DDR4 Memory Prototypes Demostrated at ISSCC
Two DDR4 memory modules were shown off at this years ISSCC.
With DDR4 DRAM set to hit the market in 2013, two manufactures took the opportunity at this years International Solid-State Circuits Conference (ISSCC) to demonstrate their DDR4 DRAM. It is expected that DDR4 will represent 50 percent of the market by mid-2015, after its initial launch on the server side in 2013.
DDR4 is set to have a data transfer rates of 2133 MT/s to 4266 MT/s compared to 800 MT/s to 2133 MT/s of DDR3. DDR4 is also expected to have significantly lower voltage requirements than DDR3. It will require between 1.05 V to 1.2 V to operate, whereas DDR3 requires between 1.2 V to 1.5 V. The lower voltage requirement is expected to reduces power consumption by 40 percent compared to a 1.5 V DDR3 module. DDR4 will not be pin compatible with DDR3, which means they will not be backwards compatible.
Samsung's DDR4 DRAM module can achieve data transfer rates of 2133 Gb/s at 1.2V, compared to 1.35V and 1.5V DDR3 DRAM at an equivalent 30nm-class process technology, with speeds of up to 1.6 Gb/s. Hynix's DDR4 device works at 2400MHz (2400 Mb/s) at 1.2V and processes up to 19.2 GB/s of data per second with a 64-bit I/O. Hynix used its 38nm manufacturing process technology, while Samsung employed the 30nm node instead.
Other manufacturers such as, Elpida, Micron and Nanya, didn't show off their DDR4 prototypes but are expected to by end 2012. With DDR4 set to hit the PC enthusiast market in 2014, are you going to make the jump to DDR4 or wait until it becomes mainstream much like many users did with the switch from DDR2 to DDR3?

i guess haswell-successor and amd piledriver's successors might support ddr4.
Well, it's pretty much up to the price TBH... Unless they prove to be a major performance booster, I'd say most people can wait. Maybe AMD's APUs might/should speed up their adoption.
Cheers!
I know that I will still upgrade them both at some point with both more RAM and SSD's,
and that should be enough for them for another 4-5 years.
By then DDR4 will be mainstream anyway, and prices would have come down from their initial price.
The only question is: How much DDR4 RAM to buy when the time is right?
Like I mentioned, I will upgrade my ram, on my main PC it will go from 4GB (what it has now) to 16GB
(my motherboard limit) since I have always at least double the amount of RAM on each PC...
Then I can safely guess that I will "need" or get a minimum of 32GB but expandable to 64GB or 128GB.
Then again the motherboards that will be compatible with this memory will also include other features... and we need to know more about them.
Anyways, this are exciting news indeed.
1. many peopel had jsut shelled out money of ddr2 based systems before ddr3 was annouced or available .
2. DRR3 did and still does cost drastically more than ddr 2
3. ddr3 has drastically higher latency compared to ddr 2 , if you take a lower speed ddr 3 module and match it to the same speed ddr2 the ddr 2 will perform better because it has lower latency
number 3 being the Biggest reasons budget minded enthusiast were not enthusiastic about ddr3.
we need latency figures along side the speed figures .
"farmville" or any other "make believe I"m a game" has not infested my computer.
As for windows 8... same as "farmville" ... or vista, windows Me...
Plus we all know that the "minimum requirements" are never the optimal specs.
i wouldnt hold my breath , at most i expect matured apu's to provide mid end performance in gaming task at most , current apu's only throw up entry level power and the cpu power has been less than entry level really because amd is using weak cores to accomadate the gpu being higher end.
though the thought of a single chip runing xbox 720 (or what ever it will be called ) level graphics at 60 fps is a sweet idea , i just don't see it happening atleast not cheaply.
at most i'd expect xbox 360 level graphics with 4x AA running 60 fps.
lol, i have a quad core, granted its on ddr2, but its still a quad core, it can handle damn near everything i throw at it, so yea, why build a new system now, even if its a bit over 2 years old,
by the time ddr4 hits the 16gb for 80$ range id defiantly consider a new pc possible.
If AMD can take advantage of the throughput benefits of DDR4, this could help level the playing fields a bit.
16gb ddr2 would cost me 2-400$
16gb ddr3 would cost me 80 at most
