  • 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)











  • i mean historically, this isnt new. CPUs and GPUs will always introduce some new compute unit thats highly specific workloads using up die space. take cpu examples like AVX2, AVX512 for example, or Aegia Physx hardware, or Nvidias Tensor units to allow for tech like raytracing/upscaling or all hardwares video decoder/encoders.

    Companies will push the changes on their hardware regardless, and they will only remove it if it interferes with a core design of a chip (e.g Intel P/E cores disable AVX512 because E cores do not have AVX512 units) or gets i a point that barely anyone uses it.

    if you never want to buy into thia kind of tech, then choose to never buy whoever is the most popular cpu/gpu in a market, because people at the top invent new things to further the gap between them and everyone else, as they are usually first and foremost, publically traded companies.
