    I have not followed these games closely enough to contribute something but it would not surprise me.
    Of course it's different from case to case. In some games the differences in texture quality are larger and in some they are smaller.

    Scropio could benefit from the larger memory.

    yeah I'm aware of that...my point was merely that checkerboarding/checkerboarding-like technique was used before PS4 Pro came along..

    wondering if they are waiting for RX580 to release...even though they could do the same thing with RX480...

    Looks like we're back to a drought of information for a while. These threads have been a little dead since there is no new info to speculate/debate on.

    They waited a year to get:

    6 TF vs. 4.2 TF
    2.3 GHz vs. 2.1 GHz
    326 GB/s vs. 218 GB/s
    12 GB vs. 8+1 GB
    HDMI 2.1 VRR vs. HDMI 2.0
    And 60 customization in the hardware silicon to reduce bottlenecks that they profiled from actual games
    And streamline their development toolkits
    And lastly to get the cost down to their target point
    And all of these are gambles

    MS could have followed Sony into 2016 but they would have exactly what Sony had unless that's all PR talk.

    You do realize that Sony also once paid for DF accommodation on the PS4?

    What is inferior about this?

    6 TF vs. 4.2 TF
    2.3 GHz vs. 2.1 GHz
    326 GB/s vs. 218 GB/s
    12 GB vs. 8+1 GB
    HDMI 2.1 VRR vs. HDMI 2.0

    Sorry there's nothing against blower type fans. Blower fans by themselves are not a bad thing but they become bad when they make a jet engine sound in certain games in the PS4/PS4Pro. The XB1/XB1S however remains much quieter.

    Hard to tell without knowing if MS had planned to have 2xFP16 and ID Buffer in 2016... Since we don't even know for sure what they have now, I would wait for more information before assuming their plan was that similar. Chances are slim.

    The motherboard layout looks like a rushed design with power transient issues solved with brute force (all xbox m/b do, but this time it's insane, it goes to 11). My guess is that they changed course very late in the game, and mostly changed the clocking, not the technologies in the SoC. Leading to a 2017 launch with 2016 tech. The 384bit memory was a given from the start, since they can't emulate the esram without it. Everything except the clocking could have been done in 2016 for a reasonable cost. It could be the same SoC for all we know.

    Just one hypothesis among others...

    Mr Fox yes.... Exactly my impression. Overclocked older stuff than ps4pro (as it seems fp16x2 not integrated). But The the 384bit memory bus will give anyway good results IMHO... but not dramatically different from ps4-pro (that is going to be the budget Sony console). At least MS could have launched at TMSC 10 nanometers. I think will see a very quite & smart ps4-pro at TMSC 10 nanometers in the end of 2018.

    Finally the article is released...

    A bit of a shame on the DR FP16, but using the 30% improvement developer number (from sebbi I think?) should still place the Scorpio above 4Pro given the 42% higher 6TF over 4.2TF specs.

    EDIT: It's unclear if the 30% improvement is from just using FP16 over FP32 or if it's from using Double-Rate FP16 over normal FP16. So the improvement might apply to both.

    The details of the simulation process are interesting, as is how much of that time was spent on insuring full BC with Xbox One. Sounds like the bulk of the development effort for Scorpio was spent on making the required development process for Scorpio as much like, "Do what you're already doing, but when you get to the end hit the '4K' button instead of the '900p/1080p' button." as possible. Then it's up to the developers to determine if it's worth putting in more effort than that.

    The increased memory bandwidth and capacity also matter. Devs will be able to achieve similar results with PS4 Pro as they will with Scorpio, but they will have to work a bit harder to get them.

    Lack of double rate FP16 is curious. Also closes the performance delta potentially. What with this and the ID buffer, it'll be very interesting how the two system compare. VRR certainly makes Scorpio the choice of the elite gamer though.

    Mid gen boxes ended up being a lot more interesting than we feared! :D

    It lacks Double-rate FP16 not FP16 support all-together. Xbox One and PS4 where GCN2 based and didn't have support for single rate 16Bit ops which was introduced in GCN3 and supported in GCN4 (which is Polaris..thus Scorpio has is). PS4 Pro in addition supports Double-rate 16bit ops which will be part of GCN5 (Vega).

    It is not lack of fp16, fp16 is available on AMD GPU since Tonga. It is lack of dual fp16.

    And fp16 without dual fp16 is a good things at register level.
