And yet despite this, the specification for LPDDR5 has yet to be completed.

Samsung has been on a roll lately with memory & storage-related announcements, and that roll is continuing today with a new DRAM-related announcement out of the juggernaut. This afternoon the company is announcing that they have completed fabrication, functional testing, and validation of a prototype 8Gbit LPDDR5 module. The company is targeting data rates up to 6.4Gbps-per-pin with the new memory, and while Samsung isn’t ready to start mass production quite yet, the company’s press release notes that they’re already eyeing it.

This is actually the first LPDDR5 announcement to cross AnandTech’s proverbial desk, so if you haven’t heard of the standard before, there’s a good reason for that. LPDDR5 is so cutting edge that the standard itself has yet to be completed; the JEDEC standards group has not yet finalized the specifications for DDR5 or LPDDR5. The JEDEC only first announced work on DDR5 last year, with the specification due at some point this year. As a result information on the memory technology has been limited, as while the major aspects of the technology would have been hammered out early, the committee and its members tend to favor holding back until the specification is at or is close to completion.

In any case, it appears that Samsung is the first to jump out of the gate on LPDDR5, becoming the first manufacturer to announce validation of their prototype. And as part of the process, they have revealed, at a high level, some important specifications and features of the new memory standard.

In terms of performance, Samsung is targeting up to 6.4Gbps/pin with the new memory. Which for a typical 32-bit bus chip works out to 25.6GB/sec of memory bandwidth. This is a 50% increase in bandwidth over the current LPDDR4(X) standard, which tops out at 4.266Gbps under the same conditions. So for a high-end phone where 64-bit memory buses are common, we’d be looking at over 50GB/sec of memory bandwidth, and over 100GB/sec for a standard 128-bit bus P

 

 

As with LPDDR4 and LPDDR4X, the main applications for this will be smartphones and tablets.

 

PCs may receive support for LPDDR5 at launch on upcoming x86-64 CPUs, unlike LPDDR4.

 

So yeah, interesting stuff. I'm not going to pretend that I know everything about this as there are definitely many bits which are unfamiliar to me. Hopefully we'll get LPDDR4, and potentially soonish, LPDDR5 in PCs. As only Intel's Cannon Lake 10nm 8th Generation dual core i3 supports LPDDR4 and LPDDR4X on the PC front.

I would expect support for it in 9th Gen Intel CPUs considering Cannon Lake supports it.

i feel like im going to get so fucked over by getting 8th gen over 9th gen, spectre/meltdown, lpddr4.. but that was the same mindset with 7th to 8th..

Just bring the fucking latency of DDR4 down already, so it's actually a complete replacement.

Every time I see "Samsung Announces" I read:

Samsung Announces DRAM price increase

[Doobeedoo]

This will be very good for new smartphones definitely. 

[Amazonsucks]

Cant wait to see an IBM z15 with 96TB of DDR5 in RAIM.

[Trixanity]

What I find interesting is that increasing the speed increases power consumption considerably so they have to do other things to bring it back down and they still managed to reduce it by 30%.

hurry up and implement this DDR4 is way to power hingry on laptops

DDR4 RAM was finalized in 2012, but it didn't begin to go mainstream until 2015 when consumer processors from Intel and others added support for it.

Obviously if the pattern holds and the estimates are accurate as to finalizing in 2018, we can hope for consumer support in 2021.
