 gigabytes reserved for the operating system.

VGLeaks promises a similar reveal for PlayStation 4, codenamed Orbis, soon. Be on the look out for that.

    Lol xD i think my laptop is stronger, ok jokes aside i really want the next gen xbox and playstation! Well playstation 4 would be nice to have :D

    • If you have a really high end alienware laptop with a 7970m chip, then it might be. If it’s a 78xxm core, then it’ll be about the same graphics wise.

  • Kou

    These are like the minimum requirements I’d put in a budget PC ..I still hope it ends up being stronger.

    • zakou

      What you need hopes for is not if it becomes stronger but if we will get epic games for it. What we have learned from the history of gaming is that no matter how strong or weak a console is, it can still get games x10s better than x10s stronger PC’s.

      You can ignore specs but you can not ignore this: Final Fantasy, God of War, Tales of, Uncharted, Bayonetta, Tekken, Disgaea, Gran Turismo, Street fighter, Blazblue, Naruto, Ninja Gaiden, Monster Hunter, Kingdom Hearts, Metal Gear Solid and the endless list goes on.

      All you need is developer support, i know some developers like Epic want super big specs for Gears of War 4 or 5 but most of the developers will make godly games with shitty specs ^^

      • I’m not sure about 10x the performance, but they definitely manage to squeeze out enough for 2x the power of a PC with identical specs by the 3rd generation of games. I’m sure we’ll be perfectly happy with the graphics quality of these new consoles for 4-5 years after their release.

        • zakou

          xD my bad, what i meant was x10 better as in, “x10 better than PC games except graphics”

          But sadly we can’t play “graphics” themselves so yeah imo console games even with shitty specs compared to PC that is almost always x10s stronger than consoles, they still end up having more fun, story driven and overall better games “imo”

          And my laptop is i7-3610QM with HD graphics 4000 in it, i know its nothing specials as a GPU but i can play almost any game on medium on 60 fps or high on 30 frames per sec.

          • HD 4000 is really no match for either of the new consoles, which use 7850m and 7970m level graphics chips if the rumors are accurate. I recall that it’s around 1/4th to 1/6th as powerful as the 7850m…

            But it is true that I’ve enjoyed console gaming much more than PC recently. Particularly the PS Vita, which isn’t really anywhere close to as fast as my PC.

    • HeatPhoenix

      8 cores? wha?! That’s anything but budget.

      • 8 cores, but they’re not high end cores like a i5 or i7. They’re probably 2-3x as powerful as Intel Atom cores. That’s no big deal though, I’m sure they’ll be more than sufficient for console use.

  • Prodigy-X
  • Rafi

    To be honest next PS and Xbox need to kill loading time or make it quickly as possible with more L2 & L3 chace on the CPU with SSD Sata 3.0 rather than HDD, it still rumor but maybe it will be different in final product specification.

  • 浪黒雷 (ro-kurorai)

    Couldn’t care less. The Last of Us, Uncharted 2/3, Beyond: Two Souls, God of War III, Heavy Rain, Killzone 3, Journey, Ni no Kuni and Halo 4 are each a very convincing case in point for meager specs being irrelevant to top-tier exclusive studios ( ̄▽ ̄)

    Still, if the new machines can maintain 1080p60 output in each game then I’m more than happy. When I take a look at the games mentioned and the ones in the pipeline (esp. Beyond and The last of Us) my mind boggles how those devs can squeeze out that much out of 6 years old hardware running with a paltry 256 MB of RAM. I think my brain will explode if I try to imagine what the top tier studios responsible for the games I mentioned can concoct on next gen hardware *drools*

    • 1080p at 60fps seems like a good bet, if they aren’t pushing the graphics settings too hard.

