How do you build devices capable of producing or consuming data at that rate? I looked up the data transfer rates of RAM[0], and this is twice as fast as the fastest species of dual-channel DDR5.

- senttoschool 3y agoI think the applications would have to be in data centers where environments are controlled and certain hardware can easily eclipse 224GB/s such as GPU memory. But I'd assume that if you're in a datacenter, you can use physical wires since you control everything.
- jbotz 3y agoEven if your devices can't produce or consume data nearly that fast, it's still good to have all that bandwidth at the link level because you'll probably be sharing it with multiple devices.
- lostlogin 3y agoDoesn’t that leave the same problem - the thing linked with multiple devices can’t take that data rate? Or are you saying that A > B might use half that data rate while X > Y uses the other half?
- jakewins 3y agoMaybe this would be in some sort of specialised network appliance, bridging the link into a wired network of some kind, not a general-purpose machine buffering the network data in regular RAM?
- justinclift 3y agoFrom rough memory, network switches often have total switch bandwidth figures measured in terabits per second. So "where several other devices intersect" seems like reasonable first thought for where large speeds are needed.
- ooterness 3y agoModern GPUs routinely exceed 5 Tbps in memory bandwidth. (GDDR6X at 20 Gbps per pin, times 256-bit bus width is 5120 Gbps.) The original article unfortunately quotes incorrect units: 224 Gbps (gigabits per second) is NOT the same as 224 GBps (gigabytes per second).
