alt Hacker News> We need a more expensive CPU, more expensive motherboard, more power, more cooling, and a larger system. Congratulations you've reinvented threadripper (4 channel), siena (6 channel), Threadripper pro (8 channel), or epyc (12 channel).
This is the real story not the conspiracy-tinged market segmentation one. Which is silly because at levels where high-end consumer/enthusiast Ryzen (say, 9950 X3D) and lowest-end Threadripper/EPYC (most likely a previous-gen chip) just happen to truly overlap in performance, the former will generally cost you more!
Well sort of. Apple makes a competitive mac mini and macbook air with a 128 bit memory interface, decent design, solid build, nice materials, etc starting at $1k. PC laptops can match nearly any aspect, but rarely match the quality of the build, keyboard, trackpad, display, aluminum chassis, etc.
However Apple will let you upgrade to the pro (double the bandwidth), max (4x the bandwidth), and ultra (8x the bandwidth). The m4 max is still efficient, gives decent battery life in a thin light laptop. Even the ultra is pretty quiet/cool even in a tiny mac studio MUCH smaller than any thread ripper pro build I've seen.
Does mystify me that x86 has a hard time matching even a mac mini pro on bandwidth, let alone the models with 2x or 4x the memory bandwidth.
