When will DDR4 come out?

[Ralms]

Hi there guys,

 

Just out of curiosity I was wondering if anyone has any info on this topic?

I know that the new Intel chips use DDR3 but DDR3 is on the market for so long I wonder when are they stepping up to DDR4?

 

Another question, do you guys think it will be worth it? Will we feel any massive difference? 

 

From what Ive seen in the link below from crucial is that the memory density is way higher and that is a good thing. If I can have 48GB of memory in my system for a good price I want it xD

 

Thanks.

For Intel my guess would be either Skylake or Broadwell. Broadwell supersedes Haswell but still uses the 1150 socket or so I've been lead to believe. Currently there's no real need to go for DDR4 RAM as the performance isn't needed.

According to wikipedia, it is rumored that mainstream DDR4 support will be delivered along the Skylake microarchitecture, wish is rumored to start commercialization around 2015. From the AMD side I don't really know, but probably sooner.

There is no real difference between dualchannel and quadchannel, essentially the double bandwidth. So i guess it is save to say that DDR4 will make no real performance difference.

Even within DDR3, increasing the RAM speed doesn't make much difference to overall system performance, so I doubt that going to DDR4 will do that much either. This is simply because the software ends up running within the on-chip cache rather than main RAM, and the on-chip caches keep getting bigger. Mostly, the main RAM speed just affects how fast the software is transferred from main RAM to the cache(s).

 

So, DDR4 will come into use at some point (perhaps - if it's not skipped for something even faster), but it's not something to be excited about. :)

Broadwell will usea BGA (Ball Grid Array) rather than LGA

I think AMD are gonna push it before intel makes a move. this will force intel to follow AMD

There's no need for DDR4, well only for APUs, but most systems don't need it.

amd would push ddr 4 the most for there apu. though i think by next year they are gonna try gddr5 soldered on motherboards with there steamroller apus

I was reading some stuff. Looks like that Intel is gonna release his new 2011 socket processors in the 3Q of 2013 with support for DDR4. Basically the new high end processors will most likely have support for it.

 

The biggest advantage on the new Ram will most likely be the $ per GB since they have 2x the density. Which will be good allowing us to have some Ram cache and stuff. So you stress less your SSDs, etc for more performance.

I doubt Ivy Bridge E will have a new memory controller with DDR4 support.  They're making it for socket 2011 and switching to DDR4 would defeat the purpose of sticking with the same socket so people could upgrade down the road.  Ivy Bridge uses DDR3, and Haswell uses DDR3, I see no reason why Ivy Bridge E would use DDR4.  It's much too early for that.

amd developed GDDR5 so...this should be easy for them.

That is not true. Who developed the first DDR4 was Samsung and not AMD

"Intel is reportedly developing an ultra high-end processor that they've codenamed "Haswell-E."  It will replace the Ivy Bridge-E, a CPU that hasn't even been released yet but [ivy Bridge-E] is expected to arrive in Q3 2013."

 

 

Haswell-E may support DDR4.  Ivy Bridge-E is what they're expecting to arrive in Q3 not Haswell-E, and Ivy-E will use DDR3.

ATi did most of the initial development and Samsung and Infineon jumped on afterward to help.  ATi is mostly credited with the development of it though, as they were with GDDR3 and GDDR4.

APUs should and will use separate soldered GDDR5 memory for better performance.Integrated DDR4 It will still bottleneck those chips. So i was not reffering to DDR4.

DDR 4 should come late 2014 - early 2015, Haswell-e should be the 1st chip able to support it, and the rumored x99 chipset. There is an indication Broadwell, but i doubt they will let "lower" level LGA get premium features sooner, maybe i am wrong

That would increase the cost of the APU platform which sort of defeats the purpose; it needs to cater toward people who can't afford a graphics card at all.

The only problem I'm going to have with DDR4, and it's one of the major downsides, is the increased latency that it will have.
