Any thoughts guys? I know the standard is starting to make the rounds to the manufacturers and Haswell is said to support it.

Hynix started making DDR4 modules last year to send to their "customers". AFAIK, they were the first to start manufacturing it. Very likely that Haswell systems will come with it, but time will tell for certain.

If Haswell systems do come with DDR4, then I suspect that will account for most of the performance gains in those systems over current gen CPU's. Of course, lots of people will attribute the performance gain to the CPU, so I expect there to be a fair bit of confusion in the "blogosphere" or forums in that regard.

haswell dont support it, we know broadwell does. Haswell E supports that.

The idea is 2014, and given the leaked tid bit about sata express in chipset 9 (broadwell chipset) Im glad Im going to buy a notebook only next year or the other
 
Not haswell, but probably broadwell. The rmbp already uses DDR3L, so that's pretty fancy already :)
 
Not really. DDR3L has been around for like 2 years and could work on most systems just like that if they allowed the different settings. So basically any desktop and some notebooks.
It also only saves a very small bit of energy. Like 1-2W under load and 0.4W idle. Also no performance difference whatsoever. Not fancy.

DDR4 will be pretty neat for integrated GPUs. Honestly I think with the whole IGP push this year and last they should be ready for DDR4 now and no wait so long. CPUs don't need it but those IGP sure do and it was ready for a while. DRAM manufacturers have mostly been waiting for the go ahead of the CPU/GPU guys.
End of 2014 will be DDR4 arrival.

couple that with the new kaveri design with GDDR5 and the new broadwell igpu arch, with DDR4 we might see a good improvement there

and that 1-2w and 0.4w figures are actually around 20min+ of battery, still the thing that draws more energy is the screen, but anything is welcome
 
You both are right, DDR4 will be supported in Haswell.
At the moment it is confirmed to be in server versions:

Confirmed new features of Haswell

* Haswell New Instructions (HNI includes AVX2, FMA3, gather, bit manipulation)
* New sockets — LGA 1150 for desktops and rPGA947 & BGA1364 for the mobile market
* Intel Transactional Synchronization Extensions (TSX)
* Graphics support in hardware for Direct3D 11.1 and OpenGL 4.0
* DDR4 for the enterprise/server variant (Haswell-EX)
* Variable Base clock (BClk) like LGA 2011
* Supervisor mode access prevention (SMAP)

DDR4 could come to consumer Haswells as well, but not at the same time with server.
Or it could not come at all, and we will have to wait until Broadwell. Who knows :rolleyes:

I doubt we'll see it in the next MacBook Pro release - the features listed on the wikipedia sounds like the high end workstations and servers have the most to benefit from it hence if anything the Mac Pro users should be getting excited before us MacBook Pro users.

What is a Mac Pro? :rolleyes:
 
DDR4 seems to be delayed because of the weak PC market.

If we are lucky we'll see it on the client next year, but that's just what I hope for.
 
So I don't have to worry about my new 2012 iMac being outdated in a few months when the new CPUs are likely to surface :rolleyes:
 
Just search the news.

i have searched and came out with the confirmation that haswell EX will come with DDR4, we still dont have hard intel evidence aside long leaked things on broadwell

so source?

I dont see economical or other technical reasons for this

I said client, not server.

kk, i still dont see the reason.

the leaked info is from 1 year ago, while its not as solid, intel leaks are usually accurate

and given the ramp up on production for the DDR4 by the 4 manufacturers, and given that broadwell is basically a SoC most of the times, it quite a huge ordeal to change all to DDR3
 
The news says DDR4 is now not expected to be in volume production until 2015/2016 because of lack of demand.

again please show me that, I havent saw it, crucial and samsung are moving forward with the 2014 plan, the others I have no clue, they are more tight lipped

one thing that I forgot, there are only 3 now, crucial bought elpida, so it remains, crucial, hynix that has an apparent partnership with samsung (which doesnt make much sense), and samsung. So we are only missing hynix here
