    Why don't tablets/smartphones use dc dimming?

    Posted: 26 Sep 2021 07:46 PM PDT

    I know of a few phone's that offer the option, but not a single tablet has it as far as I know. Why?

    iPad pro 11 2021 pwm/flicker?

    Posted: 27 Sep 2021 02:21 AM PDT

    Very sensitive to this so checking a lot of information.

    The notebook check reviews are all over the place. They find significant flickering in the 2020 ipad pro 11 and none in the 2021 version, while the screens are essentially the same. Than in another article they do mention flickering.

    Was considering a Samsung tab s7 as lots of people report it being easier on the eyes, but again, there's conflicting reports regarding pwm flickering.

    The tab s7 seem extremely underpowered compared to the m1, and I'm prepared to pay the premium, but only if the screen is better on the eyes. Thank you

    AMD 3D V-Cache 15% figure source?

    Posted: 26 Sep 2021 11:15 PM PDT

    The only source I've found is a 5900X with 192MB of L3 cache tacked on via 3D V-Cache. Yet many people seem to think the Zen 3 refresh has V Cache and V Cache = ~15%, so Zen 3 refresh == ~15%

    Are people actually expecting the entire Zen 3 line to come out with 192MB of L3 just because die stacking is a thing? Or have people just confused a specific configuration in an engineering demo with a broad picture of what V-Cache will add to Zen 3?

    To me, in a silicon shortage, 192MB of L3 even for a 5900X seems pie in the sky, let alone for the entire range... so is there another source people are getting this idea from?
