    Digital Foundry Article Technical Discussion [2020]

    I wonder if this all relates to the PS5 120hz thing. If the 'performance' OS setting mistakenly enables 120hz - do the other 2 settings do anything they're not supposed to?

    Digital Foundry Article Technical Discussion [2020]

    I think camera motion in those "cinematic sequences" would look weird. More generally, VRR works better at higher framerates - below 60 it may not be all that effective.

    Current Generation Hardware Speculation with a Technical Spin [post GDC 2020] [XBSX, PS5]

    MS/Sony wanted to run BC titles at 'twice the performance' - a cache-based solution couldn't reliably achieve that. However for a theoretical 'pro' edition PS5/XSX then this type of memory solution would seem relevant.

    Playstation 5 [PS5] [Release November 12 2020]

    AFAICT that DDR4 chip sits next to their SSD controller. So I assume it's related to that (caching/decompression related?).

    AMD: Navi Speculation, Rumours and Discussion [2019-2020]

    From a quick google - memory bandwidth of a random Zen 2 processor is only around 60GB/s. Noticeable, but dwarfed by the bandwidth requirements of the GPU (where I think Navi 21 should require ~1.8x the bandwidth of the XSX?).

    AMD: Navi Speculation, Rumours and Discussion [2019-2020]

    I suspect the XSX only actually needs that bandwidth for XB1X BC. - the XB1X had 326GB/s of bandwidth. (vs a paltry 218GB/s on the PS4 pro) - a focus of the console (or PR focus anyway) is 'better BC' - doubling title performance to 60/120fps etc. - if RDNA2 is using cache/compression to make...

    Playstation 5 [PS5] [Release November 12 2020]

    At 4:33 the reverse of the shield - it looks like there are 8 white 'things' that rest on top (or float above?) the 8 capacitors? But I don't know what that is (plastic/compound/magic dust?)

    AMD: Navi Speculation, Rumours and Discussion [2019-2020]

    Lol. But the application was filed in September 2019, so it seems to be an actual thing. Edit: 2020 actually, doh!

    AMD: Navi Speculation, Rumours and Discussion [2019-2020]

    There are a few possible answers, the simplest one being that they are 'recommending' 20 CUs are used for this. Another option that their dynamic shared cache-thing scales up to 20 CUs (which is described in the patent as L1, but mentions in an off-hand way that it can be applied to other...

    AMD: Navi Speculation, Rumours and Discussion [2019-2020]

    AFAICT this would provide a psuedo-fast memory pool *if* you can ensure that [dataset size] < [number of CUs on task] x [cache per CU]? Which seems interesting - as it means that the optimal dataset size would be somewhat proportional to the number of CUs on task - which seems to suggest that...

    Nvidia's 3000 Series RTX GPU [3090s with different memory capacity]

    That's how VRS is used in VR. Outside of VR, it doesn't use eye-tracking - there's a DF video on the topic:

    Nvidia's 3000 Series RTX GPU [3090s with different memory capacity]

    As far as I can tell, the console platforms are intending to use VRS. However VRS seems to be ?somewhat incompatible? with DLSS - which may create a mess on PC.

    Xbox Series X [XBSX] [Release November 10 2020]

    Ah -ok. Although weirdly they do have images of the XSX and a short talk about the XSXs velocity architecture in the middle of the video /shrug. I guess another video might appear for the XSX UI/OS to show off any next-gen bits.

    Xbox Series X [XBSX] [Release November 10 2020]

    The clapperboard in the video has a date of June 29th. So it's quite likely that this video was finalized before the whole 'Craig' thing became a meme. But personally that video was not at all what I was expecting: - I was expecting to see the UI in use on XSX. Other than a boot animation...

    Xbox Series S [XBSS] (Lockhart) General Rumors and Speculation *spawn*

    I'd assumed that the concept is: XB1X -> XSX XB1S -> XSS So I'm not sure that customers are supposed to associate the XSS with the XSX exactly. They are consoles of the same generation, but the XSS is primarily the 'next-gen' XB1S.
