And this is why I think Valve was very shrewd when it came to deciding what hardware to use. Not only is AMD better supported, but it feels like every update just keeps improving everything.
Doesn't matter if it's actually better on paper (I don't know if it is or isn't), because it feels like the value only improves.
they wouldnt use nvidia because outside of the driver issues, they dont have an x86 license nor nvidia does semi custom designs for clients.
valves only other option is basically Intel, which at the time, didnt have much emphasis in igpu performance to give valve a decent value/performance ratio
Isn’t the Tegra X1 on the Switch modified for Nintendo?
no, because the tegra x1 was a processor originally designed for nvidia shield tv and jetson developer boards. companies like nintendo for the switch and google for the pixel c tablet, used the tegra x1 as an off the shelf chip, which is why all of the listed devices are suscceptable to the rcm exploit, as they are the same chip.
semi custom means they are key functionality added to the chip from oem designs that fundamentally make it different. e. g valve has zen 2 + rdna 2 igpu instead of the off the shelf zen 3 + rdna 2 option. Sony for example has a memory accelerator on the PS5 to give the PS5 faster data streaming capability than standard designs. and supposedly have a compute block for the PS5 pro supposedly for better resolution scaling and ray tracing than standard amd designs.
Nvidia not doing semi custom is the main reason why Apple stopped using nvidia after the GTX 670 in their imac pro lines in favor of AMD, and for example, why nvidia is very strict on the form factor theor gpus are in (e. g theres a reason why a smaller egpu doesnt really exist much for nvidia gpus, while the AMD option is more common, despite being less bought by consumers)
Thanks for the info and examples!
