This is cheap compared to GB200, which has a street price of >$70k for just the chip alone if you can even get one. Also GB200 technically has only 192GB per GPU and access to more than that happens over NVLink/RDMA, whereas here it’s just one big flat pool of unified memory without any tiered access topology.
We finally encountered the situation where an Apple computer is cheaper than its competition ;-)
All joking aside, I don't think Apples are that expensive compared to similar high-end gear. I don't think there is any other compact desktop computer with half a terabyte of RAM accessible to the GPU.
I mean expensive relative to who, Nvidia? Both are enjoying little to no competition in their respective niche and are using that monopoly power to extract massive margins. I have no doubt it could be much cheaper if there was actual competition in the market.
Fortunately it seems like AMD is finally catching on and working towards producing a viable competitor to the M series chips.