      • 浪黒雷 (ro-kurorai)

        Well, running on consoles sporting that horsepower I would honestly be disappointed if devs could not achieve it, especially as they’ve been working with current console hardware for over 6 years. 1080p is really just 50% more pixels to push on screen. Double the frame rate is a different beast but the latest 720p60 games look nice already. At least MGR looks damn fine to me.
        I’ll be seriously disappointed if 1080p60 won’t become the new standard.

        • I hope you’re right, but I do know that there are studios out there that always target 30fps just so they can make the scenes look as beautiful as possible.

          I always appreciated that Insomniac took a small graphics hit so they could do 60fps though, and that other studios did the same.

          • 浪黒雷 (ro-kurorai)

            well, given the majority of studios could achieve relatively stable 30 fps (unless they were Sonys’s/ MS’s top studios who always deliver v-synced 30fps) I’m very optimistic for 1080p60 being the standard on each game. the new machines pack some serious horsepower under their hoods. would be a shame if only a small select few elite devs could tap into that potential.

  • doubt it who cares specs are irrelevant

    • ShinAsura

      Specs are relevant, they help to shape what a developer can and can’t do with the games they’re working on

    • Zohar127

      Gotta agree with Shin here. There are countless examples of games that do amazing things that simply weren’t possible on previous gen hardware. That doesn’t mean that you can’t make a good game with a low-end machine, just that more processing power means the developers have so much more freedom.

  • Nothing here really surprises me. This pretty much matches previous rumor based reports.

    I’m still interested about the disc drive. I wonder if they decided to go the Wii U route and use a proprietary based disc or not?

    I’ve talked about my thoughts on the next gen already. I’d just be repeating myself If I posted the same stuff again.

    I will say this much, it’s important to remember that a dedicated gaming box has some advantages over PC. It’s not as simple as comparing hardware and being able to tell what developers can do with the improvements. We have to wait and see how developers utilize the new hardware.

    Look at what studios have been able to create on the current hardware. Think about how much better engines will run without so many limitations.

    You also have to factor in production costs, along with how much power the consoles are consuming. It’s not the same as building a custom gaming PC for yourself online.

      But it’s a state of Mexico.

  • ShinAsura

    Are the hard drives SSD?

    • Rafi

      No, the simple thing is HDD is much more slower speed at write or read I/O data but much more cheap price than SSD. If want to know more deep and complex just ask rockman29, he/she is one of the Gematsu family.

    • It doesn’t really go into detail above. It just says hard drive is always present. Which is a good thing! Still consoles being sold today without one.

      SSD support is possible, but I would be surprised if a console shipped with one in the unit. Despite the prices of certain drives lowering, it would still be somewhat expensive to mass ship a unit with a pricey SSD.

      How would they balance the cost? What about making a unique SSD that would better support a console? (We can’t be for sure the new consoles are being designed to better support SSD.)

      I’m sure a deal would have to be drawn up in order for it to happen. Most likely Sony or MS would agree to a deal, let’s say with Crucial for example. Make us a special SSD for our new console. They would probably negotiate a deal so the cost of the drive itself was not so high. In return, Crucial might get a big check or some % of sales.

      It just stands to reason that putting an expensive drive into a console will likely raise the price of it for consumers. That is probably the biggest factor. How would Sony or MS balance that out, etc.

  • ShinAsura

    Are the hard drives SSD?

  • The rumors are that the 8 core chip is based on the AMD Jaguar core, which is a more advanced version of their very good Bobcat core commonly used in low end laptops and some tablet PCs. While it isn’t the greatest chip for PC use, it’s way more advanced than the core on the 360 and the PPC core of the PS3. Of course, the next playstation is rumored to have the same 8-core Jaguar chip as well, with some extra APU GPU cores added to it. Should be interesting. Both systems should be much cheaper on the power bill to run as well than the ps3 and 360 launch consoles. Think less than 200 watts.

    • Right. This should also help fix overheating issues, which has been a problem worth mentioning with this console generation.

