where do you see "twice the memory bandwidth"?

The M4 Max with 128GB RAM has 546GB/s memory bandwidth [0], compared to Strix Halo's 250 (on the label, I've yet to see a benchmark that tops 220). It's not available at 128GB RAM anymore, at least in my shop, but when it was not so long ago it was about 4,7k, or a little over twice the price of a cheaper Strix Halo PC (around 2,2k a few months ago).

He is making things up. It is the same bandwidth as DGX Spark (256 GB/s vs 273 GB/s) and far behind M3 Ultra (~819 GB/s)

You're the one making things up. An M3 Ultra with 128GB RAM doesn't exist, the M3 Max has 410GB/s bandwidth [0]. I was of course talking about the M4 Max with 546GB/s, which was closer to twice the price of a Strix Halo mini PC in a typical configuration when it was still available. And memory bandwidth isn't everything, NVidia's lead in software is substantial, look up any tests comparing them side-by-side.

They have 96, 128, 256, and 512GB variants my friend.

They stopped selling anything greater than the 96 gig variant a while back. If you want more RAM, be prepared to bid high on ebay.

Well, some exist, but I guess they don't make any new ones for now.
