    Considering how their entire keynote was focused on connectivity, media, teleconferencing, and how long it can playback video on battery, I guess, yes? Maybe. It would be shame if it doesn't. Big shame. I am afraid it will not have it :/
    I am also afraid of that..

    You can cut off ~15% watt by using PicoPSU directly from your battery. But thread carefully.
    Yeah mate I was looking at smaller PSU's, but the cost was phenomally expensive. I could have just bought another battery to offset the 'savings'....so I did. I have two =D

    I'd prefer simple DC-DC PSU's, but yeah. A topic for another day. There's a whole host of optimisations I could do of course, but work-work.

    I'm not turning off anything. Sacrifices must be made!

    Seriously though, these thing's are pretty nice to play with. Poor old nVME though is waiting around sometimes. Never thought I'd see that!

    I don't suppose you would know if there's a retail/commodity version update to the 3xxxG series on the AM4 socket pending?

    As you probably saw, this case is 1.4L. However, it looks to have much better convection than most NUC-likes and is aluminum. I doubt there exist mini-ITX cases much smaller. Also, I think 120 W should be a decent amount of headroom for the turbo boost of 65 W APUs.
    There are a few mini-ITX cases which look sort of like the Mac Mini. I'm tempted to order the one that looks most promising, and get hands and eyeballs on it before buying anything else to go in it...

    I specifically went for the 68Wh option. It's weight is more than 1.6KG which is on the heavy side from my perspective, my previous work laptop was a Macbook Air 13. It's also much louder, but I'm very happy with it considering I can actually run heavy workloads in minikube. After more than 2 years worth of daily use it's now sitting at 48Wh. I used to be able to stretch to 8 hours, but now it's just over 5 in an ideal workload.
    running 5 hours on 40Wh will give 8+ if the battery was 68 - so seems that 4700U consuming about the same on our laptos. Before that I used to have LG gram on 8th gen intel and 72Wh battery - that easily worked for 12-14 hours in office-web load with decent brightness and wifi-bt on. so seems that 14nm intel is much much better in terms of battery than 7nm AMD. So I am still wondering how all that "reviews" appeared on the net claiming that AMD is the same or even better in terms of battery life. What I see it is a way worse, latest 7nm AMD eating battery almost 2 times faster than old 14nm intel.

    How long does it survive on battery? As I've seen the detail your model can have 40, 51 or 68 watt-hr options - so it is also important to know which battery you have. My Inspiron 5405 have 40 wh battery which is too small but Inspiron 5401 (almost same dell but intel-based) have same 40wh but lasts way longer (5hrs on amd vs 8 on intel)

    My mistake. I've been lagging behind, even RDNA1 is using GDDR6! This will be a huge improvement from my DDR4 based Vega8.

    some smaller notebook parts are 192bit GDDR6+128MB 12nm Infinity cache

    just to make a comparison

    "256bit GDDR6+128MB 12nm Infinity cache" means the performance of "GDDR6X, 1219MHz, 384bit, 936GB/​s "
    I need to read about this more. I remember reading about memory compression in RDNA2 but have not read anything about infinity cache on the GPU.

    Strange. I had a 3200G in a mini-itx M/B with a Radeon 560 and my system struggles to reach 140W. I played PUPG on it for about 6 weeks while I waited for a new CPU. I measured it at the wall (230V AC) so the DC reading will probably be ~15% lower.

    there is no big difference betwen a Nvidia 3090 with GDDR6x 384bit and a 6900XT with 256bit GDDR6+128MB 12nm Infinity cache
