The ConnectX 7 2x200 Gbps networking card in the DGX Spark alone is worth $700
- KeplerBoy 5mo agoTo be fair the connectx-7 in the spark can't even push 2x200 Gbps since it is connected via 4 pcie lanes.
- Ballas 5mo agoTechnically it's connected via 8 PCIe gen 5 lanes (two 4x connections), allowing ~100Gbps per port.
- KeplerBoy 5mo agoThanks for the correction. I should have looked it up; I only remembered it being somewhat odd.
- fmajid 5mo agoYes, ConnectX-7 itself is capable of 32x PCIe5 lanes, but the lane limitations of the GB10 SoC/chipset throttle it: https://www.nvidia.com/content/dam/en-zz/Solutions/networking/ethernet-adapters/connectx-7-datasheet-Final.pdf https://www.nvidia.com/content/dam/en-zz/Solutions/networkin....
