all about current DDR 4 memories and upcoming ones

DukiNuki · Mar 27, 2015

hi people

this is what i learned so far about DDR4 memories .

they are currently available only for Z99 boards and they are so expensive . they currently have 4 channels and they have very little to zero impact on games even with high end hardwares . dual channel DDR 4 memories will be available with release of skylake and will eventually replace ddr 3 sticks .

is this info Correct ? they really wont affect gaming Performance ? what about ones that Skylake cpus will support ? will Dual channel version be as cheap as current DDr 3 sticks ?

1) It will not affect gaming because the best CPU's like the i5-4690K are already rarely the bottleneck.

The purpose of DDR3/DDR4 memory is simply to be store the data and be fast enough not to slow down CPU processing.

2) Dual/Quad:
I don't have information on this at all, however even if we "only" had Dual Channel it would be more than fast enough with good DDR4 memory.

3) The main point of DDR4 memory currently is because that's forced on you if you want to invest in certain new CPU's like the i7-5820K. This CPU is a pretty good value but memory and motherboard costs are too high for me to recommend to most people.

The memory in computers today is fast enough for any game... The only issue some people had with memory is that they didn't have enough... but today that is rarely true unless someone is attempting to game with a fairly old computer. The amount of real world performance gained would be barely noticeable if any at all.

When DDR4 hits mainstream the prices will come down and eventually be roughly the same as DDR3 is now. It happened when DDR3 took the place of DDR2 and it's likely to happen again. (It's just economics)

The best gaming hardware for the money right now is not the Z99 Motherboards and DDR4 memory.
I would build a system with a high clock frequency Intel Core i5 CPU and a Z97 chipset on the motherboard (and of course DDR3).

If you want to wait on building a system or upgrading, that's up to you but I believe you are correct in thinking that you wouldn't see a huge gain from the Z99 and DDR4. (As long as your CPU is up to par) The biggest gains in gaming come from better video cards.

Today, I have my doubts about the value of ddr4.
Intel ram controllers are very good.
The difference in real app performance or fps is in the low single digits.
Higher speed ram is accompanied by higher cas numbers.

Thanks for all the answers guys . SO useful . I just don't get the point of DDR4 memories . if DDR3 is working with no problem then why building something that wont impact on performance even for a little . as a Developer that's a huge waste of Investments and as a User that's a huge waste of money to upgrade for nothing but still the name makes you wanna Max Out your stuff .

if they wanted to make more money they Shouldn't have made SkyLake support both DDR3 and DDR4 . many people who understand the difference wont pay for DDR4 sticks . So i think ill go with pair of nice DDR3 sticks

thanks again guys . so hard to pick the best solutions when all solution inform you ALOT

Basically DDR4 is just part of the natural progression of DRAM evolution, while it goes back further, there was DDR, followwed by DDR2, DDR3 was originally intended to only go to 1600, and rough specs were already in place for DDR4 to 'start' at 1600 and then progress to 1866, 2133, 2400, etc. The users wanted faster DRAM and the manufacturers started pushing the envelop, before we knew it there was 1866 and then 2133. JEDEC, the organization that lays out standards was behind the times, then the manufacturers continued to push ahead and we saw 2400, 2666 out and on the market before JEDEC had even published 'standards's for 1866. By the time DDR4 finally was ready to come to market, it arrived 'starting' at DDR4 2133, the originally intended lower level 1600 and 1866 have basically been forgotten

geofelt :

The latencies are relative. If you double the transfer frequency and double the latency, you've doubled your bandwidth and you latency didn't change. There was a benchmark recently, possible from Toms, that compared several different frequencies of DDR3 along with various latencies. There wasn't a whole lot of difference, but the higher frequency higher latency memory was still faster on the latency benchmarks.

I'd be more concerned about power draw. CPUs and memory are plenty fast, such that 10%-20% difference turns into 5% differences in real world, but a 10%-20% difference in performance may require a 20%-80% difference in power draw.

DukiNuki :

Whereas DDR3 SDRAM is largely just a slight evolution of DDR2 SDRAM, and DDR2 SDRAM is a slight evolution of DDR SDRAM, DDR4 SDRAM actually alters the internal design of the memory chip quite significantly.

DDR3 SDRAM has been good for quite some time, but it cannot scale any further than it has already. Manufacturers have already abandoned plans to create native 8 gigabit DDR3 SDRAM chips or native chips above DDR3-2133.

The design changes in DDR4 allow for much higher chip density much higher data rates, and much higher availability at higher data rates, all at a reduced power consumption across the board.
