    Not sure we had a clear shot and I've not noticed it on the retail teardowns.

    Also, GDDR on the back, so 5x 2GB chips?

    Yeah, I think that was semi-confirmed when initial shots were released. They seem to have clamshelled the 4th and 5th chips in order to hit the 10GB on the 128-bit bus (3x32-bit + 2x16-bit)

    I suppose they'll eventually replace that with a single 4GB chip when they become available for a tiny cost saving.

    That's (almost) exactly what they're doing, according to this DF article back in September. Original Xbox games should run at 9x (1920x1440 for 480p), and enhanced 360 titles should run at 4x (1440p for 720p).

    Some more Watch Dogs ray tracing on Series S while we wait for DF to stop being just lazy journos. ;)

    It doesn't look bad at all at 3m away on a 50 inch TV.

    We've known for a while the custom SSD in the Series X/S is PCIe 4.0 x2 (2 lanes), effectively getting the same max performance as a standard PCIe 3.0 x4 NVMe drive.
    So while you can put a >7GB/s capable SSD in there, the interface won't support more than the 3.94GB/s (practical 3.5GB/s) speed the x2 connection allows for. I think you would lose performance if you got a PCIe 3.0 x4 drive there though (assuming the OS would allow it), since it would only work at PCIe 3.0 x2 for around 1.8GB/s performance.

    But even if you found a 2230 sized PCIe 4.0 SSD that provides 3.5GB/s on 2 lanes of PCIe 4.0, I doubt the I/O hardware would make use of more than the standard 2.5GB/s raw throughput it's been designed around.

    Some have tried putting standard Samsung M.2 2230 NVME in there and it didn't work. Many suspect it's because of customized firmware.

    Well, maybe xD. MVG confirmed it was a retimer chip from the XBO, so it's nothing that'd enable BC in a hardware-based sense. Though that shouldn't be surprising for anyone; MS've already said multiple times their BC is emulation-esque. They wouldn't need XBO CPU, GPU etc. to accomplish it.

    OTOH we know Sony's is hardware-based but I'm assuming that's through configuring microcode on the GPU to simulate GCN (are they doing similar with the CPU?) and the whatnot.

    Maybe they should've...confirmed their information before running with the story in the first place? The things some of these websites do for clicks, it's like journalistic integrity doesn't exist.

    Maybe, but then they need a large table of id's as I've seen at least 4 different NVMEs from Series X and S teardowns. Some were Western Digital, some were Solid State Storage Technology Group, some where SanDisk, and the externals are Seagate. *shrug*

    EDIT: Though I wonder if they tried to clone the partitions and filesystems and MBR and GPT exactly. Maybe they weren't as meticulous about it as hardware hackers like us would be.

    Crikey.

    hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm


    -------

    Oh nice. They included a die shot of Lockhart there. It kind of just reminds me of a typical AMD APU.

    :p

    -----

    Confirmation of 8GB available to devs on Lockhart.

    The XSS was the right decision.

    Yea its what i've been saying for awhile. You can see it in the xbox one / ps4 generation the consoles didn't really get under $300 even over 7 years of time.

    Xbox series s / x will give way to new consoles designed for their price points with new hardware.

    Man, it was a tongue in cheek comment

    The chip has nothing to do with backcompat, It´s indeed the southbridge, for comparison this is the Xbox One S southbridge

    part number X861949-005 T6WD5XBG-0003

    It´s strange that they didn´t change the xbox one marking in the Series S southbridge :rolleyes:

    Has anybody teardown a Series X yet?

    They probably have millions of leftover chips from all the Xbox One SAD Edition consoles that didn't sell.

    I'm still curious if MS will nail down the production allocation balance that best suits demand for both models, knowing these two systems are sharing production budgets for manufacturing, assembly, shipping & handling etc. But so far it seems they have a pretty good handling on that.

    It was my biggest worry for a while actually because I got over the whole "it'll hold next-gen back" nonsense rather quickly (and with WD:Legion results on Series S I don't think that concern really flies anymore), but matching production budgets to both systems in line with expected levels of demand, that could always be a challenge.

    depends on die size , i think MS can make 3 xss apus per xsx apu. So they shouldn't have a real issue meeting demand.

    That was an interesting interview, but this bit stood out. The reason they kept support for the base XBO-S instead of the XBO-X.
    • XBO-X is too expensive to justify being at a price point that represents the bottom of the console stack.
      • This was expected.
    • They want to have the previous gen feature set disappear as quickly as possible without abandoning people that cannot immediately get a XBS-S/X. Continuing support for the XBO-X would have meant that the previous gen. limitations would potentially linger far longer into the current generation as it's a more powerful and capable machine.
      • Makes sense, I didn't think about it from this angle before.
    Regards,
    SB
