I assume the ES on the end means engineering sample? I suppose they could be any speed...?!

Nice! I grabbed two just now. Looks like an MCX414A-BCAT like from the stock photo they used. We'll see what gets here =)

Other than port types/configs, what is the difference between the ConnectX-4 EN line and the ConnectX-4 Lx EN? I might be blind but I'm not seeing much of a difference in the product briefs...

I got mine today, they are the MCX414A-BCAT dual ports with 40/56GbE QSFP28. Great find!

They came in the boxes for MCX456A-ECAT cards, for a few seconds I had dreams of going straight to 100 GbE but it wasn't meant to be ;)

Mine just came too. I was SO excited like OMG I'm getting 100g cards. Not to be.

Consolation, extra port per card and I got a spare LP bracket in one of the boxes.
