@civiloid can tell for sure.
Network Cards are Mellanox Cx6
Earlier we played with a W790E-SAGE SE, and CPU that was used was Xeon-W5 3435X (16 core/32 threads sapphire rapids-ws-112).

But he used a different CPU for this last test (because T-Rex was taking 84 cores total).

@benjojo @IPngNetworks that is 2x Xeon 8490H ES (I'm not rich enough to buy production silicon of that price), but I can get 1 Gpps even if I limit it to 7 cores per dual port, so you probably can get away with 2x Xeon Gold 6430 or 6530 (better to go for EMR if possible).

16x16 DDR5-4800 RAM

As about NICs - 4x ConnectX-6 DX , 1x ConnectX-5 DX, 1x BlueField-2.

I have patched Cisco trex, but at this moment, it is mostly QoL kind of patches (e.x. one to display all cards in a single TUI).
