    so does this apu support av1 decode or not?

    currently I use Dell inspiron 5405 on 4700U Renoir chip. The imprressions are bad so far. To begin with - Dell removed S3 suspend from BIOS , and seems that is not only Dell's fault. Asus and HP also have only "modern" s2idle available, and s2idle is not supported by AMD on linux. The bug is there for 5 month (https://gitlab.freedesktop.org/drm/amd/-/issues/1230)- but no much imprpvement on that. I either goes to s2idle and never returns back ( or wakes up once and dies on second suspend) - or using about 5 watts of battery pretending that it is suspended. Laptop that can not suspend - useless, and no performance or other "bonuses" from AMD can not compensate this main laptop functionality. Battery usage is also bad compared to intel. There are many reviews on web claiming that Ryzen have better battery life but all of them for Windows. On linux - despite all the power saving configs in place I manged to squeeze 5 hrs of battery in light web browsing. 5 hrs in late 2020 - early 2021 - come on, AMD. In fact - it is not taking much more power when in active states, but when idle it takes way more. I had a chance to compare Dell 5405 (AMD ) and 5401 (10 gen intel) with almost identical config (in fact it is even possible to swap morherboards between those models) - and intel idles on 2- 2.5 watts while AMD 3.5 - 4.

    So from what I see AMD is a way behing Intel on laptop market for linux. Unless you use your laptop only on your desk and always pluged into power socket. I still believe that issues will be resolved soon and AMD will fix s2idle and psr (panel self refresh) which are not working on Renoir at all - so will keep this latpp for a while... But if not - that would be my first and last try with AMD no matter how great performance the internet reviews will show. For laptop battery life is the king, and 5hrs of battery for light web browsing in 2021 is nonsence.

    The battery life claims for the 15W zen3 based apus are pretty exceptional, they match the claims made by Apple for the M1 macbooks. If this is true and there isn't a catch regarding the performance, then this should be a slam dunk for AMD assuming they can produce enough chips for the oems.

    I don't understand this statement. I'm pretty sure no EPYC models fit that range of TDP. Also, the motherboard is going to cost you a lot, even looking past the CPU price.

    If you want a CPU in that range, I think that limits you to the 65 W Ryzen models, or else you have to go up to 105 W. As for official ECC support, get a Ryzen Pro, which means you'll probably have to buy the machine prebuilt (since they don't sell Pro CPUs in the retail channel DIY builders).

    I'd like a 5800U/5900HX based NUC clone.

    As chithanh mentioned, one big piece of news was that Threadripper Pro is no longer exclusive to Lenovo. The Pro variant is basically a single-CPU EPYC, with higher clocks and a 2 TB memory limit. Compared with the 3990X, it offers more memory capacity and bandwidth.

    Anandtech covered 3 new motherboards for it:


    As yet, no news on a 5000-series Threadripper. I'd imagine getting Milan (Zen3-based EPYC) launched is a higher priority.

    Well that show was disappointing.
    • Since Raven Ridge three years ago, there has been no substantial improvement to the APUs for the DIY market. (AMD doesn't want DIYers to buy Renoir.) This is approaching almost RS780 levels of misery.
    • Nothing about Van Gogh (will it come at Computex then?).
    • Nothing about Threadripper 5000 (even the announcement of Threadripper Pro 3000 coming to retail was hidden in the investor notice)
    • New graphics cards in 2021H1, which probably means Computex too.

    I remember differently. It was the Lenovo Ideapad 720S that was a total crapfest. Thermal throttling, only single channel memory, buggy BIOS, you name it. Yet it somehow saw constant marketing push behind it, and I suspect AMD's doing.

    Same with an HP 15 laptop, I remember the cringe-worthy advertorial from Notebookcheck. It was the embodiment of what was wrong with AMD laptops before that: Poor screen, runs hot, short battery life. Again, I suspect AMD was behind this too.

    Instead of promoting the preciously few good 1st gen Ryzen mobile laptops like the Huawei Matebook D, for reasons probably only known inside AMD's perpetually inept marketing department.

    Fingers crossed we see some reasonable portable workstation builds. i don't know why every laptop has to be a gaming laptop these days... And after the total lack of availability of their higher end lower power parts like the 4800U (thanks Lenovo!) there's a big gap waiting to be filled...

Instead I imagine ASUS and other companies with a greater performance focus will be in at the start again, and some decent systems will be in the market at mid and high end. There should be decent cooling, since the thermal requirements are the same as Zen 2, and while nothing stops buttheads using single module RAM on low end products, there are enough manufacturers that know better to ensure a decent range of choice.

    I expect the bottleneck here won't be vendor stupidity for once, but chip supply.
