Does 2400Mhz DDR4 has better performance than DDR3 at 2400mhz?
I guess it has better performance, But how much does the DDR4 performance will be higher than the DDR3 at the same speed?
Thank you.

CAS latency is a factor too.

But normally they would perform the same, the DDR4 will use less power to do it though.

DDR3 and DDR4 are almost exactly the same aside from the lower voltage and DDR4 having twice as many internal banks per chip. The problem is DDR4 has higher latency (2400-15-15-15 for DDR4 vs 2400-11-11-11 for DDR3) and that will make it slower than an otherwise same-speed DDR3 DIMM.

Price is also an issue with DDR4 costing over 50% more than DDR3.

The only PCs on the market that can use DDR4 right now are LGA2011-3 CPUs on x99-based boards so there is no point in worrying about DDR4 unless you want to build around an i7-5820k/5930k/5960X. If you do, there is no point in thinking about DDR3 since LGA2011-3 only works with DDR4.

Started what? Being a mod? About a month ago. The avatar? Maybe a week ago. The "other thing?" After I read about de Lancie's unexpected fan-mail, many months after-the-fact.

Long enough. I remember making a few inside jokes when commenting on your comments over a year ago.

That's enough off-topicness. Any more of this and I may have to start snapping my fingers to make comments poof out of existence unless one of the other mods beat me to it. We can continue in private or elsewhere.
