AMD's cores have SMT, allowing them to run two threads at a time and appear to the OS and its scheduler as two logical cores despite being implemented as a single physical core.

DGX Spark vs. Strix Halo vs. M4 Max is hotly debated. You can find plenty of HN discussions and YouTube videos about it.

In Europe these cost 5k EUR. I guess I'm not buying computer ever again and hopefully the 10 years old ones I have will never die.

Most likely, it's just a matter of time and the NVIDIA DGX Spark is partly serving as a pipe cleaner product. They clearly need to work on power management, and solid Windows support may be more work than the Linux support they've shipped so far.

Mediatek-based laptops (other than the existing Chromebooks using what's more or less Mediatek phone chips) are one of the big things to keep an eye out for at CES next week. They have a solid market opportunity to provide an alternative ARM solution to compete against Qualcomm's Snapdragon X Elite and upcoming X2 Elite: having a NVIDIA GPU would give Mediatek a huge advantage over one of Qualcomm's most pronounced weaknesses, and the CPU cores Mediatek is using are probably "good enough" for a GPU-focused system (mobile AI workstation or low-power gaming laptop).
