quote: Because modern DRAM modules' CAS latencies are specified in clock ticks instead of time, when comparing latencies at different clock speeds, latencies must be translated into actual times to make a fair comparison; a higher numerical CAS latency may still be a shorter real-time latency if the clock is faster
quote: Latency can cause the CPU to hang (especially for sequential/non threaded instruction sequences), and will slow down execution.
quote: latency measured from the balls of the package?
quote: Reduced Latency – Enables significantly lower system latency as a result of HMC’s massive parallelismReduced Latency – With vastly more responders built into HMC, we expect lower queue delays and higher bank availability, which will provide a substantial system latency reduction.
