Steam Frame, Steam controller and Steam Machine Revealed

And the PS6 and next Xbox will still get blown away by even by 4xxx/5xxx series GPUs. Plus, we're stuck with games that have to run on PS5 and Series X well into 2030… By the time that's over, a second wave of Steam Machines will probably be rolling in.
Will it be possible to change the GPU or add an external GPU to the Steam Machine?

For the handhelds, that's true, but I don't think Valve is ready for desktops.
They've expressed the same desire in recent media releases for steam machine. as long as the machine is AMD/AMD there is virtually no difference. Nvidia is a hurdle but that is also another thing valve can only work so quickly on without nvidia changing how they do things. At the end of the day it's just a Linux distro with gamescope. It's not really as special as people seem to think it is.

Special only in the sense that everything is done out of the box, but that is important. Whoever it comes down to doing the work, Nvidia is the roadblock right now for a lot of gamers. I've seen that expressed here many times from folks, including myself.
 
Good luck with FSR4 on a 35 TOPS GPU

There's a reason why AMD keeps it exclusive to RDNA4

RDNA3 doesn't have the hardware for it, let alone this 7600M laptop GPU

In the latest version of Proton, an automatic converter has been added to use FSR4 on other AMD GPUs.
However, according to the changelog, this feature is disabled by default, according to the developer, due to forces beyond their control. This suggests that something official might come in the future, either from Valve or AMD.

FSR4 support

We added support for AGS WMMA intrinsics through VK_KHR_cooperative_matrix and VK_KHR_shader_float8,
which is enough to support FSR4.
Note that these shaders are tightly coded for AMD GPUs with some implementation defined behavior
(particularly around matrix layouts), and they will not necessarily work on other GPU vendors.

There is also a quite hacky emulation path of this which relies on int8 and float16 cooperative matrix support,
which can run on older GPUs at significant performance cost (and some cost to theoretical correctness).

Note that the default "official" build of vkd3d-proton only exposes this feature when the native
VK_KHR_shader_float8 is properly supported, i.e. RDNA4+ only.
The emulation path is available when building from source with the appropriate build flags.
The decision to not include this emulation path by default is over my pay grade.
The aim is to be able to ship FSR4 in a more proper way in Proton.

No, just build a MicroATX PC if you want a fully modular system.

External GPU never make sense. When you add the size of a GPU along with a PSU to run it along side the rest of the machine, you are at the same size of a small standard PC that's fully modular.

Eh. When the PS5 released the 3090 was the best you could buy, and yeah, that was better than the PS5 GPU, as was the 3080, but the PS5 GPU is somewhere around a 2080 I believe? That was the high end card of the previous Nvidia generation at the time. The PS6 isn't releasing until like 2028, so I really doubt it will be blown away by 40 series cards from 2022. The 60 and probably also 70 series will be out by then. The PS6 will probably match the 5080 at least.
