Cool. Really looking forward to DDR4

 

What are the advantages over ddr3?

 

Faster bench number obviously, and price premium too.

I read that samsung had DDR4 ready for long time but none of the chipset maker is pushing it .

 

yea it has been a long time since DDR4 was first working on a samsung 2GB stick....maybe 3 years ago? maybe longer. Says in wikipedia. I was reading up on it several months ago. Biggest think is 16GB sticks...maybe bigger can't remember

 

DDR2 >> DDR3 was also met with big scepticism due to the same "minor" improvements in speed, plus DDR2 was cheaper. Hence it took a long time before the new RAM was embraced by the industry, motherboard and graphic card makers etc. But they eventually got there.

Same is happening right now with the DDR3 >> DDR4.
Improvements like I know of is 40% less power consumption due to running at lower voltage. 1.05-1.2V vs 1.2-1.5V for DDR3.
The cool thing about DDR4 is that the lowest DDR4 is running @ 2133MHz.

MHz-range:
DDR2: 400 - 1066MHz
DDR3: 800- 2133MHz
DDR4: 2133 - 4266MHz

Apparantly the DDR4 is coming to the stores early 2013. Hopefully the industry will not ditch these modules like they did with Samsungs

 

Gonna be a while before it's reasonably priced though.

 

If they start replacing DDR3 with DDR4 on cheap dedicated GPU's then that would be a worthwhile improvement, as well as in things like llano where the integrated GPU shares the system memory which have also shown significant improvements in graphical performance with faster memory.

However, if you have a dedicated GPU with some decent memory then this will likely be a moot selling point. The only areas I can see where it would make a significant difference would be the low end GPU market and netbooks, since they have a low enough power consumption that RAM actually becomes semi significant when it comes to battery life.

 

hopefully it can be integrated onto IB CPU's...

 

And seeing that it'll be a premium part for the first year or two, it's unlikely anyone's going to bother with DDR4 on an APU for a couple years...

 

only reason why its premium part is because no one wants to pay the extra to switch...if everyone just bought that it would drop fast. It ends up on the manufactures to force people to switch by only making DDR4 MOBOs

 

You can't just rapidly switch like that, though. The infrastructure for manufacturing that much DDR4 will take time and money to set up. I can't find any stats, but the global market probably uses in the hundreds of millions of DDR3 sticks a year, very possibly over a billion, meaning a switch to DDR4 would require hundreds of new or refitted factories. In reality, early adopters help subsidize the cost of the manufacturing switch by paying premium prices when the tech is new, then when it's in high enough demand, it becomes inexpensive because the infrastructure is there.

It would be similar to "just switching" to 4k resolutions - the technology is there, so why can't we all have 4k screens tomorrow? Because the manufacturing capacity isn't there. With things like processor updates, they build the manufacturing capacity before they release the product, but most tech doesn't work like that.

 

At least with 4k resolutions you have apple fanboys who'll impulse buy as soon as they become available to get the market going.
