i always thought Ryzen AI Halo, together with DGS Spark, has mismatched compute capacity with memory size. Given 128GB VRAM, people would want to run large models, but the GPU compute is constraint in these types of use case. If the box runs models that don't need high compute, then there is no need of 128GB VRAM.
On the high end side, it is too slow. On the low end size, it waste money on VRAM.
