Pardon me if this has been discussed and answered already, but I am still struggling to find info around it, and perhaps we simply just do not know yet. DGX Spark vs RTX Spark. What is really the differences here? Why are there 2 different products for seemingly the exact same thing? Am I missing …

It’s the same GB10: https://www.youtube.com/watch?v=wbg5KlH_T18

The RTX will be power limited so will not be able to run at the same speed as the DGX Spark. RTX Spark will also be available in cut down/cheaper versions with less cores/RAM.

DGX = enterprise while RTX = consumer, thus no CX-7 on the RTX Spark.

The big question for me, since both DGX and RTX are GB10 chips, will they use the same LPDDR5X chips as well? If so, it would seem like 300GB/s is only a matter of a firmware update for DGX owners.

To be honest, they looks like very similar in terms of CPU/GPU architecture, and to me what is really interesting it’s to understand if we can get the same software stack to run on our DGX Spark. DGX Spark with linux is great to host and act like an home server, while RTX Spark with windows looks li…

The more I think about it, the more I think the 300GB/s number is just Nvidia and partners rounding up. It is not unheard of for specs to be discussed or disclosed that way. It is very likely the exact same platform with lower memory options and no CX-7 ports. Which should in theory bring the price…

I thought long and hard about it, not in a search of new pc, but potentially I want a great working laptop for work and travel. I have a pretty good one, 2 yo i9 with 32g and rtx 4070ti 12g. Ideally I want a rocketship of course. But rtx spark just seems is nowhere. Underdeveloped windows arm, not n…

I was thinking the exact same thing. Windows on ARM is the biggest liability here. However, the fact that Microsoft has partnered with NVIDIA on this leads me to believe that they want to make Windows on ARM drivers more mature for NVIDIA products. I just can’t see the upside otherwise.

The more I think about it, the more I think the 300GB/s number is just Nvidia and partners rounding up. Could be, or they could be using faster memory. Our DGX Spark units use LPDDR5X-8533: Size: 128 GB Configured Memory Speed: 8533 MT/s <...> This article from The Verg…

RTX drops the ConnectX-7 interface, so it will probably be cheaper, but it loses the fast connection between nodes. It will have marginally better memory bandwidth (300gb/s vs 273 for DGX). Feels like it’s for people who want a mini pc to play around with smaller models and maybe do some gaming.
