    Assuming the ram is single channel, for a device this small.
    I had a misconfigured renoir laptop that was single channel. getting the supplier to set it up dual channel gave a SIGNIFICANT increase in performane. I recorded 78-85% higher framerates from the IGP than before, and that IGP was weaker than this one.
    So I'm pretty sure they used dual channel as the RAM is soldered straight on the motherboard, else this thing's performance will be abysmal.

      Yup, this is probably number #1 on the charts of the top idiotic things system integraters can do with PC's, they ship it with a single stick of RAM. Even if you have a low amount of ram like a single 8 gig stick its always better to instead ship 2 4 gig sticks.

        That is very nice! Especially the move from Debian to a closer to the edge distro is a fine idea. Steamos is/was a good idea but to slow because of a lot oft outdated drivers and libs. Especially considering that they sitick to older releases.

        The only question how is this going to influence their toolchain?
        All the proton runners build sdk's solider helper whatsoever are built around debian (some ultra old Ubuntu 12.04)
        Just digg through the proton build scripts. Sure steam runtime will be AFAIK still standalone and not so much depending on system libs so crossover compatibility might not be very necessary.

        I was hopeing for a clearlinux fork adjusted to AMD. But the risk is to high that it one day will break on AMD. And the media codec support is rather bad e.g. for ffmpeg you have to rely on 3th party repos.

        None the less they should use the xanmodkernel. It uses also some cl patches and is a very good gaming kernel.

          These devices are looking good and with the global gpu shortage I think it will sell quickly.
          Increased availability of 4000/5000 APUs later this year. The 5000-series desktop APUs will hit retail on August 5th.

          GPU prices are coming down and the whole situation will be improved around Q1 2022.

          A 6000-series Rembrandt desktop APU may be the one to wait for. If the Van Gogh APU in Steam Deck is up to 1.6 TFLOPS, I expect to see up to 3.5 TFLOPS in the top Rembrandt. That's assuming they can get 12 RDNA 2 CUs to 2.3 GHz.

          The APU is known as "Van Gogh". It's not necessarily customized for Valve, but we'll have to see if it comes to any products from other companies. It will be followed by "Dragon Crest", a refresh likely with the same specs.

          LPDDR5 is different from DDR5 in some ways. Should be a great choice for this APU though.

          It's 100% bad for people who don't know any better, as it causes a huge performance loss for no obvious reason. It might be great for some people. For example, there were some HP Pavilion 5700G systems earlier this year that shipped with a single stick of 16 GB. You buy and put in your own 16 GB stick, boom, you have a cheap upgrade to 32 GB with no leftover stick.

            I want one. This is a dream machine for playing some games on my bed. And based on Arch? AWESOME!

              It can run Crysis.

                I've been running proton games on arch for a while no problems in that department. I did find other issues like dbus compatibility problems but no proton/build tools related things.

                  That thing looks pretty cool. Also I love how they weren't stingy on the RAM. 16GB. That should allow pretty much any PC game to run on it. Sweet device.

                  And unlike the Steam Controller, this thing will have a proper plus-shaped D-pad. 😍 Thank you, Valve!

                    The only thing I think I miss that would have made the device perfect is if it had an OLED screen like the new Nintendo Switch Pro, that would put the device in a league of its own (even if it is only for the higher tier variants).

                    Once you go to OLED you cannot go back
