Looks like we have something else to look forward to this year
quite interested to see how they fare in market entry versus DDR3...
And how long it will take for DDR4 to surpass it's predecessor...
warlord
surpass on what.? it will be faster just "out of the box"...as ddr3 vs ddr2

GDDR4 was a flop.. So DDR4 will be also... No real advantage over DDR3

Huh? I'm assuming this is sarcasm but if not what the hell are you talking about?

Wouldn't you need a new cpu and mobo though that supports it?
iako
Yes..

"The first public demonstration of the Crucial Ballistix DDR4 DRAM modules will be held at the 2013 International CES, January 8-11th."
So which processor did they use for this demonstration then since its the 12th today and i haven't seen anything about a cpu that supports ddr4?
Or maybe i just missed it.
I thought only Haswell had ddr4 support.
Maybe they have Haswell ES?

Early DDR 3 modules ran @ 800 & 1066 mhz.. same as the last DDR 2 module speeds..

Anand speculated that its a prototype xeon chip. The computer it was running on was completely locked down so no one knows what it is and even crucial said they only had 2 boxes in their hands to do testing on. Haswell EX/Broadwell are supposed to be the first consumer Intel chips with DDR4 support but neither are slated to be released for a long time.
FYI I believe this chip was running at 2133 which was the max the board they were using supported. But they said in internal testing they were able to hit 3200. Not sure what voltage that was at, but DDR4 is supposed to start at 1.2v which is significantly less than DDR3.

hmmm according to the interwebz Haswell is only 6-8 months away from release.
If true that would burn if you just bought a high end ivy B.

It's 6 months for mobile chips, Q3 for desktop chips. Haswell-EX with DDR4 support isn't till 2014 and its launching with server parts first.

We're getting there. Although I imagine AMD will probably pull the same thing it did with DDR3 and not actually support for a like a year after Intel starts pumping out stuff. Meaning, probably be like 2015 for AMD fans.
This is why I've been holding back on an entire system upgrade. I'm still using DDR2. Before DDR2 I was using PC133. Before that, EDO.

so should we be excited or not, cause this thread is sending me mixed messages.

Early on timings might be a bit worse and speed will likely not to too different from current higher-end DDR3 modules but it supports faster data rate (If I understood correctly.) operates at a lower voltage and in time will get even faster. 🙂
(It will probably also be quite expensive when it's first released.)
Just as with DDR3 though the timings never changed much AFAIK.
(My first DDR3 kit uses 8-8-8-24 at 1800mhz, expensive but it's still working, ran at 1.95v though compared to current generation 1.5v modules.)

speed is one thing, response time is another, it gives no indication of the RAM's timing...

I'd think it's safe to assume the timings are much looser than DDR3, especially considering the claimed clock speeds.
So maybe a CAS latency of 10-14?

Where do you get that? All info at this point in time points to an early June release.

Although I wouldnt be surprised if desktop chips get pushed back to Q3 later on, but I dont think theres anything to indicate that as of yet.