      As for the 8-core chip. I’m pretty intrigued by it as well. I’m also interested to see how both consoles tweak things, along with memory clock settings and such. Like I mentioned in my post below, a dedicated gaming unit does have advantages, even if the hardware is the same in a PC. You have windows and other things that can slow things down.

      If you built a gaming PC, you would want more power all around, which would also require a beefier power supply. I have a 1000w psu in my PC, and I can’t really even begin to imagine a console getting remotely close to that level. Something mass produced that runs that hot, it would be risky all around.

      I brought that up because of the upcoming steam boxes from Valve. I’m quite interested to see what they do. Most graphics cards are quite power hungry, many of them use just as much as the new consoles might use, and that really says quite a bit. (More than likely, they will be releasing something with comparable specs.)

      I think the power is worth mentioning in regards to new consoles. Some people ask why the new consoles don’t use this specific card, or this chip. It’s about finding the right balance.

      • Yeah, the most power hungry console I know of was the launch PS3, which had a 380watt power supply, and used around 290 watts on average. The Xbox360 also used quite a bit more power than older consoles. Those are also the two consoles that had the most issues with overheating chips bricking consoles. I think they’ve both learned their lesson and are going with more modest hardware.

        Still quite powerful in absolute terms, but both of them are using laptop graphics chipsets and CPUs built for low power consumption. (Bobcat 1.0 used around 9 watts per core and the Jaguar is more efficient than that.)

        From the hardware shown so far under the idea of Steambox, they’re shooting for sub-200watts for those as well. I believe the xi7 that the company was showing at CES was quoted at less than 65 watts. That would put it at around the same consumption as the PS3 Slim console.

        • “From the hardware shown so far under the idea of Steambox, they’re shooting for sub-200watts for those as well. I believe the xi7 that the company was showing at CES was quoted at less than 65 watts. That would put it at around the same consumption as the PS3 Slim console.”

          I had not read about that. Impressive. (Thanks for the reply.)

    Rumor: Next Xbox to be able to make coffee while doing your homerwork! x P

  • Raiyu

    What surprises me the most is the HDMI In

  • KurisuMakise

    So it’s looking to be official debate wise, 4GB GDDR5 vs 8GB DDR3 with 32MB EDRAM… Sony and MS clearly are showing where the strategies are concerned. Sony going for the minimalist OS setup, in order to concentrate on core experiences (Movie playback, Games primarily, most probably other easy to peg features). Whereas MS clearly are thinking about services which require a bit more RAM. Perhaps the return of things like 1 vs 100, or full skype integration.

    Pick your poison and join the trains, the next gen is going to be interesting.

    • Zohar127

      Yeah I’m a little concerned about the rumors that the Durango OS will require or at least have access to 3GB of RAM. On one hand it could mean it’s chock full of awesome stuff. On the other hand, it could mean I’ll have my Dashboard populated by a crapload of non-gaming crap I don’t care about.

      I believe 4GB of much faster RAM is better than 5GB of slower RAM, so I’m giving the PS4 the edge in the RAM department, assuming it’s all true, etc.

      • KurisuMakise

        I agree with you but I’m going to try and keep completely neutral this time around. I don’t think I want to buy all 3 again next gen, so I feel I should be choosy this time around. Do I want a beefier OS or do I want the faster experience in games…decisions will be made after things are clear.

  • PrinceHeir

    ehh im more into games, but it’s definitely exciting to see this :D

  • ddsfan2

    That sounds very powerful, provided that developers are actually really good at writing multithreaded code to utilize all of the cores. Otherwise, development on a system like this will be costly and time consuming just like the PS3.

    A programming language like Erlang would be a great fit for development on the system, provided certain details of the runtime system are up to snuff, and if the garbage collector is sufficient for a AAA commercial game.

    • I think it’ll be a bit easier than the PS3 even without the multithreaded experience. You won’t have to do manual pushing of data around between the cores for one thing, and all of the cores will be identical. It’s just like developing for a PC with an 8 core processor and an AMD GPU.
