Title "HASWELL-E 8Core/16T How much faster will it be, because of DDR4 rather than DDR3 ?", says it all.
Any discussion about Haswell-E and/or DDR4 is fine, in this thread.
But the poll is for DDR4's speed improvement, over what it would have been if DDR3, SPECIFICALLY/EXCLUSIVELY for the HASWELL-E 8 Core/16T Enthusiasts Intel cpu
Definition for poll: Speed up based on running a mixture of Benchmarks (all inc games) and real life software usage (compared with if Haswell-E 8C had used DDR3)
I.e. How much faster is a "Haswell-E 8C DDR4", over a (non existent, as will never support DDR3) "Haswell-E 8C DDR3"
E.g. if it was a 10% speed up, and the identical (Haswell-E 8C) took exactly 100.00 Sec, with DDR3
Then DDR4 would take about 91.00 Sec
------------------------------------------------------
DDR4 seems to offer point to point topology.
Advantages
Possibly faster
Lower voltage, so may reduce power consumption
More future safe
Point to point, probably improves things
I think only one slot needs to be filled, no longer need to do it in pairs, but filling all slots, is probably best
Disadvantages
Predicted to be expensive compared to DDR3, in the early stages of DDR4 availability
On a Socket2011++ board, only 4 sockets, rather than 8
Half number of sockets, so need twice capacity Rams, in order to achieve the same (total motherboard) capacity, which tends to be disproportionately more expensive. (e.g. 8 slot x 4 Gb ($20) = $160 for 32 Gb tot, but 4 slot x 8 Gb ($60) = $240 for 32 Gb tot)
May be difficult to get hold of, when Haswell-E first becomes available
Note to mods: I felt it best to put this in the cpu section, as it's about Haswell-E's possible speed benefit because it now uses DDR4. But, if you think this is best in memory, because of DDR4, then please move this thread.
