nitrium :
I still would like to see what this means in real world situation.
Exactly. I commented similarly in the last DDR4 review. I have a feeling DDR3 would be pretty much just as good for Skylake, but we'll see. RAM is still expensive - I have 16GB of DDR3 1866 but am running it on an antique i5 760. If I upgrade to Skylake I would like to know if I should just get a DDR3 1151 mobo and keep my RAM or go for a DDR4 one with all new RAM. Apparently an article on just this is coming next week.
Already published last week

Basically, if you want to upgrade your memory capacity, you should consider replacing it with DDR4. If you think you'll be happy with your capacity for a long time, it's OK to stick with DDR3.
that was a terrible article where low power green energy ddr3 was pitted against ddr2 on steroids ddr4 which can't even adequately challenge ddr3 3000+
it's like the conversion from ddr to ddr2 when ddr ended at 400mhz and ddr2 picked up with 266mhz.
ddr4 is the equivelent of ddr2 with even lower power on a new die shrink allowing higher clocks. it's not even a real upgrade, especially starting out at speeds 800 mhz under ddr3's highest rated speeds which was 3200...seriously ddr4 2133? stop recycling old ram spec on new die shrinks if you can't make the new starting speed atleast faster than ram that's over 8 years old
this article further reinforces it with only a 100mhz gain over crucial ballistix tactical with tracer leds even at 1.5v running stock 1600mhz at 8-8-8-24. and this ram is 4 years old. what's ddr4's excuse? NONE over priced slower recycled spec of previous generation 2 ddr on a new die shrink. wait for ddr4 to get to the 4,000mhz mark or wind up in the same boat you were with ddr2
WE ARE ON TO YOUR GAME RAM MANUFACTURERS.
this ddr4 374cycles row refill rate is horrendous, you can load the ram up, but emptying and reloading eats so many cycles it allows ddr3 1333 refresh's to blow right past it at almost 3 times per charge.
the sad thing is crucial ballistixs tactical tracer ddr2 1066mhz running 5-5-5-15 with a row refresh of 32 to 24 can still score on the board against ddr4, yes that ddr2 will be slower, but on a pentium or i3 you are barely going to notice the difference.
i'm sure if you die shrank ddr2 to 14nm and die shrank core2quad you could crank out 4k mhz clock rates all across the board at 12-12-12-32 at row refresh of 128-140
and stomp sky lake arse into the mud with a 30% increase in round the board/table performance especially with the new encryption standards implemented.
learn from the ddr2 lesson upgrade your ddr3 right now to the fastest possible ram and get another 5 years out of your current system easy and wait for intel generation 2020 ddr5 with a year to spare for that generation prices to go down
