It is the same CPU previously used in the overpriced DGX Spark.

It has 10 big Cortex-X925 cores, which are competitive with the Intel P-cores and with the AMD Zen cores, plus 10 small Cortex-A725 cores, which are similar in performance with the older Intel E-cores, from the Meteor Lake, Raptor Lake and Alder Lake generations. The current Intel E-cores are similar to Cortex-X4, i.e. they are much faster.

This Arm based CPU is more powerful that any Arm-based CPU previously used in a non-Apple PC, but in multi-threaded applications it is inferior to AMD Strix Halo CPUs.

The GPU of this is different from that of DGX, which was good only at ML/AI, but poor for graphics.

Here the GPU is likely to be good for graphics, and the top model will have up to 6144 FP32 execution units compared to 2560 of Strix Halo. But I assume that at least the top models will also be much more expensive than Strix Halo.

This NVIDIA CPU+GPU is limited to 128 GB of DRAM, while the successor of Strix Halo, which has been announced recently, offers up to 192 GB of DRAM, so NVIDIA continues its tradition of always providing less memory than its competitors, in order to have better profit margins.
