DDR3 to DDR4 Transition Chalked-out, DDR4 in 2012

[imperialreign]

It doesn't go quite like that. All SDRAM-DDR irregardless of the generation move the exact same amount of data bits per clock cycle. What makes the difference is DDR2 has higher freq (= more clock cycles per second) than DDR1. And DDR3 pushes even more. And since the length of a clock cycle shortens when frequency goes up, latencies don't become a problem.

damn . . . y'know, I still get confused sometimes as to the intricacies of DRAM operations


although, I still rest by my earlier example and bench that I posted showing that solid mid-range DDR3 can tangle with some of the best DDR2 offerings. Yeah, I've seen DDR2 pull some better read/write latencies at lower clock settings; but considering my timings, and the very, very mild OC (1600-stock vs 1800-OC), there's still a fathom of potential left.


Now, I just need to go liquid cooling so I can start fiddling further with 4GHz+ CPU clocks

DDR4?!? WTF! What happened to just going to DDR5?!?

LoL, sorry no one else had done it yet ; )
I'm suprised they are putting DDR4 that far out. With so much hype with DDR5 on GPUs.

well . . . technically, there are slight differences between SYS DRAM and GPU DRAM. it's nothing dramatic, really, but the differences equate to GDRAM being developed for use and access by GPUs; they respond faster, tend to be more efficient and are capable of running at much faster speeds than their equivalent SYS DRAM components. The biggest difference between the two varieties, is that GDDR# can turn on a MEM bank and read from it within the same clock cycle, whereas SYS DDR# can't.

Otherwise GDDR# operates at a theorhetical level the same as DDR#.

I understand there are differences. I don't know much into the details. I was just saying to the average consumer. In a year they will be looking at GPUs running on DDR5 and still be sitting with DDR3 as the big thing in their systems. Don't we already have enough confusion out their for them. LoL

where is DDR4

Where is ddr4? It is now 2013 and I have seen nothing mention or for sale. Too bad gddr5 isn't being used for pc memory since it is the fastest out there.

Micron had some running at CES... CES 2013 - Micron displays world's first worki...

Nice thread necro as well.

Delays: (one of many news articles on it) http://www.techhive.com/article/2034175/adoption-of-ddr4-memory-facing-delays.html

Haswell-E to use DDR4 memory: http://www.tomshardware.com/news/Haswell-E-DDR4-Ivy-Bridge,22022.html

It's coming, just not on schedule like most PC tech.

Surprised I got a response. I hit the thanks button, but I thought I would say it also. Thanks, very much appreciated.

Sounds about as useful as a third leg... They could make DDR 5000.
Won't make a difference, because no systems will do any better due to it..
Only people who want Epeen will buy this stuff.
People who know how useless it is, won't..

No, not really. It's the progression of things. DDR4 is the next step. It will use less power and offer more bandwidth for future systems. Look at DDR, DDR2 and where they sit performance-wise today. Besides, we wont' see DDR4 until Haswell-E later next year. It won't be mainstream until 2015.

Yea, but now a days, I could use ddr3 1600 or ddr3 2000 and it won't make a difference..
So DDR4, I'm not holding my breath. XD

 

[McSteel]

Yes, and it hardly made any difference if you used DDR-333 or DDR-400, DDR2-677 or DDR2-1066... It all stayed inside 5%, for most applications and games.

But comparing DDR-400 and DDR2-1066, what do you get?

So you just signed up for the forum to dig out from the graves an ancient thread...
Btw GDDR5 is based on DDR3 but is specially designed for graphics intense tasks.
