Running The Open-Source Upstream V3D Driver On The Raspberry Pi 4 & Newer
Don't they use the same SoC? It only counts as "newer" if it's not the same as in the original Pi 4.
From what I can see, they all use the BCM2711, though the 400 uses a C0 stepping. It seems extremely unlikely that any significant design changes would be introduced in a stepping, rather than a new model number.
Product wise they are newer but you are right SoC is the same but the article mentioned Pi 4 and not BCM2711
So what drivers are still missing out of a stable-line stock Linux kernel then? When are you going to be able to just load up a stock version of Fedora and have every piece of hardware in an RPi4 supported?
And when can we expect to see decent support for ARM GPU-accelerated greaphics and video in a web browser (ANY web browser!) without a massive hit to CPU or janky YouTube H.264 hack plugins?
And when are we going to see the mass adoption of a standard firmware interface for ARM, like System Ready??? Cuz until then, ARM ain't ready...

I think the standard Pi 64-bit install now gets most of its packages directly from Debian repos, though there still is one Pi-specific repo.
I expect it will need something better, to avoid throttling. Perhaps we'll see. I never use the adhesive on those things. I clean it with isoproply alcohol and then use a PC-grade heatsink compound. As I discovered on the Pi 3, it still doesn't make up for using a crappy little aluminum heatsink, when what you really need is a big copper one.
Or this one, which is the biggest copper heatsink I can find that will fit:
It's 20 mm x 20 mm x 7 mm high. The white outline on the PCB is about 19 mm x 19 mm, but I figure there's no harm in putting it a little off-center or even crowding the RAM.
