The specifications are at:

https://www.nvidia.com/en-us/products/workstations/dgx-spark...

DGX Spark has the same memory as AMD Strix Halo, a weaker CPU, but perhaps a stronger GPU, except that for now there is no data about the GPU, besides that it might be stronger for AI inference (only FP4 speed is given). For now it is not known whether for graphics it will be better than Strix Halo.

While DGX Spark might be weaker than AMD Strix Halo for anything else except AI Inference, it will still be stronger than any mini-PC made with Intel Arrow Lake H or with AMD Strix Point.

CPU specs from the nVidia page above:

20 core Arm, 10 Cortex-X925 + 10 Cortex-A725 Arm

Anandtech's 2024 article about the X925 & A725 Arm cpu cores:

For operations with floating-point numbers, big integer numbers or arrays, a Cortex-X925 matches 3/4 Zen 5 full cores at the same clock frequency, while Cortex-A725 matches 1/4 Zen 5 full cores.

So DGX Spark is equivalent with at most 10 * 3/4 + 10 * 1/4 = 10 Zen 5 cores versus 16 Zen 5 cores of Strix Halo.

In reality DGX Spark will be even slower, because it will have a lower clock frequency (especially the Cortex-A725 cores) and a worse cache memory.

For irregular code that does only operations with pointers and integers, the advantage of AMD Strix Halo will be significantly less, but even in that case the 10+10 cores of DGX Spark are unlikely to match more than 15 Zen 5 cores at the same clock frequency and less than that at the real clock frequencies.

On the other hand, like I have said, DGX Spark should be faster than Intel Arrow Lake H, the best that Intel can offer in a mini-PC of this size.

I'm somewhat surprised they are not explicitly mentioning the networking capabilities. There should be two QSFP(?) ports but they don't mention if their speeds and supported protocols (possibly not just Ethernet but also infiniband, but probably not).

Could be 2x200 Gbit/s, could also be much less.

It will be better than strix halo. Even the Orin AGX GPU is better than strix halo and that is Ampere.

Perhaps you are confusing Strix Halo with Strix Point.

The GPU of Strix Halo is many times faster than the GPU of the biggest Orin AGX.

The Strix Halo has 25% more "CUDA cores" (2560 vs. 2048), which work at a clock frequency that is more than double (2.9 GHz vs. 1.3 GHz) and which can have for some operations a double throughput even at the same clock frequency. The memory throughput is also higher by 25%.

The GPU of DGX Spark will have to be 4 or 5 times faster than Orin to match Strix Halo as a GPU. This is not at all certain because NVIDIA has stressed only AI/ML applications without saying anything about graphics.

You're right, my bad.
