DDR5 RAM Expected in 2019 but the Figures are Hardly Impressive
We love everything about RAM. Except for the Price!
We at eTeknix love fast RAM. Even more so if it has a lot of bright lights and LED’s to dazzle us. We, of course, do not love everything about it. The price at the moment is a major issue for us, however, when we hear reports of DDR5 ram emerging, our spidey sense starts tingling for new heights in computer performance.
We were recently highly impressed with Corsairs latest DDR4 offering which achieved speeds of 4600mhz. DDR5, however, could provide figures even more astonishing if the report via PcGames is to be believed.
Aging myself quite horrifically, I still fondly remember the days before dims or nimms, back to a simpler time when you had to buy RAM in 2 slots of the same value. Ahh, my Pentium 100 and it’s phenomenal 16mb of ram (upgrading from a lowly 8mb). In fact, thinking about it, it wasn’t a simpler time at all. It was a considerably more complicated time and I regret nothing to now have my 16gb of 3200 DDR4.
What can we expect from DDR5 ram?
We reported a short while ago how RAMBUS has claimed to have created the first DDR5 RAM. I should be clear at this point that there is no ‘set level’ as to what DDR5 will be. Frankly, DDR4 is still nicely new enough for the vast majority of us to be happy with what we have. At least, for the moment. RAMBUS, however, now seem to want to claim otherwise.
In the announcement, RAMBUS said: “This is the very first silicon-proven memory buffer chip prototype capable of achieving the speeds required for the upcoming DDR5 standard. Data-intensive applications like big data analytics and machine learning will be key drivers for the adoption of DDR5, with enterprise close behind.”
RAMBUS claim that DDR5 RAM base speeds will be somewhere in the region of 4600mhz. Now, this is, as above, a smidgen higher than the recently reported Corsair 4400mhz DDR4, but this is hardly a massive step forward. Frankly, when I heard announcement I was expecting 6000mhz+, not a hair over what has just been achieved. Don’t get me wrong, faster is good, but this is barely above what DDR4 is clearly capable of.
You’re being a bit harsh there!
Yes, I am, but hear me out.
Playing devil’s advocate, I should reiterate that 4600mhz is reported to be just the base level of speed. That in itself is just about double what we have in DDR4. As such, based on where we are right now today, it is very impressive. I have no doubt I’m going to fall in for coming criticism over calling this figure ‘hardly impressive’. I do therefore acknowledge that eventually higher packages will exceed 6000mhz by the time the next innovation in RAM is settled. I’m, therefore, not entirely throwing a damp towel over this. I am just surprised at the lack of hyperbole from RAMBUS. Perhaps I am far too accustomed to seeing over-estimations rather than apparent conservative ones.

I am just surprised at the lack of hyperbole from RAMBUS. I am far too accustomed to seeing over-estimations rather than apparent conservative ones.
My major caveat to not hopping aboard the hype train is that this is not expected for at least 2 years. A base rating of 4600mhz, by that point, is surely within reasonable expectations.
Now, of course, DDR5 will likely be better in areas other than just speed. To impress me to the levels of some of the hyperbole I’ve seen written, I’m going to have to hear better than 4600mhz.
More accurate analysis of Rambus DDR5 progress can be found on the eetimes website, where writers have been part of the semiconductor industry and therefore better placed to discuss a high speed wireline transeiver technology.

As we get towards higher data rates, not just clock rates discussed above, the number of deep signal integrity issues we face climbs quickly. In particular jitter specifications are now routinely a few ps.
DDR standards use a variety of techniques to transmit data faster than the clock. Dual data rate is data on the positive and negative periods of the clock, however multi-lane and quadrature techniques can also be used. Likewise OOK encoding is one bit per slot whereas 4-PAM i.e. 4 level pulse amplitude modulation is more noise sensitive but gives 4 bits per symbol.
Before downplaying a technology, please get your article in order. Yes the clock increase may be modest, but please nite data rate increases and indeed the diference between Gb/s and GB/s. Otherwise you risk coming accross as quite uneducated.
Here is a suitable quote showing how clock frequency is not a reliable figure. It is actually quite lazy to use use a figure only.
“DDR5 is expected to support data rates up to 6.4 Gbits/s and deliver 51.2 GBytes/s max, up from 3.2 Gbits/s and 25.6 GBytes/s for today’s DDR4. The new version will push the 64-bit link down to 1.1 V and burst lengths to 16 bits from 1.2 V and 8 bits. In addition, DDR5 lets voltage regulators ride on the memory card rather than the motherboard.”
To reiterate. 51.2 G Bytes per second. Thats approx 400 Gb/s. As shown in the eetimes article DDR5 offers double the throughput, similar clock and lower power.
Please do not diminish the difficulty of such data rates.
