Forums - PC Discussion - DDR5 Could Reach The Consumer Market As Early As 2019

numberwang on 22 September 2017

Mmhh DDR4 is plenty fast already. All the critical components have their own RAM anyway (CPU cache, GPU RAM)

I clicked here thinking it was Dance Dance Revolution 5. Now I'm dissapointed. :(

Same here :(

It makes me wonder how quickly the laptop I purchased this year will become obsolete!! It's interesting thinking of how laptops will change in power in only 5 years.

You got your new laptop!
What did you end up with?

I got it a few weeks ago. I ended up with the ASUS ROG Strix GL753VD-DS71 17.3

Am I crazy or was DDR3 the standard much longer than DDR4 is going to be? I seem to recall DDR3 being the standard for at least 7 years, we've only had DDR4 for like 3 years so far. 

On a side note, Nvidia's Volta GPU line in 2018 is supposedly using GDDR6. Now that was a long standard, GDDR5 has been used since 2008, when AMD used it in their HD 4870 GPU.

4k+ gaming and machine learning are very bandwidth intensive.
There is now a real need and push for high bandwidth solutions, so we get them.

I wonder how well AMD's Infinity Fabric will scale under DDR5.

Chances the ps5 will have this?

Whats your dream scenario? :P I think they'll surprise us with the amount of ram, kinda like the PS4 announcement. When it is announced early 2020 16-24GB gpu cards should be commonplace.

Also, DDR5 is too soon, I just got 16GB of DDR4 last year! Only 2400, wish I got higher but it was when people still mistakenly said higher frequency didn't matter.

DDR5 is not too soon.

DDR3 was on the market for a long ass time... And we got used to that.

Memory bandwidth is getting more important because of powerful integrated graphics, not just on Desktops... But Notebooks, Tablets, Phones and other devices... And to feed that we need faster memory bandwidth.

Also... Higher Frequency Ram has always mattered. Well. Since we moved to on-die memory controllers anyway.
Before that... You were often limited by the FSB speed anyway.
I.E. Having a Core 2 Duo with 800mhz FSB and running Dual-Channel DDR2 1066mhz memory isn't going to suddenly change that FSB bottleneck.
(FSB = 10.6GB/s, Ram = 17GB/s)

I know some may not realize the significance of this, but it's a big deal. It pushes consumer RAM development up a year, while also! So that's GDDR6 in 2018 (thank you, Volta), with DDR5 in 2019!

Console fans - pay attention!

Do you think RAM technologies for CPU and GPU will ever converge or at least be on the same chip? Or are they just too different? Would be cool if we had completely unified RAM some day with a universal interface. Imagine just taking 2GB RAM from your CPU and plug it into your graphics card because you need more RAM for that now.

They have converged. Sort of.
Low-end GPU's used to come bundled with DDR2 or DDR3 Ram. Desktop chips, not GDDR memory chips.

However... The reason why we won't see something like GDDR5 or GDDR6 memory on the desktop as system memory is actually due to a multitude of reasons...
System memory needs to be low-power... And they often have low latencies as that is important for CPU performance.

GPU's however need all the bandwidth they can get and will drive up clockrates and latencies to achieve that... They also typically need very complex memory controllers... And that can also add a ton of power consumption and cost.

Playstation 4 uses the same memory for both, its cpu & gpu.

It runs with GDDR5.

It also comes with DDR3.

Id love to see a APU equal to a PS4 or better, for cheaper than a "intel cpu + nvidia gpu" is.

With Ryzen AMD are close enough, that the differnce in cpu tech is a meh, between the two.

If your cpu comes with a gpu equal to a ps4 as well? alot of people wouldnt buy intel anymore.

Ryzen Raven Bridge APU's with 704 GCN "Vega" based GPU cores is pretty much your PS4 in an APU.


JRPGfan said:

Theres also some advantages to haveing both cpu+gpu on the same memory.

It allows for "heterogeneous computing".

Think of it this way, right now all your x32 bit programs you run, do so mostly via the cpu.

But the cpu isnt always the most effecient way to do certain tasks, some your gpu can do better.

Nvidia/amd have programs that run more effective on the gpu, than a cpu (like encodeing movies and such).

However  these programs then dont use the cpu, they are a "either-or" situation.

What you have described can easily be done without Heterogeneous computing.

In-fact... You can also have Heterogeneous computing  with split memory pools.

but they haven't even fully utilize ddr4 yet. wtf?

It is still 2 years away from releasing.
And it will still take several years more to transition over.


CGI-Quality said:

As was DDR3. Doesn't mean we should stagnate and not march forward. :p

Exactly.

Damn DDR6 already around the corner.. well 2 years is still a long time. Only got my PC in Feb with 16 gigs of DDR4 3000 sticks. It hurts however its good for the industry. Next gen consoles can start looking past DDR4/GDDR5 ram.

Zero. This is System RAM. PS5 will have either G5X, G6, or HBM2.

Not zero, the PS4 has a small pool of DDR3, so if the PS5 launches late, they may do a similar thing with DDR5.

5% chance at max.

You're talking about the Pro. They added one stick of non conventional RAM for stuff like multitasking. Not gaming. Plus, considering it was added to an iterative console, I don't expect that with the launch of a next gen PlayStation. In fact, I doubt Sony or Microsoft use any form of DDR5 in next gen machines. So I stand by that 0% until I hear otherwise.

The base PS4 has 256MB of DDR3.
The PS4 Pro does have 1GB of DDR3 though.

My less than or equal to 5% chance remains.

Yeah, on the base PS4, there's 256MB of DDR3 for video encoding (something I bet they won't need to do for next gen machines). No non conventional RAM (DDR). 

I don't think it will happen.
It is possible though.
