The Mac Studio M3 Ultra with 96GB of RAM with 1Tb SSD costs $6799, but has triple the memory bandwidth [1]. It's almost twice the price of Strix Halo and when the M5 Ultras come out it will be interesting to see how much they go for. I expect a lot of demand for them!

There was a post recently, that showed the DGX spark is twice as fast as the M3 Ultra at prompt processing, but half as fast at output tokens [2]. They used gps-oss-120 for that test with a small context.

I’ve got a 128gb m5 max mbp and two sparks. For my real-world use cases, a single spark running DS4 Flash will have fully responded by the time my Mac has even started generating tokens. I figured I’d have more generation heavy work when I also bought the Mac, but it has done very little work running LLMs since I got the first Spark.

I mostly run them clustered for DS4 and am quite happy with the performance, and the cost isn’t that much more for two than the MBP while giving me double the unified memory.

I’ll probably pick up a third to run multiple smaller models. I don’t understand why people would buy a halo over a spark at comparable prices, particularly because if you want to cluster, the cx7 be beats the shit out of them when it comes to latency and throughput
