Samsung Electronics has announced that it completed development of the industry's first DDR4 DRAM module last month, using 30nm class process technology, and provided 1.2V 2GB DDR4 unbuffered dual in-line memory modules (UDIMM) to a controller maker for testing. The new DDR4 DRAM module can achieve data transfer rates of 2.133Gbps at 1.2V, compared to 1.35V and 1.5V DDR3 DRAM at an equivalent 30nm-class process technology, with speeds of up to 1.6Gbps. In a notebook, the DDR4 module reduces power consumption by 40 percent compared to a 1.5V DDR3 module.

I aint even got to DDR3 yet!...

There can't be any point in buying anything DDR4. I mean, if it's only going to be a few week before DDR5 comes along, might aswell save money and get that.

What the hell are you talking about? It's been 3 years since DDR3 launched. And it'll be around the same amount for DDR4-DDR5. But you go ahead and keep saying "It'll only be another week" if it makes you feel like it isn't necessary.

On another note. I really wish they let intel know so they could develop DDR4 compatibility for sandy bridge.

DDR4 is a ways off yet. afaiw the DDR4 JEDEC spec hasn't been finalised yet.
Nice to see that things are moving in the right direction, although it's early days in the development considering the specification is aiming at DDR4-4266 @ 1.05v.

BTW Nice pic - obviously using the PR method of handling RAM modules.

You most likely wont see DDR4 before Rockwell (on 16nm- Ivy Bridge's successor) due to the timeframes involved- Although I don't think there is a great deal that needs to be reworked in hardware (memory controller) between DDR3 and DDR4, although I'm not certain of this particular aspect.

I'm happy for the faster and efficiencies, but Hey! they need to chill with changing things so much as to make our Motherboards obsolete.

Put it in portable laptops, netbooks, and tablets first, where they will be most needed and well, you don't have to think about upgrading ram to find out you cannot use the latest and greatest...

Oh and I guess the Video memory DDR5 is totally different... obviously

Yah it's called GDDR5. I never really cared as it was limited by atis memory bus width afaik.

This is all good and fine, but I'm waiting for the new Rambus...

Memory bandwidth is probably the biggest anchor holding back CPU intensive tasks (video encode on Sandy Bridge for example). As the CPU takes on graphics functions, memory bandwidth is probably going to need to scale as the on-die graphics gains more shaders and higher frequencies

That seems a pretty much spot on assessment of where things are heading. With computing now heading more into the mobile space and the emphasis on jack-of-all-trades/ultra low power consumption CPU's it makes sense to develop a memory standard that uses much less power than the standard now in use and can adequately supply bandwidth to a CPU+GPU (or APU in AMD-speak) combo.
The initial pricing is likely to be higher (to recoup R&D expenses and simply because it's NEW!) and will likely find it's way into the enthusiast hardware first - standard operating procedure for new tech.

Yep. GDDR5 is based on DDR3

@red
The XDR revolution !
I can see it now, Rambutt licences the tech to everyone then five years later sues everyone for a hidden feature not included in the original licencing agreement !

This would be the same GDDR5 and same 256mb memory bus that the GTX 460 uses?

And I still don't care for it on nvidia cards either .

From the article:

....They must mean Demi Moore's law, 'don't marry in your own age bracket'

Oh i'm sorry, you don't understand sarcasm?.:rolleyes:

Thanks mate, i will :grinthumb

Your comment didn't at all make it clear it was sarcasm. I'm sorry you don't have the capacity to understand that text doesn't have a tone of voice to indicate such a thing. You need icons such as humorous emoticons or other indicators.

Please come back when you learn what sarcasm is and how it works.

The problem is that the past generation of DDR is always stocked on the market, making it slow for the new generation to flow and replace it. However this does not affects the people who always arms their own PC's, but i do agree its annoying to know that my DDR3 is old and slow even if it is 4 months since i switched to my Asus Rampage III.

or Michael Moore's Law : "Stick it to the Corporations"

The only "DDR5" is GDDR5 -a graphics memory standard that is based upon DDR3 (see earlier post for the wiki entry link). And just in the interest of completeness there is/was a GDDR4 that was used exclusively on ATI cards (HD 3870, 4670, 2900XT/Pro, X1950XTX -there may be others but not many)

Yep, DDR5 is actually GDDR5 and is 'graphics double data rate' and operates differently than the system ram.

@ Chef,
Now see that's why I put Demi in there, I knew you would have one post-haste , so I went for the low hanging fruit

I want sandy bridge so I'll be forced to get DDR3 . Honestly though this 800mhz DDR2 is pissing me off.

Hey, take another look at my first post (that's #1)...You will notice a on the end. Well in fact you won't notice the actual face because for some reason the smile code wasn't working...

You're coming very brash with things like "Please come back when you learn what sarcasm is and how it works". Manners really will help in life ya'know .

As regards to DDR4...Yeah it sounds good...Sources say 2012 for release. That's enough time for me.
