DDR5 demo in silicon at 4400, 6400 to come

[porina]

Cadence this week introduced the industry’s first IP interface in silicon for the current provisional DDR5 specification developed by JEDEC. 

Source: https://www.anandtech.com/show/12710/cadence-micron-demo-ddr5-subsystem

 

Ram and IMC built to DDR5 specs have been demonstrated working at 4400 speeds. A nice boost from what we have from DDR4 now, outside of extreme OC modules anyway. If core counts continue to rise in consumer CPUs, this should help out a lot without requiring more ram channels. However there's a bit of a wait, systems aren't due until later next year, and volume taking over from DDR4 not until 2022. Maybe this'll be a good time to tie up with the next PCIe iteration.

 

Click through for pictures and more info. There's not really a good way for me to include more short of excessive copy pasta.

I for one can't wait to pay even more for RAM than the currently outrageous prices!

249$ for 8GB DDR5 or GTFO

Thats the price you pay if you want it, or just stay with older ram.

The test items were done on 7nm process, so hopefully the cost per GB will improve a bit.

Wow, DDR5 is coming soon and I still use DDR2. Only 3 of my systems have even DDR3, and I don't own a thing with DDR4.

pls no.

2020 for Server and probably 2021 before we see any in the consumer space. So it's at least 2-3 years away still.

Honestly DDR4 wasn't much of a benefit from DDR3 and in real world applications the effect is irrelevant, you can force a difference via benchmarking but ultimately DDR4 was a waste.

 

Not to mention my DDR4 can be clocked to 2933 merely with XMP settings making the average stick of DDR4 only slightly faster even on paper

For a lot of applications, power reduction alone helps.

 

Recognising my uses aren't typical, DDR3-1600 was available for a lot of DDR3 era, and bottlenecks the crap out of Haswell/Broadwell. DDR3-2400 was only available much later on. Even basic DDR4-2133 isn't great, but was getting into ok territory at 3200, for quad cores. If core counts go up, we either need more channels, or much faster ram. 4400 would be getting into the "nice" area for fast quad core, and slower 6 cores. 6400 could be adequate for 8 cores or so. All this assuming dual channel, and doesn't include Ryzen as it is too slow in my uses for it to matter.

You mean DDR3-2933? Not really fair to compare it to DDR4-3200 which is plentiful from early on at low cost. Probably more fair to compare it to the 4000+ DDR4 modules, which already encroaches on base DDR5 speeds. There's could do, just about, if everything is ok. And there's doing it as a basic standard.

So, they can make DDR5, but can't fix the DDR4 shortage?

As if the production capacity being used to make DDR5 samples would do anything meaningful to remedy the DDR4 shortages.

DDR5 is in proof of concept stage. They can make it work in a lab somewhere, but are nowhere near trying to do it on volume. The spec for it isn't even final yet! It isn't going to make any difference to DDR4 for a long time.

DDR4 was never really low cost, when it launched it was expensive and it has been expensive for quite a while, there might have been a 3-6month span that it wasn't overpriced but regardless calling it low cost is laughable

[Dabombinable]

The latency will probably shit though, as it was with at the launch of every SDRAM version.

[DoctorWho1975]

Ohhhh, DDR5-4400 + Ryzen 3 in 2019(maybe former, certainly latter)? Hold on.. I need to get some vaseline.

I mean the absolute latency is somehwta comparable to first gen ddr3 so it isn't THAT bad given the frequencies. However as with every new memory tech the timings are likely very loose and can probably go much lower

Seems the name is Genoa and it's likely 2021 before we'll see DDR5 from AMD. Maybe late 2020 from Intel in Consumer.

[Mooshi]

Pair 6400mhz with an apu, so many frames your PC will fly away!

Geesh, let me finish first.

Let's be honest here. They are likely price fixing.

Can't really stay with older ram if the new platform doesn't support it

[captain cactus]

Nice that we have fast RAM chips, now for some bad-ass memory controllers on the CPU that can officially handle it...

[Warboy]

So what you're saying is....This might be ready when Intel has 10nm working....
