As the number of cores per socket is steadily increasing it is becoming more difficult to keep all of the cores on a single computer operating efficiently. A higher clock rate per core, or more cores per socket, is not very useful if they are all waiting on memory.
- rbanffy 15y agoUnless we are considering coupling lots of memory to the cores themselves, bypassing slow external buses.
- pjscott 15y agoNow imagine a large amount of memory connected to the cores through tiny metal wires on the chip itself. Now imagine that it's split into a bunch of small independent memories with enormous bandwidth, with data automatically migrating between them to cut down on wire delays. Give it a few years, and this could be reality.
