Is this just dgx spark, but a laptop?

View on HN

yes, same chip

+ Windows

+ Screen

- ConnectX-7 Smart NIC

What about the desktop version? It seemed like it is not a dgx since it has the CPUs cores done by mediatek

desktop is GB300, not GB10 like Spark

they also announced a GB10/N1X windows desktop mini PC.

GB300 is nominally "available" in desktop form factor workstations priced around $100k. That's a few orders of magnitude away from the ordinary desktop PC market that consumers participate in.

Yeah this is why it’s important to get something with similar programmability for less money. I don’t need the power of a gb300 just to do experiments with tma or “tcgen05” instructions

They didn't say that Mediatek made the cpu sores. Grace is NVidia's own cpu arm cores. I bet that Mediatek made other parts of SoC necessary for a notebook

NVIDIA hasn't done custom CPU cores for anything they've yet branded "Grace". The original Grace data center CPU (paired with the Hopper data center GPU) used ARM Neoverse V2 cores. The "GB10" chip shipped in DGX Spark and announced here for RTX Spark uses Cortex X925 and Cortex A725 CPU cores.

Physically, NVIDIA did the GPU chiplet and Mediatek did the other chiplet that has the CPU, DRAM controller, and IO.

MediaTek said MediaTek made the CPU: https://www.mediatek.com/press-room/mediatek-collaborates-wi...

Well, MediaTek actually said they made most of the SoC in fact. But the actual CPU cores themselves are all but certainly off-the-shelf Cortex parts, since MediaTek doesn't have a custom core design at all afaik.

The DGX Spark/GB10 has CPU cores from Mediatek (in a pretty odd cluster configuration, too).

+ battery too. I've wondered if a mini pc with battery would make for a good form factor. I often move between places where I have a desk with a screen but still use a laptop because I want to just suspend and resume. If a mini pc had a small battery just to hold its RAM while suspended I could move between places and just plug in a single USB-C cable and have my full workstation up and running. The thermals could be better than in a laptop and having a built-in UPS better than with a desktop. But last time I checked no one packaged things like that.

There's the Khadas Mind series of mini pcs. They have a proprietary docking interface though. Agree that it would be great if this form-factor was more common.

Can the link type be toggled between Ethernet and Infiniband? (Don't think I've ever heard of a laptop with IB.)
