    Would be great, like the launch PS4 having interchangeable covers, but the whole console this time.

    https://www.playstation.com/en-gb/explore/accessories/custom-faceplates/

    It would mean simpler stock logistics at launch versus having multiple console colors. Anyone can just buy the covers they want, or replace them once they're tired of the bright pink one they bought as a joke (or did they).

    Nice.

    Now, I just hope it would have changeable/cleanable case filters..

    Were custom faceplates on 360 and PS4 ever that popular?..I guess if you are changing the entire look of the console it may be more popular.

    I mean this way they can just release one version and if you want a black PS5 you just buy new faceplates...

    This article and the benchmarks are more applicable to PS5 since it's going to be mostly Kraken + Oodle Texture....

    https://cbloomrants.blogspot.com/2020/07/performance-of-various-compressors-on.html

    Interesting it's using 256K chunks as a supposed "typical" game usage. So maybe PS5 will also do 256K blocks which would be nicer on the FTL requirements, but OTOH it would require more expensive SRAM buffers on the hardware decompressor. It's hard to tell.

    Using large chunks improve the compression ratio. If they go for 32KB it would improve latency and IOPS, but compression would logically be worse. I am convinced they entire hardware pipeline would need to be designed with a fixed block size in mind, but we don't know what. I think it could be anywhere between 32K and 1MB.

    There are still a lot of question surrounding it, and I would hope DF will address it at some point. Maybe none of their contact want to say anything, or they can't corroborate this, or DF signed an NDA, who knows.

    The typical data of games will vary wildly, so will compression. But they can crank the lambda way above 40, it seems that lambda 40 is "mostly" imperceptible from lossless, some types of data like things with text might want it more lossless. Also we have benchmarks showing geometry will compress 3:1 on average with Kraken.

    Among the stuff that was in this admirably exhaustive list that stood out was the fact that the caches would be larger and something that would be shared with RDNA 3 that would line up with what Cerny said about making sure that the extra speed of the APU wasn't too debilitating WRT memory access and such.
    Larger caches for less cache misses and some form of comprehensive cache management looks promising if true.

    My question is why havent more ppl spoken about this...this seems like as much a next gen feature as anything else regarding what allows for ps5 overall considering sony set up paths for all devs to use it

    Oodle conpressor is limited to lambda 40 because above this they think the quality loss is perceptible by human eye.

    Is it never useful? I saw benches at 50.

    Oodle texture it seems in the tool they deliverd they limit it to 40 because they did tons of test and they said above quality loss is generally perceptible by human eyes.

    EDIT: Or maybe it is only an advice but they advice to limit lambda to 40

    Cerny said the Kraken decompressor can do 22GB/s peak for data that "compress particularly well" in the Road to PS5 presentation. When sony and oodles announced the partnership for oodles textures, which is basically one of many RDO tools helping textures "compress particularly well", it made a lot more sense to have the whole data path able to reach 4:1 compression at wire speed. We still need more info about real world data but the picture is much clearer now. Pun intended.

    speedstep is slow compared to renior , and this seems to be much faster then it

    Has this been posted?

    "Also as a free update for those who get WRC 9 on either PS4 or Xbox One, the game will upgrade to the next-gen versions on PS5 or Xbox Series X, and we're looking forward to seeing how performance, graphics, or features such as PS5's Activities feature (an instant deeplink to specific races directly from the console's menu) reveal the future of rally racing."

    Seems like the original Gamereactor article has been deleted.

    looks like a OS feature that wasn’t supposed to be revealed. If you can jump into a mission from the OS UI it would be great. Probably MS will copy it into their OS.

    Well there's a rumour going around that Miles Morales will come with a Spiderman remaster included. So a free upgrade? Confusing, A patch for everyone who already bought the game would be better, I guess.

    The system architecture supports ~1ms granluarity of frequency change* since Zen 1 SoCs, and it is marketed as a bullet point of the marketing feature Precision Boost.

    * as in the SMU reevaluates all the IP blocks' activity level and running parameters, and adjust their budget and in turn voltage and frequency on the fly

    Looks like Sony’s take on DLSS:

    doesn't mean jack.

    build a model that works, is lightweight and runs fast; that is where the IP is worth something. The technology portion is the least relevant portion of it.

    2ms is the number stated by AMD when it comes to Smart shift. I'd have assumed the things Sony added on top would've slowed it down, given their implementation also changes clocks while smart shift is moving around the power to each component.
    This rumor is just a rumor. Insomniac dev laughed at it. The translation is based on the idea that MM was just a DLC for the original game and should've said running on updated spider man engine rather than spider man update.
