Latency vs bandwidth

So I have gone balls to the wall with my old 7600k (@4.7 GHz) and purchased a 4000 MHz Samsung b-die memory kit. Obviously I forgot to check if my ageing motherboard managed that frequency (it did not). The positive aspect is that I managed to run it at very aggressive timings @ 3466 MHz
@3333 MHz (13-13-13-33) my system managed to run the benchmark at 265 seconds. @3466 MHz (14-14-14-34) it finished at 264 seconds. (both a rather sizable difference compared to the 2400 MHz (15-15-15-36) memory I hade before when it finished at 321 seconds) My question is what we should try to go for in terms of CFD? Is bandwidth the king or do we have enough random reads that latency is important as well? I am a bit confused right now by the results. |