Typically when a new ram comes out, the base is of the next generation is very similar to the peak of the last. Give it some time, the important thing is that the sockets will be capable of much more when the DDR5 chips catch up.
Interesting
You all are not reading what he wrote. You are injecting your own ignorance into his article. Here I will dumb it down for you. The proposed ddr5 is not impressive. Show me a little more for my money. I even typed it slowly so you can read it.
DDR4 started with 2133Mhz and maybe it could be argued that its base was either 2133Mhz oder 2400. Eitherway lots of notebooks only shipped with 2133Mhz for a while and even now expensive notebooks are often at “only” 2666M0hz.
Intel’s officially supported speed on the first DDR4 CPUs was just 2133Mhz.
4800Mhz base should be compared to DDR4s 2400Mhz. This article reads like a child wrote it that doesn’t know any history. DDR2 to DDR3 was the same story and DDR3 to DDR4 as well. Usually low latency high end memory of the older generation was no slower than the first versions of the new. At first the benefits always are power consumption which servers and notebooks care most about. You basically get the speeds of high end desktop ram for the power consumption of the low end 2666Mhz DDR4. Beating high clocked desktop modules was never a thing for first gen DDR3/DDR4 and won’t be for DDR5
History suggests that once DDR5 is as mature as DDR4 is right now you will have 8800Mhz+.
Creo que la Memoria Ram DDR5 andarian muy bien con la NVIDIA RTX 2080Ti 2080/2070
Most manufactures have stated that DDR5 is more about capacity than transfer rate. They claim that DDR5 will allow for twice the capacity per controller of DDR4. Additionally, DDR5 4400 will probably be significantly cheaper per GB than DDR4 4400, probably not half the price, but at least 20% cheaper once crossover is reached.
One more thing, which is probably the most important. DDR5 will be a JEDEC standard. It is unlikely that DDR4 4400 will ever be a JEDEC standard. At best, if chip designers press hard enough, JEDEC might release a standard for DDR4 3600 before shipment volume crossover is reached for DDR4 4400 vs DDR5 4400.
This article is dumb, and my brain hurts!
If DDR5 speeds are to be 4600Mhz they are almost TWICE the “speed” depending on Latencies obviously.
It almost like the author doesn’t know the difference between the speed of the technology
X79 = 1600Mhz (native)
X99 = 2133/2400Mhz (native)
X299 = 2400/2666Mhz (native)
All other speeds is “overclocking”. So when you have a mem kit that says 4600Mhz ..that means ‘in a testing scenario we managed to achieve 4600Mhz with these memory modules”
Doesn’t naturally mean that you can plug these sticks in your box and expect those speeds! You must do overclocking, and even then you probably won’t see those speeds!
But from your own text DDR5 will support 4600Mhz out of the box, or perhaps I should say *right in the box. You unpack them and pop them in your DDR5 rated system and bang, 4600Mhz.
THAT IS AMAZING!
If you are “not impressed” then I don’t know what to tell you other than I’m sorry for your ignorance and uneducated stupidity!
Next thing you need to understand that “speeds” alone really is not always faster!
The first DDR4 kits, when they arrived, had insanely high latency! So much so that there was no reason to upgrade on that variable alone. Sometimes rather the opposite. I know alot of people (home users) who stuck with x79 and still are on x79, waiting on a meaningful performance gain in upgrading.
x599 will most likely be the natural step after x79.
Don’t forget most of the x79 crowd have 2400Mhz CL10 (arguably the best computer response to transferred speed compromise there’s been until 6 months ago when DDR4 finally started getting timings tighter) and most of the x79 crowd have 10 core’s 20 threads CPU’s awsell.. so to them nothing has really been worth the hassle to justify a new system this decade as of yet!
DDR5 changes that!
Speed isn’t just everything. Cost will play a huge part in acceptance.
It used to be the case that you could buy an 8GB stick of DDR3 RAM (1600MHz) for about $50 back in the day. With DDR4, the base version (Kingston ValueRAM) at 2133 MHz currently goes for about $99. For a decently spec’d version at 3200 MHz, that number goes up to $120 per stick (they come in a matched pair).
So as it is, if wanted to upgrade my system to have 32GB DDR4 RAM it would cost around 400 – 500 dollars. Judging by history, I’d expect that figure to double for DDR5 RAM.
At that rate RAM would probably end up being the most expensive component of your system, and no longer the CPU.
It should be impressive considering the price! A 4600Mhz DDR5 memory should be cheaper than a DDR4 3200Mhz and way faster!
I think DDR4 is running at 2133Mhz but it’s overclocked to achieve higher frequencies, unlike DDR5 which runs at 4600Mhz stock!
The 4600Mhz will be an impressive performance, I am eagerly waiting for DDR5 RAM.
Hope I can see it in 2019 only.
i dont think that ddr5 is going to be that much better
