This seems to blur the lines between desktop and mobile APU’s, but I would bet that’s it’s closer to a higher clocked mobile chip, than it is to desktop. The only reason I think this is the case is due to the similarity spec wise with the Max 385, and that it’s semi-custom.

If it was just a 7600x CPU + 7600 GPU I think they would have just said so. It could be separate CPU+GPU, but I think it might be possible that it is built more like a SOC, where the GPU is just given its own dedicated VRAM.

Looking at the hardware of say a PS5, it has 16 GB of GDRR6, the same as the Steam Machine’s VRAM.

If everything is soldered anyway, there is no reason to have separate chips for CPU+GPU, especially if that hardware already exists like the AMD Ryzen AI Max line.

According to Dave2D’s review, RAM is upgradeable, and GPU has dedicated VRAM.

  Well I’m probably wrong then, framework said they couldn’t get good performance and maintain signal integrity with upgradable memory for the Ryzen Max cpus, so this is likely discrete Cpu and GPU. Probably all soldered in the same mainboard though.

    On the other hand, Framework is run by far right sympathizers and are a few billion short of what Valve’s R&D might have access too.

Cost is a factor because just as with Steam Deck the two SKUs will only differ in storage space, not in performance. Using last gen RDNA3 is 100% a cost driven choice.

There was the story recently that AMD demanded a very high minimum order (10 million or so?) for semi-custom versions of the lasest Ryzen and RDNA iterations for some Xbox handheld which is unlikely that handheld would sell.

By going this route, Valve avoided this. Surely there is spare manufacturing capacity for RDNA3 by now.
