Samsung Develops Industry's Fastest 10.7Gbps LPDDR5X DRAM

Samsung Electronics, a world leader in advanced memory technology, today announced that it has developed the industry's first LPDDR5X DRAM supporting the industry's highest performance of up to 10.7 gigabits-per-second (Gbps). Leveraging 12 nanometer (nm)-class process technology, Samsung has achieved the smallest chip size among existing LPDDRs, solidifying its technological leadership in the low-power DRAM market.

"As demand for low-power, high-performance memory increases, LPDDR DRAM is expected to expand its applications from mainly mobile to other areas that traditionally require higher performance and reliability such as PCs, accelerators, servers and automobiles," said YongCheol Bae, Executive Vice President of Memory Product Planning of the Memory Business at Samsung Electronics. "Samsung will continue to innovate and deliver optimized products for the upcoming on-device AI era through close collaboration with customers." With the surge in AI applications, on-device AI, which enables direct processing on devices, is becoming increasingly crucial, underscoring the need for low-power, high-performance LPDDR memory.
Samsung's 10.7 Gbps LPDDR5X not only improves performance by more than 25% and capacity by more than 30%, compared to the previous generation, but also expands the single package capacity of mobile DRAM up to 32-gigabytes (GB), making it an optimal solution for the on-device AI era that requires high-performance, high-capacity and low-power memory.

In particular, the LPDDR5X incorporates specialized power-saving technologies such as optimized power variation that adjusts power according to workload and expanded low-power mode intervals which extend energy-saving periods. These improvements enhance power efficiency by 25% over the previous generation, enabling mobile devices to provide longer battery life and allowing servers to minimize total cost of ownership (TCO) by lowering energy usage when processing data.

Mass production of the 10.7 Gbps LPDDR5X is scheduled to begin by the second half of the year, following verification with mobile application processor (AP) and mobile device providers.

They literally only announced 9600 gbps only a month or two ago.

Here's hoping the higher end Strix Point laptops and handhelds will support this memory.

171.2GB/s on a 128bit arrangement would certainly help those 16 CUs.

Great, and they haven't even started using 3D RAM

"DRAM featuring 3D transistors has been discussed for years, but actual makers of memory have refrained from making any real announcements on the matter. However, Samsung decided to break the silence at Memcom last week and revealed some of its plans concerning 3D DRAM. As it turns out, the first 3D DRAM node is just a few years away. "

The increase in bandwidth is great for some cases, but I do wonder what is the latency/ timing values. For context, the solder LPDDR5 6000 on my laptop is showing CL timings at 60, so to push bandwidth higher, something's got to give.

Will this be as MIA as their GDDR6W chips that were shown but never produced in any meaningful numbers?
Samsung seems to have constant yield issue problem with their chips - both compute and memory.

They announce these way in advance and these either don't pan put and are quietly shelved and never used or it takes a long time before they reach respectable yields.

I bet that Samsung's GDDR6@24Gbps will be used in the next generation of both AMD and Nvidia GPUs, in mid-range and entry-level models.

That's my point. A lot of time will have passed IF and WHEN it will actually be used.

6W is a slight upgrade over 6X. I could see it being used in the next gen upper-mid-range while 7 is reserved for the high-end.

Considering these would be used in high end smartphones you're almost certainly 100% wrong, also the fastest LPDDR5 varaint before this was SK Hynix's 9600 MT/s one used for Dimensity chips, there's no 9600 MT/S LPDDR5x versions that I know of ±

They'll probably match top end LPDDR5x before long.

On their website it says "sampling", which naturally means it's in the hands of AMD/Nvidia maybe intel. But It seems to me that GDDR6W is relatively more complex than conventional GDDR6.

"The memory maker says that usage of FOWLP packaging allows for the reduction of the thickness of GDDR6W packaging to 0.7 mm, down from 1.1 mm in the case of standard GDDR6 chips, making it easier to cool them down. While common sense says that FOWLP packaging is more expensive than traditional BGA packaging, it is unclear how significantly the former is more costly than the latter. "

I thought it was Samsung, but it was Micron that recently announced 9600MT/s LPDDR5X

They're not selling it even now, at least if you look at their parts catalog on the site ±
www.micron.com/products/memory/dram-components/lpddr5x/part-catalog
Maybe they're waiting for more handouts "aid" from the US govt o_O

I've also not seen any other QC mobile SoC with 9600 MT/s speeds using LPDDR5x & IIRC Dimensity 9300 uses LPDDR5T almost(?) exclusively.

The fastest available(?) LPDDR is already at one half of the speed of the fastest available GDDR, I find that amazing.

24Gbps GDDR6. Nearly two years ago. Sampling back then. Sampling today. I very much doubt AMD/Nvidia/Intel have been evaluating this for nearly two years without a product in sight. My conclusion is that Samsung is full of BS and no one is sampling either 24Gbps or faster GDDR6W. Vaporware.

The highest speed Samsung actually has in mass production is 20Gbps if their website is to be believed.

how does this compare to CAMM memory??

These chips may become part of LPCAMM modules one day. That will be the low power variant of CAMM.
