[TPU] JEDEC Announces Publication of DDR4 Standard - Page 2

Do not forget the architecture changes to a bank array. No more channel garbage. DDR4 has almost unlimited scalability when compared to DDR3.

They did end up getting rid of the channels? Nice.

Yeah, the point-to-point topology will be the single best improvement over DDR3. Higher speeds and lower voltage, as well as other miscellaneous tweaks are in store, but it will be awhile before DDR4 becomes tangibly better. Just like the transition from DDR2 to DDR3, initially the high prices and near-identical performance won't make it desirable.

[guru 3D] DDR4 Memory Standard is now Final

Quote:
JEDEC announced it has finalized the DDR4 memory standard. The first DDR4 memory modules for servers are anticipated next year, but widespread adoption among consumers isn't anticipated until 2015.JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the initial publication of its widely-anticipated Synchronous DDR4 (Double Data Rate 4) standard.

According to the attached image, as compared to DDR3 1866 (30GB/S); DDR4 2133 = 34GB/S; DDR4 2400 = 38.4GB/S; DDR4 2666 = 42.7GB/S and DDR4 3200 = 51.2GB/S drool.gif

Well, I'm not that exited about DDR4, its mostly useful for servers bcos it uses a bit less energy, however, its also strictly single channel (needing some kind of special server chipset to be able to do multi channel which probably adds significant additional latency). The underlying tech is very similar and as such the speed difference, at least for first few years is not that significant.

So when will this be actually available for the consumer ? i assume "widespread adoption in 2015" means just that and not available for purchase.

I'd guess we would have to wait for chip and motherboard makers to jump on board too.

Not that excited about it personally. With the bandwidth we have now I would be more interested in somerthing with a lower latency.

Guess this means my system will last me a little longer.

I'll wait out until DDR4 starts becoming more and more adopted. Until then, this is good news for DDR3 consumers too.. just means everything will go down in price eventually (as DDR3 ram is cheap as it is)
