5090: 32GB RAM (newegg & amazon lowest price seems to be +300 more)

4090: 24GB RAM

Thor & Spark: 128GB RAM (probably at least 96GB usable by the GPU if they behave similar to the AMD Strix Halo APU)

Earlier quoted context omitted.

This thing has a ConnectX-7, which gives it 2 x 200 Gbps networking. The 10 gig port is far from the fastest network interface on the Spark.

But can you hook that up to a normal PC?

You were complaining about speed. Yes, a PC can have the same ports, and then you get much faster speeds than Thunderbolt can provide.

Why would you ever want a DGX Spark to talk to a “normal PC” at 40+ Gbps speeds anyways? The normal PC has nothing that interesting to share with it.

But, yes, the DGX Spark does have four USB4 ports which support 40Gbps each, the same as Thunderbolt 4. I still don’t see any use case for connecting one of those to a normal PC.

Once the updated Mac Studio with M4/M5 Ultra comes out, pretty much going to make the DGX irrelevant right?

Ultras are pretty expensive.

I mean the spark is $3,999 and current M3 Max 28-Core CPU 60-Core GPU is the same price. I would expect the refreshed studio will stay around the same price.

where does an RTX Pro 6000 Blackwell fall in this? I feel like that’s the next step up in performance (and about the same price as two Sparks)

I thought the 6000 was slightly lower throughput than 5090, but obviously has a shitload more RAM.

I like the cut of your jib and your experience matches mine, but without real numbers this is all just piss in the wind (as far as online discussions go).

You're right, it's unfortunate I didn't keep the benchmarks around: I benchmark a lot of configurations and providers for my site and have a script I typically run that produces graphs for various batch sizes (https://ibb.co/0RZ78hMc)

The performance with offloading was just so bad I didn't even bother proceeding to the benchmark (without offloading you get typical H100 speeds)

Dunno, doesn't seem that good to me. Granted, I recognize the pace of advancement, but fwiw at present time.. yeah.

I'd rather just get an M3 Ultra. Have an M2 Ultra on the desk, and an M3 Ultra sitting on the desk waiting to be opened. Might need to sell it and shell out the cash for the max ram option. Pricey, but seems worthwhile.

Power consumption : TBD ?? this seems more than a little disingenuous...

from https://www.servethehome.com/this-is-the-asus-ascent-gx10-a-...

  ASUS and NVIDIA told us that their GB10 platforms are expected to use up to 170W.
[edit] the PSU is 240W so that'd place an upper limit on power draw, unless they upgrade it.
