Comment Re:Latency probably sucks (Score 2) 20
It's been my general impression that physical latency (as measured in ns) is roughly constant across all DDR generations. But it's interesting to note that the best latencies are seen around DDR3. The latest generations seem to want throughput at the expense of latency.
"Why people think "performace" means "throughput" is something I'll never understand. Throughput is _always_ secondary to latency, and really only becomes interesting when it becomes a latency number (ie "I need higher throughput in order to process these jobs in 4 hours instead of 8" - notice how the real issue was again about _latency_).
