No, this is for in data center technology, not home users. This is a move diversifying away from gamers.

Agreed, it would seem like they want to get into the fabric business.

It's not that kind of Ethernet.

Intel and Nvidia dont get along so that was bad news for Nvidia. So Nvidia bought the company instead. This is a better outcome for us than Intel buying them, since this way Infiniband will still exist at least. Most likely we will see Nvidia make it proprietary though. Either outcome of this sale is still bad news for AMD.
And now the only thing up in the air is whether Nvidia maintains the Ethernet division of Mellanox or not. Right now the Infiniband and Ethernet chips are the same and can run both technologies. So it is likely Nvidia wont kill off the Ethernet side, but if they make the Infiniband stuff proprietary for them then the Ethernet chips effectively dies anyway...
Nvidia and IBM have been having a very close relationship lately, and considering IBM have also been using infiniband for their z systems and many of their new products lately, I'm not sure nvidia will really make it proprietary, but it will definitely be profitable to continue keeping mellanox alive.

Hmm. I wonder what they'll do with this tech.
I dont understand why we dont use ethernet based connections for nearly everything... we can pass all media through it, video, audio, data, with insane amounts of bandwidth... they even make more workable copper, instead of errant and angry network variants.

Heck... I just threw 4k video over cat6a a month ago from my media center to my projector, ethernet technology has made my home so convenient.

Babies are just something you have to not make die...

Ethernet simply cant do what these supercomputers need. ENet is good for general networking, but requires multiple layers and overhead. Infiniband allows direct transfers between memory of each node and has significantly reduced overhead, as well as significantly more advanced offload capabilities to save CPU cycles. Bandwidth of a 4k video? Not even remotely close to what this tech is for or has the bandwidth capability of. This is about having connections at speed of 200+gb/s on each node. Think of it more like Infinity Fabric from AMD, how it is used to connect core dies together in a coherent manner. This is similar, only allows you to connect them between chassis and even hundreds of feet apart, and still get 25 gigabytes per second between connections and higher speeds in the future. Even high end home 10gb networking is only capable of 1.25GB/s, and thats before overhead which at that 10gb speed drops you by around 120 mebaytes per second. A 4k video on the other hand can be streamed on 100mbit "fast ethernet" from 1995.

You mean like Freedom Fabric? This reminds me of AMD's move to buy Seamicro, hopefully Nvidia doesn't kill Mellanox as quickly.
