>But what about latency?
From a high level overview DRAM latency has been the same and will stay the same for long time. Doubling the bandwidth, lower energy usage, double capacity all while staying with the same latency is about as good as it get for DRAM. You will need eDRAM to get lower latency. That is why we see the trend of an increase of cache size on CPU.
