DGX Spark is a fantastic option at this price point. You get 128GB VRAM which is extremely difficult to get at this price point. Also it’s a fairly fast GPU. And stupidly fast networking - 200gbps or 400gbps mellanox if you find coin for another one.
Internet seems to think the SW support for those is bad, and that strix halo boxes are better ROI.
Can even network 4 of these together, using a pretty cheap InfiniBand switch. There is a YouTube video of a guy building and benchmarking such setup.
For 5K one can get a desktop PC with RTX 5090, that has 3x more compute, but 4x less VRAM - so depending on the workload may be a better option.
I’m not very well versed in this domain, but I think it’s not going to be “VRAM” (GDDR) memory, but rather “unified memory”, which is essentially RAM (some flavour of DDR5 I assume). These two types of memory has vastly different bandwidth.
I’m pretty curious to see any benchmarks on inference on VRAM vs UM.
